Data from: Games academics play and their consequences: how authorship, h-index, and journal impact factors are shaping the future of academia

Jan Gogarten, Colin Chapman, Julio Bicca-Marques, Sébastien Calvignac-Spencer, Pengfei Fan, Peter Fashing, Songtao Guo, Claire Hemingway, Fabian Leendertz, Baoguo Li, Ikki Matsuda, Rong Hou, Juan Carlos Serio-Silva & Nils Chr. Stenseth
Research is a highly competitive profession where evaluation plays a central role; journals are ranked and individuals are evaluated based on their publication number, the number of times they are cited, and their h-index. Yet, such evaluations are often done in inappropriate ways that are damaging to individual careers, particularly for young scholars, and to the profession. Furthermore, as with all indices, people can play games to better their scores. This has resulted in the...

Data from: Crop feeding by brown howlers (Alouatta guariba clamitans) in forest fragments: the conservation value of cultivated species

Óscar M. Chaves & Júlio César Bicca-Marques
Primates inhabiting human-modified habitats often complement their diets with cultivated species. Although this flexible foraging behavior reduces feeding stress in animals inhabiting small or low-quality habitats, its potential economic costs may promote negative human–nonhuman primate interactions. It is critical to assess the importance of cultivated species to primate diets, the factors influencing their exploitation, and their associated economic costs to evaluate the conservation value of cultivated species and the impact of crop feeding on human–nonhuman...

Data from: Quantity and quality of seed dispersal by a large arboreal frugivore in small and large Atlantic forest fragments

Óscar M. Chaves, Júlio César Bicca-Marques & Colin A. Chapman
Seed dispersal is a key process driving the structure, composition, and regeneration of tropical forests. Larger frugivores play a crucial role in community structuring by dispersing large seeds not dispersed by smaller frugivores. We assessed the hypothesis that brown howler monkeys (Alouatta guariba clamitans) provide seed dispersal services for a wide assemblage of plant species in both small and large Atlantic forest fragments. Although fruit availability often decreases in small fragments compared with large ones,...

Mechanisms for color convergence in a mimetic radiation of poison frogs

Evan Twomey, Morgan Kain, Myriam Claeys, Kyle Summers, Santiago Castroviejo-Fisher & Ines Van Bocxlaer
In animals, bright colors often evolve to mimic other species when a resemblance is selectively favored. Understanding the proximate mechanisms underlying such color mimicry can give insights into how mimicry evolves, for example, whether color convergence evolves from a shared set of mechanisms or through the evolution of novel color production mechanisms. We studied color production mechanisms in poison frogs (Dendrobatidae), focusing on the mimicry complex of Ranitomeya imitator. Using reflectance spectrometry, skin pigment analysis,...
