title: Habitat complexity and complex signal function – exploring the role of ornamentation

description: Animals often communicate in complex, heterogeneous environments, leading
 to hypothesized selection for increased detectability or discriminability
 in signaling traits. The extent to which secondary sexual ornaments have
 evolved to overcome the challenges of signaling in complex environments,
 however, remains understudied, especially in comparison to their role as
 indicator traits. This study tested the hypothesis that the
 condition-dependent secondary sexual ornamentation in the wolf spider
 Rabidosa rabida functions to increase detectability/discriminability in
 visually complex environments. We predicted that male ornamentation would
 interact with the complexity of the signaling environment to affect male
 mating success. In particular, we expected ornaments to confer a greater
 mating advantage when males courted in visually complex environments. To
 test this, we artificially manipulated male foreleg ornamentation
 (present/absent) and ran repeated-measures mating trials across laboratory
 microcosms that represented simple versus complex visual signaling
 environments. Microcosm visual complexity differed in their background
 pattern, grass stem color and grass stem placement. We found that
 ornamented males mated more often and more quickly than unornamented males
 across both environments, but we found no support for an
 ornament-by-environment interaction. Male courtship rate, however, did
 interact with the signaling environment. Despite achieving the same level
 of mating success across signaling environments, ornamented males courted
 less rapidly in complex versus simple environments, while environmental
 complexity had no influence on unornamented male courtship rates. Our
 results suggest that the visual complexity of the signaling environment
 influences the interactive influence of ornamentation and dynamic visual
 courtship on female mate choice.
description: This dataset was collected by live-scoring mating trials between
 male and female Rabidosa rabida wolf spiders. Males were assigned to one
 of two ornamentation treatments (ornamented/unornamented), corresponding
 to the color their forelegs were painted (black or brown, respectively).
 Each male then completed two mating trials, one in a simple microcosm and
 one in a complex microcosm, in random order. The dataset has been
 processed such that it includes only males that completed the entirity of
 the experiment (i.e., were assayed in both simple and complex
 microcosm types).

title: High capacity for a dietary specialist consumer population to cope with increasing cyanobacterial blooms

description: We present a common-garden experiment to study the feeding plasticity of a
 key deposit-feeder in the Baltic Sea, a low diversity system presenting a
 good model for studying local adaptations. Based on the latitudinal
 gradient in phytoplankton blooms, with a single diatom bloom (high
 nutritional quality) in the north and a diatom bloom followed by
 cyanobacteria bloom (low nutritional quality) in the south, we expected
 populations of the amphipod Monoporeia affinis to be dietary specialists
 in the north and generalists in the south.  We tested this
 hypothesis using a combination of stable isotope tracers, trophic niche
 analyses, and various endpoints of growth and health status. We found that
 the toxin-producing cyanobacteria, when mixed with diatoms, were
 efficiently incorporated and used for growth by both populations. However,
 contrary to the expectations, the feeding plasticity was more pronounced
 in the northern population, indicating genetically-based divergence and
 suggesting that this population is capable of ecological adaptation to the
 climate-induced northward cyanobacteria expansion in this system. Results
 provide important understandings for adaptations to increasing
 cyanobacteria in a future warming world in both limnic and marine
 ecosystems by invertebrates, but  are likely widely applicable to
 other consumers where questions on adaptations to altered food quality.

title: Plant defence syndromes on islands

description: Aim: It has been hypothesised that insular plant taxa have evolved reduced
 defences in response to lower herbivore pressure on islands. However, the
 few studies testing this hypothesis have addressed variation in individual
 defensive traits, without paying attention to patterns of correlated trait
 expression (i.e. defence syndromes). Location: Balearic and Canary
 Islands. Taxon: Ninety-one woody plant species. Methods: We tested whether
 plant species with contrasting histories of insularity (namely: endemics,
 non-endemic natives, and exotics) differed in their patterns of variation
 for a suite of morphological and chemical traits putatively associated
 with herbivory. For this, we measured eight leaf traits of 42 endemic, 29
 native non-endemic, and 20 introduced species for which specimens were
 sourced from botanical gardens found in two archipelagos: the Balearic and
 Canary Islands. Results: We conducted phylogenetic-controlled analyses
 which showed that, contrary to predictions, insular taxa (endemics and
 non-endemic natives) across both archipelagos similarly exhibited thicker,
 smaller, leaves with less nutrients and were physically more defended
 (especially the Balearic species) than exotic species. There were no
 differences in chemical defence (phenolic compounds) between endemics,
 non-endemic natives, and exotics. Finally, we also found what appeared to
 be differential syndromes between archipelagos: whereas species from the
 Balearic Islands were more physically defended, on average, those from the
 Canary Islands had higher chemical defences. Main conclusions: Overall,
 these results point to a functional-physical defence syndrome
 characteristic of insular plant taxa that is indistinct for endemic and
 non-endemic taxa, relative to introduced species, as well as quantitative
 and qualitative differences in defences between archipelagos owing to
 differences in species composition and likely also to different histories
 of biotic or abiotic pressure.

title: Negative body size-dependent resource allocation underlies conspicuous sexual ornaments in a territorial damselfly

description: Sexual ornaments, signaling individual quality to choosing females or
 rival males, often show steeper body size scaling compared to non-sexually
 selected traits. Theory posits such steeper body size scaling is the
 result of differential resource allocation, reflecting trade-offs between
 different components of fitness. Yet the process of resource allocation
 towards body size-dependent sexual ornaments has been rarely understood
 empirically. Using the Neotropical territorial
 damselfly Megaloprepus caerulatus, whose males and females carry
 wax-based, sex-specific white wing bands and white wing tips respectively,
 we investigated nutrition sensitivity and body size scaling of both traits
 by manipulating larval food availability and directly quantified both the
 fat allocated to wing ornaments and the fat reserve from which allocations
 are made. Both color traits exhibited sensitivity to food availability
 during larval development and steeper body size scaling compared to
 control traits. Although the absolute amount of fat invested in developing
 the color ornaments increased with body size, the proportion of total fat
 allocated to the ornaments decreased with body size, making exaggerated
 ornaments less affordable for smaller individuals. Our data demonstrate
 that knowledge of affordability of exaggeration for resource-based sexual
 ornament, which requires measuring the resource pool from which ornaments
 are derived is essential for understanding the maintenance of honesty of
 sexual signals.

title: Coastal squeeze on temperate reefs: long-term shifts in salinity, water quality, and oyster-associated communities

description: Foundation species such as mangroves, saltmarshes, kelps, seagrasses, and
 oysters thrive within suitable environmental envelopes as narrow ribbons
 along the land-sea margin. Therefore, these habitat-forming species and
 resident fauna are sensitive to modified environmental gradients. For
 oysters, many estuaries impacted by sea-level rise, channelization, and
 municipal infrastructure are experiencing saltwater intrusion and
 water-quality degradation that may alter reef distributions, functions,
 and services. To explore decadal-scale oyster-reef community patterns
 across a temperate estuary in response to environmental change, we
 resampled reefs in the Newport River Estuary (NRE) during 2013-2015 that
 were previously studied during 1955-1956. We also coalesced historical NRE
 reef distribution (1880s-2015), salinity (1913-2015), and water-quality
 driven shellfish closure boundary (1970s-2015) data to document
 environmental trends that could influence reef ecology and service
 delivery. Over the last 60-120 years, the entire NRE has shifted toward
 higher salinities. Consequently, oyster-reef communities have become less
 distinct across the estuary, manifest by 20-27% lower species turnover and
 decreased faunal richness among NRE reefs in the 2010s relative to the
 1950s. During the 2010s, NRE oyster-reef communities tended to cluster
 around a euhaline, intertidal-reef type more so than during the 1950s.
 This followed from faunal expansions farther up-estuary and biological
 degradation of subtidal reefs as NRE conditions became more marine and
 favorable for aggressive, reef-destroying taxa. In addition to these
 biological shifts, the area of suitable bottom on which subtidal-reefs
 persist (ultimately regulated by up-estuary intrusion of marine waters)
 and support human harvest (driven by water quality, eroding from
 up-estuary) has decreased by &gt;75% since the natural history of NRE
 reefs was first explored. This “coastal squeeze” on harvestable subtidal
 oysters (reduced from a 4.5-km to a 0.75-km envelope along the NRE’s main
 axis) will likely have consequences regarding the economic incentives for
 future oyster conservation, as well as the suite of services delivered by
 remaining shellfish reefs (e.g., biodiversity maintenance, seafood
 supply). More broadly, these findings exemplify how “squeeze” may be a
 pervasive concern for biogenic habitats along terrestrial or marine
 ecotones during an era of intense global change.

title: The impact of paleoclimatic changes on body size evolution in marine fishes

description: Body size is an important species trait, correlating with lifespan,
 fecundity, and other ecological factors. Over Earth’s geological history,
 climate shifts have occurred, potentially shaping body size evolution in
 many clades. General rules attempting to summarize body size evolution
 include Bergmann’s rule, which states that species grow to larger sizes in
 cooler environments and smaller sizes in warmer environments; and Cope’s
 rule, which poses that lineages tend to increase in size over evolutionary
 time. Tetraodontiform fishes (including pufferfishes, boxfishes, and ocean
 sunfishes) provide an extraordinary clade to test these rules in
 ectotherms owing to their exemplary fossil record and the great disparity
 in body size observed among extant and fossil species. We examined
 Bergmann’s and Cope’s rules in this group by combining phylogenomic data
 (1,103 exon loci from 185 extant species) with 210 anatomical characters
 coded from both fossil and extant species. We aggregated data layers on
 paleoclimate and body size from the species examined, then inferred a set
 of time-calibrated phylogenies using tip-dating approaches for use in
 downstream comparative analyses of body size evolution using models that
 incorporate paleoclimatic information. We find strong support for a
 temperature-driven model in which increasing body size over time is
 correlated with decreasing oceanic temperatures. On average, extant
 tetraodontiforms are 2–3 times larger than their fossil counterparts,
 which otherwise evolved during periods of warmer ocean temperatures. These
 results provide strong support for both Bergmann’s and Cope’s rules,
 trends that are less studied in marine fishes compared to terrestrial
 vertebrates and marine invertebrates.

title: Spore size data for free-sporing extant and fossil plants

description: The evolution of different spore size classes, or heterospory, is a
 fundamental reproductive innovation in land plants. The appearance of
 heterospory is particularly notable during the Devonian, when most known
 origins of the trait occur. Here we provide a perspective on the evolution
 of heterospory during this time interval, particularly from the late Early
 Devonian through the Middle Devonian (Emsian to Givetian stages; 408-383
 Ma), which shows an unusually high concentration of heterospory origins.
 We use theoretical considerations and compilations of fossil and extant
 spore sizes to suggest that the basic features of most heterosporous
 lineages, large spores and gametophytes that mature within the spore wall,
 are difficult to evolve in combination because large spores disperse
 poorly but small spores cannot support a functional gametophyte developing
 within their walls; evolving spores between 100-200 microns in diameter
 appears to represent a particularly important barrier for the evolution of
 heterospory. We then discuss why this barrier may have been lower in the
 Devonian, noting that the appearance and spread of heterospory is
 coincident with the emergence of peat accumulating wetland habitats. We
 suggest that more widespread wetland habitats would have generally lowered
 barriers to the evolution of heterospory by reducing dispersal limitation
 in larger spores. Ultimately, we suggest that the initial evolution of
 heterospory may be explained by major changes in sedimentology, thought to
 have been driven by plant evolution itself, that increased the diversity
 of terrestrial depositional environments and led to a greater number of
 habitats where large spores could be successful.

title: Swimming and schooling data of golden shiners in variable water temperatures

description: Temperature is highly influential on the physiology and behaviour of
 ectotherms. In fish, temperature affects social interactions such as
 schooling behaviour, a common defence against predation. However, the
 effect of temperature on the ability of schooling fish to collectively
 respond to a predator is unknown. Here we used a loom stimulus to simulate
 an approaching predator that elicited a fleeing response in schooling fish
 over a range of water temperatures (9-29°C) and group sizes (1-16 fish).
 While speed and acceleration always exhibited a positive curvilinear
 response to temperature, the optimal temperature at which performance
 peaked was different during the predation threat versus when they were
 unperturbed. Similarly, group-level metrics were sensitive to temperature
 immediately after a loom stimulus but showed no response to temperature
 during unperturbed swimming. The time taken for fish to respond to the
 loom stimulus was minimal at 20°C. The proportion of fish that startled,
 during a loom, peaked at 13°C – around the same temperature at which speed
 and acceleration were maximum. Taken together, our results suggest that
 ectothermic fish may be able to compensate for their slower swim speeds at
 lower temperatures during unperturbed swimming by increasing their
 sensitivity to startle in response to a predation threat. More generally,
 we show that in ectotherms the qualitative and quantitative effect of
 temperature on a behavioural trait may be dependent on the context.
description: Overhead video recordings of fish in shallow experimental water
 tanks were converted to pseudo-2D trajectories using idtracker.ai, which
 allows tracking of a large number of unmarked animals using deep neural
 networks to maintain identities and prevent error propagation after
 crossovers (Romero-Ferrero et al. 2019). Distance-related metrics, such as
 speed and acceleration, were scaled by the body length (BL) of the fish
 (Romero-Ferrero et al. 2019). Code from https://github.com/maria-kuruvilla/temp_collective_new was used to calculate the parameters in this dataset.

title: Data from: Ocean acidification alters sperm responses to egg-derived chemicals in a broadcast spawning mussel

description: The continued and unprecedented emissions of anthropogenic carbon dioxide
 (CO2) are causing progressive ocean acidification (OA). While deleterious
 effects of OA on biological systems are well documented in the growth of
 calcifying organisms, lesser studied impacts of OA include potential
 effects on gamete interactions that determine fertilisation, which are
 likely to influence the many marine species that spawn gametes externally.
 Here, we explore the effects of OA on the signalling mechanisms that
 enable sperm to track egg-derived chemicals (sperm chemotaxis). We focus
 on the mussel Mytilus galloprovincialis, where sperm chemotaxis enables
 eggs to selectively bias fertilisation in favour of genetically compatible
 males. Using a factorial experimental design, we test whether the
 experimental manipulation of seawater pH (comparing ambient conditions to
 predicted end-of-century scenarios) alters these patterns of differential
 sperm chemotaxis. While we find no evidence that patterns of male-female
 gametic compatibility are impacted by OA, we do find that individual males
 exhibit consistent variation in how their sperm perform in lowered pH
 levels. This finding of individual variability in the capacity of
 ejaculates to respond to chemoattractants under acidified conditions
 suggests that climate change will exert considerable pressure on male
 genotypes that can withstand an increasingly hostile fertilisation
 environment.
description: This dataset contains sperm counts and fertilisation rates
 following sperm chemotaxis trials in the mussel <em>Mytilus
 galloprovincialis</em>. Trials were performed in factorial blocks,
 each involving sperm from two focal males and egg chemoattractants from
 two focal females, crossed in all combinations and replicated twice. Each
 factorial block was performed separately and in entirety at two pH
 treatments, ambient (pH ~ 8.0) and low (pH ~ 7.6). Seawater carbonate
 chemistry data for the two treatments in each block are also
 provided.
