Sensitivity of the frog model to initial conditions
(Univ Washington, 2019-11)
The frog model is an interacting particle system on a graph. Active particles perform independent simple random walks, while sleeping particles remain inert until visited by an active particle. Some number of sleeping ...
Differences in escape behavior between a cryptic and an aposematic litter frog
(2011)
Clay models have been used to investigate the relative antipredator effectiveness of cryptic and of aposematic coloration in litter frogs, but such studies do not account for possible differences in prey escape behavior. ...
An experimental assessment of landscape configuration effects on frog and toad abundance and diversity in tropical agro-savannah landscapes of southeastern Brazil
(Springer, 2012-01-01)
Amphibians are an imperiled group of vertebrate animals that typically have biphasic life histories involving a shift from aquatic larval habitats to terrestrial adult habitats. Habitat loss is the greatest threat to ...
A connection between a system of random walks and rumor transmission
(Elsevier Science BvAmsterdamHolanda, 2013)
Effects of future climate change and habitat loss in the distribution of frog species in the Ecuadorian Andes
(PUCE, 2015)
The biodiversity of the tropical Andes is threatened by climate change and habitat loss. Many studies have focused in the future effects of climate change on species distribution and conservation but few have included the ...
Micelle bound structure and model membrane interaction studies of the peptide Hylin a1 from the arboreal south American frog Hypsiboas albopunctatus
(2015-07-01)
Antimicrobial peptides (AMPs) appear as a promising therapeutic candidate against multiresistant pathogens, because they are able to kill microorganisms and have low toxicity of resistance cells. Hylin a1 (Hy-a1, ...
Can differences between continental and insular habitats influence the parasites communities associated with the endemic frog Haddadus binotatus ?
(2020-01-01)
Habitats characterized by geographic isolation such as islands have been studied using different organisms as models for understanding the dynamic and insular patterns of biodiversity. Determinants of parasite richness in ...
Colouration in amphibians as a reflection of nutritional status: The case of tree frogs in Costa Rica
(2017-08-24)
Colouration has been considered a cue for mating success in many species; ornaments in males often are related to carotenoid mobilization towards feathers and/or skin and can signal general health and nutrition status. ...
Spatio-temporal patterns of foraging and feeding behavior of Elachistocleis bicolor (Anura: Microhylidae)
(Instituto de Ciencias Naturales, 2017-12)
We analyzed spatio-temporal patterns and behavior of the foraging activity of the myrmecophagous frog Elachistocleis bicolor. We delimit ten 1m2 plots and recorded the number of frogs, distance between individuals and ...
Spatio-temporal patterns and ethology of Elachistocleis bicolor (anura: microhylidae) foraging activity
(Instituto de Ciencias Naturales, 2017-03)
We analyzed spatio-temporal patterns and behavior of the foraging activity of the myrmecophagous frog Elachistocleis bicolor. We delimit ten 1m2 plots and recorded the number of frogs, distance between individuals and ...
