Sperm function and quality are primary determinants of male reproductive performance and hence fitness. The presence of rival males has been shown to affect ejaculate and sperm traits in a wide range of taxa. However, male physiological conditions may not only affect sperm phenotypic traits but also their genetic and epigenetic signatures, affecting the fitness of the resulting offspring. We investigated the effects of male-male competition on sperm quality using TUNEL assays and geometric morphometrics...
Data from: Abundance drives broad patterns of generalisation in plant-hummingbird pollination networksBenno I. Simmons, Jeferson Vizentin-Bugoni, Pietro K. Maruyama, Peter A. Cotton, Oscar H. Marín-Gómez, Carlos Lara, Liliana Rosero-Lasprilla, María A Maglianesi, Raúl Ortiz-Pulido, Márcia A. Rocca, Licléia C. Rodrigues, Boris Tinocco, Marcelo F. Vasconcelos, Marlies Sazima, Ana M. Martín González, Jesper Sonne, Carsten Rahbek, Lynn V. Dicks, Bo Dalsgaard & William J. Sutherland
Abundant pollinators are often more generalised than rare pollinators. This could be because abundant species have more chance encounters with potential interaction partners. On the other hand, generalised species could have a competitive advantage over specialists, leading to higher abundance. Determining the direction of the abundance-generalisation relationship is therefore a ‘chicken-and-egg’ dilemma. Here we determine the direction of the relationship between abundance and generalisation in plant-hummingbird pollination networks across the Americas. We find evidence that...
Survival and reproductive success of migrant and resident wildlife in published studies of partially migratory populationsC. Buchan, J.J. Gilroy, I. Catry & A.M.A. Franco
This is a dataset generated from information extracted from previously published studies, for the purpose of a meta-analysis investigating fitness benefits of different migratory strategies in partially migratory populations. Each line of data includes a mean and associated variance for a given fitness metric for both migrants and residents extracted from a study, in addition to information concerning population location, study species, type of fitness metric, year data were collected, and details on the publication...
Data from: Experimentally induced anti-predator responses are mediated by social and environmental factorsFrank Groenewoud, Sjouke A. Kingma, Kat Bebbington, David Richardson & Jan Komdeur
Nest predation is a common cause of reproductive failure for many bird species, and various anti-predator defense behaviors have evolved to reduce the risk of nest predation. However, trade-offs between current reproductive duties and future reproduction often limit the parent’s ability to respond to nest predation risk. Individual responses to experimentally increased nest predation risk can give insights into these trade-offs. Here, we investigate whether social and ecological factors affect individual responses to predation risk...
Data from: Rubber agroforestry in Thailand provides some biodiversity benefits without reducing yieldsEleanor Warren-Thomas, Luke Nelson, Watinee Juthong, Sara Bumrungsri, Oskar Brattström, Laetitia Stroesser, Bénédicte Chambon, Éric Penot, Uraiwan Tongkaemkew, David P. Edwards & Paul M. Dolman
Monocultural rubber plantations have replaced tropical forest, causing biodiversity loss. While protecting intact or semi-intact biodiverse forest is paramount, improving biodiversity value within the 11.4 million hectares of existing rubber plantations could offer important conservation benefits, if yields are also maintained. Some farmers practice agroforestry with high-yielding clonal rubber varieties to increase and diversify incomes. Here, we ask whether such rubber agroforestry improves biodiversity value or affects rubber yields relative to monoculture. We surveyed birds,...
The wet weight in grams of gelatinous zooplankton (jellyfish) caught at each station during International Bottom Trawl Surveys in the North Sea from 2012 to 2018. Also included are associated station data which include datetime, location, depths, swept volume and information on gear deployment. Any blank values indicate the value was not recorded. Jellyfish data were collected using standard GOV fishing gear deployed from Cefas RV Endeavour, to carry out the International Bottom Trawl Survey...
Amazonia forest plays a major role in providing ecosystem services for human and sanctuaries for wildlife. However, ongoing deforestation and habitat fragmentation in the Brazilian Amazon has threatened both. The ocelot is an ecologically important mesopredator and a potential conservation ambassador species, yet there are no previous studies on its habitat preference and spatial patterns in this biome. From 2010 to 2017, twelve sites were surveyed, totaling 899 camera trap stations, the largest known dataset...
