Abstract Diverse taxa have undergone phenological shifts in response to anthropogenic climate change. While such generally follow predicted patterns, they are not uniform, and interspecific variation may important ecological consequences. We evaluated relationships among species’ (mean flight date, duration of period), traits (larval trophic specialization, larval diet composition, voltinism), population trends a butterfly community Pennsylvania, USA, where the summer growing season has...
The European protected-area network will cease to be efficient for biodiversity conservation, particularly in the Mediterranean region, if species are driven out of protected areas by climate warming. Yet, no empirical evidence how change influences ecological communities nature reserves really exists. Here, we examine long-term (1998–2011/2012) and short-term (2011–2012) changes butterfly fauna Dadia National Park (Greece) revisiting 21 18 transects 2011 2012 respectively, that were...
Greece is a European hotspot for Orthoptera (378 species), yet it has been scarcely explored. We investigated the distribution and habitat preferences of species two endemic genera, Parnassiana Oropodisma, in montane ecosystems central Greece. conducted field surveys from 2021 to 2024 174 sites across seven mountains. The both genera preferred habitats above 1500 m, with species-specific microhabitat parameters: favored moderate slopes dense shrub cover, while Oropodisma substrates...
Urbanisation is transforming environments globally. The altered abiotic conditions and biotic interactions in urban habitats inflict divergent selection pressures on versus rural populations. Genetic drift may simultaneously be significant typically small A key question evolution whether genotypes have a single or multiple origins, but such assessments remain rare, precluding generalizations. We expect similar patterns species that share ecological traits, replicates are missing. To address...
Climate change has had strong impacts on biodiversity, including well-documented shifts in the distributions and phenology of species. Reductions body size represent a third pervasive biological response; it garnered significantly less attention despite great ecological relevance. Theoretical frameworks-the temperature-size rule, Bergmann's James's rule-predict that warmer temperatures are associated with smaller sizes ectotherms. In contrast, empirical evidence concerning this pattern is...
Because of its close ties to numerous ecological and life history characteristics, body size is regarded as one an organism's most important characteristics frequently considered a significant indicator fitness. According recent studies, ectotherms in particular, may see reduction with rising temperatures. How traits influence, however, shifts butterfly response environmental changes, particularly focusing on the effects temperature land use poorly studied. Using Generalized Additive Models...
Climate change has been reshaping natural communities by driving species to their ranges in response warming temperatures. In Switzerland, the rate of since 1950 approached nearly double global average, making these impacts important for community composition and ecosystem function. Using Community Weighted Length Index (CWLI) as body size estimator, previously extracted museum specimens, we studied two decades butterfly data that have inventoried Biodiversity Monitoring Switzerland program....
Abstract The application of complex network theory to community ecology has enabled quantification interactions among large suites species and clarified patterns structure across systems. Past analyses, however, have assumed that ecological networks are temporally static persistent spatially homogeneous, which could confound inference if vary over time space. To evaluate temporal spatial variation in mutualistic networks, therefore, we evaluated the consistency a nectarivory/pollination...
Abstract Inferring species' responses to climate change in the absence of long‐term time series data is a challenge, but can be achieved by substituting space for time. For example, thermal elevational gradients represent suitable proxies study phenological warming. We used butterfly from two Mediterranean mountain areas test whether mean dates appearance communities and individual species show delay with increasing altitude, an accompanying shortening duration flight periods. found 14‐day...
1. Insects undergo phenological change at different rates, showing no consistent trend between habitats, time periods, species or groups. Understanding how and why this variability occurs is crucial. 2. Phenological patterns of butterflies O rthoptera were analysed using a novel approach s tandardised major axis ( SMA ) analysis. It was investigated whether: (i) phenology (the mean date duration flight) changed from one survey (1998 1999 respectively) to another (2011), (ii) the rate which...
Abstract Orthoptera species are vulnerable to extinction on a global scale. Greece hosts 35% (380 species) of the European fauna with high degree endemic (37%) and threatened (37%). We sampled 46 plots (100 m 2 ) investigate distribution ecological requirement two Greek mountain red‐listed species: Parnassiana parnassica (Ramme, 1926; Orthoptera: Tettigoniidae; Critically Endangered [CR]) Oropodisma (Scudder, 1897; Caelifera; [EN]). Species had restricted geographical range, isolated...
Abstract Variation in pollinator foraging behavior can influence pollination effectiveness, community diversity, and plant–pollinator network structure. Although effects of interspecific variation have been widely documented, studies intraspecific are relatively rare. Sex‐specific differences resource use a strong potential source variation, especially species where the phenology males females differ. Differences may arise from encountering different flowering communities, sex‐specific...
Abstract As grassland ecosystems transform globally due to anthropogenic pressures, improvements in our understanding of the effect management on rare and threatened species such landscapes has become urgent. Although prescribed fire is a very efficient tool for habitat restoration endangered fire-adapted ecosystems, specific mechanisms underlying potential effects burning population dynamics butterfly host plants are poorly understood. We analyzed 12-year dataset (2004–2015), combining...
In response to the ongoing global extinction, conservationists must prioritize future conservation investments ensure that such measures are biologically effective and economically viable. To propose an plan for Orthoptera assemblages on Cyprus Island, we introduce Standardized Conservation Index (StCI), a biodiversity index accounting value (ci), presence, dispersal ability, endemism status of species. We evaluated effect eleven environmental variables StCI, ci, species richness...
