Local climate adaptation and gene flow in the native range of two co-occurring fruit moths with contrasting invasiveness
<p><span class="fontstyle01"><span>Invasive species pose increasing threats to global biodiversity and ecosystems. While previous studies have characterized successful invaders from ecological traits, characteristics related to evolutionary processes have rarely been investigated. Here we compared gene flow and local adaptation using demographic analyses and outlier tests in two co-occurring moth pests across their common native range of China, one of which (the peach fruit moth, </span></span><span class="fontstyle01"><span><i>Carposina</i></span></span> <span class="fontstyle01"><span><i>sasakii</i></span></span><span class="fontstyle01"><span>) has maintained its native distribution, while the other (the oriental fruit moth, </span></span><span class="fontstyle01"><span><i>Grapholita molesta</i></span></span><span class="fontstyle01"><span>)</span></span><span class="fontstyle01"><span> has expanded its range globally during the past century. We found that both species showed a pattern of genetic differentiation and an evolutionary history consistent with a common southwestern origin and northward expansion in their native range. However, for the noninvasive species, genetic differentiation was closely aligned with the environment, and there was a relatively low level of gene flow, whereas in the invasive species, genetic differentiation was associated with geography. Genome scans </span></span><span class="fontstyle01"><span>indicated stronger patterns of climate-associated loci</span></span><span class="fontstyle01"><span> in the noninvasive species.

Underwater light attenuation inhibits native submerged plants and facilitates the invasive co-occurring plant Cabomba caroliniana
<p><span>Decreasing in the diversity and distribution of native submerged plants have been widely observed in recent decades. Global underwater darkening, which is mainly caused by radiation dimming and a decrease in transparency due to e.g. eutrophication, </span><span>has emerged as a general trend that strongly hampers the growth of submerged plants in lakes by decreasing the light available for photosynthesis. However, few studies have attempted to compare the responses of native and invasive submerged plants to underwater darkening. In this study, we aimed to compare the effects of light attenuation on the growth and photosynthesis traits of native and invasive submerged plants.</span></p>
Data and code from: Thermal niche and habitat use by co-occurring lake trout (Salvelinus namaycush) and brook trout (S. fontinalis) in stratified lakes
<p>Realized thermal niche and habitat use are two conceptualizations of fish habitat based on organismal performance or lake-specific ecology, respectively. Both habitat types were compared for lake trout (<em>Salvelinus</em> <em>namaycush</em>) and brook trout (<em>S</em>. <em>fontinalis</em>) co-occurring in four large (> 500 ha) oligotrophic lakes. Lakes were partitioned into two morphological categories based on possession of a central or non-central deep basin with corresponding differences in adjoining shelf areas. Lake asymmetry in basin location has been shown to strongly influence food web connections based on isolation of basins from shelf areas.</p> <p>Generally, overlap between both habitat types occurred in several comparisons with lake trout, suggesting that thermal habitat is a reasonable proxy for habitat use boundaries though not a full replacement for insights gained from habitat use models.</p> <p>For brook trout, overlap was not as consistent, especially for lakes with non-central basins. In central basin lakes, there were closer proximity between the two species and overlap in both thermal niche and habitat use models. There was very limited overlap of either habitat type in lakes with non-central basins. Further, there were no shared areas of interspecific overlap between thermal niche and habitat use in non-central basins pointing to additional complexity governing habitat partitioning between lake trout and brook trout in these types of lakes. The shelf area effect on spatial structure of habitat, and likely food web connections, can occur in lakes regardless of basin centrality so long as shelf areas are large. In this lake set, lakes were sufficiently large to observe this phenomenon.</p>
Data from: The Competitive exclusion – tolerance rule explains habitat partitioning among co-occurring species of burying beetles
<p>Habitat partitioning among co-occurring, ecologically similar species is widespread in nature and thought to be an important mechanism for coexistence. The factors that cause habitat partitioning, however, are unknown for most species. We experimentally tested among three alternative hypotheses to explain habitat partitioning among two species of co-occurring burying beetle (<em>Nicrophorus</em>) that occupy forest (<em>N. orbicollis</em>) and wetland (<em>N. hebes</em>) habitats. Captive experiments revealed that the larger <em>N. orbicollis </em>(forest) was consistently dominant to <em>N. hebes </em>(wetland) in competitive interactions for carcasses that they require for reproduction. Transplant enclosure experiments in nature revealed that <em>N. hebes</em> had poor reproductive success whenever the dominant <em>N. orbicollis</em> was present. In the absence of <em>N. orbicollis</em>, <em>N. hebes</em> performed as well, or better, in forest versus its typical wetland habitat. In contrast, <em>N. orbicollis </em>performed poorly in wetlands regardless of the presence of <em>N. hebes</em>. These results support the Competitive exclusion – tolerance rule where the competitively dominant <em>N. orbicollis</em> excludes the subordinate <em>N. hebes</em> from otherwise suitable or preferable forest habitat, while the subordinate <em>N. hebes</em> is uniquely able to tolerate the challenges of breeding in wetlands. Transplant experiments further showed that carcass burial depth – an important trait thought to enhance the competitive ability of the dominant <em>N. orbicollis</em> – is costly in wetland habitats. When in the presence of <em>N. hebes, N. orbicollis</em> buried carcasses deeper; deeper burial is thought to provide a competitive advantage in forests, but further compromised the reproductive success of <em>N. orbicollis </em>in wetlands. Overall, results provide evidence that the Competitive exclusion – tolerance rule underlies habitat partitioning among ecologically similar species, and that the traits important for competitive dominance in relatively benign environments are costly in more challenging environments, consistent with a trade-off.</p>
