Temporal Dynamics of Species Richness and Composition in a Peri-Urban Tropical Frog Community in Central Brazil. [PDF]

Ecol Evol
This study address how species coexistence and species–environment relationship are impacted by temporal variation in climate sub‐urban area. ABSTRACT Analyzing the temporal dynamics of ecological communities can shed light on coexistence mechanisms and help understand how populations and communities will behave in the face of climate change.

Taste for pollen comes in different shapes: Consumption by tadpoles from three divergent ecomorphotypes

Journal of Zoology, Volume 320, Issue 1, Page 42-52, May 2023., 2023
We studied pollen consumption and breakage of pollen grains by tadpoles of three different ecomorphotypes likely to influence ease of access to different feeding microhabitats. We found tadpoles adapted to feed on the water surface (where pollen is first available to aquatic food webs) to eat more pollen and break relatively more grains, which is ...

First national assessment of wildlife mortality in Ecuador: An effort from citizens and academia to collect roadkill data at country scale

Ecology and Evolution, Volume 13, Issue 3, March 2023., 2023
The first national assessment of wildlife mortality caused by road traffic in Ecuador. A comprehensive roadkill dataset with more than 5000 roadkill records in Ecuador that includes threatened and poorly known species. A joint effort of citizens and academia to collect roadkill data at a country scale.

Static allometries do not reflect evolutionary allometry in exaggerated weaponry of male New Zealand sheetweb spiders (Cambridgea spp.)

Journal of Evolutionary Biology, Volume 35, Issue 11, Page 1524-1536, November 2022., 2022
Weapons used in intrasexual competition frequently scale disproportionately with body size with large individuals developing disproportionately large traits (known as ‘positive static allometry’). This scaling relationship is heritable and, in New Zealand sheetweb spiders (Cambridgea spp.), we found that male chelicerae almost uniformly exhibit ...

Tourism may threaten wildlife disease refugia

Conservation Letters, Volume 15, Issue 4, July/August 2022., 2022
Abstract The remoteness and isolation of South American tabletop mountain (tepui) summits may protect against infections that underpin global amphibian declines. Increases in recreational pressure in such unspoiled destinations, and in isolated ecosystems globally, pose a poorly understood risk of wildlife disease introduction, especially in supposedly

Genetic analysis reveals candidate species in the Scinax catharinae clade (Amphibia: Anura) from Central Brazil

Genetics and Molecular Biology, 2016
Scinax (Anura: Hylidae) is a species-rich genus of amphibians (113 spp.), divided into five species groups by morphological features. Cladistic analyses however revealed only two monophyletic clades in these groups: Scinax catharinae and Scinax ruber ...

Influence of conspecifics and road noise on the properties of the advertisement call of Phyllodytes luteolus (Anura, Hylidae). [PDF]

Ecol Evol
In this work, we investigated the influence of motor vehicle noise on a highway in the municipality of Ilhéus on the acoustic parameters of the advertisement call of a species of anuran with bromeligenous habits. This was the first study to investigate this effect on a species that spends its entire life in bromeliads and to present data/values of its ...
