Data from: Predator size and prey size-gut capacity ratios determine kill frequency and carcass production in terrestrial carnivorous mammals

Annelies De Cuyper, Marcus Clauss, Chris Carbone, Daryl Codron, An Cools, Myriam Hesta & Geert P. J. Janssens
Carnivore kill frequency is a fundamental part of predator-prey interactions, which are important shapers of ecosystems. Current field kill frequency data are rare and existing models are insufficiently adapted to carnivore functional groups. We developed a kill frequency model accounting for carnivore mass, prey mass, pack size, partial consumption of prey and carnivore gut capacity. Two main carnivore functional groups, small prey-feeders vs large prey-feeders, were established based on the relationship between stomach capacity (C)...

Data from: Habitat fragmentation, not habitat loss, drives the prevalence of blood parasites in a Caribbean passerine

Antón Pérez-Rodríguez, Aurélie Khimoun, Anthony Ollivier, Cyril Eraud, B. Faivre & S. Garnier
Habitat destruction due to human land-use activities is well recognized as a central threat to biodiversity. However, there is still debate about the relative influence of its two components, habitat loss and habitat fragmentation, mostly because few studies have been able to disentangle their respective effects. We studied mechanisms by which habitat destruction might influence the prevalence of vector-transmitted haemosporidian blood parasites of the genera Plasmodium and Haemoproteus the Lesser Antillean Bullfinch, Loxigilla noctis, on...

Data from: Contrasting evolutionary history, anthropogenic declines and genetic contact in the northern and southern white rhinoceros (Ceratotherium simum)

Yoshan Moodley, Isa-Rita M. Russo, Jan Robovský, Desire Lee Dalton, Antoinette Kotze, Steve Smith, Jan Stejskal, Oliver A. Ryder, Robert Hermes, Chris Walzer & Michael W. Bruford
The white rhinoceros (Ceratotherium simum) has a discontinuous African distribution, which is limited by the extent of sub-Saharan grasslands. The southern population (SWR) declined to its lowest number around the turn of the 19th century, but recovered to become the world’s most numerous rhinoceros. In contrast, the northern population (NWR) was common during much of the 20th century, declining rapidly since the 1970s, and now only two post-reproductive individuals remain. Despite this species’ conservation status,...

Data from: Sacrificial males: the potential role of copulation and predation in contributing to copepod sex-skewed ratios

Predation is thought to play a selective role in the emergence of behavioural traits in prey. Differences in behaviour between prey demographics may, therefore, be driven by predation with select components of the population being less vulnerable to predators. While under controlled conditions prey demography has been shown to have consequences for predation success, investigations linking these implications to natural prey population demographics are scarce. Here we assess predator-prey dynamics between notonectid predators (backswimmers) and...

Data from: Venom gland size and venom complexity – essential trophic adaptations of venomous predators: a case study using spiders

Stano Pekár, Ondrej Bocanek, Ondrej Michalek, Lenka Petráková, Charles R. Haddad, Ondrej Sedo & Zbynek Zdrahal
Specialised predators possess variety of adaptations. In the venomous predators this may include size of the venom gland and venom composition. It is expected that due to different foraging strategies predators with a wide trophic niche (generalists) should possess larger venom glands that contain more diversified components than species with a narrow niche (specialists). We focused on spiders, as the most diversified group of venomous predators, in which a wide variety of trophic strategies has...

Data from: Mapping phosphorus hotspots in Sydney’s organic wastes: a spatially-explicit inventory to facilitate urban phosphorus recycling

Genevieve S. Metson, Dana Cordell, Brad Ridoutt & Steve Mohr
Phosphorus is an essential element for food production whose main global sources are becoming scarce and expensive. Furthermore, losses of phosphorus throughout the food production chain can also cause serious aquatic pollution. Recycling urban organic waste resources high in phosphorus could simultaneously address scarcity concerns for agricultural producers who reply on phosphorus fertilisers, and waste managers seeking to divert waste from landfills to decrease environmental burdens. Recycling phosphorus back to agricultural lands however requires careful...

Data from: Water for African elephants (Loxodonta Africana): faecal microbial loads affect use of artificial waterholes

Mduduzi Ndlovu, Antón Pérez-Rodríguez, Emma Devereux, Miranda Thomas, Alfredo Colina & Linford Molaba
In semi-arid protected areas artificial waterholes ensure that water is locally available to animals for extended periods. However, artificial waterholes may limit animal movement, which contributes towards habitat deterioration. Challenges of artificial water provisioning worsen in the presence of ecosystem engineers like African elephants Loxodonta africana, capable of transforming environments. Camera traps were used to monitor elephant visitation at 21 artificial waterholes in the Kruger National Park, South Africa. We also assessed if water quality...
