The illegal trade has been threatening tortoise populations worldwide for decades. Nowadays, however, DNA typing and forensic genetic approaches allow us to investigate the geographic origin of confiscated animals and to relocate them into the wild, providing that suitable molecular tools and reference data are available. Here we assess the suitability of a small panel of microsatellite markers to investigate patterns of illegal translocations and to assist forensic genetic applications in the endangered Mediterranean land...

Data from: A novel landscape genetics approach demonstrates the effects of human disturbance on the Udzungwa red colobus monkey (Procolobus gordonorum)

Maria Jose Ruiz-Lopez, Claudia Barelli, Francesco Rovero, Keith Hodges, Christian Roos, William E. Peterman & Nelson Ting
A comprehensive understanding of how human disturbance affects tropical forest ecosystems is critical for the mitigation of future losses in global biodiversity. Although many genetic studies of tropical forest fragmentation have been conducted to provide insight into this issue, relatively few have incorporated landscape data to explicitly test the effects of human disturbance on genetic differentiation among populations. In this study, we use a newly developed landscape genetic approach that relies on a genetic algorithm...

Data from: No ecological opportunity signal on a continental scale? Diversification and life-history evolution of African true toads (Anura: Bufonidae)

H. Christoph Liedtke, Hendrik Müller, Mark-Oliver Rödel, Michele Menegon, LeGrand Nono Gonwouo, Michael F. Barej, Václav Gvoždík, Andreas Schmitz, Alan Channing, Peter Nagel & Simon P. Loader
The niche-filling process predicted by the “ecological opportunity” (EO) model is an often-invoked mechanism for generating exceptional diversity in island colonizers. Whether the same process governs lineage accumulation and trait disparity during continental colonization events is less clear. Here, we test this prediction by investigating the rate dynamics and trait evolution of one of Africa's most widespread amphibian colonizers, the true toads (Bufonidae). By reconstructing the most complete molecular phylogeny of African Bufonidae to date,...

Data from: Phylogenetic stability, tree shape, and character compatibility: a case study using early tetrapods

Massimo Bernardi, Kenneth D. Angielczyk, Jonathan S. Mitchell & Marcello Ruta
Phylogenetic tree shape varies as the evolutionary processes affecting a clade change over time. In this study, we examined an empirical phylogeny of fossil tetrapods during several time intervals, and studied how temporal constraints manifested in patterns of tree imbalance and character change. The results indicate that the impact of temporal constraints on tree shape is minimal and highlights the stability through time of the reference tetrapod phylogeny. Unexpected values of imbalance for Mississippian and...

Data from: A standardized assessment of forest mammal communities reveals consistent functional composition and vulnerability across the tropics

Francesco Rovero, Jorge Ahumada, Patrick Jansen, Douglas Sheil, Patricia Alvarez, Kelly Boekee, Santiago Espinosa, Marcela Lima, Emanuel Martin, Timothy O’Brien, Julia Salvador, Fernanda Santos, Melissa Rosa, Alexander Zvoleff, Chris Sutherland & Simone Tenan
Understanding global diversity patterns has benefitted from a focus on functional traits and how they relate to variation in environmental conditions among assemblages. Distant communities in similar environments often share characteristics, and for tropical forest mammals, this functional trait convergence has been demonstrated at coarse scales (110-200 km resolution), but less is known about how these patterns manifest at fine scales, where local processes (e.g., habitat features and anthropogenic activities) and biotic interactions occur. Here,...

Potential sex-dependent effects of weather on apparent survival of a high-elevation specialist

Eliseo Strinella, Davide Scridel, Mattia Brambilla, Christian Schano & Fränzi Korner-Nievergelt
Mountain ecosystems are inhabited by highly specialised and endemic species which are particularly susceptible to climatic changes. However, the mechanisms by which climate change affects species population dynamics are still largely unknown, particularly for mountain birds. We investigated how weather variables correlate with apparent survival of the White-winged Snowfinch Montifringilla nivalis, a specialist of high-elevation habitat. We analysed a 15-year (2003-2017) mark-recapture data set of 671 individuals from the Apennines (Italy), using mark-recapture models. We...

Data from: Sexual selection on male vocal fundamental frequency in humans and other anthropoids

David A. Puts, Alexander K. Hill, Drew H. Bailey, Robert S. Walker, Drew Rendall, John R. Wheatley, Lisa L. M. Welling, Khytam Dawood, Rodrigo A. Cárdenas, Robert P. Burriss, Nina G. Jablonski, Mark D. Shriver, Daniel J. Weiss, Adriano R. Lameira, Coren L. Apicella, Michael J. Owren, Claudia Barelli, Mary E. Glenn & Gabriel Ramos-Fernandez
In many primates, including humans, the vocalizations of males and females differ dramatically, with male vocalizations and vocal anatomy often seeming to exaggerate apparent body size. These traits may be favoured by sexual selection because low-frequency male vocalizations intimidate rivals and/or attract females, but this hypothesis has not been systematically tested across primates, nor is it clear why competitors and potential mates should attend to vocalization frequencies. Here we show across anthropoids that sexual dimorphism...

An objective-based prioritization approach to support trophic complexity through ecological restoration

1. Reassembling ecological communities and rebuilding habitats through active restoration treatments requires curating the selection of plant species to use in seeding and planting mixes. Ideally, these mixes should be assembled based on attributes that support ecosystem function and services, promote plant and animal species interactions and ecological networks in restoration while balancing project constraints. Despite these critical considerations, it is common for species mixes to be selected opportunistically. Reframing the selection of seed mixes...
