Importance of melanin-based colouration and environment in shaping intracellular glutathione levels in nestling and adult tawny owls (Strix aluco)

Guillaume Emaresi, Pierre Bize & Alexandre Roulin
Resources allocated in reproduction are traded off against those invested in self-maintenance such as antioxidant response. Glutathione (GSH) is an intracellular antioxidant defence that scavenges reactive oxygen species, the deleterious byproducts of oxygen consumption. Given the role of intracellular GSH in pheomelanogenesis, a trade-off in GSH allocation between resistance to oxidative stress and melanin production may take place. To investigate how intracellular GSH is regulated in differently coloured individuals at the time of reproduction (in...

Spatially explicit models for decision-making in animal conservation and restoration

Damaris Zurell, Christian Koenig, Anne-Kathleen Malchow, Simon Kapitza, Greta Bocedi, Justin Travis & Guillermo Fandos
Models are useful tools for understanding and predicting ecological patterns and processes. Under ongoing climate and biodiversity change, they can greatly facilitate decision-making in conservation and restoration and help designing adequate management strategies for an uncertain future. Here, we review the use of spatially explicit models for decision support and identify key gaps in current modelling in conservation and restoration. Of 650 reviewed publications, 217 publications had a clear management application and were included in...

Species packing and the latitudinal gradient in local beta-diversity

Ke Cao, Richard Condit, Xiangcheng Mi, Lei Chen, Wubing Xu, David F. R. P. Burslem, Chunrong Cai, Min Cao, Li-Wan Chang, Chengjin Chu, Hu Du, Sisira Ediriweera, C. S. V. Gunatilleke, I. U. A. N. Gunatilleke, Zhanqing Hao, Jinbo Li, Guangze Jin, Buhang Li, Yankun Liu, Yide Li, Michael J. O'Brien, Xiujuan Qiao, Hongwei Ni, Guochun Shen, Xihua Wang … & Jens-Christian Svenning
The decline in species richness at higher latitudes is among the most fundamental patterns in ecology. Whether changes in species composition across space (beta-diversity) contribute to this gradient of overall local species richness (gamma diversity) remains hotly debated. Previous studies that failed to resolve the issue suffered from a well-known tendency for small samples in areas with high gamma-diversity to have inflated measures of beta-diversity. We provide here a novel analytical test, using beta-diversity metrics...

Review of Energy Policy 2021

Rob Gross, Mike Bradshaw, Gavin Bridge, Gisa Weszkalnys, Imogen Rattle, Peter Taylor, Richard Lowes, Meysam Qadrdan, Jianzhong Wu, Jillian Anable, Nicola Beaumont, Astley Hastings, Rob Holland, Andrew Lovett & Anita Shepherd
2021 has been a landmark year for UK energy and climate policy. Plans and strategies were announced across many sectors, from offshore wind to how we heat our homes. The UK also hosted COP26 and pressed hard for greater ambition. Now that the spotlight has moved, in this Review, we consider whether plans will be adequate to deliver results. With a focus on gas and the UK continental shelf, industrial decarbonisation, heat, mobility and the...

Lethal interactions among forest-grouse predators are numerous, motivated by hunger and carcasses, and their impacts determined by the demographic value of the victims

Cristian D. Navarro Waggershauser, Lise Ruffino, Kenny Kortland & Xavier Lambin
New vertebrate communities are emerging in Europe following the recovery of multiple native predators to highly anthropized landscapes where predator control is still prevalent. While the lack of reference points for these communities creates novel challenges for conservationists and wildlife managers, they also provide opportunities to further our understanding of species interactions. Despite a growing body of evidence, many aspects of interactions among predators remain poorly understood, impairing our ability to anticipate the effects of...

Determinants of heart rate in Svalbard reindeer reveal mechanisms of seasonal energy management

L. Monica Trondrud, Gabriel Pigeon, Steve Albon, Walter Arnold, Alina L. Evans, R. Justin Irvine, Elżbieta Król, Erik Ropstad, Audun Stien, Vebjørn Veiberg, John R. Speakman & Leif Egil Loe
Seasonal energetic challenges may constrain an animal’s ability to respond to changing individual and environmental conditions. Here we investigated variation in heart rate, a well-established proxy for metabolic rate, in Svalbard reindeer, a species with strong seasonal changes in foraging and metabolic activity. In 19 adult females we recorded heart rate, subcutaneous temperature and activity using biologgers. Mean heart rate more than doubled from winter to summer. Typical drivers of energy expenditure, such as reproduction...

Seasonal release from competition explains partial migration in European moose

Bram Van Moorter, Navinder Singh, Christer Rolandsen, Erling Solberg, Holger Dettki, Jyrki Pusenius, Johan Månsson, Hakan Sand, Jos Milner, Ole Roer, Aimee Tallian, Wiebke Neumann, Göran Ericsson & Atle Mysterud
Partial migration, whereby a proportion of a population migrates between distinct seasonal ranges, is common throughout the animal kingdom. However, studies linking existing theoretical models of migration probability, with empirical data are lacking. The competitive release hypothesis for partial migration predicts that due to density-dependent habitat selection, the proportion of migrants increases as the relative quality and size of the seasonal range increases, but decreases with increasing migration cost and population density. To test this...

Fat storage influences fasting endurance more than body size in an ungulate

L. Monica Trondrud, Gabriel Pigeon, Elżbieta Król, Steve Albon, Alina L. Evans, Walter Arnold, Catherine Hambly, R. Justin Irvine, Erik Ropstad, Audun Stien, Vebjørn Veiberg, John R. Speakman & Leif Egil Loe
1. The fasting endurance hypothesis (FEH) predicts strong selection for large body size in mammals living in environments where food supply is interrupted over prolonged periods of time. The Arctic is a highly seasonal and food restricted environment, but contrary to predictions from the FEH, empirical evidence shows that Arctic mammals are often smaller than their temperate conspecifics. Intraspecific studies integrating physiology and behaviour of different-sized individuals, may shed light on this paradox. 2. We...

Social selection is density dependent but makes little contribution to total selection in New Zealand giraffe weevils

David Fisher, Rebecca Le Grice & Christina Painting
Social selection occurs when traits of interaction partners influence an individual’s fitness and can alter total selection strength. However, we have little idea of what factors influence social selection’s strength. Further, social selection only contributes to overall selection when there is phenotypic assortment, but simultaneous estimates of social selection and phenotypic assortment are rare. Here we estimated social selection on body size in a wild population of New Zealand giraffe weevils (Lasiorhynchus barbicornis). We measured...

Broad-Scale Responses of Harbor Porpoises to Pile-Driving and Vessel Activities During Offshore Windfarm Construction

Aude Benhemma-Le Gall, Isla Graham, Nathan Merchant & Paul Thompson
Offshore windfarm developments are expanding, requiring assessment and mitigation of impacts on protected species. Typically, assessments of impacts on marine mammals have focussed on pile-driving, as intense impulsive noise elicits adverse behavioural responses. However, other construction activities such as jacket and turbine installation also change acoustic habitats through increased vessel activity. To date, the contribution of construction-related vessel activity in shaping marine mammal behavioural responses at windfarm construction sites has been overlooked and no guidelines...

Population and seascape genomics of a critically endangered benthic elasmobranch, the blue skate Dipturus batis

Aurelien Delaval, Michelle Frost, Victoria Bendall, Stuart Hetherington, David Stirling, Galice Hoarau, Catherine Jones & Leslie Noble
The blue skate (Dipturus batis) has a patchy distribution across the North-East Atlantic Ocean, largely restricted to occidental seas around the British Isles following fisheries-induced population declines and extirpations. The viability of remnant populations remains uncertain, and could be impacted by continued fishing and bycatch pressure and the projected impacts of climate change. We genotyped 503 samples of D. batis, obtained opportunistically from the widest available geographic range, across 6,350 single nucleotide polymorphisms (SNPs) using...

The value of considering demographic contributions to connectivity - a review

Joseph Drake, Xavier Lambin & Christopher Sutherland
Connectivity is a central concept in ecology, wildlife management and conservation science. Understanding the role of connectivity in determining species persistence is increasingly important in the face of escalating anthropogenic impacts on climate and habitat. These connectivity augmenting processes can severely impact species distributions and community and ecosystem functioning. One general definition of connectivity is an emergent process arising from a set of spatial interdependencies between individuals or populations, and increasingly realistic representations of connectivity...

Latitudinal clines in sexual selection, sexual size dimorphism, and sex-specific genetic dispersal during a poleward range expansion

Rachael Dudaniec, Alexander Carey, Erik Svensson, Bengt Hansson, Chuan Ji Yong & Lesley Lancaster
Range expansions can be shaped by sex differences in behaviours and other phenotypic traits affecting dispersal and reproduction. Here, we investigate sex differences in morphology, behaviour and genomic population differentiation along a climate-mediated range expansion in the common bluetail damselfly Ischnura elegans in northern Europe. We sampled 65 sites along a 583 km gradient spanning the I. elegans range in Sweden and quantified latitudinal gradients in site relative abundance, sex ratio and sex-specific shifts in...

Within-year and among-year variation in impacts of targeted conservation management on juvenile survival in a threatened population

Sarah Fenn, Eric Bignal, Sue Bignal, Amanda Trask, Davy McCracken, Pat Monaghan & Jane Reid
1. Overall impacts of targeted conservation interventions on population growth rate (λ) will depend on within-year and among-year variation in exposure of target individuals to interventions, and in intervention efficacy in increasing vital rates of exposed individuals. Juvenile survival is one key vital rate that commonly varies substantially within and among years, and consequently drives variation in λ. However, within-year, among-year and overall impacts of targeted interventions on population-wide survival probabilities of potentially mobile juveniles...
