Summary: Hybridization is a significant factor contributing to the diversity of morphological and communicative signals in organisms. Through genetic, electron microscopy and spectrophotometry analysis of a distinct Heliodoxa hummingbird from Peru, it is found that this individual possesses genetic and nanostructural differences compared to other Heliodoxa hummingbirds. These findings suggest that hybridization plays a role in the structural color diversity observed in hummingbirds.

Summary: Understanding the causes and consequences of biological invasions is a challenge in ecology and conservation biology. Predicting which naturalized species become invasive is crucial for invasion management. This study examined the phylogenetic relatedness of invasive angiosperms compared to naturalized species in North America, finding that invasive species tend to be phylogenetically clustered and this clustering is more pronounced in regions with lower temperature and precipitation. This pattern may reflect the evolutionary conservatism of invasive traits and the greater invasiveness of species with novel trait combinations.

Summary: Biodiversity is under threat from global extinction, leading to a reduction in ecological trait diversity, evolutionary history, and ecosystem functioning and services. This study examines the impact of species losses on morphological and phylogenetic diversity in the global avian class and finds evidence of morphological homogenization but not phylogenetic homogenization. The loss of morphological diversity is expected to occur at a higher rate than predicted by species loss alone.

Summary: Shifts between native and alien climatic niches pose challenges for predicting biological invasions, especially for insular species. This study analyzed alien occurrences of endemic insular amphibians, reptiles, and birds and found that climatic mismatches were common in invasions of birds and reptiles, but less common in amphibians. Several predictors were identified for climatic mismatches, which varied among taxonomic groups.

Summary: This study explored the relationship between taxonomic diversity and evolutionary structure in vascular plant assemblages, finding positive correlations between ecological conservatism and native richness with average taxonomic distinctness, and a negative correlation with exotic species. However, the ambiguity and nonlinear relationship of richness suggest that it may not be a suitable bioindicator for wetlands. Further research is needed to understand how evolutionary structure plays a role in bioassessment.

Summary: The uneven distribution of biodiversity among different clades in nature shows that communication signals, such as plumage coloration in hummingbirds, play a crucial role in speciation. The study on 237 hummingbird species reveals that color evolution rates are associated with speciation rates, particularly in male plumage patches, suggesting an interplay between natural and sexual selection in driving speciation.

Summary: Hummingbirds show high dietary overlap in both invertebrate and plant resources, with few common families across individuals. Anna's Hummingbirds exhibit significantly higher invertebrate diet diversity compared to Black-chinned Hummingbirds in the same sites, but no differences were found in plant diet diversity among the 3 species. Urban hummingbirds have higher plant diet diversity than rural hummingbirds, with no effect of elevation on dietary richness.

Summary: Climate change has impacted the distribution and abundance of plant and animal species, including the threatened Orchidaceae family. The response of orchids to climate change remains largely unknown. A study on Habenaria and Calanthe species in China found that most Habenaria species will expand their ranges, while most Calanthe species will shrink their ranges dramatically. These findings emphasize the importance of considering climate-adaptive traits in orchid conservation.

Summary: This study evaluates trait relationships between frugivorous birds and palms at a global scale and identifies factors such as assemblage richness, climate, and biogeographic history that influence these relationships. The results show that trophic interactions have consistent influences on trait structure, but abiotic, biogeographic, and richness effects also play important roles in shaping the functional biogeography of mutualisms.

Summary: Globalization has accelerated the movement of species, particularly tropical birds, which are affected by climate change. As temperate regions become more tropical, the suitability for modelled invasive species increases with latitude. However, the tropics are becoming drier, limiting the potential for cross-continental invasion by tropical species. Forest loss around the tropics, where most traded birds reside, further compounds this trend. Conversely, the net gain in forest area in temperate regions may increase the potential for colonization by low-latitude birds. The combination of climate change, human transportation, and land-cover changes will likely accelerate the redistribution of species globally, leading to the emergence of non-analogue communities with unknown consequences.

Summary: By combining morphological, ecological, and life-history trait data with genomic-based estimates of changing effective population size, this study explores the demographic-based shifts in avian functional diversity over the past million years and under pre-anthropogenic climate warming. The results show that functional diversity remained relatively stable over this period, but significant changes occurred in some key areas of trait space due to changing species abundances. Furthermore, the study identifies the vulnerability of different regions of functional space among taxa, enhancing our understanding of losses of biosphere integrity before human disturbances and contemporary biodiversity loss.

Summary: To quantify the vulnerability of ecosystems to global change, it is important to understand how trophic ecosystem functions emerge. This study proposes the interaction functional space (IFS) as a conceptual framework to integrate the perspectives of functional diversity and network ecology. By applying this framework to seed dispersal and wood decomposition, the study demonstrates the influence of species interactions on the relationship between functional trait diversity and trophic functions. The IFS has potential future applications to elucidate mechanisms driving trophic functions and understand functional changes in ecosystems amidst global change.

Summary: Ecological niche modelling in terrestrial systems has been developed, but for marine species, using only latitude and longitude coordinates to extract environmental data may result in inaccurate training and prediction of species' geographical distributions. To address this issue, the voluModel R package was developed to efficiently extract three-dimensional environmental data for training ENMs and provide tools for visualization and estimation of model extrapolation risk. The use of three-dimensional environmental data improves the accuracy of training ENMs and inference of species' ecological niches and potential geographic ranges.

Summary: We investigated the impact of traits on speciation in hummingbirds, a clade with diverse speciation rates, morphology, and niches. Two hypotheses were tested, suggesting that speciation rates are influenced by either trait conservatism or trait divergence. The findings showed that smaller hummingbirds with shorter bills, living at higher elevations and experiencing greater temperature ranges, exhibit faster speciation. Additionally, speciation was found to increase with rates of divergence in niche traits, but not in morphological traits.

Summary: The biota of Sulawesi is known for its unique species and diversification. In this study, the diversification history of Sulawesi flying lizards, an endemic group to Sulawesi, was explored using a geological framework. The analysis revealed that there are more Draco species in Sulawesi than previously thought, with cryptic and arrested speciation events and ancient hybridization affecting the phylogenetic analyses. The colonization of Sulawesi by the common ancestor of the Draco lineatus Group occurred around 11 million years ago, followed by radiations and dynamic species interactions.

Summary: Insular communities are highly susceptible to human-induced extinctions and introductions, which can affect seed dispersal and lead to ecological shifts and co-extinction cascades. In a study conducted in Mauritius, an oceanic island with a well-studied history of species introduction, researchers found that while there were losses of interaction partnerships due to native species extinctions, there were also gains of interactions with introduced species. However, closer examination revealed that these interactions were predominantly with seed predators, indicating that restoration of seed dispersal functionality in this novel plant-frugivore community is unlikely.

Summary: This study demonstrates that mechanistic models based on functional traits can accurately identify areas at risk of invasion by non-native birds in Europe. Predicting potential invasive distribution ranges has significant uncertainties, but using ecophysiological mechanistic models can determine the true extent of the geographical area at risk. Mechanistic predictions, which can identify tolerable climates outside of species' current niches, are valuable for informing policy and management strategies to prevent the escalating impacts of invasive species.

Summary: Using whole-genome sequence data, this study reconstructs the demographic histories of 263 bird species over the past million years and identifies networks of interacting morphological and life history traits associated with changes in effective population size (Ne) in response to climate warming and cooling. The results highlight the direct and indirect effects of key traits representing dispersal, reproduction, and survival on long-term demographic responses to climate change, thus identifying the traits most likely to influence population responses to ongoing climate warming.
