Short textbook on the disciplines of comparative biology.
Stridulation is the most common method of sound production in Coleoptera, with approximately 17 types recognized across more than 30 families. In this study, two types of ventrite-femoral stridulatory systems are identified and described within the subtribe Hylobiina, distinct from those known in Coleoptera and other Curculionidae. System type 1 is...
Aim
To compare mammal phylogenetic regionalisation with previous biogeographical maps obtained from the distributional overlap of endemic taxa, considering evolutionary affinities and phylogenetic uniqueness. To test whether there is correspondence between areas of endemism at different spatial scales and phyloregions, driven by unique species or p...
Los patrones de riqueza resultan de la superposición geográfica de los nichos ecológicos de múltiples especies.
El conservadurismo filogenético del nicho ecológico y la dispersión son procesos esenciales para entender patrones geográficos en la riqueza de especies. Aquí actualizamos la teoría del ensamble biótico en la Zona de Transición Mexicana (...

La enseñanza de la biogeografía es relativamente compleja, pues involucra conceptos y métodos de diferentes disciplinas y para muchos estudiantes es demasiado “teórica”, sin una conexión clara con la realidad biológica. Para mejorar su enseñanza y como resultado de invitar a...
Anthopleura is one of the most speciose genera within the family Actiniidae. This genus is particularly characterized by its members having both verrucae on the column and acrorhagi on the margin. In the region of the Baja California Peninsula , in the Mexican Pacific, six species of Anthopleura have been documented, which are relatively well defin...
Gelatinous zooplankton constitutes a polyphyletic group with a convergent evolutionary history and poorly known biogeographical patterns. In the Gulf of Mexico, a region with complex geological, hydrological, and biotic histories, the study of this group has been limited to taxonomical and ecological aspects. In this study, we implemented a track a...
The Mexican Transition Zone is a biogeographically complex area where old and new lineages of Neotropical and Nearctic affinities overlap. Its biota was assembled by successive dispersal events of cenocrons, which are sets of taxa that dispersed during a given time interval from both North and South America and then diversified in the area. The Mex...
A total of 45 flea species, assigned to 22 genera, are documented for the state of Chihuahua, Mexico. Fourteen records are new for the state, five species are recorded for the first time for the country and the state, and the number of species of Mexico is increased to 177 species. Chihuahua now has 25.4% of the total flea species registered for th...
Anthopleura is one of the most numerous genera within the Actiniidae family. This genus is particularly characterized by its members having both verrucae on the column and acrorhagi on the margin. In the region of the Baja California Peninsula, in the Mexican Pacific, six species of Anthopleura have been documented, which are relatively well define...
We studied communities of leaf litter weevils along a 2000 m elevation gradient in El Cielo Biosphere Reserve, northeastern Mexico, an area where Nearctic and Neotropical biotas overlap. After achieving high inventory completeness (0.922 site sample coverage), we encountered 81 weevil morphospecies, of which 55 were known to be leaf litter speciali...
Background
The niche conservatism hypothesis postulates that physiological and phylogenetic factors constrain species distributions, creating richness hotspots with older lineages in ancestral climatic conditions. Conversely, niche convergence occurs when species successfully disperse to novel environments, diversifying and resulting in areas with...
En 1998 se publicó el primer volumen de Biodiversidad de Artrópodos Argentinos (BAA) (Morrone & Coscarón, 1998), que fue continuado con el volumen 2 (Claps et al., 2008a) y los volúmenes 3 y 4 (Roig-Juñent et al., 2014a, b). Estos dos nuevos volúmenes incluyen dos capítulos especiales y 50 capítulos donde se actualiza la información de distintos ta...
Los métodos filogenéticos clásicos se basan en el principio de parsimonia. Este principio también es llamado la “navaja de Ockham”, en honor a William de Ockham (1285-1348),
aunque hay diferentes autores que han propuesto enunciados similares. En términos generales, la parsimonia (o simplicidad) implica que las teorías que son más simples, que requ...
The biogeography of hydrozoans encompasses a broad scope of study that involves various challenges due to their diverse distributional strategies and life cycle characteristics. This
work aims to study the biogeographic patterns of hydrozoans in the Gulf of Mexico. Occurrence records on hydrozoans were compiled through the Global Biodiversity Facil...
The Tres Marías archipelago in the central Mexican Pacific is a protected area that has a complex geological history due to its tectonic setting. This study describes an integrative analysis of the biogeographical affinities of the biota inhabiting the islands. A biotic component analysis showed a close relationship between the islands and the Paci...
We performed a critical review of the historiographical studies on biogeography. We began with the pioneering works of Augustin and Alphonse de Candolle. Then, we analyzed the historical accounts of biogeography developed by (1) Martin Fichman and his history on the extensionism-permanentism debate; (2) Gareth Nelson and his critique of the Neo-Dar...
The biotic assembly of the Revillagigedo Archipelago, Mexico, was
analysed under an evolutionary biogeographic framework. We
undertook a parsimony analysis of endemicity with progressive character elimination of 194 plant and animal species, which allowed us to identify the archipelago as a complex area or node where Nearctic and Neotropical biotic...
The Mexican Transition Zone (MTZ) has become a key concept that has promoted the consolidation of an integrative field of research. We reviewed the scientific publications on the MTZ with bibliometric tools to detect trends through time and analyze the conceptual structure and historiographic citation. We also performed a content analysis consideri...
Biogeographical transition zones are areas of overlap, replacement or partial segregation between different biotas, which are sets of taxa sharing similar geographical distributions as a result of a common evolutionary history and ecological affinities. Transition zones occur in a few particular areas of the world where historically contingent proc...
Distributional, phylogenetic, molecular, and paleontological data may be integrated to discover biogeographic patterns exhibited by the organisms. Cladistic biogeography uses information on the phylogenetic relationships between taxa and their geographic distribution to infer a sequence of area fragmentation. Brooks Parsimony Analysis (BPA) was per...
The Neotropical species of the subgenus Ceratina (Zadontomerus) Ashmead are revised. We recognize seven new species, giving a total of 10 species for the region: Ceratina (Zadontomerus) capitosa Smith, C. (Z.) ignara Cresson, C. (Z.) nautlana Cockerell, C. (Z.) kopili new species, C. (Z.) basaltica new species, C. sapphira new species, C. (Z.) indi...
Willi Hennig's (Beitr. Ent. 1960, 10, 15) Die Dipteren-Fauna von Neuseeland als systematisches und tiergeographisches Problem applied a phylogenetic approach to examine the distributional patterns exhibited by the Diptera of New Zealand. Hennig showed how phylogenetic trees may be used to infer dispersal, based on the progression and deviation rule...
El nicho ecológico define el contexto en el que se diversifica un grupo. Muchas características del nicho fundamental pueden conservarse en el tiempo, resultando en que los nichos de especies relacionadas entre sí, suelen ser más parecidos que los de especies distantes. Esto es la Conservación Filogenética de Nicho y tiene repercusiones biogeográfi...
An interim hierarchical classification (i.e. biogeographical regionalisation or area taxonomy) of the world’s terrestrial regions is provided, following the work of Morrone published in Australian Systematic Botany in 2015. Area names are listed according to the International Code of Area Nomenclature so as to synonymise redundant names. The interi...

Climate and evolution (Matthew, 1915) represents an important contribution to evolutionary biogeography, that influenced several authors, notably belonging to the "New York School of Zoogeogra-phy"-a research community including Matthew, Schmidt, Myers and Simpson-accepted Matthew's "Holarcticism" (north temperate centers of origin) and the permane...
There are several biogeographic regionalizations of the Chihuahuan Desert province, which differ in the criteria used, and the names and categories given to the different biotic units recognized. We compared maps of these biogeographic regionalizations, detecting similarities and differences in the units recognized, and searched for endemic plant a...
The distributional patterns of the species of the mollusc subclass Vetigastropoda were analysed using the panbiogeographical method of track analysis. We analysed distributional data of 434 species and 72 genera of the world obtained from specialized literature and records in 12 malacological collections. We constructed the individual tracks for th...
A list of 35 species of the genus Pheidole distributed in the state of Puebla, Mexico is provided, based on literature
reports and specimens from regional collections, and complemented with diagnoses, distributional, biological, and
taxonomic comments. Pheidole hirtula Creighton, 1958 is synonymized under Pheidole obtusospinosa Pergande 1896,
becau...
We provide a map and shapefile of the 57 biogeographic provinces of the Neotropical region. Recognition of these provinces is based on their endemic species, but their delimitation on the map is based on ecoregions combining climatic, geological, and biotic criteria. These provinces belong to the Antillean, Brazilian and Chacoan subregions, and the...
The systematics of Megalopodidae is not adequately known, in spite of it being a relatively small group of phytophagous beetles. The first phylogenetic analysis of Megalopodidae with a comprehensive generic representation (25 genera of 30 described, 10 subgenera and 77 species) is undertaken. A parsimony analysis under equal and implied weights was...
Analysis of the biotic assembly of the Mexican Transition Zone (MTZ) is challenging because of the convergence of taxa with different origins and biogeographical histories. The typical Neotropical cenocron corresponds to genera widespread in South America that might have dispersed to the MTZ in the Pliocene–Holocene. It has been exemplified with di...

The Triatoma phyllosoma species group includes 17 species of kissing bugs, most of them implicated in the transmission of Chagas disease in the Americas. The species of this group are T.). The validity of some species of the group was uncertain, because of both cryptic species and hybrid occurrence. Species exhibiting these particularities were for...
The Transmexican Volcanic Belt (TVB) and the Balsas Basin (BB), situated in central Mexico, stand out for their species richness and endemism. Documenting patterns of distribution of endemism is relevant, since species restricted to an area may become sensitive to the modification of their environment. The aim of this study was to identify areas of...
Hace casi 50 años me enamoré de la biología evolutiva, gracias a mi maestra de sexto grado de la primaria que me impulsó a leer El origen de las especies. Nunca imaginé que años más tarde terminaría siendo profesor de biología en la Universidad Nacional Autónoma de México
There are ca. 40 biogeographic regionalisations of the Baja California province, that differ in the criteria used and the names and categories given to the different units recognised. Maps of the biogeographic regionalisations of the Baja California province were compared, detecting similarities and differences in the units recognised, and the name...
The biogeographic contributions of Léon Croizat (1894–1982) and the conflictive relationships with his intellectual descendants and critics are analysed. Croizat’s panbiogeography assumed that vicariance is the most important biogeographic process and that dispersal does not contribute to biogeographic patterns. Dispersalist biogeographers criticiz...
The genus Cenophengus LeConte (1881) includes 27 species, distributed from southern United States to northern Costa Rica. In order to test the monophyly of Cenophengus, a cladistic analysis based on 81 morphological characters, 28 species of Cenophengus and 27 outgroup species was conducted. A clade supported by three synapomorphies corresponds to...
The southwestern Andes of Peru harbor a hidden taxonomic diversity of reptiles. We describe a new species of Liolaemus Wiegmann (Iguania: Liolaemidae) from xerophytic environments of the southwestern slopes of the Andes of Peru, 2,400-2,900 m asl. The new species, previously considered to be a population of L. insolitus Cei, exhibits unique diagnos...
Some recent contributions to the biogeographic regionalization of the Páramo province are reviewed and compared. As a result, a consensus regionalization is proposed, recognizing 6 subprovinces and 11 districts: Páramos del Norte subprovince (Sierra Nevada district), Cordillera de Mérida Páramo subprovince (Venezuelan Páramo district), Páramos de l...
Evolutionary biogeography identifies areas of endemism and establishes their relationships with other areas, providing the information required to develop a hierarchical system of natural regionalization. The closely related geological and biological evolution of the planet is manifested in the existence of endemic biotas, as result of geographical...
Some species of parasites use highly vagile organisms as definitive hosts, and this may influence the geographic distribution and historical diversification of both hosts and parasites, shaped by common biogeographic processes. Acanthocephalans are a group of endoparasites, some of which use highly vagile migratory birds as definitive hosts. The ob...
Since the 19th century, 2 factors stood out during the studies of the complex species distribution in the central Mexican mountain ranges: the acknowledgment of biotic regions and the congruent distribution of widespread taxa. Such patterns were subsequently confirmed. However, towards the late 19th century and early 20th century, the acknowledgeme...
The genus Isodacrys Sharp, 1911 is revised. Twenty species of the genus are recognized ranging from south United States of America, Mexico, Guatemala and Honduras of which eight are herein described as new. These species are Isodacrys (Mexico: Oaxaca). Insights into the monophyly of Isodacrys and its phylogenetic relationships with other Tanymecini...
Adult worms of the genus Floridosentis are endoparasites of marine fishes of the genus Mugil and are broadly distributed in the Americas. Currently, Floridosentis includes two species, F. mugilis, distributed in the Gulf of Mexico and along the Atlantic Ocean coast, and F. pacifica, restricted to the Pacific Ocean coast. The aim of this study was t...
Introgression and incomplete lineage sorting (ILS) are two of the main sources of gene‐tree incongruence; both can confound the assessment of phylogenetic relationships among closely related species. The Triatoma phyllosoma species group is a clade of partially co‐distributed and cross‐fertile Chagas disease vectors. Despite previous efforts, the p...
Gonzalo Halffter developed the concept of a transition zone in Mexico during the mid-twentieth century, when he superimposed the distributional patterns of different groups of Coleoptera, finding that some groups share a common biogeographical history. The complexity of the Mexican biogeographical patterns had already caught the eyes of nineteenth-...
The integration of genetic, morphological, behavioral, and ecological information in the analysis of species boundaries has increased, allowing integrative systematics that better reflect the evolutionary history of biological groups. In this context, the goal of this study was to recognize independent evolutionary lineages within Euphonia affinis...
Evolutionary biogeography aims to discover biogeographic patterns exhibited by plant and animal taxa and to assess the historical changes that have shaped the assembly of biotas. One of these biotas is found in the Neotropical region, which has been described, delimited and regionalized by several authors since the 19th century. Important contribut...
Halffter’s theory of biotic assembly of the Mexican Transition Zone is a coherent set of hypotheses corroborated by numerous studies on plant and animal taxa, which may serve as a model to analyze the other major transition zones of the world (Saharo-Arabian, Chinese, South American, and Indo-Malayan), as well as transition zones at smaller scales....
A biogeographic transition zone is a geographical area of overlap, with a gradient of replacement and partial segregation between different biotas (sets of taxa sharing a similar geographic distribution as a product of a common history). It is an area where physical features and environmental conditions allow the mixture and co-occurrence of specie...
Most of the authors involved in the theoretical development of evolutionary biogeography assume that dispersalism, panbiogeography, cladistic biogeography, and phylogeography represent alternative approaches. Instead, I consider that different biogeographic methods may be used to answer different questions, which are different steps of an integrati...
The Mexican Transition Zone is the area where the Neotropical and Nearctic regions overlap. In its strict sense followed in this book, it corresponds to the moderate- to high-elevation highlands of Mexico, Guatemala, Honduras, El Salvador, and Nicaragua. This area is considered a transition zone between the Nearctic and Neotropical regions, so from...
Several authors have considered that the complex area where the Neotropical and Nearctic biotas overlap corresponds to a transition zone. In the strict sense that is followed in this book, the Mexican Transition Zone includes the highlands of Mexico, Guatemala, Honduras, El Salvador, and Nicaragua north of Lake Nicaragua, whereas northern Mexico, t...
The biota of the Mexican Transition Zone was assembled through the successive dispersal of four cenocrons from North and South America and their incorporation to the Paleoamerican biota, which was the original North American (Holarctic) biota that extended in Mexico in the Jurassic-Cretaceous. The Mexican Plateau cenocron dispersed to southern Nort...
Cladistic biogeography is an evolutionary biogeographic approach that infers area relationships by comparing area cladograms derived from different phylogenetic hypotheses. The South American freshwater ichthyofauna is enriched by an extraordinary number of marine-derived lineages, presenting its own phylogenetic and biogeographic patterns. Here, w...

The Austral High Andean area extends from south-eastern Mendoza, Argentina, to the southernmost tip of South America in the form of isles on the peaks of the Andes range. The objective of this biogeographic regionalisation study was to characterise this area. Individual tracks were made on the basis of the distribution maps of 232 species of vascul...
This book presents an evolutionary biogeographic analysis of the Mexican Transition Zone, which is situated in the overlap of the Nearctic and Neotropical regions. It includes a comprehensive review of previous track, cladistic and molecular biogeographic analyses and is illustrated with full color maps and vegetation photographs of the respective...
Mexico's incredible specific and ecosystemic diversity places it among the megadiverse countries of the planet. The biogeographic patterns exhibited by the taxa of the country also show a remarkable complexity. The northern part of Mexico is located in the Nearctic region, whereas the southernmost part belongs to the Neotropical region. Between bot...

We provide a key to the eight genera of the tribe Tanymecini distributed in Mexico. Habitus photographs of all genera are included as are photographs of various other key characters. A brief synopsis of each genus is included as well as a list of the species recorded for Mexico. The species Minyomerus languidus Horn and Pandeleteius championi Howde...
The rapid degradation of freshwater habitats in southern South America may cause the extinction of the endemic species of Aegla , as well as other freshwater species and components of riverside environments related to them. Information on the distribution of species and their conservation status is essential for developing conservation strategies....
Entimus serpafilhoi, a new species of the weevil genus Entimus from southeastern Brazil is described. It is distinguished from other species of the genus because it lacks the green, blue and gold iridescent scales typical of most other species. Superficially this species is similar to E. arrogans, which also lacks such scales, but the phylogenetic...
A test of the biogeographical regionalization of the Mexican Transition Zone (MTZ) is presented, resulting from a Parsimony Analysis of Endemicity (PAE) based on the distributional patterns of 575 species of the family Curculionidae. The analysis was carried out in three stages. First, a PAE was carried out to define a general regionalization schem...
Application of phylogenetic indices in the definition of conservation priorities in the northwest Andes paramos. Páramos are High Andean ecosystems that harbor a diverse biota and have high endemicity, because of their extreme environmental conditions. We used different phylogenetic indices to define conservation priorities in the paramos of the de...
Several studies on the geographical limits and regionalization of the Neotropics have recognized this region as a biogeographical unit. Recent regionalization proposals recognize the existence of a Mesoamerican dominion within the Neotropics, extending from the northern portion of the Mexican Pacific coast into the lowlands of south-central Mexico...
Neff alleges that evaluations of scientist performance by Mexico's National System of Researchers (SNI) undermine the utility of science in Mexico. Using information from interviews with Mexican ecologists, he suggests that evaluations that use journal impact factor (IF) as a proxy for quality is flawed and relinquish control of science policy to d...
We identified biogeographical districts in the Páramo biogeographic province, in the north-western Andes of Colombia, Ecuador and Venezuela, including the Sierra Nevada de Santa Marta in Colombia, above 3000 m ASL. We applied a parsimony analysis of endemicity (PAE) to 8418 distributional data of 4644 vertebrate and angiosperm species, distributed i...

The biogeographical and phylogenetic patterns of Aegla Leach, 1820 were analysed integrating track and cladistic biogeographic methods. We obtained 73 individual tracks, 10 generalised tracks and three nodes. Two taxon-area cladograms were constructed based on previous phylogenetic trees published for Aegla and Brooks Parsimony Analysis (BPA) was a...
en Ecological niche models (ENM) have been used to reconstruct potential distributions during the Last Glacial Maximum (LGM)—or other time periods—and this use is increasingly common in zoological studies. For this reason, we urgently need understanding factors affecting these predictions. Here, we examine how the use of different Global Circulatio...
