title: Data from: A key floral scent component (β-trans-bergamotene) drives pollinator preferences independently of pollen rewards in seep monkeyflower

description: 1) Floral odors play an important role in attracting insect pollinators.
 Because pollinators visit flowers to obtain pollen and nectar rewards,
 they should prefer floral odor profiles associated with the
 highest-rewarding flowers (honest signals). In previous work, bumble bees
 exhibited a preference for flowers from outbred over inbred Mimulus
 guttatus plants. Pollen is the only floral reward in M. guttatus, and
 pollen viability (a reliable indicator of protein content) is reduced in
 inbred plants. Yet, differences in pollen viability did not explain the
 observed preferences. 2) In this study we examined the floral volatile
 profiles of inbred and outbred M. guttatus to identify inbreeding effects
 and associations between volatile compounds and the number of viable
 pollen grains per flower, designated ‘PRQ’ (pollen reward quality). We
 also conducted pairwise choice tests with Bombus impatiens to evaluate the
 ability of bees to discriminate between odors of rewarding and
 nonrewarding flowers and to determine whether bumble bee preferences are
 explained by differences in the floral odors of inbred and outbred plants.
 3) Inbred plants exhibited reduced emission of β-trans-bergamotene, the
 second-most abundant compound in the volatile blend of outbred plants.
 Furthermore, pollen and fertile anthers emitted nonadecane. Six other
 compounds in the floral blend were positively correlated with PRQ. There
 was no overlap between compounds affected by inbreeding and compounds
 associated with PRQ. 4) Even when given prior experience foraging on M.
 guttatus, bumble bees did not distinguish between the floral odors of
 rewarding and non-rewarding outbred plants. However, they preferred floral
 odors from non-rewarding outbred plants over rewarding inbred plants.
 Bumble bees without prior experience of flowers preferred volatile blends
 with higher versus lower amounts of β-trans-bergamotene. 5) Taken
 together, these results suggest that the volatile emissions of M. guttatus
 provide reliable indicators of pollen rewards (potential honest signals),
 but that the preference of bumble bees for outbred plants is not driven by
 these cues but rather by a sensory bias for β-trans-bergamotene. This may
 represent a subtle form of deceit-pollination that allows plants to
 attract pollinators while minimizing investment in costly rewards.

title: Data from: Large-brained birds suffer less oxidative damage

description: Large brains (relative to body size) might confer fitness benefits to
 animals. Although the putative costs of well-developed brains can
 constrain the majority of species to modest brain sizes, these costs are
 still poorly understood. Given that the neural tissue is energetically
 expensive and demands antioxidants, one potential cost of developing and
 maintaining large brains is increased oxidative stress (‘oxidation
 exposure’ hypothesis). Alternatively, because large-brained species
 exhibit slow-paced life histories, they are expected to invest more into
 self-maintenance such as an efficacious antioxidative defence machinery
 (‘oxidation avoidance’ hypothesis). We predict decreased antioxidant
 levels and/or increased oxidative damage in large-brained species in case
 of oxidation exposure, and the contrary in case of oxidation avoidance. We
 address these contrasting hypotheses for the first time by means of a
 phylogenetic comparative approach based on an unprecedented dataset of 4
 redox state markers from 85 European bird species. Large-brained birds
 suffered less oxidative damage to lipids (measured as malondialdehyde
 levels) and exhibited higher total non-enzymatic antioxidant capacity than
 small-brained birds, while uric acid and glutathione levels were
 independent of brain size. These results were not altered by potentially
 confounding variables and did not depend on how relative brain size was
 quantified. Our findings partially support the ‘oxidation avoidance’
 hypothesis and provide a physiological explanation for the linkage of
 large brains with slow-paced life histories: reduced oxidative stress of
 large-brained birds can secure brain functionality and healthy lifespan,
 which are integral to their lifetime fitness and slow-paced life history.

title: Data from: Antagonistic pleiotropy in species with separate sexes, and the maintenance of genetic variation in life-history traits and fitness

description: Antagonistic pleiotropy (AP) – where alleles of a gene increase some
 components of fitness at a cost to others – can generate balancing
 selection, and contribute to the maintenance of genetic variation in
 fitness traits, such as survival, fecundity, fertility, and mate
 competition. Previous theory suggests that AP is unlikely to maintain
 variation unless antagonistic selection is strong, or AP alleles exhibit
 pronounced differences in genetic dominance between the affected traits.
 We show that conditions for balancing selection under AP expand under the
 likely scenario that the strength of selection on each fitness component
 differs between the sexes. Our model also predicts that the vast majority
 of balanced polymorphisms have sexually antagonistic effects on total
 fitness, despite the absence of sexual antagonism for individual fitness
 components. We conclude that AP polymorphisms are less difficult to
 maintain than predicted by prior theory, even under our conservative
 assumption that selection on components of fitness is universally sexually
 concordant. We discuss implications for the maintenance of genetic
 variation, and for inferences of sexual antagonism that are based on
 sex-specific phenotypic selection estimates – many of which are based on
 single fitness components.

title: Data from: Revisiting the link between breeding effort and oxidative balance through field evaluation of two sympatric sibling insect species

description: The idea that oxidative stress could be a major force governing
 evolutionary trade-offs has recently been challenged by experimental
 approaches in laboratory conditions triggering extensive debates centered
 on theoretical and methodological issues. Here, we revisited the link
 between oxidative stress and reproduction by measuring multiple
 antioxidant and oxidative damages in wild-caught females of two sibling
 weevil species (Curculio elephas, C. glandium). The strength of our study
 arises from: (1) studied species are sympatric and exploit similar
 resource but display contrasting reproductive strategies and (2)
 individuals were sampled throughout adult life so as to relate oxidative
 status to breeding effort. We found that the short-lived C. elephas
 sacrifices red-ox homeostasis for immediate reproduction upon emergence as
 characterized by low antioxidant defenses and elevated oxidative damage.
 Comparatively, C. glandium massively invests in antioxidant and maintains
 low oxidative damage, which may contribute to their extended
 pre-reproductive period. Intriguingly, we also reveal, for the first time
 in a field study, an unexpected reactivation of antioxidant defenses with
 the onset of reproduction. Our results thus support the existence of a
 strong but complex relationship between oxidative stress and life history
 evolution and highlight the need for a finer-scale picture of antioxidant
 strategies.

title: Data from: Competition and constraint drove Cope's rule in the evolution of giant flying reptiles

description: The pterosaurs, Mesozoic flying reptiles, attained wingspans of more than
 10 m that greatly exceed the largest birds and challenge our understanding
 of size limits in flying animals. Pterosaurs have been used to illustrate
 Cope’s rule, the influential generalization that evolutionary lineages
 trend to increasingly large body sizes. However, unambiguous examples of
 Cope’s rule operating on extended timescales in large clades remain
 elusive, and the phylogenetic pattern and possible drivers of pterosaur
 gigantism are uncertain. Here we show 70 million years of highly
 constrained early evolution, followed by almost 80 million years of
 sustained, multi-lineage body size increases in pterosaurs. These results
 are supported by maximum-likelihood modelling of a comprehensive new
 pterosaur data set. The transition between these macroevolutionary regimes
 is coincident with the Early Cretaceous adaptive radiation of birds,
 supporting controversial hypotheses of bird–pterosaur competition, and
 suggesting that evolutionary competition can act as a macroevolutionary
 driver on extended geological timescales.

title: Data from: Silicon-induced root nodulation and synthesis of essential amino acids in a legume is associated with higher herbivore abundance

description: Ecologists have become increasingly aware that silicon uptake by plants,
 especially the Poaceae, can have beneficial effects on both plant growth
 and herbivore defence. The effects of silicon on other plant functional
 groups, such as nitrogen-fixing legumes, have been less well studied.
 Silicon could, however, indirectly promote herbivore performance in this
 group if reported increases in N2-fixation caused improvements in host
 plant quality for herbivores. We tested how silicon supplementation in the
 legume Medico sativa affected plant growth rates, root nodulation and
 foliage quality (silicon content and amino acid profiles) for an insect
 herbivore (Acyrthosiphon pisum). Plants supplemented with silicon (Si+)
 grew three times as quickly as those without supplementation (Si-), almost
 entirely in shoot mass. While root growth was unaffected by silicon
 uptake, root nodules containing nitrogen-fixing bacteria were 44% more
 abundant on Si+ plants. Aphid abundance was twice as high on Si+ plants
 compared to Si- plants and was positively correlated with
 silicon-stimulated plant growth. Si+ plants accumulated more than twice as
 much silicon as Si- plants, but did not have higher silicon concentrations
 because of dilution effects linked to the rapid growth of Si+ plants. Si+
 plants showed a 65% increase in synthesis of essential foliar amino acids,
 probably due to increased levels of root nodulation. These results suggest
 that increased silicon supply makes M. sativa more susceptible to A.
 pisum, mainly because of increased plant growth and resource availability
 (i.e. essential amino acids). While silicon augmentation of the Poaceae
 frequently improves herbivore defence, the current study illustrates that
 this cannot be assumed for other plant families where the beneficial
 effects of silicon on plant growth and nutrition may promote herbivore
 performance in some instances.

title: Data from: Using local ecological knowledge to monitor threatened Mekong megafauna in Lao PDR

description: Pressures on freshwater biodiversity in Southeast Asia are accelerating
 yet the status and conservation needs of many of the region’s threatened
 fish species are unclear. This impacts the ability to implement
 conservation activities and to understand the effects of infrastructure
 developments and other hydrological changes. We used Local Ecological
 Knowledge from fishing communities on the Mekong River in the Siphandone
 waterscape, Lao PDR to estimate mean and mode last capture dates of eight
 rare or culturally significant fish species in order to provide
 conservation monitoring baselines. One hundred and twenty fishermen, from
 six villages, were interviewed. All eight species had been captured, by at
 least one of the interviewees, within the waterscape within the past year.
 However the mean and mode last capture dates varied between the species.
 Larger species, and those with higher Red List threat status, were caught
 less recently than smaller species of less conservation concern. The
 status of the Critically Endangered Pangasius sanitwongsei (mean last
 capture date 116.4 months) is particularly worrying suggesting severe
 population decline although cultural issues may have caused this species
 to have been under-reported. This highlights that studies making use of
 Local Ecological Knowledge need to understand the cultural background and
 context from which data is collected. Nevertheless we recommend our
 approach, of stratified random interviews to establish mean last capture
 dates, may be an effective methodology for monitoring freshwater fish
 species of conservation concern within artisanal fisheries. If fishing
 effort remains relatively constant, or if changes in fishing effort are
 accounted for, differences over time in mean last capture dates are likely
 to represent changes in the status of species. We plan to repeat our
 interview surveys within the waterscape as part of a long-term
 fish-monitoring program.

title: Data from: A combined mesowear analysis of Mexican Bison antiquus shows a generalist diet with geographical variation

description: Bison antiquus was one of the largest and most widely distributed
 megafaunal species during the Late Pleistocene in North America, giving
 rise to the modern plains bison in the middle Holocene. Despite the
 importance of the ancient bison, little is known about its feeding
 ecology. We employed a combination of extended mesowear, and mesowear III
 to infer the diet preference and habitat use of three Mexican samples of
 B. antiquus. Two northern samples from the Transmexican Volcanic Belt
 morphotectonic Province: La Piedad-Santa Ana and La Cinta-Portalitos, as
 well as one southern sample from the Sierra Madre del Sur morphotectonic
 province: Viko Vijin. We found that the northern Mexican samples were
 primarily non-strict grazers, while the southern sample displays a pattern
 consistent with mixer feeder habits. This suggests variability among the
 diets of these bison samples, caused by different paleoenvironments. This
 evidence complements the paleoenvironmental reconstructions in the studied
 localities; for the northern samples, open prairies composed of patches of
 woodland or shrubland and for the southern locality a fluvial floodplain
 with short-lived vegetation. In both scenarios, grasses (Poaceae) were
 non-dominant. The dietary habits of our samples of ancient bison in Mexico
 are the southernmost dietary inference for the species in North America
 and expand our knowledge of the dietary habits of Bison antiquus during
 the late Pleistocene.

title: Data from: Effects of neonicotinoid insecticide exposure and monofloral diet on nest-founding bumblebee queens

description: Bumblebees are among the world’s most important groups of pollinating
 insects in natural and agricultural ecosystems. Each spring, queen
 bumblebees emerge from overwintering and initiate new nests, which
 ultimately give rise to workers and new reproductives later in the season.
 Nest initiation and survival are thus key drivers of both bumblebee
 pollination services and population dynamics. We performed the first
 laboratory experiment with the model bumblebee species Bombus impatiens
 that explores how early nesting success is impacted by the effects of
 temporary or more sustained exposure to sublethal levels of a
 neonicotinoid-type insecticide (imidacloprid at 5 ppb in nectar) and by
 reliance on a monofloral pollen diet, two factors that have been
 previously implicated in bumblebee decline. We found that queens exhibited
 increased mortality and dramatically reduced activity levels when exposed
 to imidacloprid, as well as delayed nest initiation and lower brood
 numbers in the nest, but partially recovered from these effects when they
 only received early, temporary exposure. The effects of pollen diet on
 individual queen- and colony-level responses were overshadowed by effects
 of the insecticide, although a monofloral pollen diet alone was sufficient
 to negatively impact brood production. These findings speak to the
 sensitivity of queen bumblebees during the nest initiation phase of the
 colony cycle, with implications for how queens and their young nests are
 uniquely impacted by exposure to threats such as pesticide exposure and
 foraging habitat unsuitability.

title: Data from: The first Cenozoic spinicaudatans from North America

description: A new spinicaudatan species, Estherites? jocelynae new species, is
 described from more than fiftyspecimens collected from the Medicine Lodge
 Formation (early Oligocene) of the Beaverhead Basin in southwestern
 Montana, USA. This is the first spinicaudatan species reported from
 Cenozoic strata of North America and is the second-youngest fossil clam
 shrimp described globally. The new species extends the range of the
 superfamily Estheriteoidea into the Paleogene. Carapaces of E.? jocelynae
 n. sp. are preserved as a calcium carbonate replacement of the original
 chitin-calcium-phosphate structure, which is an uncommon style of
 preservation for spinicaudatans. The unique preservation coupled with the
 range extension suggests that the sparse Cenozoic fossil record of
 spinicaudatans may be partly attributable to preservation bias related to
 geochemical conditions rather than exclusively to diversity decline
 following the end-Cretaceous mass extinction. The presence of E.?
 jocelynae n. sp. in the Medicine Lodge Formation indicates that lakes in
 the Beaverhead Basin experienced seasonality and fluctuating lake levels
 with at least some drying at the lake margins. The ecological inferences
 support previous paleoenvironmental interpretations based on
 paleobotanical and other faunal evidence.
