Incorporating effects of age on energy dynamics predicts non-linear maternal allocation patterns in iteroparous animals

Antoine Barreaux, Andrew Higginson, Michael Bonsall & Sinead English
Iteroparous parents face a trade-off between allocating current resources to reproduction versus maximizing survival to produce further offspring. Optimal allocation varies across age, and follows a hump-shaped pattern across diverse taxa, including mammals, birds and invertebrates. This non-linear allocation pattern lacks a general theoretical explanation, potentially because most studies focus on offspring number rather than quality and do not incorporate uncertainty or age-dependence in energy intake or costs. Here, we develop a life history model...

Congyu Yu, Fangbo Qin, Yin Li, Zichuan Qin & Mark Norell
This is a image dataset for deep learning studies. The main dataset comprises labeled CT slices from 3 protoceratopsian dinosaur skulls discovered from the Gobi Desert, Mongolia. The fossil specimens are now in the Division of Paleontology, American Museum of Natural History, New York, NY, USA. Inside the folders named after specimen number (i.e. IGM100-1021), there are six sub-folders comprising labeled or unlabled CT slice images of the specimen from three directions: axial, coronal, and...

Environmental variation and biotic interactions limit adaptation at ecological margins: lessons from rainforest Drosophila and European butterflies

Eleanor K. O'Brien, Greg M. Walter & Jon Bridle
Models of local adaptation to spatially varying selection predict that maximum rates of evolution are determined by the interaction between increased adaptive potential owing to increased genetic variation, and the cost genetic variation brings by reducing population fitness. We discuss existing and new results from our laboratory assays and field transplants of rainforest Drosophila and UK butterflies along environmental gradients, which try to test these predictions in natural populations. Our data suggest that: (i) local...

Data from: Turnover in floral composition explains species diversity and temporal stability in the nectar supply of urban residential gardens

Nicholas Tew, Katherine Baldock, Ian Vaughan, Stephanie Bird & Jane Memmott
Residential gardens are a valuable habitat for insect pollinators worldwide, but differences in individual gardening practices substantially affect their floral composition. It is important to understand how the floral resource supply of gardens varies in both space and time so we can develop evidence-based management recommendations to support pollinator conservation in towns and cities. We surveyed 59 residential gardens in the city of Bristol, UK, at monthly intervals from March to October. For each of...

The functional diversity of marsupial limbs is influenced by both ecology and developmental constraint

Spencer Pevsner, David Grossnickle & Zhe-Xi Luo
Extant marsupials are less ecologically diverse than placentals, and this is reflected by placentals exhibiting a greater diversity of locomotor modes, including powered flight and fully aquatic swimming. One proposed explanation for this discrepancy is that the development of more disparate marsupial forelimbs is prevented by the neonate’s crawl to the pouch, which requires precocious forelimb development for climbing adaptations. To test predictions of this Developmental Constraint Hypothesis, we pursue a comparative morphometric study on...

Geographic and temporal morphological stasis in the latest Cretaceous ammonoid Discoscaphites iris from the U.S. Gulf and Atlantic Coastal Plains

James Witts, Corinne Myers, Matthew Garb, Kayla Irizarry, Ekaterina Larina, Anastasia Rashkova & Neil Landman
We examine temporal and spatial variation in morphology of the ammonoid cephalopod Discoscaphites iris using a large dataset from multiple localities in the Late Cretaceous (Maastrichtian) of the United States Gulf and Atlantic Coastal Plains, spanning a distance of 2000 km along the paleoshoreline. Our results suggest that the fossil record of D. iris is consistent with no within species net accumulation of phyletic evolutionary change across morphological traits or the lifetime of this species....

Data from: Phylogenomics of elongate-bodied Springtails reveals independent transitions from aboveground to belowground habitats in deep time

Daoyuan Yu, Yinhuan Ding, Erik Tihelka, Chenyang Cai, Feng Hu, Manqiang Liu & Feng Zhang
Soil has become a major hotspot of biodiversity studies, yet the pattern and timing of the evolution of soil organisms are poorly known because of the scarcity of palaeontological data. To overcome this limitation, we conducted a genome-based macroevolutionary study of an ancient, diversified, and widespread lineage of soil fauna, the elongate-bodied springtails (class Collembola, order Entomobryomorpha). To build the first robust backbone phylogeny of this previously refractory group, we sampled representatives of major higher...

Accelerating ice loss from peripheral glaciers in North Greenland

Shfaqat Abbas Khan, William Colgan, Thomas A. Neumann, Michiel R. Van Den Broeke, Kelly M. Brunt, Brice Noël, Jonathan L. Bamber, Javed Hassan & Anders A. Bjørk
In recent decades, Greenland’s peripheral glaciers have experienced large-scale mass loss, resulting in a substantial contribution to sea-level rise. Only 4% of Greenland’s ice cover are small peripheral glaciers that are distinct from the ice sheet proper. Despite comprising this relatively small area, these small peripheral glaciers are responsible for 11% of the ice loss associated with Greenland’s recent sea-level rise contribution. Using the satellite laser platforms ICESat and ICESat-2, we estimate that ice loss...

Shifting balances in the weighting of sensory modalities are predicted by divergence in brain morphology in incipient species of Heliconius butterflies

Denise Dalbosco Dell'Aglio, W. Owen McMillan & Stephen Montgomery
Integrating and weighting sensory perception across modalities is crucial to how animals adapt to their environment. Divergence in brain structure is often in sensory processing regions, suggesting that investment reflects ecological needs. Here, we use two parapatric closely related species, Heliconius erato cyrbia and Heliconius himera, to test the hypothesis that divergence in sensory brain regions affects foraging decisions. These butterflies are isolated across an ecological gradient, which is linked to differences in brain morphology,...

Gridded estimates of hourly areal rainfall for Great Britain 1990-2016 [CEH-GEAR1hr] v2

E. Lewis, N. Quinn, S. Blenkinsop, H.J. Fowler, J. Freer, M. Tanguy, O. Hitt, G. Coxon, P. Bates, R. Woods, M. Fry, A. Chevuturi, O. Swain & S.M. White
The dataset contains 1km gridded estimates of hourly rainfall for Great Britain for the period 1990-2016. The estimates are derived by applying the nearest neighbour interpolation method to a national database of hourly raingauge observations collated by Newcastle University and the UK Centre for Ecology & Hydrology (UKCEH). These interpolated hourly estimates were then used to temporally disaggregate the CEH-GEAR daily rainfall dataset. The estimated rainfall on a given hour refers to the rainfall amount...

When should bees be flower constant? An agent-based model highlights the importance of social information and foraging conditions

Lucy Hayes & Christoph Grüter
1. Many bee species show flower constancy, i.e. a tendency to visit flowers of one type during a foraging trip. Flower constancy is important for plant reproduction, but the benefits of constancy to bees are unclear. Social bees, which often use communication about food sources, show particularly strong flower constancy. 2. We aimed to better understand the benefits of flower constancy in social bees and how these benefits depend on foraging conditions. We hypothesised that...

A Triassic crown squamate

David I. Whiteside, Sophie A. V. Chambi-Trowell & Michael J. Benton
Mammals, birds, and squamates (lizards, snakes, and relatives) are key living vertebrates, and thus understanding their evolution underpins important questions in biodiversity science. Whereas the origins of mammals and birds are relatively well understood, the roots of squamates have been obscure. Here, we report a modern-type lizard from the Late Triassic of England [202 million years (Ma)], comprising a partial skeleton, skull, and mandibles. It displays at least 15 unique squamate traits and further shares...

Updates to data versions and analytic methods influence the reproducibility of results from epigenome-wide association studies

Alexandre A. Lussier, Yiwen Zhu, Brooke J. Smith, Andrew J. Simpkin, Andrew D.A.C. Smith, Matthew J. Suderman, Esther Walton, Kerry J. Ressler & Erin C. Dunn
Biomedical research has grown increasingly cooperative through the sharing of consortia-level epigenetic data. Since consortia preprocess data prior to distribution, new processing pipelines can lead to different versions of the same dataset. Similarly, analytic frameworks evolve to incorporate cutting-edge methods and best practices. However, it remains unknown how different data and analytic versions alter the results of epigenome-wide analyses, which could influence the replicability of epigenetic associations. Thus, we assessed the impact of these changes...

Divergence in Heliconius flight behaviour is associated with local adaptation to different forest structures

Denise Dalbosco Dell'Aglio, Sebastián Mena, Rémi Mauxion, W. Owen McMillan & Stephen H. Montgomery
Micro-habitat choice plays a major role in shaping local patterns of biodiversity. In butterflies, stratification in flight height has an important role in maintaining community diversity. The speciation in Heliconius butterflies is often associated with strong assortative mating, but ecological isolation and local adaptation is also considered essential. Despite its presumed importance, the role of behavioural shifts in early stages of speciation in response to differences in habitat structure is yet to be established. Here,...

Effects of future climate change on the forests of Madagascar

Daniel Hending, Marc Holderied, Grainne McCabe & Sam Cotton
Global climate change is continuing to occur at an alarming rate. In addition to increases in global weather extremes, melting of polar ice caps and subsequent sea level-rises, climate change is known to directly impact the life-cycles and ecologies of many animals and plants. Whilst climate change is projected to result in substantial geographic range and habitat contractions for many species in the future, the effects of climate change on many habitats of conservation-concern remain...

DYRK1a inhibitor mediated rescue of Drosophila models of Alzheimer’s disease-Down Syndrome phenotypes

Bangfu Zhu, Tom Parsons, Wenche Stensen, John S. Mjøen Svendsen, Anders Fugelli & James J.L. Hodge
Alzheimer’s disease (AD) is the most common neurodegenerative disease which is becoming increasingly prevalent due to ageing populations resulting in huge social, economic, and health costs to the community. Despite the pathological processing of genes such as Amyloid Precursor Protein (APP) into Amyloid-b and Microtubule Associated Protein Tau (MAPT) gene, into hyperphosphorylated Tau tangles being known for decades, there remains no treatments to halt disease progression. One population with increased risk of AD are people...

Sequence conservation and structural features that are common within TRP channels

Deny Cabezas-Bratesco, Francisco A. McGee, Charlotte Colenso, Kattina Zavala, Danielle Granata, Vincenzo Carnevale, Juan Opazo & Sebastian Brauchi
TRP proteins are a large family of cation-selective channels, surpassed in variety only by voltage-gated potassium channels. Detailed molecular mechanisms governing how membrane voltage, ligand binding, or temperature can induce conformational changes promoting the open state in TRP channels are still a matter of debate. Aiming to unveil distinctive structural features common to the transmembrane domains within the TRP family, we performed phylogenetic reconstruction, sequence statistics, and structural analysis over a large set of TRP...

Data supplement to: Plant proxy evidence for high rainfall and productivity in the eocene of Australia

Tammo Reichgelt, David Greendwood, Sebastian Steinig, John Conran, David Hutchinson, Daniel Lunt, Leonie Scriven & Jiang Zhu
During the early to middle Eocene, a mid-to-high latitudinal position and enhanced hydrological cycle in Australia would have contributed to a wetter and “greener” Australian continent where today arid to semi-arid climates dominate. Here, we revisit 12 Australian plant megafossil sites from the early to middle Eocene to generate temperature, precipitation and seasonality paleoclimate estimates, as well as net primary productivity (NPP) and vegetation type, based on paleobotanical proxies and compare to early Eocene global...

Neuroanatomical shifts mirror patterns of ecological divergence in three diverse clades of mimetic butterflies

J. Benito Wainwright & Stephen H. Montgomery
Microhabitat partitioning in heterogenous environments can support more diverse communities but may expose partitioned species to distinct perceptual challenges. Divergence across microhabitats could therefore lead to local adaptation to contrasting sensory conditions across small spatial scales, but this aspect of community structuring is rarely explored. Diverse communities of ithomiine butterflies provide an example where closely related species partition tropical forests, where shifts in mimetic colouration are tightly associated with shifts in habitat preference. We test...
