SOUNDS OF THE NORTHERN ANDES: THE CALLS OF A DIVERSE AND ENDANGERED FROG COMMUNITY (AMPHIBIA, ANURA) FROM ECUADOR

Sounds of the northern Andes: the calls of a diverse and endangered frog community (Amphibia, Anura) from Ecuador

The emission of calls is one of the most distinctive and important reproductive traits in anurans.Given the biological significance of vocalizations, this trait is also useful for identification proposes and is key in recognizing cryptic diversity.However, the majority of the calls from tropical ecosystems, especially in the high Andean mountains,

Assessing senescence patterns in populations of large mammals

Theoretical models such as those of Gompertz and Weibull are commonly used to study senescence in survival for humans and laboratory or captive animals.For wild populations of vertebrates, senescence in survival has more commonly been assessed by fitting simple linear or quadratic relationships between survival and age.By using appropriate constrai
