Article
Costa Rican agriculture uses pesticides both extensively and intensively. Once biocides are released into the environment, they are also toxic to non-target vertebrates and invertebrates. Exposure of amphibians to pesticides can be lethal and affect their growth, development and behavior. β-endosulfan is a persistent organochlorine that has been de...
Article
Agalychnis annae is a species endemic to Costa Rica and Panama with populations shrinking or disappearing from several locations. We studied the reproduction of a relict population of A. annae in a 1,300 m2 natural pond in Costa Rica during 2007–2008. We marked adults with a visible implant alphanumeric tag injected in the thigh. We measured reprod...

The participation of citizens in science projects has been increasing over the past two decades and has proven to be of great importance for biological research, specially for obtaining essential biodiversity data. Citizen science participation can be greatly improved through information and communication technologies (ICT). Therefore, our aim is t...

Studies evaluating the health status and characteristics of free-ranging wildlife populations are scarce or absent for most species. Saurian health assessments are usually performed in species that have conservation issues or that are kept in captivity. The Berthold's bush anole (Polychrus guturossus) is one of eight species belonging to the genus...

Many aspects of the biology of various snake species remain unknown, and the extent of this lack of information is not always clear. As new research usually depends upon previous findings, the gaps in our knowledge and the accuracy of published information are of major importance. Therefore, an analysis of all available information on snakes of the...

The terciopelo (Bothrops asper) inhabits human-modified environments such as agricultural areas, becoming more prone to be exposed to organophosphate insecticides. These chemicals can inhibit plasmatic butyr-ylcholinesterases (BChE) activity in B. asper. Caribbean and Pacific populations of B. asper belong to two divergent lineages that exhibit rob...
Article
Ecologists have long been intrigued by which factors influence habitat use by an organism and how communities are structured. However, the links between habitat preferences, morphology, biotic interactions and community structure are still poorly understood. Moreover, interpopulation variation in ecomorphological relationships has usually been negl...
Article
The terciopelo (Bothrops asper), is one of the most important venomous snakes in Costa Rica and common on agriculture where insecticides are frequently used for pest control. To assess the exposure to organophosphates on captive B. asper, an experiment using chlorpyrifos and butyrylcholinesterase (BChE), as a biomarker was conducted. In addition to...

Muchos individuos de la especie Homo sapiens consideran estar separada del resto de criaturas del Reino Animal. Esto implica que hay un desligamiento de las relaciones entre el ser humano y el entorno natural, cuyas causas son variadas y sus consecuencias suelen ser nocivas. El presente ensayo repasa las características ecológicas del ser humano, c...

Random and non-random mating result from sexual selection, and both can occur across populations of the same species. Body size is a trait commonly used to determine if mating is random or non-random, and for the latter there are two possible outcomes: size-assortative mating and size-dependent mating. Females of the Túngara Frog (Engystomops putul...

Ornamental fish trade is a growing business around the world, but also a major pathway for the introduction of potentially invasive species. Trade patterns and policies have been evaluated in high-income countries while developing countries in tropical regions have been overlooked, even when they are especially vulnerable to invasions by aquarium f...
Data
Species list and number of live individuals of each species imported into Costa Rica between 1998 and 2004. The current taxonomic classification and habitat type (freshwater, marine or both) are also shown. Please consider using the following citation for this material: AllenPE, BarqueroMD, BermúdezE, CalderónJC, HiljeB, Pineda W, Saborío-Rodríguez...

La temperatura ambiental y los patrones de precipitacion han sufrido cambios signicativos durante las ultimas decadas. Estos cambios globales del clima han generado alteraciones en las caractersticas biologicas de los organismos. Aunque la mayora de estas modicaciones se han documentado para especies que habitan en zonas templadas, la flora y fauna...

Signal diversification is often the product of sexual and/or natural selection and may be accompanied by genetic differentiation or simply reflect a plastic response to social and environmental variables. We use an agamid lizard endemic to Australia, the Jacky dragon (Amphibolurus muricatus), to examine the relationships between population relatedn...
Article
Jacky dragons (Amphibolurusmuricatus) are ubiquitous in south-eastern Australia and were one of the first Australian reptiles to be formally described. Because they are so common, Jacky dragons are widely used as a model system for research in evolutionary biology and ecology. In addition, their distribution along the Great Dividing Range of easter...

Basic information about Nicaraguan herpetofauna is still unavailable, although this has begun to change in recent years. Environmental change has been fragmenting pristine habitats, threatening the survival of many species. The aim of this study is to analyze species composition in two isolated regions of Nicaragua. We report a list of amphibians a...

Lizards of the genus Anolis are commonly used as models for several ecological studies. Nevertheless, some aspects of their ecology have not been studied and information reported previously for several species must be reanalyzed. The aim of this study is to examine the structural habitat use in a population of the Many-scaled Anole, Anolis polylepi...

On 25 May 2002, we observed a House Wren (Troglodytes aedon) eating a juvenile house gecko (Hemidactylus frenatus) in Golfito, Costa Rica. Just a few studies report insect-eating birds taking vertebrate prey, and we found no prior publications for this species. The recently introduced house gecko may be a new potential food resource for other nativ...

RESUMEN: El tepezcuintle o paca (Agouti paca) es una especie que ha sufrido una intensa cacería en todo su ámbito de distribución, por lo que han surgido esfuerzos para la producción de animales en cautiverio como medio para reducir esta presión. Sin embargo, aún se desconocen aspectos básicos sobre la cría en cautiverio de esta especie y otros son...
