Declining invasive grey squirrel populations may persist in refugia as native predator recovery reverses squirrel species replacement

Joshua Twining, Ian Montgomery & David Tosh
Invasive species pose one the most serious global threats to biodiversity. Investigations into the interactions of native and non-native species focus on the impacts of single species, despite being embedded in a network of direct and indirect interactions between multiple species and their environments. We developed 1 km2 resolution, single-species and multi-species, occupancy models using quantitative camera trap data collected by citizen scientists at 332 sites in a regional survey comprising the 14,130 km2 of...

Data from: The global diversity and distribution of lizard clutch sizes

Shai Meiri, Luciano Avila, Aaron Bauer, David Chapple, Indraneil Das, Tiffany Doan, Paul Doughty, Ryan Ellis, Lee Grismer, Fred Kraus, Mariana Morando, Paul Oliver, Daniel Pincheira-Donoso, Marco-Antonio Ribeiro-Junior, Glenn Shea, Omar Torres-Carvajal, Alex Slavenko & Uri Roll
Aim. Clutch size is a key life-history trait. In lizards, it ranges over two orders of magnitude. The global drivers of spatial and phylogenetic variation in clutch have been extensively studied in birds, but such tests in other organisms are lacking. To test the generality of latitudinal gradients in clutch size, and their putative drivers, we present the first global-scale analysis of clutch sizes across of lizard taxa. Location, Global Time period. Recent Major taxa...

Data from: An annotated draft genome of the mountain hare (Lepus timidus)

João Pedro Marques, Fernando A. Seixas, Jeffrey M. Good, Liliana Farelo, Colin M. Callahan, W. Ian Montgomery, Neil Reid, Paulo C. Alves, Pierre Boursot & José Melo-Ferreira
Hares (genus Lepus) provide clear examples of repeated and often massive introgressive hybridization and striking local adaptations. Genomic studies on this group have so far relied on comparisons to the European rabbit (Oryctolagus cuniculus) reference genome. Here, we report the first de novo draft reference genome for a hare species, the mountain hare (Lepus timidus), and evaluate the efficacy of whole-genome re-sequencing analyses using the new reference versus using the rabbit reference genome. The genome...

Data from: Puma energetics: laboratory oxygen consumption and GPS information from free-ranging individuals

Terrie Williams, Nikki Marks, Christopher Wilmers, Caleb Bryce, Barry Nickel, Lisa Wolfe, David Scantlebury & Carolyn Dunford
Abstract Background Under current scenarios of climate change and habitat loss, many wild animals, especially large predators, are moving into novel energetically challenging environments. Consequently, changes in terrain associated with such moves may heighten energetic costs and effect the decline of populations in new localities. Methods To examine locomotor costs of a carnivorous mammal moving in mountainous habitats, the oxygen consumption of captive pumas (Puma concolor) was measured during treadmill locomotion on level and incline...

Native and invasive squirrels show different behavioural responses to scent of a shared native predator

Joshua Twining, Ian Montgomery, Hansjoerg Kunc, Lilly Price & David Tosh
Invasive species pose a serious threat to native species. In Europe, invasive grey squirrels (Sciurus carolinensis) have replaced native red squirrels (Sciurus vulgaris) in locations across Britain, Ireland and Italy. The European pine marten (Martes martes) can reverse the replacement of red squirrels by grey squirrels, but the underlying mechanism of how pine martens suppress grey squirrels is little understood. Research suggests the reversal process is driven by direct predation, but why the native red...

Data from: Using structured eradication feasibility assessment to prioritise the management of new and emerging invasive alien species in Europe

Olaf Booy, Peter A. Robertson, Niall Moore, Jess Ward, Helen E. Roy, Tim Adriaens, Richard Shaw, Johan Van Valkenburg, Gabe Wyn, Sandro Bertolino, Olivier Blight, Etienne Branquart, Giuseppe Brundu, Joe Caffrey, Dario Capizzi, Jim Casaer, Olivier De Clerck, Neil Coughlan, Eithne Davis, Jaimie Dick, Franz Essl, Guillaume Fried, Piero Genovesi, Pablo González-Moreno, Frank Hysentruyt … & Aileen C. Mill
Prioritising the management of invasive alien species (IAS) is of global importance and within Europe integral to the EU IAS regulation. To prioritise management effectively the risks posed by IAS need to be assessed, but so too does the feasibility of their management. While risk of IAS to the EU has been assessed, the feasibility of management has not. We assessed the feasibility of eradicating 60 new (not yet established) and 35 emerging (established with...

Data from: Influence of intra- and interspecific variation in predator-prey body size ratios on trophic interaction strengths

Ross N. Cuthbert, Ryan J. Wasserman, Tatenda Dalu, Horst Kaiser, Olaf L. F. Weyl, Jaimie T. A. Dick, Arnaud Sentis, Mike W. McCoy & Mhairi E. Alexander
1. Predation is a pervasive force that structures food webs and directly influences ecosystem functioning. The relative body sizes of predators and prey may be an important determinant of interaction strengths. However, studies quantifying the combined influence of intra- and interspecific variation in predator-prey body size ratios are lacking. 2. We use a comparative functional response approach to examine interaction strengths between three size classes of invasive bluegill and largemouth bass towards three scaled size...

Data from: Microplastics disrupt hermit crab shell selection

Andrew Crump, Charlotte Mullens, Emily Bethell, Eoghan Cunningham & Gareth Arnott
Microplastics (plastics < 5 mm) are a potential threat to marine biodiversity. However, the effects of microplastic pollution on animal behaviour and cognition are poorly understood. We used shell selection in common European hermit crabs (Pagurus bernhardus) as a model to test whether microplastic exposure impacts the essential survival behaviours of contacting, investigating, and entering an optimal shell. We kept 64 female hermit crabs in tanks containing either polyethylene spheres (n = 35) or no...

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...

A global analysis of enemy release and its variation with latitude

Meng Xu, Xidong Mu, Shuang Zhang, Jaimie Dick, Bingtao Zhu, Dangen Gu, Yexin Yang, Du Luo & Yinchang Hu
Aim: The enemy release hypothesis (ERH) posits that exotic species suffer lower enemy damage than natives, and thus promotes their successful invasion. However, the generality of lower damage for exotics remains widely debated. A recent view proposes that enemy release (ER) could systematically change with latitude, potentially helping explain these inconsistencies. Here, we test whether exotic plant species suffer consistently lower herbivore damage relative to natives, and whether ER varies with latitude. Location: Global. Time...
