FIGURE 10. Sorting protocol after a sample has been collected and databased (location, date, method of collection). Many families required further specific manipulation or arrangement, depending on the needs of the systematist (e.g. arrangement of parts on a microscope slide; size of pin or specific position on a pin). HMDS (hexamethyldisilazane) is a liquid used to dry insects through immersion and subsequent evaporation (Heraty & Hawks, 1998).

Positive genetic covariance and limited thermal tolerance constrain tropical insect responses to global warming
<p>Tropical ectotherms are particularly vulnerable to global warming because their physiologies are assumed to be adapted to narrow temperature ranges. This study explores three mechanisms potentially constraining thermal adaptation to global warming in tropical insects: 1. tradeoffs in genotypic performance at different temperatures (the jack-of-all-trades hypothesis) 2. positive genetic covariance in performance, with some genotypes performing better than others at viable temperatures (the 'winner and 'loser genotypes hypothesis) or 3. limited genetic variation as the potential result of relaxed selection and the loss of genes associated with responses to extreme temperatures (the gene decay hypothesis). We estimated changes in growth and survival rates at multiple temperatures for three tropical rain forest insect herbivores (<i>Cephaloleia</i> rolled-leaf beetles, Chrysomelidae). We reared 2746 individuals in a full-sibling experimental design, at temperatures known to be experienced by this genus of beetles in nature (<i>i.e.</i>, 10-35°C). Significant genetic covariance was positive for 16 traits, supporting the 'winner and 'loser genotypes hypothesis. Only two traits displayed negative cross-temperature performance correlations. We detected a substantial contribution of genetic variance in traits associated with size and mass (0-44%), but low heritability in plastic traits such as development time (0-6%) or survival (0-4%). Lowland insect populations will most likely decline if current temperatures increase beyond 2°C. It is concerning that local adaption is already lagging behind current temperatures. The consequences of maintaining the current global warming trajectory would be devastating for tropical insects. However, if humans can limit or slow warming, many tropical ectotherms might persist in their current locations, and potentially adapt to warmer temperatures.</p>
