Data from: Prey encounters and spatial memory influence use of foraging patches in a marine central place forager

Virginia Iorio-Merlo, Isla M. Graham, Rebecca C. Hewitt, Geert Aarts, Enrico Pirotta, Gordon D. Hastie & Paul M. Thompson
Given the patchiness and long-term predictability of marine resources, memory of high-quality foraging grounds is expected to provide fitness advantages for central place foragers. However, it remains challenging to characterise how marine predators integrate memory with recent prey encounters to adjust fine-scale movement and use of foraging patches. Here, we used two months of movement data from harbour seals (Phoca vitulina) to quantify the repeatability in foraging patches as a proxy for memory. We then...

Variation and correlation in the timing of breeding of North Atlantic seabirds across multiple scales

Katharine Keogan, Francis Daunt, Sarah Wanless, Richard Phillips, David Alvarez, Tycho Anker-Nilssen, Robert Barrett, Claus Bech, Peter Becker, Per-Arvid Berglund, Sandra Bouwhuis, Zofia Burr, Olivier Chastel, Signe Christensen-Dalsgaard, Sébastien Descamps, Tony Diamond, Kyle Elliott, Kjell Einar Erikstad, Mike Harris, Jonas Hentati-Sundberg, Martin Heubeck, Magdalene Langset, Svein Lorentsen, Heather Major, Mark Mallory … & Stephen Kress
Timing of breeding, an important driver of fitness in many populations, is widely studied in the context of global change, yet despite considerable efforts to identify environmental drivers of seabird nesting phenology, for most populations we lack evidence of strong drivers. Here we adopt an alternative approach, examining the degree to which different populations positively covary in their annual phenology to infer whether phenological responses to environmental drivers are likely to be (i) shared across...

Differential nutrient limitation and tree height control leaf physiology, supporting niche partitioning in tropical dipterocarp forests

David Bartholomew, Lindsay Banin, Paulo Bittencourt, Mohammed Aminur Bin Suis, Lina Mercado, Reuben Nilus, David Burslem & Lucy Rowland
Revealing the mechanisms of environmental niche partitioning within lowland tropical forests is important for understanding the drivers of current species distributions and potential vulnerability to environmental change. Tropical forest structure and species composition change across edaphic gradients in Borneo over short distances. However, our understanding of how edaphic conditions affect tree physiology and whether these relationships drive niche partitioning within Bornean forests remains incomplete. This study evaluated how leaf physiological function changes with nutrient availability...

Figure data and analysis for: The effect of grain size on porewater radiolysis

Joel DeWitt, Sean McMahon & John Parnell
The radiolysis of porewaters by uranium, thorium, and potassium in mineral grains is a recognised source of molecular hydrogen in rock- and sediment-hosted fluids. This radiolytic hydrogen is of geomicrobiological interest as a potential energy source (electron donor) for microbial metabolism, especially in energy-limited settings such as the marine deep biosphere or the subsurface of Mars. Previous efforts to predict the production of radiolytic hydrogen from columns of rock and sediment have tended to rely...

Tony Kess, J. Brian Dempson, Sarah J. Lehnert, Kara Layton, Anthony Einfeldt, Paul Bentzen, Sarah Salisbury, Amber Messmer, Steven Duffy, Daniel Ruzzante, Cameron Nugent, Moira Ferguson, Jong Leong, Ben Koop, Michael O'Connell, Ian Bradbury, Kara K. S. Layton, Sarah J. Salisbury, Amber M. Messmer, Daniel E. Ruzzante, Cameron M. Nugent, Moira M. Ferguson, Jong S. Leong, Ben F. Koop, Michael F. O’Connell … & Ian R. Bradbury
Colonization of extreme habitats requires extensive adaptation to novel environmental challenges. Deep-water environments (>50 m) have high hydrostatic pressure, low temperature, and low light, requiring physiological and visual system adaptation, but genomic mechanisms underlying evolution in these environments are rarely known. Post-glacial colonization of Gander Lake in Newfoundland, Canada, by Arctic Charr (Salvelinus alpinus) provides the opportunity to study the genomic basis of adaptation to extreme deep-water environments. Here, we compare genomic and morphometric divergence...

Effects of temperature on mating behaviour and mating success: a meta-analysis

Natalie Pilakouta & Anais Baillet
In light of global climate change, there is a pressing need to understand how populations will respond to rising temperatures. Understanding the effects of temperature changes on mating behaviour is particularly important, given its implications for population viability. To this end, we performed a meta-analysis of 53 studies to examine how temperature changes influence mating latency, choosiness, and mating success. We hypothesized that if higher temperatures make mate searching and mate assessment more costly due...

Data from: Land-based climate solutions for the United States

G. Philip Robertson, Stephen Hamilton, Keith Paustian & Pete Smith
Meeting end-of-century global warming targets requires aggressive action on multiple fronts. Recent reports note the futility of addressing mitigation goals without fully engaging the agricultural sector, yet no available assessments combine both nature-based solutions (reforestation, grassland and wetland protection, and agricultural practice change) and cellulosic bioenergy for a single geographic region. Collectively, these solutions might offer a suite of climate, biodiversity, and other benefits greater than either alone. Nature-based solutions are largely constrained by the...

Interspecific coprophagia by wild red foxes: DNA metabarcoding reveals a potentially widespread form of commensalism among animals

Cristian D. Navarro Waggershauser, Pierre Taberlet, Eric Coissac, Kenny Kortland, Catherine Hambly & Xavier Lambin
Vertebrate animals are known to consume other species’ faeces, yet the role of such coprophagy in species dynamics remains unknown, not least due to the methodological challenges of documenting it. In a large-scale metabarcoding study of red fox and pine marten scats, we document a high occurrence of domestic dog DNA in red fox scats and investigate if it can be attributed to interspecific coprophagia. We tested whether experimental artifacts or other sources of DNA...

Ecosystems...

Spatiotemporal connectivity dynamics in spatially structured populations

Joseph Drake, Xavier Lambin & Chris Sutherland
Connectivity is a fundamental concept linking dispersal to the emergent dynamics and persistence of spatially structured populations. Functional measures of connectivity typically seek to integrate aspects of landscape structure and animal movement to describe ecologically meaningful connectedness at the landscape and population scale. Despite this focus on function, traditional measures of landscape connectivity assume it is a static property of the landscape, hence abstracting out the underlying spatiotemporal population dynamics. Connectivity is, arguably, a dynamic...

Observation‐based global soil heterotrophic respiration indicates underestimated turnover and sequestration of soil carbon by terrestrial ecosystem models

Yue He, Jinzhi Ding, Tsechoe Dorji, Tao Wang, Juan Li & Pete Smith
Soil heterotrophic respiration (Rh) refers to the flux of CO2 released from soil to atmosphere as a result of organic matter decomposition by soil microbes and fauna. As one of the major fluxes in the global carbon cycle, the estimation of global Rh still exists large uncertainties, which further limited our current understanding of the carbon accumulation in soils. Here, we applied a Random Forest algorithm to create a global dataset of soil Rh, by...

Probing Into the Crust Through eastern Scotland

The PICTS project, standing for Probing Into the Crust Through eastern Scotland, is research to uncover the role that the Highland Boundary Fault (HBF) has played in building Scotland using seismology. Starting in March 2022, we have installed three lines of closely-spaced seismometers for 12 months across the HBF in eastern Scotland. The data collected will help us to determine if it marks a major plate boundary, uncover what role it had in the building...

Spy in the sky: a method to identify pregnant small cetaceans

Barbara Cheney, Julian Dale, Paul Thompson & Nicola Quick
Data on sex ratios, age classes, reproductive success and health status are key metrics to manage populations yet can be difficult to collect in wild cetacean populations. Long-term individual-based studies provide a unique opportunity to apply unoccupied aerial system (UAS) photogrammetry to non-invasively measure body morphometrics of individuals with known life history information. The aims of this study were 1) to compare length measurements from UAS photogrammetry with laser photogrammetry and 2) to explore whether...

Demographic consequences of heterogeneity in conspecific density dependence among mast fruiting tropical trees

Michael O'Brien & David Burslem
The role of conspecific density dependence (CDD) in the maintenance of species richness is a central focus of tropical forest ecology. However, tests of CDD often ignore the integrated effects of CDD over multiple life-stages and their long-term impacts on population demography. We combined a 10-year time series of seed production, seedling recruitment and sapling and tree demography of three dominant Southeast Asian tree species that adopt a mast fruiting phenology. We used these data...

Reef effect of offshore structures on the occurrence and foraging activity of harbour porpoises

Oihane Fernandez-Betelu, Isla M. Graham & Paul M. Thompson
With increasing numbers of offshore structures to be decommissioned, a better understanding of their effect on marine predators is timely. There is some evidence that oil and gas platforms may attract marine mammals acting as artificial reefs. However, it is unclear whether different man-made structure designs have similar effects. Further, due to the lack of baseline data prior to installation, it is unknown whether artificial structures modify the diel patterns of occurrence and foraging behaviour...

Data from: Hierarchical variation in phenotypic flexibility across timescales and associated survival selection shape the dynamics of partial seasonal migration

Paul Acker, Francis Daunt, Sarah Wanless, Sarah J. Burthe, Mark A. Newell, Michael P. Harris, Carrie Gunn, Robert Swann, Ana Payo-Payo & Jane M. Reid
Population responses to environmental variation ultimately depend on within-individual and among-individual variation in labile phenotypic traits that affect fitness, and resulting episodes of selection. Yet, complex patterns of individual phenotypic variation arising within and between time periods, and associated variation in selection, have not been fully conceptualised or quantified. We highlight how structured patterns of phenotypic variation in dichotomous threshold traits can theoretically arise and experience varying forms of selection, shaping overall phenotypic dynamics. We...
