Introduction: Integrating genetic data into conservation management decisions is a challenging task that requires strong partnerships between researchers and managers. Conservation in Latin America is of crucial relevance worldwide given the high biodiversity levels and the presence of hotspots in this region. Methods: We conducted a survey across...

Objetivo: Conocer la distribución geográfica y estimar la composición de la dieta del Mochuelo de hoyo Athene cunicularia en el estado Falcón, Venezuela. Metodología: investigación descriptiva. Para determinar la dieta fueron monitoreadas 19 madrigueras en las que se colectaron 62 egagrópilas de 27 individuos, en distintos periodos, enero – abri...

The Paraguaná moustached bat, Pteronotus paraguanensis (Mormoopidae), is one of the four species of bats endemic to Venezuela. Besides having a geographic distribution restricted to the Paraguaná Peninsula, it is currently classified as Endangered in the IUCN Red List of Threatened Species. Changes in land use, frequent human disturbance at diurnal...

La IV Jornada Científico-Técnica y Comunitaria del Programa de Licenciatura en Ciencias Ambientales se llevó a cabo en la ciudad de Santa Ana de Coro, del 06 al 08 de julio de 2016, en el Módulo C, Complejo Académico Los Perozo de la Universidad Nacional Experimental “Francisco de Miranda”. En esta Jornada participa todo el Personal Docente y Admi...

Of the 3 species comprising the genus Leptonycteris Miller, L. curasoae has been the least studied with respect to its long-distance flights and potential for seasonal migrations. We studied long-distance movements between islands and between islands and the mainland in the Curaçaoan long-nosed bat. We used mark—recapture with periodic sampling and...

The main objective of this research was the chromosomal characterization of the sigmodontine rodent Calomys hummelincki (Husson, 1960), which belongs to the Tribe Phyllotini. The distribution of C. hummelincki is restricted to a region of northern South America, comprising Venezuela, Aruba, Curaçao and probably the Colombian llanos and Guajira Peni...

Current scientific capacities in Austral and Neotropical America (ANA) for plant conservation genetics (PGC) were assessed. Publications (1980–2010) were analyzed, considering the taxa and geographical origin of samples, geographical origin of the institutional affiliation of the authors (first, corresponding and co-authors), the threat category of...

Introduzione. Calomys é un genere di roditori sigmodontini che occupa habitat di prateria e savana del Sud America. Questo genere presenta 10 specie riconosciute tra le quali Calomys hummelincki, la cui distribuzione geografica é limitata al Venezuela, alla Colombia orientale e alle Antille Olandesi. Dati di filogenesi molecolare ottenuti da Salaza...

Aspects of the feeding ecology of Leptonycteris curasoae in Northern Venezuela were stitched through analysis of pollen collected from fur and feces. Cactaceae arid Bombacaceae (100%) were the most frequently found pollen in feces, followed by Caricaceae (66.7%) and Agavaceae (22.2%). No significant differences were found between the frequency of o...

The aim of the present study was to assess the degree of genetic variation and divergence among six populations of Calomys hummelincki, a phyllotine rodent distributed in northern South America. With this information we will try to evaluate the two hypotheses of possible colonization and differentiation of this group of rodents postulated by Baskin...

From September 1995 through December 1996, standardized, simultaneous monthly censuses of Caribbean Flamingos (Phoenicopterus ruber ruber) were conducted at 17 locations along the Venezuelan coast and several offshore islands. Maximum numbers of flamingos were observed in May 1996 (34,171) and December 1996 (33,085). Most flamingos (82.4%) were obs...

The level of genetic polymorphism was analyzed in a population sample of Calomys hummelincki from Venezuela. Enzymes and proteins studied by means of gel electrophoresis give information on 30 loci. The proportion of polymorphic loci was 40%, and mean expected heterozygosity (H(e)) was 12.7%. These values are higher than those reported for most spe...

To determine if there was a latitudinal effect on the reproductive and social pattern of Lepronycteris curasoae, a population from Northern Venezuela (Paraguana, Venezuela) was studied. Monthly sampling took place at Piedra Honda cave, from November 1991 to October 1993. A total of 1,590 individuals was captured with harp traps. Sex-ratio of the sa...

The Biological Reserve of Piedra Honda cave was created in 1988. It is located in Paraguana Peninsula (Falcón State, Venezuela). During a population dynamic study of Leptonycteris curasoae, additional information was obtained from other chiroptera species roosting at Piedra Honda Cave. The animals were captured monthly, during one year, with harp t...

Several authors have proposed that Oryzomys albigularis constitutes a supraspecific complex and that chromosomal pericentromeric inversions have played a fundamental role in the diversifying process. With the purpose of clarifying the unclear taxonomic situation of the nominal forms of O. albigularis living in Venezuela, a cytogenetic study was car...

Diet delection of Holochilus venezuelae was studied through its food habits in rice fields in Venezuela. Selectivity was assessed with the Vanderploeg and Scavia selectvity index and with correlation analysis between availability (%) and food ingested (%).H.venezuelae consumed 37% of the plant species present in the study area. Both methods indicat...

Some ecophysiological characteristics of the phyllotine rodent Calomys hummelincki under controlled laboratory conditions are described.

Abstraet: The food habits of Holochilus lIenezuelae. Oryzomys delicalus, Sigmodon alslani and Zygodontomys mi· crolÍll us were studied by storoaeh cootents anaIysis in aged Venezuelan rice-fie1ds. H. lIenezuelae is mainiy herbivo­ rous, feeding primarly on rice. The importance of other food items depends on their availability. S. alslani, is omnivo...
