Previous studies have demonstrated a correlation between longevity and brain size in a variety of taxa. Little research has been devoted to understanding this link in parrots; yet parrots are well-known for both their exceptionally long lives and cognitive complexity. We employed a large-scale comparative analysis that investigated the influence of brain size and life history variables on longevity in parrots. Specifically, we addressed two hypotheses for evolutionary drivers of longevity: the Cognitive Buffer Hypothesis,...
This dataset consists of home-range area summaries of four species of frugivores on Barro Colorado Island, Panama, including 12 kinkajou (Potos flavus), 16 white-nosed coati (Nasua narica), 8 white-faced capuchin monkey (Cebus capucinus), and 8 spider monkey (Ateles geoffroyi). Summaries include effective sample sizes (DOF) as well as parameter estimates (in hectares) including upper and lower confidence intervals. Metadata for each individual are provided including their indivdual ID and species ID. The summaries of the...
1. Accelerometers in animal-attached tags have proven to be powerful tools in behavioural ecology, being used to determine behaviour and provide proxies for movement-based energy expenditure. Researchers are collecting and archiving data across systems, seasons and device types. However, in order to use data repositories to draw ecological inference, we need to establish the error introduced according to sensor type and position on the study animal and establish protocols for error assessment and minimization. 2....
Assessing the effects of survey-inherent disturbance on primate detectability: Recommendations for line transect distance sampling.

Habitat destruction and over-hunting are increasingly threatening the arboreal primates of Central Africa. To establish effective conservation strategies, accurate assessments of primate density, abundance and spatial distribution are required. To date, the method of choice for primate density estimation is line transect distance sampling. However, primates fleeing human observers violate methodological assumptions, biasing the accuracy of resulting estimates. In this study, we used line transect distance sampling to study 5 primate species along 378 km...
All animals that operate within the atmospheric boundary layer need to respond to aerial turbulence. Yet little is known about how flying animals do this because evaluating turbulence at fine scales (tens to ~ 300 m) is exceedingly difficult. Recently, data from animal-borne sensors have been used to assess wind and updraft strength, providing a new possibility for sensing the physical environment. We tested whether highly-resolved changes in altitude and body acceleration measured onboard solo-flying...
Migrating grazers and carnivores respond to seasonal changes in the environment and often match peaks in resource abundance. However, it is unclear if and how frugivorous animals use phenological events to time migration, especially in the tropics. The straw-colored fruit bat (Eidolon helvum), Africa’s most gregarious fruit bat, forms large seasonal colonies throughout much of sub-Saharan Africa. We hypothesized that aggregations of E. helvum match the timing of their migration with phenologies of plant growth...
Wildlife alter their behaviors in a trade-off between consuming food and fear of becoming food themselves. The risk allocation hypothesis posits that variation in the scale, intensity, and longevity of predation threats can influence the magnitude of antipredator behavioral responses. Hunting by humans represents a threat to wildlife thought to be perceived as similar to those of a top predator, although hunting intensity and duration vary widely around the world. Here we evaluate the effects...
Hotspots in the grid: Avian sensitivity and vulnerability to collision risk from energy infrastructure interactions in Europe and North AfricaJethro George Gauld, João P. Silva, Philip W.

Wind turbines and power lines can cause bird mortality due to collision or electrocution. The biodiversity impacts of energy infrastructure (EI) can be minimised through effective landscape-scale planning and mitigation. The identification of high-vulnerability areas is urgently needed to assess potential cumulative impacts of EI while supporting the transition to zero-carbon energy. We collected GPS location data from 1,454 birds from 27 species susceptible to collision within Europe and North Africa and identified areas where...
This repository contains data to reproduce the manuscript titled "Cultural diffusion dynamics depend on behavioural production rules". These RDAs contain simulation data, as well as inference data from NBDA and EWA analyses. They are intended to be used with the analysis code found at www.github.com/michaelchimento/acquisition_production_abm.
We assesed the impact of the changes in climate on the overall skull size (the proxy of the overall body size) and the seasonal changes of skull height (Dehnel’s phenomenon) in skulls of the common shrew, Sorex araneus, collected over 50 years in the Białowieża Forest, E Poland. Overall skull size decreased, along with increasing temperatures and decreasing soil moisture, which determined the availability of the shrews’ main food source, earthworms. The magnitude of Dehnel’s...
