title: Group augmentation on trial: helpers in small groups enhance antipredator defence of eggs

description: Mechanisms selecting for the evolution of cooperative breeding are hotly
 debated. While kin selection theory has been the central paradigm to
 explain the seemingly altruistic behaviour of non-reproducing helpers, it
 is increasingly recognized that direct fitness benefits may be highly
 relevant. The group augmentation hypothesis proposes that alloparental
 care may evolve to enhance group size when larger groups yield increased
 survival and/or reproductive success. However, there is a lack of
 empirical tests. Here we use the cooperatively breeding cichlid fish
 Neolamprologus pulcher, in which group size predicts survival and group
 stability, to test this hypothesis experimentally by prompting two
 cooperative tasks: defence against an egg predator and digging out sand
 from the breeding shelter. We controlled for alternative mechanisms such
 as kin selection, load-lightening and coercion. As predicted by the group
 augmentation hypothesis, helpers increased defence against an egg predator
 in small compared to large groups. This difference was only evident in
 large helpers due to size-specific task specialization. Furthermore,
 helpers showed more digging effort in the breeding chamber compared to
 alternative personal shelters, indicating that digging was an altruistic
 service to the dominant breeders.

title: Experiments on the snowfall, temperature, and humidity to the Arctic summer snowstorm using ocean-ice couple model (POP2-CICE5) with JRA55-do and MERRA2 forcing

description: In the Arctic, short-lived summer snowstorms can provide snow cover that
 can increase surface reflectivity and heat capacity. Despite their
 potential importance, little research has been done to understand the
 impact of summer snowstorms on basin-scale Arctic sea ice cover. Our
 observational analysis shows that a summer snowstorm event is accompanied
 by cyclonic ice drift, increases in surface albedo and surface air cooling
 that can persist for up to ~2 weeks, dampening sea ice loss. Specifically,
 multiple snowstorm events in a summer, on average, results in net increase
 in sea ice extent of ~0.2×106 km2 by early September. Experiments with a
 sophisticated ice-ocean model framework indicate that the initial
 expansion of sea ice extent is driven by cyclonic wind-driven ice drifts
 driving sea ice southwards and increasing albedo around the summer ice
 edge, however the thermal effects from the associated snowfall and
 atmospheric conditions result in a stronger overall impact on
 basin-averaged sea ice extent at seasonal scales. Additional model
 experiments were carried out to isolate the physical processes
 contributing to the thermal response of Arctic sea ice to summer
 snowstorms. Our results show the impact of surface air cooling on sea ice
 extent is about 3.5 times larger than the snowfall/albedo response.
 However, our simulated albedo response is weaker than the observed
 response, likely due to the negligible difference in surface albedo
 between old snow and freshly fallen snow – a limiting factor in our
 analysis and a topic worthy of future focus.

title: Occurence data for species distribution modelling of wild Coffea canephora

description: The assessment of population vulnerability under climate change is crucial
 for planning conservation as well as for ensuring food security. Coffea
 canephora is, in its native habitat, an understory tree that is mainly
 distributed in the lowland rainforests of tropical Africa. Also known as
 Robusta, its commercial value constitutes a significant revenue for many
 human populations in tropical countries. Comparing ecological and genomic
 vulnerabilities within the species’ native range can provide valuable
 insights about habitat loss and the species’ adaptive potential, allowing
 to identify genotypes that may be act as a resource for varietal
 improvement. By applying species distribution models, we assessed
 ecological vulnerability as the decrease in climatic suitability under
 future climatic conditions from 492 occurrences. We then quantified
 genomic vulnerability (or risk of maladaptation) as the allelic
 composition change required to keep pace with predicted climate change.
 Genomic vulnerability was estimated from genomic environmental
 correlations throughout the native range. Suitable habitat was predicted
 to diminish to half its size by 2050, with populations near coastlines and
 around the Congo River being the most vulnerable. Whole-genome sequencing
 revealed 165 candidate SNPs associated to climatic adaptation in
 C. canephora, which were located in genes involved in plant
 response to biotic and abiotic stressors. Genomic vulnerability was higher
 for populations in West Africa and in the region at the border between DRC
 and Uganda. Despite an overall low correlation between genomic and
 ecological vulnerability at broad scale, these two components of
 vulnerability overlap spatially in ways that may become damaging. Genomic
 vulnerability was estimated to be 23% higher in populations where habitat
 will be lost in 2050 compared to regions where habitat will remain
 suitable. These results highlight how ecological and genomic
 vulnerabilities are relevant when planning on how to cope with climate
 change regarding an economically important species.
description: <em>Coffea canephora</em> is a self-incompatible evergreen tree species
 which likely originates from the sub-equatorial lowland rainforests of
 Africa (Berthaud, 1986; Davis et al., 2006). The species is distributed in
 the understory of evergreen and semi-deciduous tropical rainforests of the
 Guineo-Congolian region (Gomez et al., 2009). Wild populations of
 <em>C. canephora</em> are found as distant patches of few
 individuals, generally consisting of the parents and offspring scattered
 up to a few kilometres (Berthaud, 1986).
 Combining all known georeferenced data from
 seven herbaria and two living collections, we obtained a total of 526
 carefully checked occurrence records covering the entire range known for
 wild <em>C. canephora</em>.

title: No apparent trade-off between the quality of nest grown feathers and time spent in the nest in an aerial insectivore, the tree swallow

description: Life history theory provides a framework for understanding how trade-offs
 generate negative trait associations. Among nestling birds, time spent in
 the nest, risk of predation, and lifespan covary, but some associations
 are only found within species while others are only observed between
 species. A recent comparative study suggests that allocation trade-offs
 may be alleviated by disinvestment in ephemeral traits, such as nest-grown
 feathers, that are quickly replaced. However, direct resource allocation
 trade-offs cannot be inferred from inter-specific trait-associations
 without complementary intra-specific studies. Here, we asked whether there
 is evidence for a within-species allocation trade-off between feather
 quality and time spent in the nest in tree swallows (Tachycineta bicolor).
 Consistent with the idea that ephemeral traits are deprioritized,
 nest-grown feathers had lower barb density than adult feathers. However,
 despite substantial variation in fledging age among nestlings, there was
 no evidence for a negative association between time in the nest and
 feather quality. Furthermore, accounting for differences in resource
 availability by considering provisioning rate and a nest predation
 treatment did not reveal a trade-off that was masked by variation in
 resources. Our results are most consistent with the idea that the
 inter-specific association between development and feather quality arises
 from adaptive specialization, rather than from a direct allocation
 trade-off.

title: Data for: Assessing the Cognition of Movement Trajectory Visualizations: Interpreting Speed and Direction

description: This paper evaluates cognitively plausible geovisualization techniques for
 mapping movement data. With the widespread increase in the availability
 and quality of space-time data capturing movement trajectories of
 individuals, meaningful representations are needed to properly visualize
 and communicate trajectory data and complex movement patterns using
 geographic displays. Many visualization and visual analytics approaches
 have been proposed to map movement trajectories (e.g. space-time paths,
 animations, trajectory lines, etc.). However, little is known about how
 effective these complex visualizations are in capturing important aspects
 of movement data. Given the complexity of movement data which involves
 space, time, and context dimensions, it is essential to evaluate the
 communicative efficiency and efficacy of various visualization forms in
 helping people understand movement data. This study assesses the
 effectiveness of static and dynamic movement displays as well as visual
 variables in communicating movement parameters along trajectories, such as
 speed and direction. To do so, a web-based survey is conducted to evaluate
 the understanding of movement visualizations by a non-specialist audience.
 This and future studies contribute fundamental insights into the cognition
 of movement visualizations and inspire new methods for the empirical
 evaluation of geovisualizations. 
description: The movement visualization files used in the study were generated
 using the DynamoVis desktop software, available on Github: https://github.com/move-ucsb/DynamoVis Static visualizations were generated as exported screenshots from the software. Dynamic visualizations were generated as exported videos from the software (animated screenshots). Both types of visualizations were created using the built-in export features of DynamoVis. After export, images and videos were edited to add further contextual information, including start and stop icons on the static images, as well as scale bars on all visualizations for contextual information. The survey study design and data collection and analysis methods are described in the associated manuscript. A copy of the survey instrument and an anonymized survey report are included in the data folder.

title: CCMI nursery coral disease 2019

description: Marine infectious diseases are a leading cause of population declines
 globally due, in large part, to challenges in diagnosis and limited
 treatment options. Mitigating disease spread is particularly important for
 species targeted for conservation. In some systems, the strategic
 arrangement of organisms in space can constrain disease outbreaks,
 however, this approach has not been used in marine restoration.
 Reef-building corals have been particularly devastated by disease and
 continue to experience catastrophic population declines. Here, we
 opportunistically tracked white band disease in Acropora cervicornis as it
 moved through a coral nursery in Little Cayman, CI. We show mixtures of
 genotypes led to less prevalence of disease in nursery-reared Acropora
 cervicornis compared to corals on single genotype frames.  
description: The data were collected by divers in the CCMI nursery visually
 assessing each <em>Acropora</em>
 <em>cervicornis</em> colony present on PVC frames. Corals were
 considered Healthy (H) if no signs of the disease were present, diseased
 (X) if any disease was present, Dead - if there was no tissue left (D).
 Corals are on different frames and arranged by column and row. The coral
 ID is the colony's unique identifier.

title: Large Herbivore Nemabiomes: Patterns of Diversity and Sharing

description: Amidst global shifts in the distribution and abundance of wildlife and
 livestock, we have only a rudimentary understanding of ungulate parasite
 communities and parasite-sharing patterns. We used qPCR and DNA
 metabarcoding of fecal samples to characterize gastrointestinal nematode
 (Strongylida) community composition and sharing among 17 sympatric species
 of wild and domestic large mammalian herbivore in central Kenya. We tested
 a suite of hypothesis-driven predictions about the role of host traits and
 phylogenetic relatedness in describing parasite infections. Host species
 identity explained 27-53% of individual variation in parasite prevalence,
 richness, community composition, and phylogenetic diversity. Host and
 parasite phylogenies were congruent, host gut morphology predicted
 parasite community composition and prevalence, and hosts with low
 evolutionary distinctiveness were centrally positioned in the
 parasite-sharing network. We found no evidence that host body size,
 social-group size, or feeding height were correlated with parasite
 composition. Our results reflect the interwoven evolutionary and
 ecological histories of large herbivores and their gastrointestinal
 nematodes and suggest that host identity, phylogeny, and gut
 architecture—a phylogenetically conserved trait related to parasite
 habitat—are the overriding influences on parasite communities. These
 findings have implications for wildlife management and conservation as
 wild herbivores are increasingly replaced by livestock.

 samples from a community of large mammalian herbivores in

title: An Infrasound Array Study of Mount St. Helens

description: The ongoing activity of Mount St. Helens provides an opportunity to study
 the infrasonic wavefield produced by an active, silica-rich volcano. In
 late October 2004, as a pilot experiment for the Acoustic Surveillance for
 Hazardous Eruptions (ASHE) project, we deployed two infrasound arrays,
 each co-located with a broadband seismometer and weather station, to
 continuously record seismo-acoustic signals from Mount St. Helens. The
 nearest array, Coldwater, was deployed on the northern flank of the
 volcano, ∼13 km from the summit. The second array, Sacajawea, was deployed
 ∼250 km east of the volcano, at a distance where stratospherically ducted
 acoustic waves may be expected during the winter. This paper presents an
 overview of the experimental setup, and preliminary results from this
 unique data set. Eruptions on January 16th 2005 and March 9th 2005
 produced strong infrasonic signals. The aseismic January 16th eruption
 signal lasted ∼9.4 min beginning at ∼11:20:44 01/16/05 UTC, while the
 March 9th eruption signal lasted ∼52.8 min beginning at ∼01:26:17 03/09/05
 UTC, with the main steam and ash venting stage probably lasting ∼7.2 min.
 The March 9th signal was an order of magnitude larger than the January
 16th signal, and was clearly recorded 250 km east at the Sacajawea array.
 Infrasonic expressions of long period (LP) seismic events (‘drumbeats’)
 have also been intermittently observed, and are recorded as acoustic waves
 mimicking the waveform and temporal sequence of their seismic
 counterparts. These acoustic observations provide important constraints
 for source models of long period events and eruptions.
description: Data are from the 4-element Coldwater array (CDWR, MSH2*) at
 Mount St Helens from November 1-16, 2004 and March 9, 2005 from 1 - 2:30
 UTC. The Coldwater (CDWR) array was located 13 km from
 the summit of Mount St Helens (backazimuth of 153 degrees) and consisted
 of four MB2000 (DASE/Tekelec) broadband aneroid microbarometers arranged
 in a centered triangle with an aperture of ~100 m  and porous hose wind
 noise suppression. The data were sampled at 40 Hz and have a flat response
 from 0.01 to 17 Hz. We refer the reader to Matoza et al (2007) for details
 on the array setup, eruption, and infrasound data analysis.

title: Topographically distinct adaptive landscapes for teeth, skeletons, and size explain the adaptive radiation of Carnivora (Mammalia)

description: Models of adaptive radiation were originally developed to explain the
 early, rapid appearance of distinct modes of life within diversifying
 clades. Phylogenetic tests of this hypothesis have yielded limited support
 for temporally declining rates of phenotypic evolution across diverse
 clades, but the concept of an adaptive landscape that links form to
 fitness, while also crucial to these models, has received more limited
 attention. Using methods that assess the temporal accumulation of
 morphological variation and estimate the topography of the underlying
 adaptive landscape, I found evidence of an early partitioning of
 craniodental morphological variation in Carnivora (Mammalia) that occurs
 on an adaptive landscape with multiple peaks, consistent with classic
 ideas about adaptive radiation. Although strong support for this mode of
 adaptive radiation is present in traits related to diet, its signal is not
 present in body mass data or for traits related to locomotor behavior and
 substrate use. These findings suggest that adaptive radiations may occur
 along some axes of ecomorphological variation without leaving a signal in
 others and that their dynamics are more complex than simple univariate
 tests might suggest.

title: Spatial heterogeneity and environmental predictors of permafrost region soil organic carbon stocks

description: Large stocks of soil organic carbon (SOC) have accumulated in the Northern
 Hemisphere permafrost region, but their current amounts and future fate
 remain uncertain. By analyzing dataset combining &gt;2700 soil
 profiles with environmental variables in a geospatial framework, we
 generated spatially explicit estimates of permafrost-region SOC stocks,
 quantified spatial heterogeneity, and identified key environmental
 predictors. We estimated that 1014+194−175 Pg C are
 stored in the top 3 m of permafrost region soils. The greatest
 uncertainties occurred in circumpolar toe-slope positions and in flat
 areas of the Tibetan region. We found that soil wetness index and
 elevation are the dominant topographic controllers and surface air
 temperature (circumpolar region) and precipitation (Tibetan region) are
 significant climatic controllers of SOC stocks. Our results provide first
 high-resolution geospatial assessment of permafrost region SOC stocks and
 their relationships with environmental factors, which are crucial for
 modeling the response of permafrost affected soils to changing climate.

title: Prolactin and Lutenizing hormone levels during diestrus and proestrus in mice

description: Prolactin secretion patterns are species-specific, variable and influenced
 by multiple factors including circadian and hormonal cues, stress,
 physiological state and reproductive strategy. In nonpregnant females,
 circulating prolactin levels are low; however, during the afternoon of
 proestrus an estradiol-induced prolactin surge coinciding with the
 preovulatory LH surge has been recorded in many (but not all) species. In
 mice, there have been conflicting reports relating to the occurrence and
 timing of this surge. To gain insight into the characteristics of
 circulating prolactin levels during proestrus we have used repeated tail
 tip blood sampling in C57BL/6J and Swiss Webster mice to profile prolactin
 secretion in individual mice. For this study we have measured prolactin
 levels during diestrus and proestrus using an ultra-sensitive prolactin
 ELISA. To establish the relationship between circulating prolactin levels
 and the timing of the LH surge we have simultaneously measured LH levels
 in the same samples via ELISA. In mice circulating prolactin levels in
 proestrus do not follow a classical surge pattern but show prolonged
 elevation which is not tightly linked to the light/dark cycle.
description: Mouse plasma samples were processed from whole blood samples
 obtained by the tail tip sampling method. Full description of sampling
 method used in doi:10.1111/jne.13129 and based on the method described in
 doi:10.1210/en.2011-0253. Prolactin and LH were measured by
 ultra-sensitive ELISA. Intra-assay and inter-assay coefficients of
 variation for both Prolactin and LH were &lt;10% and &lt;15%
 respectively.
description: Proestrus measurements of
 prolactin and LH taken from mice in which an LH surge was not detected
 when tail tip blood sampling was performed were excluded from analysis
 (C57BL/6J n=2, Swiss Webster n=3 excluded).
