• Tourism activity affects the cave's physical environment in several ways, such as damaging speleothems, altering the cave structure for ease of access, and the shifting of cave microclimate. Nevertheless, it is less clear how the pressure of touristic activities affects the cave fauna.
• This study aimed to investigate the effects from tourism ac...

Several studies have tried to elucidate the main environmental features driving invertebrate community structure in cave environments. They found that many factors influence the community structure, but rarely focused on how substrate types and heterogeneity might shape these communities. Therefore, the objective of this study was to assess which s...
A phylogenetic morphological analysis of the genus Ogyges Kaup, distributed in Nuclear Central America, from Chiapas, Mexico, to northwestern Nicaragua was undertaken. Five species of Proculejus Kaup, distributed north of the Isthmus of Tehuantepec in Mexico, were selected as outgroup. Ogyges was recovered as monophyletic with three species groups:...

The Chupacabras is an animal that was recently added to the pages of cryptozoology as part of a suburban legend. It´s origin dates from 1995 in the rural regions of Puerto Rico. Impelled by the sensationalist media, the legend extended all the way to the United States and then to the rest of America. However, there are some anecdotal records of sev...
Under controlled laboratory conditions, at 26 o C 75% relative humidity and a light/darkness cycle of 12/12 hours, the life cycle of the green bottle fly Phaenicia eximia (Wiedemann) was studied. The estimated average time from oviposition to the emergence of adults was 306 h (an average of almost 13 days). The eggs stadium is 19 h (0.8 d), the lar...

This represents the second species of the genus for Guatemala, differing from the closely related Mexican species Oileus rimator (Truqui) in having a straight anterior clypeal border, the postocular sulcus div...
A rapid biodiversity assessment was carried out in the Sierra Chinajá, Guatemala in order to support the conservation policies of the national agency for protected areas management. This study represents the first systematic account of the flora and fauna of the area. The floristic composition was surveyed using 21 Whitaker plots and non-systematic...

Escenarios de tierra de baja ele...
SUBFAMILY PASSALINAE LEACH 1815 TRIBE PASSALINI LEACH 1815 This Pantropical tribe includes six genera (five described) in the New World.

We linked primary dispersal by spider monkeys (Ateles geoffroyi) and howler monkeys (Alouatta pigra) to post-dispersal seed fate by studying the effects of dung type and defecation pattern on secondary seed dispersal by dung beetles. First, we described the defecation patterns for both primate species. Howler monkeys generally defecated in groups (...
The following nomenclatural changes in passalid taxonomy are made: Veturius laevior (Kaup 1868) n. stat., bonasp.; V. lineatosulcatus Luederwaldt 1941, n. syn. of V. laevior; Ogyges championi (Bates 1886) n. stat., bona sp.; and O. laevior (Kaup 1868) sensu auct., n. syn.of O. championi. New distribution records are given for V. sinuatocollis Kuwer...
Biological diversity conservation within natural reserves has been prioritized, but conservation efforts outside protected areas (where most human activities take place) have been very little considered. In this scenario, an alternative agricultural practice that may reduce the impacts of fragmentation in outer landscapes is a perforation process,...
Two new species of Copris Geoffroy from Guatemala and Honduras are described and illustrated: Copris caliginosus sp. nov. and Copris nubilosus sp. nov.

Los Passalidae, por varias razones, son buenos organismos indicadores de endemismo. Encontramos 66 especies de Passalidae en 32 bosques nubosos de Guatemala. Para priorizar la conservación de estos bosques, establecimos un método que evalúa riqueza de especies, endemismo y similitud entre ensambles de pasálidos y el grado de protección de los bosqu...
Experimental work has established that vertebrates can have a large impact on the abundance of arthropods in temperate forest and grasslands, as well as on tropical islands. The importance of vertebrate insectivory has only rarely been evaluated for main- land tropical ecosystems. In this study, we used exclosures to measure the impact of birds on...
La geoestadística es una rama de la estadística aplicada con la que es posible modelar estructuras espaciales a partir del análisis de la dependencia espacial que pueda existir o no, entre los diferentes valores que una variable de interés pueda tomar. Se utilizó geoestadística en el análisis del patrón espacial de especies de escarabajos copronecr...

The apparent rarity (four specimens known) of Deltochilum valgum acropyge Bates is due to a collecting artifact. Captures of 10 adult specimens in the Mayan Biosphere Reserve, Peten, Guatemala, in traps baited with live millipedes (Diplopoda: Spirobolida), suggest that it is a specialist in millipede predation, of nocturnal habits and has wide geog...
