Visual obstruction, but not moderate traffic noise, increases reliance on heterospecific alarm calls

Chaminda Ratnayake, You Zhou, Francesca Dawson Pell, Dominique Potvin, Andrew Radford & Robert Magrath
Animals rely on both personal and social information about danger to minimise risk, yet environmental conditions constrain information. Both visual obstructions and background noise can reduce detectability of predators, which may increase reliance on social information, such as from alarm calls. Furthermore, a combination of visual and auditory constraints might greatly increase reliance on social information, because the loss of information from one source cannot be compensated by the other. Testing these possibilities requires manipulating...

Data from: Upland rush management advocated by agri-environment schemes increases predation of artificial wader nests

Leah Kelly, David Douglas, Mike Shurmer & Karl Evans
Farmland birds, including breeding waders, have declined across Europe. One frequently advocated strategy to facilitate population recovery is using agri-environment schemes (AES) to improve vegetation structure. A key example is cutting dense rush Juncus to open the sward which aims to increase the abundance of wading birds, for example by improving foraging conditions. Effects on breeding success are, however, unknown. This is a critical knowledge gap as high nest and chick predation rates are a...

Anisogamy is unrelated to the intensity of sexual selection

Judit Mokos, István Scheuring, András Liker, Robert P. Freckelton & Tamás Székely
Males and females often display different behaviours and, in the context of reproduction, these behaviours are labelled sex roles. The Darwin–Bateman paradigm argues that the root of these differences is anisogamy (i.e., differences in size and/or function of gametes between the sexes) that leads to biased sexual selection, and sex differences in parental care and body size. This evolutionary cascade, however, is contentious since some of the underpinning assumptions have been questioned. Here we investigate...

Exceptionally high apparent adult survival in three tropical species of plovers in Madagascar

William Jones, Luke Eberhart-Hertel, Robert Freckleton, Joseph Hoffmann, Oliver Krüger, Brett Sandercock, Orsolya Vincze, Sama Zefania & Tamás Székely
Adult survival is a key component of population dynamics and understanding variation in and the drivers of adult survival rates and longevity is critical for ecological and evolutionary studies, as well as for conservation biology and practice. Tropical species of landbirds are often selected to have higher adult survival due to high nest predation rates, but it is unclear if the same patterns occur in other avian lineages with different life history strategies. Here, we...

Survey data of greenspace users' preference scores for planted urban meadows and demographic data, Bedford and Luton, UK, 2014

K.L. Evans, G.E. Southon, N. Dunnett, H. Hoyle, A. Jorgensen & L. Jones
The data comprise outcomes from questionnaire surveys conducted with greenspace users on their perceptions of experimentally manipulated urban meadows (varying levels of diversity and vegetation height of sown wildflower meadows), and associated socio-economic data of respondents to the questionnaire surveys. The experimental meadows were located in Bedford and Luton. Data was collected by the data authors, and participants gave informed consent before completing the questionnaires. The work was initially completed under the Fragments, functions and...

Fine-scale genetic structure reflects limited and coordinated dispersal in the colonial monk parakeet, Myiopsitta monachus

Francesca Dawson Pell, Juan Carlos Senar, Daniel Franks & Ben Hatchwell
The genetic structure of animal populations has considerable behavioural, ecological and evolutionary implications and may arise from various demographic traits. Here, we use observational field data and molecular genetics to determine the genetic structure of an invasive population of monk parakeets, Myiopsitta monachus, at a range of spatial scales, and investigate the demographic processes that generate the observed structure. Monk parakeets construct large nests that can house several pairs occupying separate chambers; these nests are...

Data from: Socio-ecological conditions and female infidelity in the Seychelles warbler

Sara Raj Pant, Jan Komdeur, Terry A. Burke, Hannah L. Dugdale & David S. Richardson
Within socially monogamous breeding systems, levels of extra-pair paternity can vary not only between species, populations and individuals, but also across time. Uncovering how different extrinsic conditions (ecological, demographic and social) influence this behavior will help shed light on the factors driving its evolution. Here, we simultaneously address multiple socio-ecological conditions potentially influencing female infidelity in a natural population of the cooperatively breeding Seychelles warbler, Acrocephalus sechellensis. Our contained study population has been monitored for...

Early‐life seasonal, weather and social effects on telomere length in a wild mammal

Sil H.J. Van Lieshout, Elisa P. Badás, Julius G. Bright Ross, Amanda Bretman, Chris Newman, Christina D. Buesching, Terry Burke, David W. Macdonald & Hannah L. Dugdale
Early-life environmental conditions can provide a source of individual variation in life-history strategies and senescence patterns. Conditions experienced in early life can be quantified by measuring telomere length, which can act as a biomarker of survival probability in some species. Here, we investigate whether seasonal changes, weather conditions, and group size are associated with early-life and/or early-adulthood telomere length in a wild population of European badgers (Meles meles). We found substantial intra-annual changes in telomere...

An experimental test of the impact of avian diversity on attentional benefits and enjoyment of people experiencing urban green-space

Joseph Douglas & Karl Evans
Biodiversity may play a key role in generating the well-being benefits of visiting green-spaces. The ability of people to accurately perceive variation in biodiversity is, however, unclear and evidence supporting links between biodiversity exposure and well-being outcomes remains equivocal. In part, this is due to the paucity of controlled experimental studies that deal adequately with confounding factors that covary with biodiversity. Attention restoration theory (ART) proposes that natural environments contain many softly fascinating stimuli that...

Short-term exposure to silicon rapidly enhances plant resistance to herbivory

Jamie Waterman, Ximena Cibils-Stewart, Christopher Cazzonelli, Susan Hartley & Scott Johnson
Silicon (Si) can adversely affect insect herbivores, particularly in plants that evolved the ability to accumulate large quantities of Si. Very rapid herbivore-induced accumulation of Si has recently been demonstrated, but the level of protection against herbivory this affords plants remains unknown. Brachypodium distachyon, a model Si hyperaccumulating grass, was exposed to the chewing herbivore, Helicoverpa armigera, and grown under three conditions: supplied Si over 34 days (+Si), not supplied Si (-Si), or supplied Si...

Large seeds provide an intrinsic growth advantage that depends on leaf traits and root allocation

Kimberley Simpson, Rebecca Atkinson, Emily Mockford, Chris Bennett, Colin Osborne & Mark Rees
Seed mass and growth rate are important dimensions of plant ecological diversity, but their relationship remains unresolved. Negative relationships between relative growth rate (RGR) and seed mass are well established. However, RGR is size-dependent, so small-seeded species might achieve fast growth simply because they are initially small. Using a dataset of unprecedented size, sampling 382 grass species, we investigated seed mass and growth rate using both RGR and SGR (RGR at a specific size), accounting...
