Data from: Individual variation in male reproductive behaviour is linked to temporal heterogeneity in predation risk

Miguel Barbosa, Amy E. Deacon, Maria Joao Janeiro, Indar Ramnarine, Michael Blair Morrissey & Anne E. Magurran
Variation in predation risk is a major driver of ecological and evolutionary change, and, in turn, of geographical variation in behaviour. While predation risk is rarely constant in natural populations, the extent to which variation in predation risk shapes individual behaviour in wild populations remains unclear. Here, we investigated individual differences in reproductive behavior in 16 Trinidadian guppy populations and related it to the observed variation in predator biomass each population experienced. Our results show...

Data from: Eating down the food chain: generalism is not an evolutionary dead end for herbivores

Danny Rojas, Maria João Ramos Pereira, Carlos Fonseca & Liliana M. Dávalos
The role of trophic specialisation in taxonomic diversification remains unclear. Plant specialists diversify faster than omnivores and animalivores, but at shorter macroevolutionary scales this pattern sometimes reverses. Here, we estimate the effect of diet diversification on speciation rates in noctilionoid bats, controlling for tree shape, rate heterogeneity and macroevolutionary regimes. We hypothesise that niche subdivision among herbivores positively relates to speciation rates, differing between macroevolutionary regimes. We found the rate at which new herbivorous lineages...

Data from: Vocal foragers and silent crowds: context-dependent vocal variation in Northeast Atlantic long-finned pilot whales

Fleur Visser, Annebelle C. M. Kok, M. G. Oudejans, Lindesay A. S. Scott-Hayward, Stacy L. DeRuiter, Ana C. Alves, Ricardo N. Antunes, Saana Isojunno, Graham J. Pierce, Hans Slabbekoorn, Jef Huisman, Patrick J. O. Miller & Annebelle C.M. Kok
Vocalisations form a key component of the social interactions and foraging behaviour of toothed whales. We investigated changes in calling and echolocation behaviour of long-finned pilot whales between foraging and non-foraging periods, by combining acoustic recordings and diving depth data from tagged individuals with concurrent surface observations on social behaviour of their group. The pilot whales showed marked vocal variation, specific to foraging and social context. During periods of foraging, pilot whales showed more vocal...

Data from: Towards robust evolutionary inference with integral projection models

M. J. Janeiro, D. W. Coltman, M. Festa-Bianchet, F. Pelletier & M. B. Morrissey
Integral projection models (IPMs) are extremely flexible tools for ecological and evolutionary inference. IPMs track the distribution of phenotype in populations through time, using functions describing phenotype-dependent development, inheritance, survival and fecundity. For evolutionary inference, two important features of any model are the ability to (i) characterize relationships among traits (including values of the same traits across ages) within individuals, and (ii) characterize similarity between individuals and their descendants. In IPM analyses, the former depends...

Data from: Climate and anthropogenic factors determine site occupancy in Scotland's Northern-range badger population: implications of context-dependent responses under environmental change

André P. Silva, Gonçalo Curveira-Santos, Kerry Kilshaw, Chris Newman, David W. Macdonald, Luciana G. Simões & Luís M. Rosalino
Aim In the light of human-induced rapid environmental change (HIREC), populations are exposed to ever-greater bioclimatic stress at the edge of a species’ historic range. The distribution dynamics of European badgers (Meles meles) at their southern edge are linked tightly to climatic variability. We contribute critical data on how climatic context and local factors determine site occupancy in a northern-range population. Location Eleven study areas (averaging ~21.3 km2) spread over ~50,000 km2 in Northern Scotland....

Data from: Interplay between fungicides and parasites: tebuconazole, but not copper, suppresses infection in a Daphnia-Metschnikowia experimental model

Ana Patrícia Cuco, Nelson Abrantes, Fernando Gonçalves, Justyna Wolinska & Bruno B. Castro
Natural populations are commonly exposed to complex stress scenarios, including anthropogenic contamination and their biological enemies (e.g., parasites). The study of the pollutant-parasite interplay is especially important, given the need for adequate regulations to promote improved ecosystem protection. In this study, a host-parasite model system (Daphnia spp. and the microparasitic yeast Metschnikowia bicuspidata) was used to explore the reciprocal effects of contamination by common agrochemical fungicides (copper sulphate and tebuconazole) and parasite challenge. We conducted...
