Abstract	Insect populations have become increasingly threatened during the last decades due to climate change and landuse intensification. Species characteristics driving these threats remain poorly understood. Trait-based analyses provide a straight-forward approach to gain a mechanistic understanding of species' extinction risk, guiding the development of conservation strategies. We combined morphological traits and phylogenetic relationship for 332 European species of butterflies and 115 species of odonates (dragon and damselflies) to model their red list status via phylogenetically controlled ordered logistic regression. We hypothesized that extinction risk increases with increasing body volume and wing area, decreasing range size, and is larger for brighter species. All investigated traits exhibited a strong phylogenetic signal. When controlling for phylogenetic relationship, we found that extinction risk of butterflies increased with decreasing range size. The extinction risk of odonates showed no relationship with the selected traits. Our results show that there is no universal trait defining the extinction risk of our investigated insect taxa. Furthermore, evolutionary history, measured as the phylogenetically predicted part of our analyzed traits, poorly predicted extinction risk. Our study confirms the focus of conservation measures on European butterfly species with small range sizes.

Abstract	AIM: Biogeographical inference and assessments of species' threat status and trends depend on comprehensive information on the current geographical distribution of species. Even country‐level presences remain poorly known for many insect species and consistent global overviews for those species are missing. Here we integrate information from literature checklists, point occurrences, and identify potential species range gaps to provide a database of country‐level checklists of dragonfly and damselfly species and a useful baseline for global biogeographical assessment and for assessing remaining gaps in taxonomic and spatial knowledge. LOCATION: Global. TAXON: Odonata (damselflies and dragonflies). METHODS: Our database of checklist information contains country‐level species distribution information from 491 literature sources, with a focus on checklist data from 1990 to 2021 to reflect the present taxonomic and country boundaries. Additionally, we apply a novel method to interpolate potential species–country combinations missing from the literature and point data by generating a list of species present in >50% of the surrounding countries. RESULTS: Of the 6,322 globally recognized odonate species, taxonomically harmonized literature checklist records and quality‐controlled point occurrence data address 6,076 and 4,170 species, respectively. Our compilation provides a total of 31,569 unique species–country combinations, with 23,239 uniquely provided by literature checklist and 2,031 point occurrence data, respectively. MAIN CONCLUSIONS: This odonate country checklist dataset provides a resource for scientists and conservation practitioners to examine questions related to baseline odonate species richness, distributions, regional conservation, and gaps in taxonomic and spatial data coverage. The combined literature and point occurrence country‐level information provide the most comprehensive data available to date on the global distribution of Odonata. Our results show that checklist and point occurrences are concordant in well‐studied regions and that literature data are of complementary value in tropical and species‐rich countries.

Abstract	MOTIVATION: Insects provide vital ecological functions and account for over half of all described species. An at least basic understanding of their geographical distributions is key for addressing a range of central ecological and evolutionary questions and to inform conservation. However, even for popular groups, such as butterflies, the knowledge of species’ distributions at global scale remains highly incomplete. To address this information gap, we present a data product of comprehensive country‐level occurrences for the 19,327 accepted species of extant butterflies. This compilation is based on a quality‐controlled combination of 165 literature sources and publicly available occurrence records from Global Biodiversity Information Facility (GBIF), harmonized to a global master taxonomy, and constitutes 159,659 (87,506 unique) species–country combinations. We developed a protocol for the integration of country‐level information from literature into the process of cleaning/validating species point occurrence records that facilitates dynamic updates of these country‐level checklist data. Such occurrence records are available for less than 54% of the species, with an apparent bias towards temperate regions and taxa. We use this combined database for a global assessment of the geographical variation in the diversity of butterflies, including an analysis of latitudinal gradients in the species richness—the first undertaken at this higher resolution. Country‐level richness decreases from the equator to the poles, both with and without control for country sizes. The presented data and analyses highlight the potential of leveraging multiple types of distribution information, particularly for taxa with limited data and their incorporation in ecological and conservation analysis. Our database and associated workflows provide a basis for an improved biogeographical understanding and conservation of insect biodiversity. MAIN TYPES OF VARIABLES CONTAINED: Country‐level occurrences and their sources. SPATIAL LOCATION AND GRAIN: Global, 256 countries. TIME PERIOD AND GRAIN: 1861 to 2021. MAJOR TAXA AND LEVEL OF MEASUREMENT: 19,191 accepted species of extant butterflies. SOFTWARE FORMAT: .csv, .shp.

Abstract	AIM: So far, latitudinal body size clines have been discussed primarily in the context of thermoregulation, sensu Bergmann. However, body size patterns are ambiguous in ectotherms, and this heterogeneity remains poorly understood. We tested whether Bergmann's rule and the resource availability rule, which states that energetic requirements determine species body size, apply to damselflies and dragonflies (Odonata). Furthermore, we hypothesized that the contrasting effects of thermoregulation and resource availability (e.g., productivity) can obscure the overall gradient in body size variation. LOCATION: Global. TIME PERIOD: Contemporary. MAJOR TAXA STUDIED: Odonata. METHODS: Using data for 43% of all odonate species described so far, we tested our hypotheses in phylogenetically and spatially comparative analyses at assemblage and species levels. For the distribution data, we integrated expert range maps and ecoregional ranges based on all available occurrence records. To distinguish between long‐term and evolutionarily recent responses of environmental drivers in body size, we constructed a phylogenetically informed classification of all odonate species and decomposed the body size into its phylogenetic and specific components for our subset of species. RESULTS: We documented a weak positive relationship between body length and latitude but found strong and contrasting effects for temperature between dragonflies and damselflies and consistent positive effects for productivity that explained 35–57% of body size variation. Moreover, we showed a strong phylogenetic signal in sized‐based thermoregulation that shaped the distribution of dragonflies, but not of damselflies. MAIN CONCLUSIONS: We concluded that temperature, productivity and conservatism in size‐based thermoregulation synergistically determine the distribution of ectotherms, while the taxon‐specific importance of these factors can lead to contrasting and weak latitude–size relationships. Our results reinforce the importance of body size as a determinant of species distributions and responses to climate change.

Abstract	Phenology, the seasonal timing of life events, is an essential component of diversity patterns. However, the mechanisms involved are complex and understudied. Body colour may be an important factor, because dark-bodied species absorb more solar radiation, which is predicted by the Thermal Melanism Hypothesis to enable them to thermoregulate successfully in cooler temperatures. Here we show that colour lightness of dragonfly assemblages varies in response to seasonal changes in solar radiation, with darker early- and late-season assemblages and lighter mid-season assemblages. This finding suggests a link between colour-based thermoregulation and insect phenology. We also show that the phenological pattern of dragonfly colour lightness advanced over the last decades. We suggest that changing seasonal temperature patterns due to global warming together with the static nature of solar radiation may drive dragonfly flight periods to suboptimal seasonal conditions. Our findings open a research avenue for a more mechanistic understanding of phenology and spatio-phenological impacts of climate warming on insects.

Abstract	Small-scale studies have shown that colour lightness variation can have important physiological implications in ectotherms, with darker species having greater heating rates, as well as protection against pathogens and photooxidative damage. Using data for 41% (3059) of all known frog and toad species (Anura) from across the world, we reveal ubiquitous and strong clines of decreasing colour lightness towards colder regions and regions with higher pathogen pressure and UVB radiation. The relative importance of pathogen resistance is higher in the tropics and that of thermoregulation is higher in temperate regions. The results suggest that these functions influence colour lightness evolution in anurans and filtered for more similarly coloured species under climatic extremes, while their concurrent importance resulted in high within-assemblage variation in productive regions. Our findings indicate three important functions of colour lightness in anurans - thermoregulation, pathogen and UVB protection - and broaden support for colour lightness-environment relationships in ectotherms.

Abstract	AIM: Forest relicts in the mountainous regions of Africa represent one of the most diverse ecosystems on our planet, but the processes that have generated this remarkable diversity are still poorly understood. We estimate divergence times for an endemic, flightless grasshopper family and reconstruct a potential scenario for their colonization of Africa to test the hypothesis that the diversity of these mountain‐top endemics has been generated by multiple fragmentations and reconnections of tropical rain forests in parallel with climatic fluctuations. LOCATION: Sub‐Saharan Africa. TAXON: Lentulidae (Orthoptera). METHODS: We inferred the phylogeny of 7 genera and 28 species of the Lentulidae based on COI, 16S and Histone 3 sequences by using a Bayesian approach and we also estimated divergence dates. Based on our molecular phylogeny as well as the available information on the relationship of six additional genera and local occurrence records for 120 lentulid species across Africa, we reconstruct a potential colonization scenario for most species of this group. RESULTS: Our findings indicate that the forest‐bound lentulids of East Africa represent a monophyletic group that originates from South Africa. We show that major splits in the phylogeny of the Lentulidae coincide with three known fragmentation events of the African rain forests (27, 16 and 9 Ma) and that lentulids subsequently diversified rapidly in parallel with the aridification and strong geological activity in East Africa. MAIN CONCLUSIONS: Our results corroborate the diversification patterns reported for several endemic African forest‐bound animal taxa at small scales and endemic African plant taxa at larger scales, highlighting the finding that much of the biodiversity presently found in the forest relicts of the Eastern Arc Mountains biodiversity hotspot has been generated by the interplay between humid periods that allowed the spread of forest‐bound lineages across Africa and periods of aridity‐driven isolation of forests and their associated fauna.

Abstract	Previous macrophysiological studies suggested that temperature-driven color lightness and body size variations strongly influence biogeographical patterns in ectotherms. However, these trait-environment relationships scale to local assemblages and the extent to which they can be modified by dispersal remains largely unexplored. We test whether the predictions of the thermal melanism hypothesis and the Bergmann's rule hold for local assemblages. We also assess whether these trait-environment relationships are more important for species adapted to less stable (lentic) habitats, due to their greater dispersal propensity compared to those adapted to stable (lotic) habitats.We quantified the color lightness and body volume of 99 European dragon- and damselflies (Odonata) and combined these trait information with survey data for 518 local assemblages across Europe. Based on this continent-wide yet spatially explicit dataset, we tested for effects temperature and precipitation on the color lightness and body volume of local assemblages and assessed differences in their relative importance and strength between lentic and lotic assemblages, while accounting for spatial and phylogenetic autocorrelation.The color lightness of assemblages of odonates increased, and body size decreased with increasing temperature. Trait-environment relationships in the average and phylogenetic predicted component were equally important for assemblages of both habitat types but were stronger in lentic assemblages when accounting for phylogenetic autocorrelation.Our results show that the mechanism underlying color lightness and body size variations scale to local assemblages, indicating their general importance. These mechanisms were of equal evolutionary significance for lentic and lotic species, but higher dispersal ability seems to enable lentic species to cope better with historical climatic changes. The documented differences between lentic and lotic assemblages also highlight the importance of integrating interactions of thermal adaptations with proxies of the dispersal ability of species into trait-based models, for improving our understanding of climate-driven biological responses.
