Predicting habitat suitability for wild deer in relation to threatened ecological communities in south-eastern New South Wales, Australia

Heather Burns, Philip Gibbons, Andrew Claridge & David McCreery
Context. High density deer populations can cause ecological damage, yet their distribution and impacts are poorly known across much of Australia. As a result, land managers rely on anecdotal reports to make decisions about management and control measures. Aims. We aimed to model habitat suitability for deer in the South Coast of New South Wales (NSW), Australia, to be used as a baseline for future management and identify which threatened ecological communities (TECs) in the...

Data from: Integrated population modelling reveals a perceived source to be a cryptic sink

Mitch D. Weegman, Stuart Bearhop, Anthony D. Fox, Geoff M. Hilton, Alyn J. Walsh, Jennifer L. McDonald & David J. Hodgson
Demographic links among fragmented populations are commonly studied as source-sink dynamics, whereby source populations exhibit net recruitment and net emigration, while sinks suffer net mortality but enjoy net immigration. It is commonly assumed that large, persistent aggregations of individuals must be sources, but this ignores the possibility that they are sinks instead, buoyed demographically by immigration. We tested this assumption using Bayesian integrated population modelling of Greenland white-fronted geese (Anser albifrons flavirostris) at their largest...

Data from: Local-scale tree and shrub diversity improves pollination services to shea trees in tropical West African parklands

Aoife Delaney, Assita Dembele, Issa Nombre, Franck Gnane Lirasse, Elaine Marshall, Adama Nana, Juliet Vickery, Cath Tayleur & Jane Stout
Shea (Vitellaria paradoxa) trees bear fruit and seeds of considerable economic, nutritional and cultural value in the African Sudano-Sahelian zone. In much of West Africa, shea exists within an agroforestry system referred to as “Parkland”, where social changes, including migration, have resulted in expanding areas of crop cultivation, reductions in both the area of fallow land and the duration of fallow periods, and reduced diversity of habitats and woody species. Shea benefits strongly from pollination...

Data from: Artificial agri-environment scheme ponds do not replicate natural environments despite higher aquatic and terrestrial invertebrate richness and abundance

Marina Reyne, Myles Nolan, Harry McGuiggan, Aureli Aubry, Mark Emmerson, Ferdia Marnell & Neil Reid
1. Farmland ponds are a highly threatened freshwater habitat which has undergone dramatic losses during the last 200 years due to land drainage schemes and agricultural intensification. Agri-environment schemes (AES) incentivise farmers to adopt farming methods to benefit biodiversity, yet there are a paucity of data evaluating the success of artificially created AES ponds as analogues of natural ponds in an attempt to recreate lost environments. 2. We examined variation in environmental parameters and aquatic...

Data from: Plant traits of propagule banks and standing vegetation reveal flooding alleviates impacts of agriculture on wetland restoration

Samantha K. Dawson, David I. Warton, Richard T. Kingsford, Peter Berney, David A. Keith & Jane A. Catford
1. Restoration of degraded plant communities requires understanding of community assembly processes. Human land use can influence plant community assembly by altering environmental conditions and species’ dispersal patterns. Flooding, including from environmental flows, may counteract land use effects on wetland vegetation. We examined the influence of land use history and flood frequency on the functional composition of wetland plant communities along a regulated river. 2. We applied fourth corner modelling to determine species’ trait-based responses...

Data from: Dispersal patterns in a medium-density Irish badger population: implications for understanding the dynamics of tuberculosis transmission.

Aoibheann Gaughran, Teresa MacWhite, Enda Mullen, Peter Maher, David Kelly, Nicola Marples & Margaret Good
European badgers (Meles meles) are group-living mustelids implicated in the spread of bovine tuberculosis (TB) to cattle and act as a wildlife reservoir for the disease. In badgers, only a minority of individuals disperse from their natal social group. However, dispersal may be extremely important for the spread of TB, as dispersers could act as hubs for disease transmission. We monitored a population of 139 wild badgers over seven years in a medium-density population (1.8...

Microplastics in Eurasian otter (Lutra lutra) spraints and their potential as a biomonitoring tool in freshwater systems

James D. O'Connor, Heather T. Lally, Anne-Marie Mahon, Ian O'Connor, Róisín Nash, John J. O'Sullivan, Michael Bruen, Linda Heerey, Albert A. Koelmans, Ferdia Marnell & Sinéad Murphy
The ubiquitous nature of microplastics in aquatic ecosystems may have serious implications for aquatic biota. While microplastic research in freshwater ecosystems is increasing, very few studies have assessed the physical presence of microplastics among top predators. The Eurasian otter (Lutra lutra), a top predator of aquatic ecosystems, is one of the most widely distributed otter species and has a broad habitat niche. The opportunistic collection of otter spraints (i.e. feces) presents a valuable opportunity to...
