Ecomorphological relationships and invasion history of non-native terrestrial bird species on O'ahu, Hawai'i suggests ecological fitting during community assembly
The widespread introduction of species has created novel communities in many areas of the world. Since introduced species tend to have generalized ecologies and often lack shared evolutionary history with other species in their communities, it would be expected that the relationship between form and function (i.e. ecomorphology) may change in novel communities. We tested this expectation in a subset of the novel bird community on O'ahu, Hawai'i. By relating foraging behavior observations to morphology obtained from live birds at four sites across the island, we found many relationships between species' morphology and foraging ecology that mirrored relationships found in the literature for native dominated bird communities. Both movement and certain foraging behaviors were related to a species' tarsus to wing ratio. Further, bill morphology was related to gleaning, frugivory, and flycatching behaviors. The commonness of significant ecomorphological relationships suggests that, within O'ahu's novel bird community, form is strongly related to function. We hypothesize that ecological fitting likely played a major role in the assembly of this novel community conserving the relationships between form and function found in many other bird communities. To further support this hypothesis, we used niche data from EltonTraits 1.0 to determine if the establishment of bird species introduced to O'ahu was related to the distinctiveness of their ecological niche from the incumbent community. Introduced species were more likely to establish on O'ahu if their diets were less similar to the bird species already present on the island. Our results support the idea that ecological fitting is an important mechanism in shaping ecological communities, especially in the Anthropocene, thereby influencing novel community assembly and functioning.
An invasive species erodes the performance of coastal wetland protected areas
<p><span>The world has increasingly relied upon protected areas (PAs) to rescue highly valued ecosystems from human activities, but whether PAs will fare well with bioinvasions remains unknown. By analyzing three decades of seven largest coastal PAs in China, including multiple World Natural Heritage and/or Wetlands of International Importance sites, we show that although PAs are achieving success in rescuing iconic wetlands and critical shorebird habitats from once widespread reclamation, this success is counteracted by escalating plant invasions. Plant invasions were not only more extensive in PAs than non-PA controls, but also undermined PA performance by, without human intervention, irreversibly replacing expansive native wetlands (primarily mudflats), and precluding successional formation of new native marshes. Exotic species are invading PAs globally. This rare study across large spatiotemporal scales highlights that the consequences of bioinvasions for humanity's major conservation tool may be more profound, far-reaching and critical for management than currently recognized. </span></p>
