BEHAVIORAL THERMAL TOLERANCE OF AMPHIBIANS AND REPTILES OF THE BRAZILIAN SHIELD

Principal investigators: Juan C. Díaz-Ricaurte 


Ectothermic animals are tightly dependent on suitable temperature conditions to optimize multiple physiological functions like moving and feeding. Several reptile species use behaviour to thermoregulate when temperatures fall outside their preferred range. However, given the increase in global temperatures, the ability of these organisms to remain within these limits may be compromised, potentially causing local extinctions and changes in their distribution. In this project we want to understand how behavioral thermal limits are related to the evolutionary history of Neotropical amphibians and reptiles.

INTERACTION OF THERMAL TOLERANCE AND CURRENT AND FUTURE GEOGRAPHIC DISTRIBUTION OF SOUTH AMERICAN SNAKES (CROTALINAE: BOTHROPS AND BOTHROCOPHIAS): A PREDICTION OF THE RESPONSE OF THESE ORGANISMS TO CLIMATE CHANGE

Principal investigator: Juan C. Díaz-Ricaurte

The objective of this project will be to assess the relationship of the behavioral thermal tolerance with current distribution patterns of species of Bothrops and Bothrocopias from South America.

EFFECTS OF HABITAT DISTURBANCE ON COMMUNITIES OF AMPHIBIANS AND SQUAMATE REPTILES: SUBSIDIES FOR MANAGEMENT PROGRAMS, SPECIES CONSERVATION ASSESSMENTS AND CONSERVATION ACTION PLANS

Principal investigator: Marcio Martins

This study has two main objectives: (1) assess the effects of prescribed fires on the species, functional and phylogenetic diversity of frog and lizard communities, as a way to provide subsidies for the conservation of species and fire management in protected areas; and (2) assess the effects of the substitution of native forests by tree plantations on the species, functional and phylogenetic diversity of snake and frog communities, as a way to provide subsidies for the conservation of species and the management of landscapes in which native forests and tree plantations predominate. The knowledge resulting from this project will subsidize the assessment of the conservation status of the studied amphibians and squamate reptiles and

the definition of conservation actions.

POPULATION ECOLOGY AND NATURAL HISTORY OF TWO AMAZONIAN POISON FROGS IN COLOMBIA.

Principal Investigator: Yulfreiler Garavito-David

This project aims to evaluate the population ecology and document aspects of the natural history of two Amazonian poison frogs in Colombia. In order to accomplish this, we intend to: (1) Estimate the population size, habitat use, and territoriality of Ameerega hahneli and A. ingeri in two relictual forests and (2) document aspects of the natural history of both species, such as activity patterns, and reproductive behaviour (e.g. amplexus, characteristics of calling and oviposition sites, and characteristics of egg clutches).

EFFECTS OF HABITAT USE ON AMPHIBIAN AND REPTILE DIVERSITY IN THE COLOMBIAN AMAZON

Principal Investigator: Juan C. Díaz-Ricaurte

This study provides useful information for understanding the structure of amphibians and reptiles assemblages of the Colombian Amazon and is potentially useful for conservation assessments and for designing conservation plans.
