Background Understanding how species biology may facilitate resilience to climate change remains a critical factor in detecting and protecting species at risk of extinction. Many studies have focused on the role of particular ecological traits in driving species responses, but less so on demographic history and levels of standing genetic variation....

Full-text available
Recent observations have shown the atmospheric greenhouse gas methane (CH 4 ) is consumed by microorganisms (methanotrophs) in caves at rates comparable to CH 4 oxidation in surface soils. Caves are abundant in karst landscapes that comprise 14% of Earth’s land surface area, and therefore may represent a potentially important, but overlooked, CH 4...
Article
Full-text available
Distribution of Earth’s biomes is structured by the match between climate and plant traits, which in turn shape associated communities and ecosystem processes and services. However, that climate–trait match can be disrupted by historical events, with lasting ecosystem impacts. As Earth’s environment changes faster than at any time in human history,...
Article
Full-text available
Recent advances in ecology and biogeography demonstrate the importance of fire and large herbivores – and challenge the primacy of climate – to our understanding of the distribution, stability, and antiquity of forests and grasslands. Among grassland ecologists, particularly those working in savannas of the seasonally dry tropics, an emerging fire–...

Aim Marine vertebrates play key functional roles on reef ecosystems. Despite their phylogenetic distance, different vertebrate lineages could play similar functions on reefs, which has been overlooked by current research on marine functional biogeography. We provide the first comprehensive assessment of the functional structure and inventory of eco...
Article
Full-text available
Global biodiversity is organised into biogeographic regions that comprise distinct biotas. The contemporary factors maintaining differences in species composition between regions are poorly understood. Given evidence that populations with sufficient genetic variation can adapt to fill new habitats, it is surprising that more homogenisation of speci...

Climate change (CC) is expected to negatively impact global biodiversity and ecosystems, resulting in profound ecological impacts and placing complex networks of biological interactions at risk. Despite this worrying scenario, the existing knowledge deficiencies may be overcome with species distribution models (SDMs), providing estimates of the eff...

Context Species distribution modeling (SDM) is an integral tool for conservation, biogeography, and climate change biology. However, practioners have to choose from increasingly numerous SDM algorithms performing well under different conditions, including clade and resolution. Objectives To identify the most suitable SDM algorithms for trees, bird...

Multiple initiatives have called for large-scale representative networks of marine protected areas (MPAs). MPAs should be ecologically representative to be effective, but in large, remote regions this can be difficult to quantify and assess. We present a novel bioregionalization for the Southern Ocean, which uses the modelled circumpolar habitat im...

The symbiotic relationship between corals and symbiodiniaceans can favor reef formation, but is easily rupted when these organisms are exposed to thermal anomalies. Here, we assessed the ITS2 rDNA phylotype diversity of dominant Symbiodiniaceae lineages associated with the hydrocoral Millepora alcicornis and investigated host–symbiont distribution...

Edge effects are caused by the penetration of abiotic and biotic conditions from the nonforest matrix into forest interiors. Edge effects are particularly relevant to studies of lemur conservation biogeography due to the high levels of forest loss and fragmentation on Madagascar. Moreover, climatic seasonality has influenced many aspects of lemur e...

Thermokarst lakes are widely distributed in cold regions as a result of ice-rich permafrost thaw. Disentangling the biogeography of abundant and rare microbes is essential to understanding the environmental influences, assembly mechanisms, and responses to climate change of bacterial communities in thermokarst lakes. In light of this, we assessed t...

The aquatic microfauna of Africa is poorly characterized, especially in the case of planktonic rotifers inhabiting waterbodies other than large lakes. In addition, little is known about factors that structure these communities. Here, we assessed the roles of climatic region, habitat type, macrophyte abundance, and a suite of abiotic environmental f...

The gigantea species group of the genus Colocasiomyia de Meijere (Diptera: Drosophilidae) is among the four aroid-breeding species groups in this genus; however, it differs from the remaining three groups in the host use: all the flies in this group use plants from the subfamily Monsteroideae instead of from the subfamily Aroideae. So far, we have...

The Amazon region is a mosaic of distinct areas of endemism (AoE), each with its evolutionary relationships and biotic assemblages. Among them, the Tapajós AoE is one of the least sampled, and it has been identified as one of the regions with the lowest conservation value. Here we provide a checklist of small mammals based on field and molecular-ba...

Background and aims – The genus Impatiens is known for its enormous convergent phenotypic adaptation, with similar floral traits having independently evolved in distantly related lineages. The large functional convergence of Impatiens flowers causes a high degree of homoplasy for several phenotypic characters resulting in increased difficulties to...

Religion et Science se sont retrouvées en conflit sur le sujet de l'évolution dans la deuxième moitié de XIX e siècle et la première du XX e. Contrairement à certaines idées reçues, c'est grâce à une activité de recherche naturaliste en interne que l'Église a adopté la maxime « la théorie de l'évolution est plus qu'une hypothèse ». Cette activité d...

Full-text available
Species richness varies immensely around the world. Variation in the rate of diversification (speciation minus extinction) is often hypothesized to explain this pattern, while alternative explanations invoke time or ecological carrying capacities as drivers. Focusing on seed plants, the world’s most important engineers of terrestrial ecosystems, we...

Historical processes like speciation, extinction and historical dispersal are the ultimate factors generating and maintaining biodiversity. Therefore, understanding how these factors affect the distribution of biodiversity is of great importance. To do so, it is necessary to integrate information from ancestral state reconstructions and current spe...

African wild pigs have a contentious evolutionary and biogeographic history. Until recently, desert warthog (Phacochoerus aethiopicus) and common warthog (P. africanus) were considered a single species. Molecular evidence surprisingly suggested they diverged at least 4.4 million years ago, and possibly outside of Africa. We sequenced the first whol...

Light, essential for photosynthesis, is present in two periodic cycles in nature: seasonal and diel. Although seasonality of light is typically resolved in ocean biogeochemical–ecosystem models because of its significance for seasonal succession and biogeography of phytoplankton, the diel light cycle is generally not resolved. The goal of this stud...

Dense blooms of filamentous cyanobacteria are recurrent phenomena in the Baltic Sea, with occasional negative effects on the surrounding ecosystem, as well as on tourism, human health, aquaculture, and fisheries. Establishing a climate service is therefore suggested; including multi-method observations of cyanobacteria biomass, biodiversity, and bi...

Factors shaping the distribution and abundance of species include life‐history traits, population structure, and stochastic colonization–extinction dynamics. Field studies of model species groups help reveal the roles of these factors. Species of Caenorhabditis nematodes are highly divergent at
