How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Exotic organisms have traits that allow them to effectively disperse and propagate into novel environments. The ability to adapt to new environments has enabled the cane toad (Rhinella marina) to successfully invade novel ecosystems. Their leg length correlates with dispersal success and is selected for in invading populations. Given their successf...
The Amazonian poison frog genus Ameerega is one of the largest yet most understudied of the brightly colored genera in the anuran family Dendrobatidae, with 30 described species ranging throughout tropical South America. Phylogenetic analyses of Ameerega are highly discordant, lacking consistency due to variation in data types and methods, and ofte...
To date, half (16 of 32) of the species of Ameerega have had their tadpoles described: A. altamazonica, A. bassleri, A. bilinguis, A. braccata, A. cainarachi, A. flavopicta, A. hahneli, A. macero, A. parvula, A. petersi, A. picta, A. rubriventris, A shihuemoy. A. silverstonei, A. smaragdina, and A. trivittata (Lescure, 1976; Silverstone, 1976; Duel...
The Tropical Andes contains exceptionally high diversity, much of it arising within the Quaternary period. The complex geology of the Andes and paleoclimate fluctuations within the Quaternary suggest complex speciation scenarios. This, in turn, has contributed to idiosyncratic speciation modes among shallowly diverged Amazonian taxa. Many relations...
The ecological multifunctionality of colour often results in multiple selective pressures operating on a single trait. Most research on colour evolution focuses on males because they are the most conspicuous sex in most species. This bias can limit inferences about the ecological drivers of colour evolution. For example, little is known about popul...
Dataset of colour measurements, geographic information, time, and reproductive state. This is the total dataset, including field number, lake designation, raw RGB brightness levels, lake surface area in hectares, watershed designation, date (in month/day format), and gravidity designation, where 1 is gravid, and 0 is not gravid.
SDMtoolbox 2.0 is a software package for spatial studies of ecology, evolution, and genetics. The release of SDMtoolbox 2.0 allows researchers to use the most current ArcGIS software and MaxEnt software, and reduces the amount of time that would be spent developing common solutions. The central aim of this software is to automate complicated and re...
