title: Data from: Worms and submersed macrophytes reduce methane release and increase nutrient removal in organic sediments

description: We investigated how the co-presence of macrophytes and macroinvertebrates
 in organic substrates lowers methane emissions and nutrient transport, due
 to radial oxygen loss and bioirrigation. Laboratory incubations were
 performed to measure ebullitive methane fluxes and dissolved gas and
 nutrient fluxes from sediments in presence of macrophytes and macrofauna.
description: The experiment was carried out in the laboratory, under
 controlled conditions. Sediment, macrophytes and macroinvertebrates were
 collected in the field and then transported to the laboratory. Sieved
 sediment was transferred to 24 microcosms: 12 were used for ebullition
 measurements and 12 underwent batch incubations for dissolved gas and
 nutrient fluxes measurement. Four treatments (with 6 replicates) were
 tested: bare sediment (S), sediment with oligochaetes (SO), sediment with
 macrophytes (SV) and sediment with oligochaetes and macrophytes
 (SOV).  Half of the microcosms
 (<em>n </em>= 12, 4 treatments x 3 replicates) was provided
 with an underwater system to collect the gas bubbles released from the
 sediments, which consisted in an 8 cm i.d. inverted transparent glass
 funnel maintained vertically 30 cm above the microcosms surface by a glass
 stick; the far end of the funnel fitted a 40-ml glass vial filled with
 water. At time intervals varying between 1-2 days the 12 vials were
 removed from the funnels, maintained upside-down and closed underwater and
 with lids provided with a rubber septum, weighed and replaced with new
 ones. All vials were previously filled with water, closed with lids and
 weighed. The second set of microcosms
 (<em>n</em> = 12) underwent light and dark batch incubations
 on days 1, 5 and 10 for flux measurements at water-sediment interface.
 Incubations were carried out according to the international standard
 protocol reported in Dalsgaard et al. (2000). Shortly before the
 incubation microcosms were included into plexiglass liners (i.d. 8 cm,
 height 30 cm) equipped with a stirring unit. The incubations started when
 all liners were capped with gas-tight lids and lasted two hours to keep
 O<sub>2</sub> concentration within ±20% of the initial value.
 Water samples were collected at the beginning and at the end of the
 incubation from each liner.

title: Fat storage influences fasting endurance more than body size in an ungulate

description: 1. The fasting endurance hypothesis (FEH) predicts strong selection for
 large body size in mammals living in environments where food supply is
 interrupted over prolonged periods of time. The Arctic is a highly
 seasonal and food restricted environment, but contrary to predictions from
 the FEH, empirical evidence shows that Arctic mammals are often smaller
 than their temperate conspecifics. Intraspecific studies integrating
 physiology and behaviour of different-sized individuals, may shed light on
 this paradox. 2. We tested the FEH in free-living Svalbard reindeer
 (Rangifer tarandus platyrhynchus). We measured daily energy expenditure
 (DEE), subcutaneous body temperature (Tsc) and activity levels during the
 late winter in 14 adult females with body masses ranging from 46.3 to 57.8
 kg. Winter energy expenditure (WEE) and fasting endurance (FE) were
 modelled dynamically by combining these data with body composition
 measurements of culled individuals at the onset of winter (14 years, n =
 140) and variation in activity level throughout winter (10 years, n = 70).
 3. Mean DEE was 6.3±0.7 MJ day−1. Lean mass, Tsc and activity had
 significantly positive effects on DEE. Across all 140 individuals, mean FE
 was 85±17 days (range 48–137 days). In contrast to the predictions of the
 FEH, the dominant factor affecting FE was initial fat mass, while body
 mass and FE were not correlated. Furthermore, lean mass and fat mass were
 not correlated. FE was on average 80% (45 days) longer in fat than lean
 individuals of the same size. Reducing activity levels by ~16% or Tsc by
 ~5% increased FE by 7%, and 4%, respectively. 4. Our results fail to
 support the FEH. Rather, we demonstrate that (i) the size of fat reserves
 can be independent of lean mass and body size within a species, (ii)
 ecological and environmental variation influence FE via their effects on
 body composition, and (iii) physiological and behavioural adjustments can
 improve FE within individuals. Altogether, our results suggest that there
 is a selection in Svalbard reindeer to accumulate body fat, rather than to
 grow structurally large.

title: Phylogeny, biogeography, and classification of the elms (Ulmus)

description: A RAD-seq phylogeny is presented for the genus Ulmus, and a revised
 infrageneric classification is given, with keys, descriptions, and range
 maps for the subgenera and sections. The previously accepted
 classification was based on a cpDNA phylogeny, but several well-marked
 clades in the chloroplast phylogeny are not recovered in the RAD-seq
 phylogeny and do not seem to represent valid clades in the organismal
 phylogeny. Ordination and STRUCTURE analysis support a broad
 species concept in Ulmus sect. Foliaceae and demonstrate interspecific
 hybridization in the section. Several sections of the genus are
 disjunct between Asia, Europe, and North America, indicating dispersals
 between the northern continents with inferred dates from ca 20 Ma to ca 3
 Ma. Morphological variation is discussed, and some characters
 previously considered characteristic of Ulmus subg. Oreoptelea (narrowly
 winged achenes, ciliate achene margin) are shared with the unrelated U.
 villosa.

title: Warming and CO2 effects under oligotrophication on temperate phytoplankton communities

description: Eutrophication, global warming, and rising carbon dioxide (CO2) levels are
 the three most prevalent pressures impacting the biosphere. Despite their
 individual effects are well-known, it remains untested how
 oligotrophication (i.e. nutrients reduction) can alter the planktonic
 community responses to warming and elevated CO2 levels. Here, we performed
 an indoor mesocosm experiment to investigate the
 warming × CO2 interaction under a nutrient reduction
 scenario (40%) mediated by an in-lake management strategy (i.e. addition
 of a commercial solid-phase phosphorus sorbent -Phoslock®) on a natural
 freshwater plankton community. Biomass production increased under
 warming × CO2 relative to present-day conditions;
 however, a Phoslock®-mediated oligotrophication reduced such values by
 30–70%. Conversely, the
 warming × CO2 × oligotrophication
 interaction stimulated the photosynthesis by 20% compared to ambient
 nutrient conditions, and matched with higher resource use efficiency (RUE)
 and nutrient demand. Surprisingly, at a group level, we found that the
 multi-stressors scenario increased the photosynthesis in eukaryotes by
 25%, but greatly impaired in cyanobacteria (ca. −25%). This
 higher cyanobacterial sensitivity was coupled with a reduced light
 harvesting efficiency and compensation point. Since Phoslock®-induced
 oligotrophication unmasked a strong negative
 warming × CO2 effect on cyanobacteria, it becomes
 crucial to understand how the interplay between climate change and
 nutrient abatement actions may alter the, ecosystems functioning. With an
 integrative understanding of these processes, policy makers will design
 more appropriate management strategies to improve the ecological status of
 aquatic ecosystems without compromising their ecological attributes and
 functioning.

title: Territoriality in Drosophila: indirect effects and covariance with body mass and metabolic rate

description: Territoriality (i.e., defence of a resource) is the outcome of behavioural
 interactions that can result in selective advantages in many vertebrates
 and invertebrates. Since territoriality is expressed in a social context,
 an individuals’ territoriality may change according to the phenotype of
 the opponents that they are confronted with (termed “indirect effects”).
 Defending a territory may also confer energetic costs to individuals,
 which could be reflected in their standard metabolic rate (SMR), a key
 component of an ectotherms’ energy budget. Here, we measured
 territoriality using dyadic contests, body mass, and SMR using
 flow-through respirometry, twice in each of 192 adult male Drosophila
 melanogaster. Territoriality, body mass, and (whole-animal) SMR were all
 significantly repeatable. However, essentially all the among-individual
 variation in SMR was shared with body mass, as indicated by a very strong
 among-individual correlation (rind) between body mass and SMR. The
 among-individual correlation between territoriality and SMR also tended to
 be positive, suggesting the presence of underlying metabolic costs to
 territoriality. Although indirect effects on territoriality were present
 but weak (accounting for 8.4% of phenotypic variance), indirect effects on
 territoriality were negatively and significantly correlated with body
 mass. This indicates that larger individuals tended to suppress their
 opponents territoriality. Variation among individuals in their ability to
 suppress territoriality in others was not associated with their own
 territoriality or SMR.

title: Microsatellite genotypes for Gambusia marshi

description: 1. The valley of Cuatro Ciénegas in Coahuila, Mexico has the highest
 degree of local endemism of any habitat in North America. Despite the arid
 desert climate, the Cuatro Ciénegas basin harbors an extensive system of
 permanent streams, wetlands, and spring fed pools. 2. Microsatellite loci
 were surveyed to infer genetic diversity and population structure of
 Gambusia marshi, a poeciliid fish endemic to the desert springs of the
 Cuatro Ciénegas basin and its outflow the Río Salado de Nadadores in
 Mexico. 3. The Sierra de San Marcos and long-term isolation have played a
 vital role in shaping the current pattern of phylogeographic structure in
 G. marshi, and Bayesian clustering analysis revealed four genetic
 populations within G. marshi as well as a major east-west division of the
 of the species corresponding to the Sierra de San Marcos. 4. Most sample
 sites exhibited high levels of genetic differentiation, although there is
 evidence for recent gene flow between some of these locations, presumably
 facilitated by irrigation canals. Although all populations exhibit genetic
 differentiation, the population of G. marshi in Poza Anteojo is extremely
 divergent and should be considered as an independent management unit.
description: <i>Gambusia marshi</i> individuals were sampled from
 seven locations in the Cuatro Ciénegas basin and Río Salado drainage of
 Coahuila, Mexico. Total genomic DNA was extracted from a 1-2 mm section of
 fin using the QIAGEN DNeasy blood and tissue extraction kits (QIAGEN,
 Valencia, CA, USA) following the protocol outlined for DNA isolation from
 animal tissues. Polymerase chain reaction (PCR) amplification of
 microsatellite loci was performed using a three-primer method for each
 locus. The 5’ end of the forward primer of each pair was modified by
 adding the sequence tag (5’-AGG GTTTTCCCAGTCACGACGTT-3’). This primer was
 used in conjunction with the unmodified reverse primer and a third primer,
 identical to the tag on the forward primer, but fluorescently
 labeled.

title: Data from: Genetic and morphological disparity are decoupled

description: The last three decades have seen an expansion of morphological disparity
 analyses, which is now routinely indexed alongside species diversity in
 clades. Strikingly, species diversity is often a poor correlate of
 morphological diversity across clades and time bins. Small clades with
 only a handful of species can encompass spectacular morphological
 diversity, whereas species rich groups may be morphologically highly
 conservative and vice versa. Higher morphological disparity should
 ultimately result from changes at the DNA level, and we might expect it to
 be associated with greater divergence between species at the molecular
 level. However, genetic or molecular disparity has never been quantified
 explicitly in a manner analogous to morphological disparity, and its
 possible relationship with both morphological disparity and species
 diversity has never been assessed. To investigate this relationship
 mammals represent an ideal study group, since their diversity is strongly
 heterogeneous across higher clades, there is a well-studied conflict
 between morphological and molecular phylogenetic analyses, and extensive
 genomic data are available for many species. Here, we explore one possible
 interpretation of the concept of genetic disparity, along with indices for
 its quantification. For major mammal subclades, we find a significant
 positive pairwise correlation between genetic disparity inferred from each
 of 9 different genes, suggesting that there is a consistent signal in
 genetic disparity. In marked contrast, we find no significant correlation
 between any indices of genetic and morphological disparity. Our results
 support the notion of genetic disparity as an evolutionary index that
 complements those of morphological disparity and diversity.

title: Standardised site-level trends, mean productivity, and survival for migrant (arid and humid-zone) and resident species breeding across Europe

description: Wildlife conservation policies directed at common and widespread, but
 declining, species are difficult to design and implement effectively, as
 multiple environmental changes are likely to contribute to population
 declines. Conservation actions ultimately aim to influence demographic
 rates, but targeting actions towards feasible improvements in these is
 challenging in widespread species with ranges that encompass a wide range
 of environmental conditions. Across Europe, sharp declines in the
 abundance of migratory landbirds have driven international calls for
 action, but actions that could feasibly contribute to population recovery
 have yet to be identified. Targeted actions to improve conditions on
 poor-quality sites could be an effective approach, but only if local
 conditions consistently influence local demography and hence population
 trends. Using long-term measures of abundance and demography of breeding
 birds at survey sites across Europe, we show that co-occurring species
 with differing migration behaviours have similar directions of local
 population trends and magnitudes of productivity, but not survival rates.
 Targeted actions to boost local productivity within Europe,
 alongside large-scale (non-targeted) environmental protection
 across non-breeding ranges, could therefore help address the urgent need
 to halt migrant landbird declines. Such demographic routes to recovery are
 likely to be increasingly needed to address global wildlife declines.

title: Patterns of Testosterone in Male White-tailed Deer (Odocoileus virginianus): Seasonal and Lifetime Variation

description: Testosterone is strongly associated with the annual development of antlers
 in cervids, but. endocrine research on wild, freely breeding ungulates is
 often done without repeated capture of known-aged individuals. As a
 result, our knowledge on how testosterone fluctuates over the course of a
 lifetime and variation in lifetime patterns among individuals is limited.
 We investigated patterns of testosterone in a freely breeding population
 of white-tailed deer (Odocoileus virginianus) in Alabama, USA that breeds
 in January. Testosterone peaked during the height of the breeding season,
 despite this period occurring approximately two months later than in most
 temperate-region, white-tailed deer populations. Age-related differences
 in testosterone were only prevalent during the breeding season, with bucks
 ≥3.5 years old having greater testosterone (853 ng/dl ±96 SE; P = 0.012)
 than bucks 1.5–2.5 years old (364 ng/dl ±100 SE). Additionally, an
 individual’s testosterone level as a yearling was not positively
 associated with their lifetime maximum testosterone level (P = 0.583), and
 an individual’s mean testosterone level was positively associated with
 lifetime testosterone variation (P &lt; 0.001). To our knowledge our
 study is one of the first to assess how testosterone early in life might
 relate to individual testosterone later in life. We believe these data
 provide insight into lifetime hormonal patterns in cervids, and that these
 patterns may indicate intraspecific variation of lifetime reproductive
 strategies.

title: Empirical tests of habitat selection theory reveal that conspecific density and patch quality, but not habitat amount, drive long-distance immigration in a wild bird

description: Individuals that disperse long distances from their natal site must select
 breeding patches with no prior knowledge of patch suitability. Despite
 decades of theoretical studies examining which cues dispersing individuals
 should use to select breeding patches, few empirical studies have tested
 the predictions of these theories at spatial scales relevant to
 long-distance dispersal in wild animal populations. Here, we use a novel
 assignment model based on multiple intrinsic markers to quantify natal
 dispersal distances of Wood Thrush (Hylocichla mustelina) breeding in
 forest fragments. We show that long-distance natal dispersal in this
 species is more frequent than commonly assumed for songbirds and that
 habitat selection by these individuals is driven by density-dependence and
 patch quality but not the amount of habitat surrounding breeding patches.
 These results represent an important contribution to understanding habitat
 selection by dispersing individuals, especially with regards to
 long-distance dispersal.

title: Allometry constrains the evolution of sexual dimorphism in Drosophila across 33 million years of divergence

description: Sexual dimorphism is widely viewed as adaptive, reflecting the evolution
 of males and females towards divergent fitness optima. Its evolution,
 however, may often be constrained by the shared genetic architecture of
 the sexes, and by allometry. Here, we investigated the evolution of sexual
 size dimorphism, shape dimorphism, and their allometric relationship in
 the wings of 82 taxa in the family Drosophilidae that have been diverging
 for at least 33 million years. Shape dimorphism among species was
 remarkably similar, with males characterized by longer thinner wings than
 females. There was quantitative variation among species, however, in both
 size and shape dimorphism, and evidence that they have adapted to
 different evolutionary optima in different clades on timescales of about
 10 million years. Within species, shape dimorphism was predicted by size,
 and among species, there was a strong relationship between size dimorphism
 and shape dimorphism. Allometry constrained the evolution of shape
 dimorphism for the two most variable traits we studied but dimorphism was
 evolutionary labile in other traits. The keys for disentangling
 alternative explanations for dimorphism evolution are studies of natural
 and sexual selection, together with a deeper understanding of how
 microevolutionary parameters of evolvability relate to macroevolutionary
 patterns of divergence.
