Aim: Two main biogeographical hypotheses have been proposed to explain the Mediterranean-Turanian disjunct distributions exhibited by numerous steppe-dwelling organisms, namely (a) dispersal during the Messinian salinity crisis (∼5.96-5.33 Ma) followed by range fragmentation and vicariance, and (b) Pleistocene colonization and recent processes of p...
Disentangling the relative role of environmental filtering and spatial processes in driving metacommunity structure across mountainous regions remains challenging, as the way we quantify spatial connectivity in topographically and environmentally heterogeneous landscapes can influence our perception of which process predominates. More empirical dat...
Postdivergence gene flow can trigger a number of creative evolutionary outcomes, ranging from the transfer of beneficial alleles across species boundaries (i.e., adaptive introgression) to the formation of new species (i.e., hybrid speciation). Although neutral and adaptive introgression has been broadly documented in nature, hybrid speciation is a...
Complex bulk samples of insects from biodiversity surveys present a challenge for taxonomic identification, which could be overcome by high‐throughput imaging combined with machine learning for rapid classification of specimens. These procedures require that taxonomic labels from an existing source data set are used for model training and predictio...
MacArthur and Wilson's theory of island biogeography has been a foundation for obtaining testable predictions from models of community assembly and for developing models that integrate across scales and disciplines. Historically, however, these developments have focused on integration across ecological and macroevolutionary scales and on predicting...
Current understanding of ecological and evolutionary processes underlying island biodiversity is heavily shaped by empirical data from plants and birds, although arthropods comprise the overwhelming majority of known animal species, and as such can provide key insights into processes governing biodiversity. Novel high throughput sequencing (HTS) ap...
Landscape heterogeneity and the reconfiguration of host plant distributions as a consequence of Quaternary climate oscillations are suggested to play a determinant role in shaping the evolutionary history of herbivorous insects. The cactus moth, Cactoblastis cactorum, is a southern South American phytophagous insect specialized in the use of cacti...
Metazoan metabarcoding is emerging as an essential strategy for inventorying biodiversity, with diverse projects currently generating massive quantities of community-level data. The potential for integrating across such data sets offers new opportunities to better understand biodiversity and how it might respond to global change. However, large-sca...
Our current understanding of ecological and evolutionary processes underlying island biodiversity is heavily shaped by empirical data from plants and birds, although arthropods comprise the overwhelming majority of known animal species. This is due to inherent problems with obtaining high-quality arthropod data. Novel high throughput sequencing app...

Complex bulk samples of invertebrates from biodiversity surveys present a great challenge for taxonomic identification, especially if obtained from unexplored ecosystems. High-throughput imaging combined with machine learning for rapid classification could overcome this bottleneck. Developing such procedures requires that taxonomic labels from an e...
Aim
Although thermophilous and arid-dwelling relict biotas constitute a singular component of European biodiversity of high conservation value, we still largely ignore their biogeographic history. In this study, we investigate the geographical diversification of the Maghrebian-Levantine crested grasshopper and its colonization of semiarid habitats...
Although the genetic consequences of contemporary landscape composition and range shifts driven Pleistocene climatic oscillations have been studied fairly well in alpine organisms, we know much less about how these factors have shaped the demography of taxa with broader climatic niches and distributions. Here, we use high-throughput sequencing data...
Metabarcoding of DNA extracted from community samples of whole organisms (whole organism community DNA, wocDNA) is increasingly being applied to terrestrial, marine and freshwater metazoan communities to provide rapid, accurate and high resolution data for novel molecular ecology research. The growth of this field has been accompanied by considerab...
Genetic exchange between independently evolving lineages may give rise to the formation of new taxa, and hypotheses for this have been derived from species with intermediate phenotypes, when compared to potential parental species. Goulet-Scott and collaborators (2021) evaluate such a hypothesis in a wildflower species complex by integrating genomic...

Although the pervasiveness of intraspecific wing-size polymorphism and transitions to flightlessness have long captivated biologists, the demographic outcomes of shifts in dispersal ability are not yet well understood and have been seldom studied at early stages of diversification. Here, we use genomic data to infer the consequences of dispersal-re...
High‐throughput sequencing (HTS) is increasingly being used for the characterisation and monitoring of biodiversity. If applied in a structured way, across broad geographic scales, it offers the potential for a much deeper understanding of global biodiversity through the integration of massive quantities of molecular inventory data generated indepe...
Sur la carte de notre précédent travail (DEFAUT & NOGUERALES, 2019, page 16) c'est Gomphocerippus binotatus binotatus qui est indiqué dans les pré-Pyrénées ibériques. En y regardant de plus près, les données sont contradictoires : dans le Haut-Urgel (Montan de Tost, Gavarra) est présent un taxon aussi microptère que G. saulcyi saulcyi (un ♂ et quat...
Biodiversity genomics is a new and fast-growing discipline that uses large-scale DNA data to study species diversity and the processes that generate and maintain this diversity. Genomic technologies have enormous potential for establishing efficient biodiversity monitoring of island communities, in an effort to mitigate the impacts of global change...
Abstract. This study is based on previous works from the authors (DEFAUT 2011 et 2015, NOGUERALES 2017, NOGUERALES & al. 2016, 2017, 2018a, 2018b), which are complemented here by an additional biometric study considering 46 primary parameters (com-pared to 43 in DEFAUT 2001) quantified in 151 ♂♂ (62 ♂♂ in DEFAUT 2011), and 42 primary parameters (36...
Los efectos del fuego sobre la fauna terrestre son devastadores. Pero algunas especies pueden verse beneficiadas. Una de ellas es la alondra ricotí, amante de las parameras y del matorral ralo, una estructura vegetal que antaño se encargaba de mantener a raya el ganado extensivo.
There are examples of coexisting species with similar morphology and
ecology, in apparent contradiction to competition theory. Shrews
(Soricidae) are a paradigmatic example of this because members of this
group exhibit a conserved body form, relatively low variability in lifestyle
and, in many cases, a sympatric distribution. Here, we combined
geom...
Semi-natural open habitats have drastically changed in the last few decades due to agricultural intensification and rural depopulation. Steppe-birds, and especially those adapted to primary stages of vegetation succession, are threatened by an increase in scrub cover, and management actions are being applied to reverse scrub encroachment and restor...
Introgressive hybridization can introduce genetic novelty into recipient lineages, induce important phenotypic changes and, ultimately, result in the formation of new species. The conditions in which hybridization is more prone to occur and its potential evolutionary consequences have been long discussed, nevertheless empirical examples revealing i...
Quaternary climatic oscillations have been recognized as a major factor shaping the distribution and demography of most organisms worldwide. A classical paradigm establishes that populations that have persisted in climatically stable areas harbor higher genetic variation than those located in climatically unstable and/or recently colonized regions....
Background: The combination of model-based comparative techniques, disparity analyses and ecomorphological correlations constitutes a powerful method to gain insight into the evolutionary mechanisms that shape morphological variation and speciation processes. In this study, we used a time-calibrated phylogeny of 70 Iberian species of short-horned g...
The study of the neutral and/or selective processes driving genetic variation in natural populations is central to determine the evolutionary history of species and lineages and understand how they interact with different historical and contemporary components of landscape heterogeneity. Here, we combine nuclear and mitochondrial data to study the...
Understanding the consequences of past environmental changes on the abiotic and biotic components of the landscape and deciphering their impacts on the demographic trajectories of species is a major issue in evolutionary biogeography. In this study, we combine nuclear and mitochondrial genetic data to study the phylogeographical structure and linea...
Sexual size dimorphism (SSD) is widespread and variable in nature. Although female-biased SSD predominates among insects, the proximate ecological and evolutionary factors promoting this phenomenon remain largely unstudied. Here, we employ modern phylogenetic comparative methods on 8 subfamilies of Iberian grasshoppers (85 species) to examine the v...

Understanding the processes underlying spatial patterns of genetic diversity and structure of natural populations is a central topic in evolutionary biogeography. In this study, we combine data on ancient and contemporary landscape composition to get a comprehensive view of the factors shaping genetic variation across the populations of the scrub-l...
The integration of genetic information with ecological and phenotypic data constitutes an effective approach to gain insight into the mechanisms determining interpopulation variability and the evolutionary processes underlying local adaptation and incipient speciation. Here, we use the Pyrenean Morales grasshopper (Chorthippus saulcyi moralesi) as...
Background
Understanding the underlying processes shaping spatial patterns of genetic structure in free-ranging organisms is a central topic in evolutionary biology. Here, we aim to disentangle the relative importance of neutral (i.e. genetic drift) and local adaptation (i.e. ecological divergence) processes in the evolution of spatial genetic stru...
Understanding the factors promoting species formation is a major task in evolutionary research. Here, we employ an integrative approach to study the evolutionary history of the Californian scrub white oak species complex (genus Quercus). To infer the relative importance of geographical isolation and ecological divergence in driving the speciation p...
Conservation plans can be greatly improved when information on the evolutionary and demographic consequences of habitat fragmentation is available for several co-distributed species. Here, we study spatial patterns of phenotypic and genetic variation among five grasshopper species that are co-distributed across a network of microreserves but show r...
Anthropogenic habitat fragmentation has altered the distribution and population sizes in many organisms worldwide. For this reason, understanding the demographic and genetic consequences of this process is necessary to predict the fate of populations and establish management practices aimed to ensure their viability. In this study, we analyse wheth...
The Chorthippus group binotatus (Orthoptera: Acridae) is a species complex of grasshoppers distributed in southwest Europe and north Africa. They often form small
and fragmented populations due to human-driven habitat destruction and/or the patchy
distribution of their natural montane habitats. Here, we describe 18 novel polymorphic
microsatellite...
Patterns of small mammal habitat selection vary according to scale, although there are discrepancies about the importance of macro and micro-scale factors in rodent community assembly. We assess whether differences in their micro and macrohabitat selection patterns explain the coexistence of two sympatric rodents, Mus spretus and Apodemus sylvaticu...
We describe 12 polymorphic microsatellite markers for Ramburiella hispanica (Orthoptera: Acrididae), a specialist Mediterranean grasshopper that often forms highly fragmented populations due to extensive clearing of natural vegetation for agriculture. Polymorphism at these loci was evaluated in 20 individuals from La Mancha region, Central Spain. T...
In Europe, Dupont’s Lark Chersophilus duponti is a threatened open-habitat bird. Prescribed burning has sometimes been proposed for its conservation, but without evidence of its effectiveness. To evaluate the short-term effects of a summer wildfire on this species, we performed several transect counts in the burnt and unburnt parts of a shrubsteppe...
A wintering waterbird community in an artificial wetland: Laguna de Meco The progressive loss of natural wetlands throughout Europe has led to the use of human infrastructures such as gravel pits, irrigation ponds and reservoirs by waterbirds as an alterna-tive habitat. In Central Spain, the presence of man-made wetlands is essential for waterfowl...
The progressive loss of natural wetlands throughout Europe has led to the use of human infrastructures such as gravel pits, irrigation ponds and reservoirs by waterbirds as an alternative habitat. In Central Spain, the presence of man-made wetlands is essential for waterfowl conservation. The temporal dynamics of the wintering waterbird community w...
