Natural history collections (NHCs) are an important source of the long-term data needed to understand how biota respond ongoing anthropogenic climate change.These include taxon occurrence for ecological modeling, as well information that can be used reconstruct mechanisms through which changing climates.The full potential NHCs change research cannot fully realized until high-quality sets conveniently accessible research, but this requires higher priority placed on digitizing holdings most...
Identifying the environmental conditions that drive biogeographic structure remains a major challenge of biogeography, evolutionary ecology and increasingly, conservation biology. Here, we use multivariate classification trees to assess northeast Pacific (∼ 26–58°N) rocky intertidal species (406 algae invertebrates) from 102 field sites. Random forest analyses are used importance 29 variables, encompassing broad range potential drivers, predict structure. Analyses repeated for with different...
1. Body size is highly correlated with physiological traits, fitness, and trophic interactions. These traits are subject to change if there widespread reductions of body warming temperatures, which suggested as one the ‘universal’ ecological responses climate change. However, general patterns response temperature in insects have not yet emerged. 2. To address this knowledge gap, we paired wing length (as a proxy for size) 5331 museum specimens 14 species British Odonata historical data....
Aim We evaluate the stability of range limits rocky intertidal limpet, Lottia gigantea, over last c. 140 years, test validity abundant centre hypothesis, and indirectly roles played by recruitment limitation habitat availability in controlling limits. Because this species is size-selectively harvested, our results also allow us to assess conservation implications. Location The Pacific coast North America, from northern California southern Baja (41.74° N–23.37° N), encompassing entire L....
Animals with distinct life stages are often exposed to different temperatures during each stage. Thus, how temperature affects these should be considered for broadly understanding the ecological consequences of climate warming on such species. For example, variation particular may affect respective change in body size, phenology and geographic range, which have been identified as "universal" responses change. While has separately documented across a number species, it is not known whether...
Abstract Chironomids are a useful group for investigating body size responses to warming due their high local abundance and sensitivity environmental change. We collected specimens of six species chironomids every 2 weeks over 2-year period (2017–2018) from mesocosm experiments using five ponds at ambient temperature 4°C higher than temperature. investigated (1) wing length within between sexes regression analysis, (2) interspecific test whether the influences warming, (3) correlation...
Abstract Natural history collections are invaluable resources for understanding biotic response to global change. Museums around the world currently imaging specimens, capturing specimen data and making them freely available online. In parallel digitisation effort, there have been great advancements in computer vision: trained automated recognition/detection, measurement of features digital images. Applying vision digitised natural has potential greatly accelerate use these change research....
The importance of large breeding individuals for maintaining the health marine fish and invertebrate populations has long been recognized. Unfortunately, decades human harvesting that preferentially remove larger have led to drastic reductions in body sizes many these species. Such size-selective is particularly worrisome sequentially hermaphroditic species where size classes are composed primarily one sex. Whether can maintain stable sex ratios under sustained pressure depends on level...
Factors shaping the geographic range of a species can be identified when phylogeographic patterns are combined with data on contemporary and historical distribution, range-wide abundance, habitat/food availability, through comparisons codistributed taxa. Here, we evaluate dynamism phylogeography rocky intertidal gastropod Mexacanthina lugubris across its - Pacific coast Baja peninsula southern California. We sequenced mitochondrial DNA (CO1) from ten populations compliment these museum...
Abstract Aim To evaluate the existence of a latitudinal gradient richness ( LGR ) in rocky intertidal gastropods and role evolutionary processes shaping . Location The entire eastern P acific coast, from A laska to T ierra del F uego, encompassing ca. 120° latitude. Methods was assessed using field surveys comprehensive literature dataset 308 sites, representing 328 species 159 genera. importance geographic patterns diversification three complementary approaches. First, we used fossil record...
Body size has been shown to decrease with increasing temperature in many species, prompting the suggestion that it is a universal ecological response. However, species complex life cycles, such as holometabolous insects, may have correspondingly complicated temperature-size responses. Recent research suggests history and traits be important for determining direction strength of Yet, these factors are rarely included analyses. Here, we aim determine whether bivoltine butterfly, Polyommatus...
Phylogenetic analyses for molluscs frequently make use of the mitochondrial (mt) markers COX1, 12S and 16S, in part because availability universal primers (e.g. Plazzi & Passamonti, 2010; Williams et al., Aktipis Giribet, 2011; Wakabayashi 2012). Recent phylogenetic studies have expanded on gene sampling, sequenced entire mt genomes undertaken using all protein-coding rRNA genes determining relationships within Mollusca, generally resulting well-resolved trees with highly supported nodes...
Abstract Aim The relationship of population genetics with the ecology and biogeography species may be explored by comparing phenotypically similar but ecologically different congeners overlapping ranges. We compared genetic differentiation between two congeneric rocky intertidal gastropods across a major portion their sympatric range. hypothesized that habitat generalist high abundance continuous distribution would exhibit comparatively less than specialist low fragmented distribution....
Intertidal communities are more frequently experiencing extreme air and sea temperatures as a result of anthropogenic climate change, with heatwaves increasing in intensity duration. Most studies exploring the thermal tolerances intertidal species to haven't directly studied early life stages. We explored whether locally tide-out were lethally impacting premature Boreal (Littorina littorea Steromphala cineraria) Lustanian (Phorcus lineatus umbilicalis) gastropod from southwest England. Two...
Size-selective harvesting can elicit a genetic response in target species through changes population subdivision, diversity and selective regimes. While harvest-induced change has been documented some commercially important the use of historic samples, many commonly harvested species, such as coastal molluscs, lack samples information on potential harvest induced change. In this study, we have genotyped six microsatellite markers from populations across much California mainland range...
Abstract Aim The biogeography of predator‐induced defences is an understudied area predator–prey dynamics. Range overlap with predators that induce the response and local demographics (e.g., prey abundances) are likely to be important factors for determining biogeographic distribution induced within species. However, climate warming, range‐expanding warm‐water increasingly preying upon temperate This a consequence wider phenomenon known as tropicalisation. We aim determine: (i) if...
