title: Data from: Aquatic omnivores shift their trophic position towards increased plant consumption as plant stoichiometry becomes more similar to their body stoichiometry

description: Human induced eutrophication has strongly altered aquatic ecosystems. With
 increasing eutrophication, plant nutrient concentrations increase, making
 them more attractive as food for herbivores. However, most aquatic
 consumers are omnivorous. Ecological stoichiometry theory predicts that
 animals prefer to consume food which has a similar nutrient (N and P)
 composition or C:nutrient ratio compared to their own bodies, hence
 omnivorous animals may prefer to eat animal prey instead of plants. We ask
 whether aquatic omnivores would shift their diet towards more plant
 consumption when plants are more nutritious and their stoichiometry
 becomes more similar to the stoichiometry of the omnivore. We hypothesized
 that: (1) the omnivore increases plant consumption as the plant C:nutrient
 ratio decreases when there is only plant material available; (2) the
 omnivore generally prefers animal food over plant material; (3) the
 omnivore will increase its relative plant consumption as the plant
 C:nutrient ratio decreases, in the presence of animal food. As a model
 system, we used the pond snail Lymnaea stagnalis (omnivorous consumer),
 the aquatic plant Potamogeton lucens (plant food to the consumer, cultured
 at different nutrient regimes to obtain different plant C:nutrient
 ratios), and the crustacean Gammarus pulex (animal food to the consumer,
 using freshly dead individuals). When there was only plant material
 available, the consumers increased their relative consumption rate with
 decreasing plant C:nutrient ratio from no measurable amount to about 102
 mg g-1 day-1. When plant material was offered simultaneously with animal
 food, even though the omnivores always preferred animal food over plant
 material, the omnivores still increased their relative intake of plant
 material as plant C:nutrient ratio decreased, from virtually nothing at
 the highest to on average 16% of their diet at the lowest plant C:nutrient
 ratio, with a maximum of 28%. Therefore, we conclude that as nutrient
 loading increases in aquatic ecosystems, plant-eating omnivorous animals
 may shift their trophic position towards increased plant consumption and
 alter the food web structure. As a result, we may observe increased
 top-down control on aquatic plants.

title: Data from: Shifts in plant nutrient content in combined warming and drought scenarios may alter reproductive fitness across trophic levels

description: Ecological effects of climate change are difficult to predict because
 climate change is a multi‐variable phenomenon that can impact ecosystems
 through diverse pathways. Despite this fact, climate change ecology
 research has been dominated by relatively simplistic experiments and
 models. To test the importance of assessing more realistic climate and
 ecological scenarios an experiment was conducted to assess the interactive
 effects of multiple climate change variables (warming, drought) on
 survival and reproductive fitness across three trophic levels within a
 well‐studied terrestrial food web. The effects of warming and drought on
 the nutrient content of plants and how such changes may affect consumers
 was also examined. Results showed that warming and drought in combination
 can significantly alter the nutrient profiles of plants relative to
 climate variables in isolation and that multi‐variable climate change can
 severely impact plant reproductive fitness. Also, consumer nutrient
 profiles did not shift in accordance with their resources, but
 reproductive fitness of grasshoppers was nonetheless severely affected by
 warming and drought in combination. Predator survival rates decreased by
 more than 50% under all climate change scenarios, highlighting the
 variable responses of different trophic levels. The impacts across the
 entire food web were likely caused by a combination of metabolic changes
 due to warming, dehydration, altered nutrient availability and resource
 quality, and behavioral shifts. The results suggest that realistic climate
 change scenarios could dramatically affect long‐term demographic patterns
 as well as food web dynamics, and that single variable studies may fail to
 reveal the true impacts of climate change.

title: Data from: Investigating the timing of origin and evolutionary processes shaping regional species diversity: insights from simulated data and Neotropical butterfly diversification rates

description: Different diversification scenarios have been proposed to explain the
 origin of extant biodiversity. However, most existing meta-analyses of
 time-calibrated phylogenies rely on approaches that do not quantitatively
 test alternative diversification processes. Here, I highlight the
 shortcomings of using species divergence ranks, which is a method widely
 used in meta-analyses. Divergence ranks consist of categorizing
 cladogenetic events to certain periods of time, typically to either
 Pleistocene or to pre-Pleistocene ages. This approach has been claimed to
 shed light on the origin of most extant species and the timing and
 dynamics of diversification in any biogeographical region. However,
 interpretations drawn from such method often confound two fundamental
 questions in macroevolutionary studies, tempo (timing of evolutionary rate
 shifts) and mode (“how” and “why” of speciation). By using simulated
 phylogenies under four diversification scenarios, constant-rate,
 diversity-dependence, high extinction, and high speciation rates in the
 Pleistocene, I showed that interpretations based on species divergence
 ranks might have been seriously misleading. Future meta-analyses of dated
 phylogenies need to be aware of the impacts of incomplete taxonomic
 sampling, tree topology, and divergence time uncertainties, as well as
 they might be benefited by including quantitative tests of alternative
 diversification models that acknowledge extinction and diversity
 dependence.

title: Data from: The ability of North Island robins to discriminate between humans is related to their behavioural type

description: Animals are able to learn to identify persistent threats to themselves and
 their offspring. For example, birds are able to quickly learn to
 discriminate between humans that have previously threatened their nests
 from humans with whom they have had no prior experience. However, no study
 has yet examined whether a bird's ability to discriminate between
 humans is related to the bird's underlying behavioural type. In this
 study, we examined whether there were differences among North Island (NI)
 robins (Petroica longipes), based on their underlying behavioural type, in
 their abilities to discriminate between familiar and novel human
 observers. Using a simple feeding experiment, we timed how long it took
 birds to attack a food item placed next to an observer on each of 7 days.
 On the eighth day, a different observer timed the birds. We found that
 birds could be split into two behaviour types based on their attack
 behaviour: fast attackers (latencies &lt;20 sec) and slow attackers
 (latencies &gt;20 secs). Interestingly, the fast birds did not
 increase their attack latency in response to the novel observer whereas
 the slow attackers did. This result, for the first time, demonstrates that
 a bird's ability to discriminate between humans can vary among birds
 based on their behavioural type.

title: Data from: Integration between swimming and feeding evolves repeatedly in Trinidadian guppies and aligns with suction-feeding fishes

description: Well-supported correlations between swim speed and mouth size during prey
 capture suggest broad existence of an integrated relationship between
 locomotion and feeding in suction-feeding fishes. However, the influence
 of specialization on this relationship is unclear. We use divergent
 populations of Trinidadian guppies (Poecilia reticulata) to test whether
 integration during suction is generalizable to a non-suction specialist
 and whether intraspecific specialization of component systems affects
 their integration. Guppies from replicate high and low predation streams
 were recorded capturing wild-type zooplankton using suction. Alternative
 general linear models supported a positive correlation between swim speed
 and mouth size in derived low predation populations suggesting that the
 relationship can be extended in some cases. High predation populations
 lack this integration which may be the result of direct selection or
 constraints imposed by selection on locomotion. As guppies invade new
 habitats they may be evolving a new, integrated performance phenotype from
 a non-integrated ancestor.

title: Data from: Where do wintering cormorants come from? Long-term changes in the geographical origin of a migratory bird on a continental scale

description: 1. Populations of migratory birds often mix to a considerable extent in
 their wintering areas. Knowledge about the composition of wintering
 populations is highly relevant in relation to management, not least for
 species, such as the great cormorant Phalacrocorax carbo sinensis, prone
 to conflicts with human interests. However, few studies have been able to
 estimate long-term changes in winter population composition. 2. We use 30
 years of ringing and recovery data (1983-2013) from all major breeding
 populations of cormorants in continental Europe (except the Black Sea
 region) to estimate partitioning probabilities (i.e. the probabilities of
 moving to specific wintering areas) using a Bayesian capture-mark-recovery
 model. Combining these results with information on breeding numbers and
 reproductive output in a population model, we estimate the size and
 composition of wintering populations in Europe and North Africa. 3.
 Partitioning probabilities showed some variation over time, but were
 similar for first-winter and older birds. Cormorants from the western part
 of the breeding range tended to winter progressively further west over
 time. This may be a density-dependent response to the recent growth of
 more easterly breeding populations. 4. All wintering populations grew
 rapidly over the study period, and their composition showed pronounced
 changes. All wintering populations were composed of birds from many
 different breeding populations, but the proportion of cormorants of more
 easterly origin increased markedly over time in most wintering areas. 5.
 Policy implications. Cormorant wintering populations in Europe consist of
 mixtures of birds of different breeding origin, and these mixtures are
 highly variable over time. This reduces the chances of successfully
 limiting conflicts in a specific wintering area through e.g. regulation of
 breeding numbers in one breeding area. The dynamic nature of cormorant
 winter populations means that conflicts are best addressed when and where
 the conflict occurs, or on the scale of the entire continental population.
 It is unlikely that the latter will be cost-effective and politically
 realistic.09-Jan-2018

title: Data from: Dead ant walking: a myrmecophilous beetle predator uses parasitoid host location cues to selectively prey on parasitized ants

description: Myrmecophiles (i.e. organisms that associate with ants) use a variety of
 ecological niches and employ different strategies to survive encounters
 with ants. Because ants are typically excellent defenders, myrmecophiles
 may choose moments of weakness to take advantage of their ant associates.
 This hypothesis was studied in the rove beetle, Myrmedonota xipe, which
 associates with Azteca sericeasur ants in the presence of parasitoid
 flies. A combination of laboratory and field experiments show that M. xipe
 beetles selectively locate and prey upon parasitized ants. These
 parasitized ants are less aggressive towards beetles than healthy ants,
 allowing beetles to eat the parasitized ants alive without interruption.
 Moreover, behavioural assays and chemical analysis reveal that M. xipe are
 attracted to the ant's alarm pheromone, the same secretion used by
 the phorid fly parasitoids in host location. This strategy allows beetles
 access to an abundant but otherwise inaccessible resource, as A.
 sericeasur ants are typically highly aggressive. These results are the
 first, to our knowledge, to demonstrate a predator sharing cues with a
 parasitoid to gain access to an otherwise unavailable prey item.
 Furthermore, this work highlights the importance of studying
 ant–myrmecophile interactions beyond just their pairwise context.

title: Data from: Evaluating tools for the spatial management of fisheries

description: 1. The ability to define the spatial dynamics of fish stocks is critical
 to fisheries management. Combating illegal, unreported and unregulated
 (IUU) fishing and the implementation of area based management through
 physical patrols and port side controls are growing areas of management
 attention. Augmenting the existing approaches to fisheries management with
 forensic techniques has the potential to increase compliance and
 enforcement success rates. 2. We tested the accuracy of three techniques
 that can be used to identify geographic origin (genotyping, otolith
 microchemistry and morphometrics). We used fish caught from three fishing
 grounds separated by a minimum of 5km and a maximum of 60km to list the
 accuracy of these approaches at relatively small spatial scales. 3. Using
 nearest-neighbor analyses, morphometric analysis was the most accurate
 (79.5%) in assigning individual fish to their fishing ground of origin.
 Neither otolith microchemistry (54.0%) or genetic analyses (52.4%) had
 sufficient assignment accuracy at the spatial scales we examined. 4. The
 combination of accuracy and minimal resource requirements make
 morphometric analyses a promising tool for assessing compliance with area
 based fishing restrictions at the scale of kilometers and have promising
 application especially in small scale fisheries through to community-based
 management approaches where technical and financial resources are
 limited.22-Jun-2018

title: Data from: Within- and trans-generational effects of herbivores and detritivores on plant performance and reproduction

description: 1. Mutualistic and antagonistic aboveground and belowground species have
 the potential to be involved in strong interactions that can either weaken
 or strengthen their individual impacts on plants. Their impacts can also
 have delayed effects on a plant's progeny by altering offspring
 traits and survival. Few studies have explored the effect of herbivore and
 detritivore interactions with parent plants on offspring vital life-cycle
 processes, such as seedling emergence rate, seedling establishment, and
 offspring survival. 2. In the field, I experimentally studied the combined
 effects of floral herbivores, root herbivores, and detritivores on plant
 growth and reproduction of Moricandia moricandioides (Brassicaceae). In
 particular, I analysed the trans-generational effects of herbivores and
 detritivores on seed and juvenile production as well as on vital
 life-cycle processes (i.e. seedling emergence rates, survival). 3. Floral
 herbivores strongly reduced the number of flowers, fruits, seeds, and
 juveniles. Detritivores had an impact on plant success by increasing seed
 quality (% N and N:C ratio), although the effect was altered by the
 presence of floral and root herbivores. 4. I found maternal effects
 (trans-generational effects) of floral herbivores, root herbivores, and
 detritivores. Floral herbivores reduced seedling emergence and
 establishment. Floral and root herbivores in combination reduced seedling
 emergence timing, but the effect was counteracted by detritivores.
 Detritivores also reduced the negative effect of floral herbivores on
 offspring mortality rate. 5. This study shows that the impact of
 aboveground and belowground organisms on M. moricandioides plants go
 beyond seed production and were evident in the probability of
 establishment and survival of the following generation. Trans-generational
 effects were induced by all three groups of interacting organisms and the
 net consequences for plant offspring depended on the organisms interacting
 with the plant.

title: Data from: Climate niche differentiation between two passerines despite ongoing gene flow

description: Niche evolution underpins the generation and maintenance of biological
 diversity, but niche conservatism, in which niches remain little changed
 over time in closely related taxa and the role of ecology in niche
 evolution are continually debated. To test whether climate niches are
 conserved in two closely related passerines in East Asia – the
 vinous-throated (Paradoxornis webbianus) and ashy-throated (P.
 alphonsianus) parrotbills – we established their potential allopatric and
 sympatric regions using ecological niche models and compared differences
 in their climate niches using niche overlap indices in background tests
 and multivariate statistical analyses. We also used polymorphism data on
 44 nuclear genes to infer their divergence demography. We found that these
 two parrotbills occupy different climate niches, in both their allopatric
 and potential sympatric regions. Because the potential sympatric region is
 the area predicted to be suitable for both parrotbills based on the
 ecological niche models, it can serve as a natural common garden.
 Therefore, their observed niche differences in this potential sympatry
 were not simply rendered by phenotypic plasticity, and probably had a
 genetic basis. Our genetic analyses revealed that the two parrotbills are
 not evolutionarily independent for the most recent part of their
 divergence history. The two parrotbills diverged c. 856,000 years ago, and
 have had substantial gene flow since a presumed secondary contact c.
 290,000 years ago. This study provides an empirical case demonstrating
 that climate niches may not be homogenized in nascent species in spite of
 substantial, ongoing gene flow, which in turn suggests a role for ecology
 in promoting and maintaining diversification among incipient species.
