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...

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...

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...

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.

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...

... taeniatus. A third species, T. nigroluteus, has been suggested to be distributed in the Pacific coast of Colombia (Barquero & Arguedas, 2019), based on a review of available information in scientific collection databases. Nevertheless, the occurrence of this species in Colombia is still surrounded with doubts, since older records from Alarcón-Pardo (1978) for the Atlantic coast correspond to a misidentification, and Barquero & Arguedas, 2019 did not provide detailed information about the record they reported, neither reviewed the specimen. ...
... Ornamental aquaculture involves keeping and breeding marine, brackish, and freshwater organisms for trade or hobby (i.e., algae, plants, invertebrates, fishes, amphibians, and reptiles), primarily for an aesthetic goal Tlusty et al., 2013). The aquarium trade is a multi-billion US$ industry that has grown in economic and social importance and has engaged many enthusiasts worldwide over decades (Maceda-Veiga et al., 2016;Allen et al., 2017;Livengood and Chapman, 2007). Most taxa in the trade originated from the tropics, where people in rural communities collect species to be distributed in Europe, Australia, Asia and North America (Akmal et al., 2020;Evers et al., 2019;Maceda-Veiga et al., 2016;Nobile et al., 2019;Patoka et al., 2015a;Whittington and Chong, 2007). ...
... Studies on ecomorphology in mainland Anolis show that leg length, body shape, width and head length can be correlated mostly with perch heightbut this correlation may vary depending on the species, population, and life stage studied (Irschick, et al., 2005;Barquero, 2008) and that factors such as predation and intraspecific and interspecific competition may lead to unspecific use of microhabitat type (Pounds, 1988;Barquero, 2008;Feiner et al., 2021). In this regard, it has been observed that when several Anolis species coexist in the same locality, the larger and more dominant species can displace the smaller or less dominant species, forcing them to use a reduced number of microhabitats (Barquero and Arguedas, 2009;Losos, 2009;Yuan et al., 2021), which in most cases are sub-optimal (e.g., sites with lower environmental temperature or inadequate perches; Henderson and Fitch, 1975); in addition, these sub-optimal ecological spaces are already occupied by other species of the same or different genus (Feiner et al., 2021). On the other hand, if these smaller or less dominant species live in isopatry, they can exploit a greater number of microhabitats (Barquero, 2008;Logan et al., 2014;Logan et al., 2016). ...
