Pesticide exposure triggers sex-specific inter- and trans-generational effects conditioned by past sexual selection
<p>Environmental variation often induces plastic responses in organisms that can trigger changes in subsequent generations through non-genetic inheritance mechanisms. Such transgenerational plasticity thus consists of environmentally-induced non-random phenotypic modifications that are transmitted through generations. Transgenerational effects may vary according to the sex of the organism experiencing the environmental perturbation, the sex of their descendants, or both, but whether they are affected by past sexual selection is unknown. Here we use experimental evolution on an insect model system to conduct a first test of the involvement of sexual selection history in shaping transgenerational plasticity in the face of rapid environmental change (exposure to pesticides). We manipulated evolutionary history in terms of the intensity of sexual selection for over 80 generations before exposing individuals to the toxicant. We found that sexual selection history constrained adaptation under rapid environmental change. We also detected intergenerational and transgenerational effects of pesticide exposure in the form of increased fitness and longevity. These cross-generational influences of toxicants were sex-dependent (they affected only male descendants), and intergenerational, but not transgenerational, plasticity was modulated by sexual selection history. Our results highlight the complexity of intragenerational, intergenerational, and transgenerational influences of past selection and environmental stress on phenotypic expression.</p>
Adult germ free and specific pathogen free plethysmography recordings and metadata
<p>Included in this dataset are the original LabChart recordings used to study the effects of gut dysbiosis (germ-free vs. specific pathogen-free) on respiratory and metabolic outcomes in adult mice. Also included are settings files for running SASSI in Breathe Easy and the metadata file associated with these recordings. STAGG settings files are not included as they differ by figure, but they are available upon request to the corresponding author.</p>

Figure 5 in A simplistic water body-specific risk assessment model for zebra mussel (Dreissena polymorpha) establishment based on physicochemical characteristics
Figure 5. Overall zebra mussel establishment risk categorization of 133 Texas water bodies based on calcium, pH, salinity, and temperature. Major water bodies not included in this study due to lack of TCEQ water quality data are shown for context of the study extent. The Whittier et. al. low calcium/low risk zone delineation is shown to demonstrate level of agreement with that study, which is relatively high with some noteworthy exceptions. The Cypress, Sabine, and Neches River basins referenced in the text are the three East Texas basins with predominantly minimal risk water body categorizations.

Figure 3. Phylogenetic relationships and intra specific recombination patterns among different AlYVV molecules. The maximumlikelihood phylogenetic tree contains 27 known complete genomes of AlYVV from databank and two complete genomes determined in this study (indicated in black boxes). The tree was rooted on ToLCNDV (AB613826) as an out-group. The schematic representation of recombination events detected by RDP4. Arrows and blocks at the bottom correspond respectively to open reading frames (ORFs) and intergenic regions: pre-coat protein (AV2), coat protein (CP), replication-associated proteins (Rep and REn), transcriptional protein (TrAP), and AC4 region. AlYVV from different countries were colored differently. The colors of blocks represent the different ALYVV species and strains. Numbers at nodes indicate bootstrap confidence scores (1000 replicates).
