Developmental instability and phenotypic evolution in a small and isolated bear population

Anna Loy, Paolo Ciucci, Giulia Guidarelli, Erika Roccotelli & Paolo Colangelo
We explored fluctuating asymmetry (FA) and morphological integration (MI) in the skull of the small, highly inbred and divergent Apennine bear (Ursus arctos marsicanus), to explore its uniqueness and investigate any potential effects of inbreeding depression. We used 3d geometric morphometrics contrasting 17 Apennine bears with other two large outbred bear populations (22 from Scandinavia and 9 from Kamchatka) as controls. Shape divergence and variability were explored by a PCA on aligned coordinates of 39...

Mammal population densities at a global scale are higher in human-modified areas

Marlee A. Tucker, Luca Santini, Chris Carbone & Thomas Mueller
Global landscapes are changing due to human activities with consequences for both biodiversity and ecosystems. For single species, terrestrial mammal population densities have shown mixed responses to human pressure, with both increasing and decreasing densities reported in the literature. How the impacts of human activities on mammal populations translates into altered global density patterns remains unclear. Here we aim to disentangle the effect of human impacts on large-scale patterns of mammal population densities using a...

Towards a taxonomically unbiased EU Biodiversity Strategy for 2030

Stefano Mammola, Nicoletta Riccardi, Vincent Prié, Ricardo Correia, Pedro Cardoso, Manuel Lopes-Lima & Ronaldo Sousa
Through the Habitats Directive (92/43/EEC) and the LIFE projects financial investments, Europe has been the world’s experimental arena for biological conservation. With an estimated budget of €20 billion/year, the EU Biodiversity Strategy for 2030 has set an ambitious goal of reaching 30% Protected Areas and ensure no deterioration in conservation trends and status of all protected species. We analyzed LIFE projects focused on animals from 1992 to 2018 and we found that investment towards vertebrates...

Data from: Fine-scale spatial genetic structure across the species range reflects recent colonization of high elevation habitats in silver fir (Abies alba Mill.)

Enikő I. Major, Mária Höhn, Camilla Avanzi, Bruno Fady, Katrin Heer, Lars Opgenoorth, Andrea Piotti, Flaviu Popescu, Dragos Postolache, Giovanni G. Vendramin & Katalin Csilléry
Variation in genetic diversity across species ranges has long been recognized as highly informative for assessing populations’ resilience and adaptive potential. The spatial distribution of genetic diversity within populations, referred to as fine-scale spatial genetic structure (FSGS), also carries information about recent demographic changes, yet it has rarely been connected to range scale processes. We studied eight silver fir (Abies alba Mill.) population pairs (sites), growing at high and low elevations, representative of the main...

Data from: Adaptation to hand-tapping affects sensory processing of numerosity directly: evidence from reaction times and confidence

Paula A. Maldonado Moscoso, Guido Marco Cicchini, Roberto Arrighi & David C. Burr
Like most perceptual attributes, the perception of numerosity is susceptible to adaptation, both to prolonged viewing of spatial arrays and to repeated motor actions such as hand-tapping. However, the possibility has been raised that adaptation may reflect response biases rather than modification of sensory processing. To disentangle these two possibilities, we studied visual and motor adaptation of numerosity perception while measuring confidence and reaction-times. Both sensory and motor adaptation robustly distorted numerosity estimates, and these...

Life-history responses of a freshwater rotifer to copper pollution

Federica R. Schanz, Stefan Sommer, Andrea Lami, Diego Fontaneto & Arpat Ozgul
In organisms with dormant stages, life-history responses to past pollution can be studied retrospectively. Here, we study such responses in a rotifer (Brachionus calyciflorus) from the once heavily copper-polluted Lake Orta (Italy). We extracted resting eggs from sediments, established clonal lineages from hatchlings, and exposed newborns of these lineages to one of three copper concentrations that each mimicked a specific period in the lake’s pollution history. For each rotifer, we daily collected life-table data. We...
