1. Large carnivores of the genus Panthera can pose serious threats to public safety. Although the annual number of attacks on humans is rare compared to livestock depredation, such incidents undermine popular support for wildlife conservation and require immediate responses to protect human life. 2. We used a space-time scan method to perform a novel spatiotemporal analysis of 908 attacks on humans by lions, leopards and tigers to estimate the risks of further attacks in...

MacDougall, Rebecca L. McCulley, Suzanne M. Prober, Anita C. Risch, Mahesh Sankaran, Martin Schütz, Eric W. Seabloom, Carly J. Stevens, Lauren L. Sullivan, Peter D. Wragg & Elizabeth T. Borer
Plant stoichiometry, the relative concentration of elements, is a key regulator of ecosystem functioning and is also being altered by human activities. In this paper we sought to understand the global drivers of plant stoichiometry and compare the relative contribution of climatic vs. anthropogenic effects. We addressed this goal by measuring plant elemental (C, N, P and K) responses to eutrophication and vertebrate herbivore exclusion at eighteen sites on six continents. Across sites, climate and...

Data from: Topographic mapping of the interfaces between human and aquatic mosquito habitats to enable barrier-targeting of interventions against malaria vectors

Victoria M. Mwakalinga, Benn K.D. Sartorius, Alex J. Limwagu, Yeromin P. Mlacha, Daniel F. Msellemu, Prosper P. Chaki, Nicoderm J. Govella, Maureen Coetzee, Stefan Dongus, Gerry F. Killeen, Nicodem J. Govella & Benn K. D. Sartorius
Geophysical topographic metrics of local water-accumulation potential are freely available and have long been known as high resolution predictors of where aquatic habitats for immature Anopheles mosquitoes are most abundant, resulting in elevated densities of adult malaria vectors and human infection burden. Using existing entomological and epidemiological survey data, here we illustrate how topography can also be used to map out the interfaces between wet, unoccupied valleys and dry, densely populated uplands, where malaria vector...

Data from: Demography and social dynamics of an African elephant population 35 years after reintroduction as juveniles

Timothy R. Kuiper, Dave J. Druce & Heleen C. Druce
1. Given their vulnerability to local extinction, the reintroduction of megafauna species (often long-lived, ecologically-influential and highly-social) is an increasingly relevant conservation intervention. Studies that evaluate past megafauna reintroductions are both critical and rare. 2. Between 1981 and 1996, 12 cohorts of a total of 200 juvenile (<5 years old) African savanna elephants (Loxodonta africana africana) were re-introduced to Hluhluwe-iMfolozi Park (HiP), South Africa, after 100 years of absence. Here we model the population’s long...

Data from: Thermal resilience may shape population abundance of two sympatric congeneric Cotesia species (Hymenoptera: Braconidae)

Reyard Mutamiswa, Honest Machekano, Frank Chidawanyika & Casper Nyamukondiwa
Basal and plasticity of thermal tolerance determine abundance, biogeographical patterns and activity of insects over spatial and temporal scales. For coexisting stemborer parasitoids, offering synergistic impact to the efficacy of biological control, mismatches in thermal tolerance may influence their ultimate impact in biocontrol programs under climate variability. Using laboratory-reared congeneric parasitoid species Cotesia sesamiae and Cotesia flavipes Cameron (Hymenoptera: Braconidae), we examined basal thermal tolerance to understand potential impact of climate variability on their survival...

Data from: Foraging efficiency and size matching in a plant – pollinator community: the importance of sugar content and tongue length

Saskia G.T. Klumpers, Martina Stang & Peter G.L. Klinkhamer
A longstanding question in ecology is how species interactions are structured within communities. Although evolutionary theory predicts close size matching between floral nectar tube depth and pollinator proboscis length of interacting species, such size matching has seldom been shown and explained in multispecies assemblages. Here, we investigated the degree of size matching among Asteraceae and their pollinators and its relationship with foraging efficiency. The majority of pollinators, especially Hymenoptera, choose plant species on which they...

Data from: Floral community predicts pollinators' color preference: implications for Batesian floral mimicry

Michael R. Whitehead, Anne C. Gaskett, Steve D. Johnson & Steven D Johnson
Animals that rely on nectar are expected to display floral trait preferences correlating to the signals of nectar source flowers. Batesian mimicry evolves to exploit these pre-existing signal-receiver relationships, attracting pollinators through an adaptive resemblance to specific co-occurring rewarding species. The nectar-feeding long-proboscid flies of South Africa are pollinators for several deceptive orchid species that are putatively Batesian mimics. We tested whether flies’ measured color preference varied among communities providing different nectar-source diets, which would...

Data from: Lion population dynamics: do nomadic males matter?

Natalia Borrego, Arpat Ozgul, Rob Slotow & Craig Packer
Key population processes are sometimes driven by male dynamics, but these drivers are often overlooked because of the scale over which they operate. Lions (Panthera leo) provide an ideal case study for investigating factors governing male dynamics and their influence on population sustainability. Lions display sexually selected infanticide, and resident males must defend their offspring from nomads that may have dispersed over long distances; factors affecting male-male competition over large spatial scales can have population...

Data from: Seascape genetics of the spiny lobster Panulirus homarus in the Western Indian Ocean: understanding how oceanographic features shape the genetic structure of species with high larval dispersal potential

Sohana P. Singh, Johan C. Groeneveld, Michael G. Hart-Davis, Björn C. Backeberg & Sandi Willows-Munro
This study examines the fine-scale population genetic structure and phylogeography of the spiny lobster Panulirus homarus in the Western Indian Ocean. A seascape genetics approach was used to relate the observed genetic structure based on 21 microsatellite loci to ocean circulation patterns, and to determine the influence of latitude, sea surface temperature (SST) and ocean turbidity (KD490) on population-level processes. At a geospatial level, the genetic clusters recovered corresponded to three putative subspecies, P. h....

Data from: Weak population structure of the Spot-tail shark Carcharhinus sorrah and the Blacktip shark C. limbatus along the coasts of the Arabian Peninsula, Pakistan and South Africa

Dareen Almojil, Geremy Cliff, Julia L.Y. Spaet & Julia L. Y. Spaet
The increase in demand for shark meat and fins has placed shark populations worldwide under high fishing pressure. In the Arabian region, the Spot-tail shark Carcharhinus sorrah and the Blacktip shark Carcharhinus limbatus are among the most exploited species. In this study we investigated the population genetic structure of C. sorrah (n= 327) along the coasts of the Arabian Peninsula and of C. limbatus (n= 525) along the Arabian coasts, Pakistan and KwaZulu-Natal, South Africa...

Data from: Landscape genomics and pathway analysis to understand genetic adaptation of South African indigenous goat populations

Khanyisile Mdladla, Edgar F. Dzomba & Farai C. Muchadeyi
Extensively raised livestock populations in most smallholder farming communities are exposed to harsh and heterogeneous climates and disease pathogen that they adapt to in order to survive. Majority of these livestock species including goats are of non-descript breeds and their response to natural selection presented by heterogeneous environments is still unresolved. This study investigated genetic diversity and its association with environmental and geographic conditions in 194 South African indigenous goats from different geographic using Illumina...

Data from: Food quality and quantity is more important in explaining foraging of an intermediate-sized mammalian herbivore than predation risk or competition

Martijn J.A. Weterings, Sander Moonen, Herbert H.T. Prins, Sipke E. Van Wieren, Frank Van Langevelde, Martijn J. A. Weterings & Herbert H. T. Prins
During times of high activity by predators and competitors, herbivores may be forced to forage in patches of low-quality food. However, the relative importance in determining where and what herbivores forage still remains unclear, especially for small and intermediate-sized herbivores. Our objective was to test the relative importance of predator and competitor activity, and forage quality and quantity on the proportion of time spent in a vegetation type and the proportion of time spent foraging...
