Data from: Urbanization and the temporal patterns of social networks and group foraging behaviours

Teri B. Jones, Julian C. Evans & Julie Morand-Ferron
Urbanization causes dramatic and rapid changes to natural environments, which can lead the animals inhabiting these habitats to adjust their behavioral responses. For social animals, urbanized environments may alter group social dynamics through modification of the external environment (e.g., resource distribution). This might lead to changes in how individuals associate or engage in group behaviors, which could alter the stability and characteristics of social groups. However, the potential impacts of urban habitat use, and of...

Selection for increased male size predicts variation in sexual size dimorphism among fish species

Curtis Horne, Andrew Hirst & David Atkinson
Variation in the degree of sexual size dimorphism (SSD) among taxa is generally considered to arise from differences in the relative intensity of male-male competition and fecundity selection. One might predict, therefore, that SSD will vary systematically with: 1) the intensity of sexual selection for increased male size, and 2) the intensity of fecundity selection for increased female size. To test these two fundamental hypotheses, we conducted a phylogenetic comparative analysis of SSD in fish....

Drought and presence of ants can influence hemipitera in tropical leaf litter

Anna Goldman, Timothy Bonebrake, Theodore Evans, Hannah Griffiths, Catherine Parr, Louise Ashton & Paul Eggleton
Climate change is predicted to impact tropical rainforests, with droughts becoming more frequent and more severe in some regions. We currently have a poor understanding of how increased drought will change the functioning of tropical rainforest. In particular, tropical rainforest invertebrates, which are numerous and biologically important, may respond to drought in different ways across trophic levels. Ants are a diverse group that carry out important ecosystem processes, shaping ecosystem structure and function through predation...

Wood decomposition data from an experiment in Malaysian Borneo, 2015-2018

S.J. Law, L. Ashton, H. Griffiths, P. Eggleton & C. Parr
This dataset measures the decomposition of experimental wood blocks, Pinus radiata, over a period of one year in lowland, old growth, tropical rainforest. Wood blocks are placed on the ground or suspended above the ground in mesh bags that either allow or prevent entry of macro-invertebrates. The decomposition of ground placed wood blocks is measured during a period of drought and non-drought. Dry weight of wood blocks is measured at the start and end of...

Bait use of arboreal ants in a lowland tropical rainforest, Maliau Basin Conservation Area, Malaysia, 2015-2018

S. Law & C. Parr
This dataset measures the abundance of ant species at baited traps set across 12 trees in four experimental plots in lowland, tropical rainforest. Baited traps were set at 5 m vertical intervals from the ground to as high as possible in the canopy, the stratum of each trap location was recorded. At each height 2 pairs of baited traps were set, each pair contained one trap baited with carbohydrate (honey and oats) and the second...

Interspecific communication in African savannah herbivores

J. Bro-Jorgensen, D.W. Franks & K. Meise
This dataset contains information about various aspects of the alarm communication network of African savannah herbivores. Data were collected in April 2015 and between September 2015 and October 2016 in the Masai Mara National Reserve, in southern Kenya (1°30’S, 35°10’E). Research focused on the 12 most common herbivore species in the ecosystem. For each of these species, the dataset provides information on vigilance rates, the probability to alarm call in response to different predators, the...

Mosquito trap data from Kilombero Valley in Tanzania - a global hotspot for malaria. Since 2007, field entomologists working at Ifakara Health Institue (IHI) and at the University of Glasgow have been trapping and collecting primary malaria vectors for four villages in the Kilombero Valley: Lupiro, Kidugalo, Minepa and Sagamaganga. Trapped mosquitoes were identified to species level (Anopheles gambiae and A funestus), their sex recorded (male or female) and their abdominal status (fed or unfed)...

Ant colour data from an experiment in Malaysian Borneo, 2015-2018.

S. Law, T.R. Bishop, P. Eggleton, H.M. Griffiths, L. Ashton & C. Parr
This dataset measures colour and estimates body size of ant species collected across four vertical strata: subterranean, ground, understory and canopy in lowland tropical rainforest. Ants were collected using different trapping techniques in each stratum; baited traps were used in the subterranean, understory and canopy strata and Winkler extractions were used to collect ground ants. The colour of each ant species was classified categorically by eye using a set pre-determined colours. A single dominant colour...

N.D. Gray, R.C. Hastings, S.K. Sheppard, P. Loughnane, D. Lloyd, A.J. McCarthy & I.M. Head
This set of data comprises temporal temperature gradient electrophoresis (TTGE) and soil process measurements, used to analyse the effects of perturbations (sludge and/or lime application) on the structure, community development and activity of bacteria that catalyse fundamental processes in upland soils. These were collected to address the following questions: Do soil improvement treatments select for particular components of bacterial populations and hence drive community development? If so, at what functional and phylogenetic level is this...

Data from: Resource heterogeneity and the evolution of public-goods cooperation

Peter Stilwell, Siobhan O'Brien, Elze Hesse, Chris Lowe, Andy Gardner & Angus Buckling
Heterogeneity in resources is a ubiquitous feature of natural landscapes affecting many aspects of biology. However, the effect of environmental heterogeneity on the evolution of cooperation has been less well studied. Here, using a mixture of theory and experiments measuring siderophore production by the bacterium Pseudomonas aeruginosa as a model for public-goods based cooperation, we show that cooperation in metapopulations that were spatially heterogeneous in terms of resources can be maintained at a higher level...

Ana P. B. Carneiro, Elizabeth J. Pearmain, Steffen Oppel, Thomas A. Clay, Richard A. Phillips, Anne-Sophie Bonnet-Lebrun, Ross M. Wanless, Edward Abraham, Yvan Richard, Joel Rice, Jonathan Handley, Tammy E. Davies, Ben J. Dilley, Peter G. Ryan, Cleo Small, Javier Arata, John P. Y. Arnould, Elizabeth Bell, Leandro Bugoni, Letizia Campioni, Paulo Catry, Jaimie Cleeland, Lorna Deppe, Graeme Elliott, Amanda Freeman … & Maria P. Dias
1. The identification of geographic areas where the densities of animals are highest across their annual cycles is a crucial step in conservation planning. In marine environments, however, it can be particularly difficult to map the distribution of species, and the methods used are usually biased towards adults, neglecting the distribution of other life-history stages even though they can represent a substantial proportion of the total population. 2. Here we develop a methodological framework for...

Prey density affects predator foraging strategy in an Antarctic ecosystem

Karl Busdieker, Samantha Patrick, Alice Trevail & Sébastien Descamps
Studying the effects of prey distribution on predator behaviour is complex in systems where there are multiple prey species. The role of prey density in predator behaviour is rarely studied in closed ecosystems of one predator species and one prey species, despite these being an ideal opportunity to test these hypotheses. In this study, we investigate the effect of prey density on the foraging behaviour of a predatory species in an isolated Antarctic ecosystem of...

Differential impact of nevirapine on artemether-lumefantrine pharmacokinetics in individuals stratified by CYP2B6 c.516G>T genotypes

Sa'ad Abdullahi, Julius Soyinka, Adeniyi Olagunju, Rahman Bolarinwa, Olusola Olarewaju, Moji Bakare-Odunola, Markus Winterberg, Joel Tarning, Andrew Owen & Saye Khoo
There is an increased recognition of the need to identify and quantify the impact of genetic polymorphisms on drug-drug interactions. This study investigated the pharmacogenetics of the pharmacokinetic drug-drug interaction between nevirapine and artemether-lumefantrine in HIV-positive and HIV-negative adult Nigerian subjects. Thirty each of HIV-infected patients on nevirapine-based antiretroviral therapy and HIV-negative volunteers without clinical malaria, but with predetermined CYP2B6 c.516GG and TT genotypes were administered a complete treatment dose of 3-days of artemether-lumefantrine. Rich...
