Molecular identification is increasingly used to speed up biodiversity surveys and laboratory experiments. However, many groups of organisms cannot be reliably identified using standard databases such as GenBank or BOLD due lack sequenced voucher specimens by experts. Sometimes a large number sequences are available, but with too errors allow identification. Here, we address this problem for parasitoids Drosophila introducing curated open-access molecular reference database, DROP (Drosophila...
Ecological communities face major challenges of biodiversity loss, invasive species, and warming due to human action. Factors that determine the dynamics, stability functioning network interacting species have been debated in ecology since its beginning as discipline. Community complexity dominant (keystone) proposed most relevant factors, however there is lack knowledge on how these factors will interact with invasion. To effect complexity, or invasion their combinations a food web we...
Suitable conditions for species to survive and reproduce constitute their ecological niche, which is built by abiotic interactions with conspecifics heterospecifics. Organisms should ideally assess use information about all these environmental dimensions adjust dispersal decisions depending on own internal conditions. Dispersal plasticity often considered through its dependence or conspecific density and, a lesser extent, reference the effects of heterospecifics, potentially leading...
Abstract Aim Ecological communities are assembled by regional and local processes. These processes select species through their traits, which tied to species' evolutionary history. A multifaceted approach, encompassing taxonomic, functional phylogenetic diversity can thus help us better understand community assembly. We asked what the relative importance of geography, climate soil parameters is in driving diversities at (alpha) larger scales (beta diversity). Location Atlantic Europe. Taxon...
Climate change is altering the relative timing of species interactions by shifting when first appear in communities and modifying duration organisms spend each developmental stage. However, community contexts, such as intraspecific competition alternative resource species, can prolong shortened windows availability may mitigate effects phenological shifts on interactions. Using a combination laboratory experiments dynamic simulations, we quantified how Drosophila-parasitoid differed with...
Abstract The relative importance of local‐ and landscape‐scale factors on butterfly diversity can depend the quality, management intensity landscape context habitat patches. This study aims to disentangle these local effects taxonomic functional composition communities within mosaic agricultural landscapes. We sampled butterflies in 144 grasslands 142 linear elements (road verges herbaceous strips between crops) three regions France. analysed how variables affected species richness,...
Global warming is expected to have direct effects on species through their sensitivity temperature, and also via biotic interactions, with cascading indirect species, communities, entire ecosystems. To predict the community-level consequences of global climate change we need understand relative roles both warming. We used a laboratory experiment investigate how affects tropical community three Drosophila hosts interacting two parasitoids over single generation. Our experimental design...
Classical theories predict that relatively constant environments should generally favour specialists, while fluctuating be selected for generalists. However, theoretical and empirical results have pointed out generalist organisms might, on the contrary, perform poorly under fluctuations. In particular, if generalism is underlaid by phenotypic plasticity, performance of generalists modulated temporal characteristics environmental Here, we used experiments in microcosms Tetrahymena thermophila...
Ecological communities are composed of many species, forming complex networks interactions. Current environmental changes altering the structure and species composition ecological networks, which could modify interactions, either directly or indirectly. To predict in functioning communities, we need to understand whether interactions primarily driven by network (i.e. topology) specific identities nodes). Yet, this partitioning effects is challenging thus rarely explored. Here disentangled...
Current global changes are reshaping ecological communities and modifying environmental conditions. We need to recognize the combined impact of these biotic abiotic factors on species interactions, community dynamics ecosystem functioning. Specifically, strength predator-prey interactions often depends presence other natural enemies: it weakens with competition interference or strengthens facilitation. Such effects multiple predators prey likely be affected by in environment, altering...

Climate change is altering the relative timing of species interactions by shifting when appear in a community and accelerating developmental rates. However, phenological shifts may be mediated through contexts, such as intraspecific competition alternative resource species, which can prolong otherwise shortened windows availability. Using combination laboratory experiments dynamic simulations, we quantified how effects Drosophila-parasitoid differed with concurrent changes temperature,...
Abstract Ecological communities are composed of many species, forming complex networks interactions. Current environmental changes altering community composition. We thus need to identify which aspects species interactions primarily driven by structure and identity predict in the functioning communities. Yet, this partitioning effects is challenging rarely explored. Here we disentangled influence co-occurring on outcome consumer-resource using a host-parasitoid system. used four modules that...
Abstract Current global warming trends are expected to have direct effects on species through their sensitivity temperature, as well biotic interactions, with cascading indirect species, communities, and entire ecosystems. To predict the community-level consequences of change we need understand relative roles both warming. We used a laboratory experiment investigate how affects tropical community three Drosophila hosts interacting two parasitoids over single generation. Our experimental...
