title: Data from: Hotter nests produce hatchling lizards with lower thermal tolerance

description: In many regions, the frequency and duration of summer heatwaves is
 predicted to increase in future. Hotter summers could result in higher
 temperatures inside lizard nests, potentially exposing embryos to
 thermally stressful conditions during development. Potentially,
 developmentally plastic shifts in thermal tolerance could allow lizards to
 adapt to climate warming. To determine how higher nest temperatures affect
 the thermal tolerance of hatchling geckos, we incubated eggs of the
 rock-dwelling velvet gecko, Amalosia lesueurii, at two fluctuating
 temperature regimes to mimic current nest temperatures (mean 23.2°C, range
 10–33°C, ‘cold’) and future nest temperatures (mean 27.0°C, range 14–37°C,
 ‘hot’). Hatchlings from the hot incubation group hatched 27 days earlier
 and had a lower critical thermal maximum (CTmax 38.7°C) and a higher
 critical thermal minimum (CTmin 6.2°C) than hatchlings from cold
 incubation group (40.2 and 5.7°C, respectively). In the field, hatchlings
 typically settle under rocks near communal nests. During the hatching
 period, rock temperatures ranged from 13 to 59°C, and regularly exceeded
 the CTmax of both hot- and cold-incubated hatchlings. Because rock
 temperatures were so high, the heat tolerance of lizards had little effect
 on their ability to exploit rocks as retreat sites. Instead, the timing of
 hatching dictated whether lizards could exploit rocks as retreat sites;
 that is, cold-incubated lizards that hatched later encountered less
 thermally stressful environments than earlier hatching hot-incubated
 lizards. In conclusion, we found no evidence that CTmax can shift upwards
 in response to higher incubation temperatures, suggesting that hotter
 summers may increase the vulnerability of lizards to climate warming.

title: Data from: Kinship of long-term associates in the highly social sperm whale

description: The evolution of stable social groups can be promoted by both indirect and
 direct fitness benefits. Sperm whales (Physeter macrocephalus) are highly
 social, with a hierarchical social structure based around core groups of
 adult females and sub-adults, a rare level of complexity among mammals. We
 combined long-term satellite tracking (ranging from 11 to 607 days) of 51
 individual sperm whales with genetic kinship analysis to assess the
 pattern of kin associations within and among coherent social units. Unlike
 findings for other species with similar social structure, we find no
 consistent correlation between kinship and association apart from close
 associations between two pairs of first-order relatives. A third pair of
 first order relatives did not associate, and overall the mean relatedness
 was the same within as among social groups. However, social behaviour can
 also be promoted by ecological factors such as resource dispersion. We
 assessed putative foraging behaviour during travel from the satellite
 tracking data, which suggested that prey resources were dispersed and
 unpredictable; a condition that could promote living in groups.

title: Data from: Passive microwave observations of inundation area and the area/stage relation in the Amazon River floodplain

description: Inundation patterns in Amazon River floodplains are revealed by analysis
 of the 37 GHz polarization difference observed by the Scanning
 Multichannel Microwave Radiometer on the Nimbus-7 satellite. Flooded area
 is estimated at monthly intervals for January 1979 through August 1987
 using mixing models that account for the major landscape units with
 distinctive microwave emission characteristics. Results are presented
 separately for 12 longitudinal reaches along the Amazon River main stem in
 Brazil as well as for three major tributaries (the Jurua, Purus and
 Madeira rivers). The total area along the Amazon River main stem that was
 flooded (including both floodplain and open water) varied between 19000
 and 91 000km2. The correlation between flooded area and river stage is
 used to develop a predictive relationship and reconstruct regional
 inundation patterns in the floodplain of the Amazon River main stem over
 the past 94 years of stage records (1903-1996). The mean flooded area
 along the Amazon River during this 94-year period was 46800km2, of which
 the openwater surfaces of river channels and floodplain lakes comprised
 about 20 700km2.

title: Data from: Recurrent hybridisation events between Primula vulgaris, P. veris and P. elatior (Primulaceae, Ericales) challenge the species boundaries: Using molecular markers to re‐evaluate morphological identifications

description: Three Primula species, Primula vulgaris, P. veris and P. elatior, have
 been objects of fascination for gardeners and botanists over several
 centuries. The species are able to hybridise, and where they co-occur,
 hybrids are commonly found. In Denmark, Møns Klint on the island of Møn
 and Købelev Skov on Lolland are examples of localities where all three
 species occur and where the hybrids P. ×digenea, the hybrid between P.
 vulgaris and P. elatior, and P. ×polyantha, the hybrid between P. veris
 and P. vulgaris, can also be found. To investigate relations between the
 species and their hybrids, 168 specimens from 10 geographical locations
 were sampled for genetic analysis using DNA markers and identified based
 on morphological traits, primarily inflorescense structure, the size,
 shape, colour and markings of corolla and leaf basis, leaf blade texture
 and hairiness. After identifying species-specific SNPs in the internal
 transcribed spacer sequence, these were used to resolve species and hybrid
 boundaries and status through a cleaved amplified polymorphic sequence
 assay. Polymorphisms in the chloroplast trnL sequence were used as a
 high-throughput marker and used to determine the maternal parent of
 hybrids. Ten simple sequence repeat markers were applied to obtain further
 insight into the genetic makeup of the accessions using Structure and
 Introgress, providing information of genetic variability within and
 between populations. Data analyses indicated that backcrossing of P.
 ×digenea hybrids with parental species has occurred, and that many of the
 P. ×digenea found in the study were later-generation hybrids rather than
 F1s. Analyses of P. ×polyantha specimens show mostly the expected pattern
 for primary hybrids but indications of P. veris ancestry of a P. vulgaris
 plant was discovered. Our results further indicate that some of the
 specimens initially identified as P. elatior include P. vulgaris among
 their progenitors and thus challenge currently accepted species
 boundaries.

title: Data from: Daphniid zooplankton assemblage shifts in response to eutrophication and metal contamination during the Anthropocene

description: Human activities during the Anthropocene result in habitat degradation
 that has been associated with biodiversity loss and taxonomic
 homogenization of ecological communities. Here we estimated effects of
 eutrophication and heavy metal contamination, separately and in
 combination, in explaining zooplankton species composition during the past
 125–145 years using analysis of daphniid diapausing egg banks from four
 lakes in the northeastern USA. We then examined how these community shifts
 influenced patterns of diversity and homogenization. Analysis of past lake
 production (via subfossil pigments) and metal contamination (via
 sedimentary metals) demonstrated that eutrophication alone (19–39%) and in
 combination with metal pollution (17–54%) explained 36–79% of historical
 variation in daphniid species relative abundances in heavily fertilized
 lakes. In contrast, metal pollution alone explained the majority (72%) of
 historical variation in daphniid assemblages at the oligotrophic site.
 Several species colonization events in eutrophying lakes resulted in
 increased species richness and gamma diversity through time. At the same
 time, daphniid assemblages in three eutrophied lakes became more similar
 to each other (homogenized), but this pattern was only seen when
 accounting for species presence/absence. We did not observe consistent
 patterns of divergence between the assemblages in the eutrophying lakes
 and the low-nutrient reference site. Given the pervasive nature of
 fertilization and metal pollution, and the sensitivity of cladocerans to
 these factors, we suggest that many inhabited lake districts may already
 exhibit similar patterns of daphniid assemblage shifts.

title: Data from: How integrated are behavioural and endocrine stress response traits? A repeated measures approach to testing the stress coping style model

description: It is widely expected that physiological and behavioral stress responses
 will be integrated within divergent stress-coping styles (SCS) and that
 these may represent opposite ends of a continuously varying
 reactive–proactive axis. If such a model is valid, then stress response
 traits should be repeatable and physiological and behavioral responses
 should also change in an integrated manner along a major axis of
 among-individual variation. While there is some evidence of association
 between endocrine and behavioral stress response traits, few studies
 incorporate repeated observations of both. To test this model, we use a
 multivariate, repeated measures approach in a captive-bred population of
 Xiphophorus birchmanni. We quantify among-individual variation in
 behavioral stress response to an open field trial (OFT) with simulated
 predator attack (SPA) and measure waterborne steroid hormone levels
 (cortisol, 11-ketotestosterone) before and after exposure. Under the mild
 stress stimulus (OFT), (multivariate) behavioral variation among
 individuals was consistent with a strong axis of personality (shy–bold) or
 coping style (reactive–proactive) variation. However, behavioral responses
 to a moderate stressor (SPA) were less repeatable, and robust statistical
 support for repeatable endocrine state over the full sampling period was
 limited to 11-ketotestosterone. Although post hoc analysis suggested
 cortisol expression was repeatable over short time periods, qualitative
 relationships between behavior and glucocorticoid levels were counter to
 our a priori expectations. Thus, while our results clearly show
 among-individual differences in behavioral and endocrine traits associated
 with stress response, the correlation structure between these is not
 consistent with a simple proactive–reactive axis of integrated
 stress-coping style. Additionally, the low repeatability of cortisol
 suggests caution is warranted if single observations (or indeed repeat
 measures over short sampling periods) of glucocorticoid traits are used in
 ecological or evolutionary studies focussed at the individual level.

title: Data from: Influence of damming on anuran species richness in riparian areas: a test of the serial discontinuity concept

description: 1. Almost all large rivers worldwide are fragmented by dams, and their
 impacts have been modelled using the serial discontinuity concept (SDC), a
 series of predictions regarding responses of key biotic and abiotic
 variables. 2. We evaluated the effects of damming on anuran communities
 along a 245-km river corridor by conducting repeated, time-constrained
 anuran calling surveys at 42 locations along the Broad and Pacolet Rivers
 in South Carolina, USA. 3. Using a hierarchical Bayesian analysis, we test
 the biodiversity prediction of the SDC (modified for floodplain rivers) by
 evaluating anuran occupancy and species diversity relative to dams and
 degree of urbanized land-use. 4. The mean response of the anuran community
 indicated that occupancy and species richness were maximized when sites
 were farther downstream from dams. Sites at the farthest distances
 downstream of dams (47.5 km) had an estimated ~ 3 more species than those
 just below dams. Similarly, species-specific occupancy estimates showed a
 trend of higher occupancy downstream from dams. 5. Synthesis and
 applications. Using empirical estimation within the context of a 245-km
 river riparian landscape, our study supports SDC predictions for a
 meandering river. We demonstrate that with increasing distance downstream
 from dams, riparian anuran communities have higher species richness.
 Reduced species richness immediately downstream of dams is likely driven
 by alterations in flow regime that reduce or eliminate flows which sustain
 riparian wetlands that serve as anuran breeding habitat. Therefore, to
 maintain anuran biodiversity, we suggest that flow regulation should be
 managed to ensure water releases inundate riparian wetlands during
 amphibian breeding seasons and aseasonal releases, which can displace
 adults, larvae, and eggs, are avoided. These outcomes could be achieved by
 emulating pre-dam seasonal discharge data, mirroring discharge of an
 undammed tributary within the focal watershed, or by basing real-time flow
 releases on current environmental conditions.

title: Data from: Yield of temperate forage grassland species is either largely resistant or resilient to experimental summer drought

description: Due to climate change, an increasing frequency and severity of drought
 events are expected to impair grassland productivity, particularly of
 intensively managed temperate grasslands. To assess drought impacts, a
 common field experiment to manipulate precipitation was set up at three
 sites (two Swiss and one Irish) using monocultures and mixtures with two
 and four key forage species. Species differed in their functional traits:
 a shallow-rooted non-legume (Lolium perenne L.), a deep-rooted non-legume
 (Cichorium intybus L.), a shallow-rooted legume (Trifolium repens L.) and
 a deep-rooted legume (Trifolium pratense L.). A nine-week summer drought
 was simulated and soil water status and above-ground biomass yield were
 compared to a rainfed control. Based on soil water measurements, the
 drought induced severe stress at both Swiss sites and extreme stress at
 the Irish site. Under severe drought, the legumes were more
 drought-resistant and showed an average change in above-ground biomass
 (CAB, compared to rainfed control) of only -8% and -24% (for the two Swiss
 sites) while the non-legumes had an average CAB of -51% and -68%. However,
 under extreme drought, all species were substantially impaired, with an
 average CAB of -85%. During a six-week post-drought period with adequate
 water supply (Swiss sites), formerly drought-stressed species were highly
 resilient and attained (legumes) or clearly outperformed (non-legumes) the
 yield level of the rainfed controls. As a result, aggregated over the
 drought and the post-drought periods, a negative drought impact was
 largely absent. Significant overyielding by multi-species mixtures was
 evident under rainfed control (+38% predicted CAB across all sites, P
 &lt; 0.05) and persisted under severe drought conditions (+50%, P
 &lt; 0.05). This overyielding was so large that drought-stressed
 mixtures at least attained the same yield as the average of the rainfed
 monocultures. Yields of selected species of intensively managed temperate
 grasslands are either resistant to a single severe drought or are highly
 resilient as soon as soil moisture levels recover after the drought event.
 Combining species in mixtures can compensate for yield reductions caused
 by severe drought and it offers a practical management tool to adapt
 forage production to climate change.

title: Data from: Evaluation of genetic diversity and population structure of five Chinese indigenous donkey breeds using microsatellite markers

description: China had the largest population of raising donkeys in the world, however
 the number of Chinese indigenous donkey decreased dramatically due to the
 increase of agriculture mechanization in the last century. The species has
 still been important in China because of its edible and medical value,
 therefore the survey on its genetic diversity in China is necessary for
 its conservation and utilization. In this study, 15 microsatellite markers
 were used to evaluate genetic diversity and population structure of five
 Chinese indigenous donkey breeds. The mean values of expected
 heterozygosity, allelic richness, and total number of alleles for all the
 tested Chinese donkeys were 0.70, 6.04, and 6.28 respectively, suggesting
 that the genetic diversity of Chinese indigenous donkeys is rich. The
 Bayesian analysis and principal component analysis plot yielded the same
 clustering result, which revealed that Guanzhong donkey was the most
 differentiated breed in all detected samples, and Jinnan (JN) and
 Guangling (GL) were genetically closed together. Additionally, our results
 indicated that the heterozygote deficit was severe in two Chinese
 indigenous donkey breeds (GL and JN), and it warned us that animal
 conservation activities on this species should be considered carefully in
 near future.
