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...

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...

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...

Ancient geological dynamics impact neutral biodiversity accumulation and are detectable in phylogenetic reconstructions

Leonel Herrera-Alsina, Adam Algar, Greta Bocedi, Cecile Gubry-Rangin, Lesley Lancaster, Poppy Mynard, Owen Osborne, Alexander Papadopulos, Simon Creer, Meis Nangoy, Fahri Fahri, Pungki Lupiyaningdyah, I Made Sudiana, Berry Juliandi & Justin Travis
Aim Landmasses have been continuously modified by tectonic activity, the breakup and collision of landmasses is thought to have generated or suppressed ecological opportunities, altering the rates of speciation, dispersal and extinction. However, the extent to which the signatures of past geologic events are retained in modern biodiversity patterns - or obliterated by recent ecological dynamics - remains unresolved. We aim to identify the fingerprint of different scenarios of geological activity on phylogenetic trees and...

Analysis of independent cohorts of outbred CFW mice reveals novel loci for behavioral and physiological traits and identifies factors determining reproducibility

Jennifer Zou, Shyam Gopalakrishnan, Clarissa Parker, Jerome Nicod, Richard Mott, Na Cai, Arimantas Lionikas, Robert Davies, Abraham Palmer & Jonathan Flint
Combining samples for genetic association is standard practice in human genetic analysis of complex traits, but is rarely undertaken in rodent genetics. Here, using 23 phenotypes and genotypes from two independent laboratories, we obtained a sample size of 3,076 commercially available outbred mice and identified 70 loci, more than double the number of loci identified in the component studies. Fine-mapping in the combined sample reduced the number of likely causal variants, with a median reduction...

Data for: Are immigrants outbred and unrelated? Testing standard assumptions in a wild metapopulation

Lisa Dickel, Peter Arcese, Pirmin Nietlisbach, Lukas Keller & Jane Reid
Immigration into small recipient populations is expected to alleviate inbreeding and increase genetic variation, and hence facilitate population persistence through genetic and/or evolutionary rescue. Such expectations depend on three standard assumptions: that immigrants are outbred, unrelated to existing natives at arrival, and unrelated to each other. These assumptions are rarely explicitly verified, including in key field systems in evolutionary ecology. Yet, they could be violated due to non-random or repeated immigration from adjacent small populations....

Density-by-diet interactions during larval development shape adult life-history trait expression and fitness in a polyphagous fly

Juliano Morimoto
Habitat quality early in life determines individual fitness, with possible long-term evolutionary effects on groups and populations. In holometabolous insects, larval ecology plays a major role in determining the expression of traits in adulthood, but how ecological conditions during larval stage interact to shape adult life-history and fitness, particularly in non-model organisms, remains subject to scrutiny. Consequently, our knowledge of the interactive effects of ecological factors on insect development is limited. Here, using the polyphagous...

Annual measurements of body mass for Adelie penguin chicks prior to fledging at Signy Island, from 1997 to 2020.

Michael J Dunn, Stacey Adlard, Amanda Lynnes, Dirk Briggs, Derren Fox & Tim Morley
This dataset captures annual measurements of body mass for Adelie penguin chicks at Signy Island, from 1997 until 2020. Between 50 and 100 chicks are measured on beaches immediately prior to their departure, with 3-5 weighing sessions carried out annually per species in the period before fledging is complete. This monitoring contributes to the CCAMLR Ecosystem Monitoring Program (CEMP) and is part of the annual seabird Long Term Monitoring Science carried out by the British...

Far-field effects of impulsive noise on coastal bottlenose dolphins

Oihane Fernandez-Betelu, Isla M. Graham, Kate L. Brookes, Barbara J. Cheney, Timoty R. Barton & Paul M. Thompson
Increasing levels of anthropogenic underwater noise have caused concern over their potential impacts on marine life. Offshore renewable energy developments and seismic exploration can produce impulsive noise which is especially hazardous for marine mammals because it can induce auditory damage at shorter distances and behavioural disturbance at longer distances. However, far-field effects of impulsive noise remain poorly understood, causing a high level of uncertainty when predicting the impacts of offshore energy developments on marine mammal...

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...

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...

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...

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...

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 & Cristian N. Waggershauser
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...

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...
