<p>This repository contains the coral growth data files used to generate the results for the following article:</p> <p> </p> <p>MJ. Vergotti, JP. D’Olivo, T. Brachert, P. Capdevila, J. Garrabou, C. Linares, P. Spreter, DK. Kersting (2024) Reconstruction of long-term sub-lethal effects of warming on a temperate coral in a climate change hot-spot. <em>Journal of Animal Ecology</em>. https://besjournals.onlinelibrary.wiley.com/doi/10.1111/1365-2656.14225</p> <p> </p> <p><strong>Abstract: </strong>The impact of warming on zooxanthellate corals is widespread, from tropical to temperate seas, with their associated mortalities causing global concern. The temperate coral <em>Cladocora caespitosa</em> is the only zooxanthellate coral with reef-building capacity in the Mediterranean Sea, a climate change hotspot with warming rates triple the global average. Over the past two decades, <em>C. caespitosa</em> populations have suffered severe mortality events associated with marine heatwaves (MHWs). However, with monitoring efforts beginning, at best, in the 2000s, the occurrence of MHWs before to that period, as well as the sub-lethal effects of these events remain poorly understood. Here we use sclerochronology to reconstruct the histories of past stress events and long-term sub-lethal effects on <em>C. caespitosa</em> in three locations within the NW Mediterranean Sea, each with different environmental conditions. Skeletal extension, density and calcification rates were compared to the <em>in situ</em> seawater temperature of each site to assess their relationship. Additionally, we assessed the occurrence of skeletal growth anomalies to reconstruct stress events between 1991 and 2021, a period that encompasses the onset and evolution of warming-related mass mortality events in the NW Mediterranean Sea. Our results reveal a positive association between calcification and temperature, following a latitudinal temperature gradient. However, the evolution of the likelihood distribution of growth rates in the warmest site (Columbretes Islands) since the 1990s indicates a decrease in linear extension and calcification rates during the most recent years. With the increase in the frequency of MHWs and growth anomalies during the last decade, this decline suggests a recurrence in physiological stress events. These results unravel information on the long-term impacts of warming on coral growth and highlight the potential of applying sclerochronology to reconstruct sub-lethal effects of warming using <em>C. caespitosa</em>. </p> <p> </p> <p> </p> <p><strong>Funding</strong>: This research is supported by the Horizon 2020 program of research and innovation of the European Union under the MaCoBioS grant agreement, by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation, project no. 401447620) and by the Spanish Ministry of Science, Innovation and Universities under the project UndResCoral (project no.

Data-set of studies on mortality, sub-lethal and reproductive effect on amphibians and reptiles
<p>Amphibians and reptiles have not been considered in environmental risk assessments of chemicals, which has generated some debate about whether risk posed by some pollutants like pesticides on these animals are covered by surrogates in the groups of fish, mammals and birds. In order to develop a scientifically sound and robust risk assessment scheme it is necessary to have enough information available on the biological relevance of effects observed in laboratory studies in view of population level effects, to identify sensitive life stages and to compare sensitivity of our target study groups with that of their surrogates.</p> <p>With these objectives, a systematic review of toxicological literature on amphibians and reptiles a comprehensive search of relevant literature on toxicity data related to amphibians and reptiles was conducted, using the appropriate search strings and combinations, in six different source types: multidisciplinary databases of scientific literature (i.e. Web of Science and Scopus), literature included in general amphibian and reptile ecotoxicology compilations, literature compiled in technical reports previously prepared for EFSA, literature sources used for creating amphibian or reptile records in the ecotoxicological database created by De Zwart (see references for details), literature sources used for creating amphibian or reptile records in toxicological online databases (United States Environmental Protection Agency’s Ecotoxicology Knowledgebase–ECOTOX, and National Library of Medicine’s Hazardous Substances Data Bank–HSDB), and indexes of herpetological scientific journals of local scope not included in Web of Science or Scopus.</p> <p>Data extraction consisted of the retrieval of relevant information, including among other fields: species, age, sex, chemical substance, exposure route and duration, type of recorded endpoint, type of response, exposure concentration, mean effect value of the control and exposed groups and the reported variability measures of these mean effects, and statistical significance of the comparison.</p> <ul> <li>Data category 1: Reporting endpoints. Endpoints are defined here as benchmark values obtained from the integration of responses measured at different concentrations (e.g. LC<sub>50</sub>, EC<sub>50</sub>, NOEC, for which calculation it is necessary to make a regression with the percentage of effect at different exposure concentrations).</li> <li>Data category 2: Reporting responses for each tested level. These are studies in which different replicates of experimental units are exposed to different levels (doses, concentrations), including a control treatment, and a magnitude of effect is recorded at each level. For some of these studies it was possible to calculate an endpoint (e.g. LC<sub>50</sub>, EC<sub>50</sub>, NOEC) and for others it was not (e.g. if only one concentration was tested or if a statistically significant adjustment between exposure level and effect cannot be achieved).</li> </ul> <p> </p> <p>Three objectives corresponding to the review of the effects of chemicals on amphibians and reptiles, the main results of the study were:</p> <ol> <li>Identification of the most sensitive life stage.</li> <li>Extrapolation from laboratory data to mesocosm and field situations</li> <li>Comparison with surrogate taxa</li> </ol> <p>The review was conducted on 3642 full-text records for chemical exposure effects and 556 for life history traits, out of which 1332 and 204, respectively, were finally used for data extraction. The datasets comprised 23152 values corresponding to effects of chemicals and 1854 values corresponding to life history traits.</p>
Co-formulant in a commercial fungicide product causes lethal and sub-lethal effects in bumble bees
<p>The dataset and code behind an experimental paper in Scientific Reports. </p> <p>Paper DOI: https://doi.org/10.1038/s41598-021-00919-x</p> <p>Pollinators, particularly wild bees, are suffering declines across the globe, and pesticides are thought to be drivers of these declines. Research into, and regulation of pesticides has focused on the active ingredients, and their impact on bee health. In contrast, the additional components in pesticide formulations have been overlooked as potential threats. By testing an acute oral dose of the fungicide product Amistar, and equivalent doses of each individual co-formulant, we were able to measure the toxicity of the formulation and identify the ingredient responsible. We found that a co-formulant, alcohol ethoxylates, caused a range of damage to bumble bee health. Exposure to alcohol ethoxylates caused 30% mortality and a range of sublethal effects. Alcohol ethoxylates treated bees consumed half as much sucrose as negative control bees over the course of the experiment and lost weight. Alcohol ethoxylates treated bees had significant melanisation of their midguts, evidence of gut damage. We suggest that this gut damage explains the reduction in appetite, weight loss and mortality, with bees dying from energy depletion. Our results demonstrate that sublethal impacts of pesticide formulations need to be considered during regulatory consideration, and that co-formulants can be more toxic than active ingredients.</p>
Consumption of pollen contaminated with field-realistic concentrations of fungicide cause sub-lethal effects in common eastern bumble bee (Bombus impatiens [Hymenoptera]: [Apidae]) microcolonies
<p>Bumble bees are declining across the globe. Causes of this decline have been attributed to a variety of stressors, including pesticides. Fungicides are a type of pesticide that have been understudied in the context of bumble bee health. As a result, fungicides are often applied to flowering plants without consideration of pollinator exposure. Recent work demonstrates that fungicides have sublethal effects in bumble bees, but little is known about how much fungicide it takes to cause these sublethal effects. To address this gap in the literature, we fed microcolonies of the common eastern bumble bee (<em>Bombus impatiens</em>) pollen contaminated with a range of fungicide concentrations. We chose these concentrations based on the range of fungicide concentrations in pollen and nectar that were reported in the literature. Results revealed that later-stage pupae and newly emerged males are potentially sensitive to fungicide exposure, showing smaller size and reduced fat reserves at intermediate levels of contamination. Compared to the control, intermediated levels of fungicide-contaminated pollen led to increased pupal mortality and delayed male emergence. Contrary to expectations, higher fungicide levels did not exhibit a linear relationship with negative impacts, suggesting nuanced effects. Because body size and emergence timing are important aspects of bumble bee reproductive behavior, results have implications for mating success, potentially disrupting colony development.</p>
