title: Body temperature, evaporative water loss and resting metabolic rate data for 12 southern African arid-zone passerines

description: Surface water is a critical resource for many birds inhabiting arid
 regions, but the implications of regular drinking and dependence on
 surface water for the evolution of thermal physiology remain largely
 unexplored. We hypothesized that avian thermoregulation in the heat has
 evolved in tandem with the use of surface water and predicted that a)
 regularly-drinking species have a greater capacity to elevate rates of
 evaporative water loss (EWL) compared to non-drinking species, and b) heat
 tolerance limits are higher among drinking species. To test these
 predictions, we quantified thermoregulatory responses to high air
 temperature (Ta) in 13 species of passerines from the South African arid
 zone and combined these with published values for an additional four
 species. We categorized each species as either: a) water-dependent,
 regularly-drinking, or b) water-independent, occasional-/non-drinking. In
 support of our predictions, both conventional and
 phylogenetically-independent analyses revealed that evaporative scope (the
 ratio of maximum evaporative water loss (EWL) to minimum thermoneutral EWL
 values) during acute heat exposure was significantly higher among drinking
 species. Moreover, evaporative scope was significantly and positively
 related to heat tolerance limits (i.e., maximum air temperature tolerated
 before the onset of severe hyperthermia). These findings offer new
 insights into the coevolution of water dependence, movement ecology and
 thermal physiology in the context of trade-offs between dehydration
 avoidance and resistance to lethal hyperthermia in hot desert habitats.

title: Data from: Resource dispersion and relatedness interact to explain space use in a solitary predator

description: Resource dispersion or kin selection are commonly used to explain animal
 spatial and social organization. Despite this, studies examining
 how these factors interact in wild populations of solitary animals are
 rare. We used 16 years of individual-level spatial and genetic
 data to disentangle how resources and relatedness influence spatial
 organization of a solitary predator, the Eurasian lynx (Lynx lynx). As
 expected, space-use overlap between neighbouring individuals
 increased when food resources were heterogeneous and unpredictably
 distributed (as predicted from resource dispersion) or when neighbours
 were closely related (as predicted from kin selection). However,
 these patterns were highly dependent on each other. Increased spatial
 overlap was restricted to mother-daughter dyads, with this effect only
 occurring in areas and during seasons when prey was clumped and
 irregularly distributed in the landscape.Additionally, full-siblings with
 similar levels of genetic relatedness did not show these patterns,
 suggesting that kin selection is mediated through mother-daughter
 recognition, and is only beneficial under specific resource dispersion
 circumstances. Our results provide key insights into the
 flexibility of spatial organization of solitary animals, and clearly show
 the importance of considering the interaction between resources and
 kinship when assessing animal space use patterns.

title: Phosphorus allocation to and resorption from leaves regulate the residence time of phosphorus in aboveground forest biomass on Mount Kinabalu, Borneo

description: 1. The residence time of phosphorus (P) in trees is a consequence of plant
 adaptation to P deficiency, with longer P residence time on soils with low
 P availability. P residence time has been studied at the leaf or canopy
 level but seldom at the whole-tree level. Whereas P residence time at the
 leaf or canopy level is largely determined by leaf longevity and the
 resorption of P before leaf abscission, P residence time at the whole-tree
 level will also be influenced by differences in P allocation to different
 plant parts because leaves and woody organs have distinct longevities. 2.
 We estimated the residence time of P in aboveground tree biomass (AGB) as
 the ratio of P mass (i.e. leaves plus wood) to the annual flux of P via
 litterfall (i.e. fine litter plus coarse woody debris) for seven tropical
 rain forests with different soil P availabilities on Mount Kinabalu,
 Borneo. We analysed the effects of P allocation to and resorption from
 leaves on P residence time along a soil P gradient. 3. P residence time
 (2.7–9.8 years) was approximately one fifth of biomass residence time
 (AGB/annual litterfall mass; 19.8–48.8 years). This was due to a
 disproportionately greater relative allocation of P to leaves (P mass in
 leaves/P mass in AGB; 0.11–0.46), which had a smaller fraction of biomass
 (leaf biomass/AGB; 0.02–0.05) but a shorter longevity (1.0–1.8 years). 4.
 The relative allocation of P to leaves was often high on low-P soils, and
 P residence time was expected to be short. By contrast, the resorption
 rate of P from leaves was also high on low-P soils, which extended P
 residence time with P deficiency. Consequently, P residence time was
 nearly constant across the forests. 5. The short residence time of P
 relative to biomass indicates that P residence time depends largely on
 relative P allocation among plant organs. Similar P residence times among
 sites were maintained because greater P allocation to leaves on low-P
 soils was effectively offset by higher P-resorption efficiency.

title: Dataset for: Advanced clones of group B1 cycle 5, population B (B1C5) in Oxapampa-Peru

description: Group B1, cycle B1C5 of Population B (fifth cycle of recombination of the pure native Andigena group B1), is the result of a new population improvement strategy in the absence of R genes started at CIP in 1990. The group B1 derives from the primitive cultivars of Solanum tuberosum ssp. andigena, known to be free of R-genes. These clones were planted in a randomized complete block design (RCBD) with 2-4 replicates at Oxapampa, located at 1810 masl in Pasco-Peru in the Eastern mountain ranges facing the Amazon. The trials were established at Oxapampa due to the high disease pressure of late blight in these areas from 2005 to 2006.

title: A basic ddRADseq two-enzyme protocol performs well in herbarium and silica-dried tissues across four genera

description: Premise of the study: The ability to sequence genome-scale data from
 herbarium specimens would allow for the economical development of broad
 datasets with taxonomic and geographic sampling not otherwise possible.
 Here we evaluate the utility of a basic restriction site-associated DNA
 (ddRADseq) protocol with DNAs from four genera extracted from both
 silica-dried and herbarium tissue. Methods: DNAs from Draba, Boechera,
 Solidago, and Ilex were processed with a double-digest restriction-site
 associated DNA sequencing (ddRADseq) protocol. The effects of DNA
 degradation, taxon, and specimen age were assessed. Results: Although
 taxon, preservation method, and specimen age affected data recovery, large
 phylogenetically informative datasets were obtained from the majority of
 the samples. Discussion: These results suggest that herbarium samples can
 be incorporated into ddRADseq project designs, and that specimen age can
 be used as a rapid on-site guide for sample choice. The detailed protocol
 we provide will allow users to pursue herbarium-based RADseq projects that
 minimize expenses associated with fieldwork and sample evaluation.

title: Data from: Reproductives and eggs trigger worker vibration in a subterranean termite

description: In insect societies, the presence of reproductives or eggs has been shown
 to shape several biological traits in the colony members. Social
 interactions are one of these traits, that involve modification of the
 communication system of the entire colony. Many studies described the role
 of chemical compounds and dominance behaviors in the presence of
 reproductive but vibratory behaviors received very few investigations.
 Yet, vibratory behaviors are ideal candidates, particularly for
 subterranean species like termites, as they could be quickly transmitted
 through the substrate and could be very diversified (origin, modulation).
 Here, we investigated whether the presence of reproductives/eggs affects
 the vibratory behavior (body-shaking) of workers in the subterranean
 termite Reticulitermes flavipes. Our results reveal that the presence of
 reproductives or eggs triggers an increase of workers' body-shaking,
 independent of their colony of origin after 24h. We hypothesize that
 vibratory communication could be used to transfer information about the
 presence of reproductives and eggs to the entire colony, suggesting that
 vibratory behaviors could serve as an important yet neglected mediator of
 social regulation.

title: Data from: Association of serum neurofilament light (sNfL) and disease severity in patients with spinocerebellar ataxia type 3

description: Objective: To investigate serum neurofilament light protein
 (sNfL) levels in patients with spinocerebellar ataxia type 3 (SCA3) and to
 determine whether they are associated with disease severity.
 Methods: This cross-sectional study enrolled 185 healthy controls
 and 235 ATXN3 mutation carriers (17 asymptomatic stage, 20 preclinical
 stage, and 198 ataxic stage). We measured sNfL levels with the single
 molecule array (Simoa) platform. Clinical disease severity was assessed
 using the scale of assessment and rating of ataxia (SARA) and the
 inventory of non-ataxia signs (INAS). In a subgroup of 50 ataxic stage
 patients, we further evaluated the gray matter volume and the integrity of
 white matter fibers by magnetic resonance imaging (MRI).
 Results: sNfL concentrations were elevated in asymptomatic,
 preclinical, and ataxic ATXN3 mutation carriers compared to controls
 (12.18 [10.20-13.92], 21.84 [18.37-23.45], 36.06 [30.04-45.90] and 8.24
 [5.92-10.84] pg/mL, median [interquartile range], respectively, P &lt;
 0·001). sNfL correlated with SARA (r=0.406, 95% confidence interval
 0.284-0.515, P &lt; 0.0001) and INAS (r=0.375, 95% confidence interval
 0.250-0.487, P &lt; 0.0001), and remained significant after adjustment
 for age and CAG repeats. In addition, we observed negative correlations of
 the sNfL with gray matter volume in the left precentral gyrus and the left
 paracentral lobule as well as with the mean diffusivity in widespread
 white matter tracts. Conclusion: Our results demonstrate that
 sNfL levels are increased in SCA3 and are associated with clinical disease
 severity, which supports sNfL as a biomarker for disease severity in SCA3.

title: Data from: Does facial hair greying in chimpanzees provide a salient progressive cue of aging?

description: The greying of human head hair is arguably the most salient marker of
 human aging. In wild mammal populations, greying can change with life
 history or environmental factors (e.g., sexual maturity in silverback
 gorillas). Yet, whether humans are unique in our pattern of age-related
 hair depigmentation is unclear. We examined the relationship between
 pigmentation loss in facial hair (greying) to age, population, and sex in
 wild and captive chimpanzees (Pan troglodytes). Digital facial photographs
 representing three chimpanzee populations (N=145; ages 1–60 years) were
 scored for hair greying on a scale of one [~100% pigmented] to six [~0%
 pigmented]. Our data suggest that chimpanzee head and facial hair
 generally greys with age prior to mid-life (~30 years old), but
 afterwards, greying ceases to increase incrementally. Our results
 highlight that chimpanzee pigmentation likely exhibits substantial
 variation between populations, and that both 'grey' and
 pigmented phenotypes exist across various age classes. Thus, chimpanzee
 facial hair greying is unlikely a progressive indicator of age beyond
 mid-life, and thus facial greying in chimpanzees seems different from the
 pattern observed in humans. Whether this reflects neutral differences in
 senescence, or potential differences in selection pressures (e.g. related
 to conspecific communication), is unclear and worthy of more detailed
 examination across populations and taxa.

title: Data from: The future of food from the sea

description: Global food demand is on the rise and serious questions remain about
 whether supply can increase sustainably. Land-based expansion is possible,
 but may exacerbate climate change and biodiversity loss and compromise the
 delivery of other ecosystem services. As food from the sea represents only
 17% of current edible meat production, we ask: How much food can we expect
 the ocean to sustainably produce by 2050? We examine the main
 food-producing sectors in the ocean—wild fisheries, finfish mariculture,
 and bivalve mariculture—to estimate “sustainable supply curves” accounting
 for ecological, economic, regulatory, and technological constraints. We
 then overlay demand scenarios to estimate future food production from the
 sea. We find that under estimated demand shifts and supply scenarios that
 account for policy reform and technology improvements, edible food from
 the sea could increase by 21-44 million metric tons (mmt) (36-75% more
 than today). This represents 12-25% of the estimated increase in all meat
 needed to feed 9.8 billion people by 2050. Increases in all three sectors
 are likely, but are most pronounced for mariculture. While even more
 dramatic supply expansion is technically possible, the ultimate future of
 food from the sea will hinge on policy reforms, technological innovation,
 and the extent of future shifts in demand.

 of Food from the Sea</em> study. The code to run this analysis is

title: Warmer nights offer no respite for a defensive mutualism

description: 1. Ecologically-relevant symbioses are widespread in terrestrial
 arthropods but based on recent findings these specialized interactions are
 likely to be especially vulnerable to climate warming. Importantly,
 empirical data and climate models indicate that warming is occurring
 asynchronously, with nighttime temperatures increasing faster than daytime
 temperatures. Daytime (DTW) and nighttime warming (NTW) may impact
 ectothermic animals and their interactions differently as DTW results in
 greater daily temperature variation and moves organisms nearer to their
 thermal limits, while NTW avoids thermal limits and may relieve
 constraints of cooler nighttime temperatures; a nuance that has largely
 been ignored in the literature. 2. In laboratory experiments, we
 investigated how the timing of warming influences a widespread defensive
 mutualism involving the pea aphid, Acyrthosiphon pisum, and its heritable
 symbiont, Hamiltonella defensa, which protects against an important
 natural enemy, the parasitic wasp Aphidius ervi. 3. Three aphid sublines
 were experimentally created from single aphid genotype susceptible to A.
 ervi: one line infected with a highly protective H. defensa strain
 (APSE-3), one infected with a moderately protective strain (APSE-8), and
 one without any facultative symbiont. We examined aphid fitness in the
 presence and absence of parasitoids and when exposed to an average 2.5°C
 increase occurring across three warming scenarios (nighttime vs. daytime
 vs. uniform) relative to no-warming controls. 4. An increase of 2.5°C, as
 predicted to occur by the IPCC before 2100, was sufficient to disable the
 aphid defensive mutualism regardless of the timing of warming; a
 surprising result given that the daily maxima for control and nighttime
 warming scenarios were identical. We also found that warming negatively
 impacted i) symbiont-mediated interactions between host and parasitoid
 more than symbiont-free ones, ii) species interactions (host-parasitoid)
 more than each participant independently, and iii) aphids more than
 parasitoids even though higher trophic levels are generally predicted to
 be more affected by warming. 5. Here we show that 2.5°C warming,
 regardless of timing, negatively impacted a common microbe-mediated
 defensive mutualism. While this was a lab-based study, results suggest
 that temperature increases predicted in the near-term may disrupt the many
 ecological symbioses present in terrestrial ecosystems. 30-Mar-2020

title: Woody plant subregions of the Amazon forest

description: The Amazon forest covers 7.5 million Km2 in nine countries, hosts 25% of
 the global biodiversity and is a major contributor to the biogeochemical
 and climatic functioning of the Earth system. Despite its global
 importance, a regionalization of the Amazon tree flora is still lacking.
 Clear and data-driven delimitation of subregions is important for
 macroecological studies, to the identification of metacommunities, and is
 a requisite for conservation planning. We aimed at identifying and mapping
 plant species subregions and investigated their relationships with
 environmental, historical, and human correlates. We provide the first
 woody plant regionalization of the entire Amazon forest using a
 data-driven approach based on assemblage composition patterns. We compiled
 data on woody species composition from 301 assemblages based on species
 occurrences. We then used unconstrained ordination, interpolation and
 clustering techniques to identify and map discrete woody subregions.
 Hierarchical clustering analysis was conducted in order to investigate the
 relationships between the identified subregions. We used multinomial
 logistic regression model and deviance partitioning to investigate the
 influence of environmental, historical, and human factors on subregions
 distribution. We identified 13 woody subregions in the entire Amazon
 forest. The hierarchical subregion classification showed a broad
 Andean-Cratonic east-west division. Variation in subregions were explained
 jointly by human factors and spatial structure followed by environmental
 factors and spatial structure combined. Synthesis. Our woody plant
 subregions differed from WWF ecoregions and physiognomic-based maps,
 highlighting the importance of basing regionalizations on taxon-specific
 groups and confirming that vegetation maps should not be used as proxies
 to plant diversity subregions. Our findings also confirm the need for
 multiple and extensive protected areas in the Amazon forest. The relevance
 of current climate factors in our study alerts to a profound impact that
 climate change could have on the spatial organization of the Amazon
 flora.

title: 7,000 years of turnover: historical contingency and human niche construction shape the Caribbean’s Anthropocene biota

description: The human-mediated movement of species across biogeographic
 boundaries—whether intentional or accidental—is dramatically reshaping the
 modern world. Conservation biologists are grappling with the present-day
 effects of these introductions, but humans have in fact been reshaping
 ecosystems and translocating species for millennia. Acknowledging the
 effects of human-mediated species introductions through time is important
 for understanding present-day biodiversity loss, ecosystem functioning,
 and management needs. Here, we present the first database of terrestrial
 vertebrate species introductions spanning the entire anthropogenic history
 of a system. This ~7,000 year Caribbean dataset allows us to assess the
 roles of historical contingency and priority effects in shaping
 present-day conservation outcomes. We analyzed the spatial and temporal
 dynamics of species introductions in the context of cultural practices and
 human population histories spanning Indigenous, colonial, and modern human
 societies. We highlight how serial human colonization contributed to
 habitat modifications and species extinctions that then shaped subsequent
 species introductions by other human groups, altering ecosystem processes
 dramatically. We quantify how the taxonomic and biogeographical diversity
 of species introductions increases over time, reflecting diversifying
 reasons for species introductions. Importantly, we use the record to
 highlight gaps in the archaeological record, ongoing management
 challenges, and research opportunities in today’s Caribbean biota.
description: We compiled a database of terrestrial vertebrate species that were introduced to the Caribbean using existing paleontological, archaeological, and ecological literature. The databse records the species name, place of origin, and the location of the introduced populations (both the specific island and its place within the Bahamas, Greater Antilles, or Lesser Antilles). Due to ambiguity associated with the exact locality of origin, we used broad biogeographic realms (e.g., Neotropics). Where possible, we included the introduction date, number of times a species was introduced to a particular locality, reason for introduction, and whether an introduction was successful. We discuss three distinct periods that loosely correspond to different societies and economic structures: Indigenous societies, colonial societies, and modern societies, and identify relevant cultural and geographic groupings within these periods.
