Abstract Paphiopedilum godefroyae is an orchid species endemic to southern Thailand, known for its diverse flowers. It spread across the Kra Isthmus and has three recognized varieties: P. var. ang-thong on eastern side, leucochilum western side. In this study, we investigated how acts as a barrier, affecting genetic makeup of these populations. We used double-digest restriction site-associated DNA sequencing (ddRAD-seq) analyse diversity structure among 111 samples. The analyses revealed two distinct groups corresponding east west coasts. populations showed higher less gene flow, while population displayed signs historical bottleneck reduced due natural human disturbances over past 1000 years. This study emphasized that significantly limits flow between limited dispersal ability hoverfly pollinators wind-dispersed seeds, influenced by seasonal monsoons, further affects flow. By contrast, varieties had more stable demographic histories. in population, resulting from recent bottlenecks geographical barrier restricting underscores need targeted conservation efforts. Given low strategies such rescue habitat restoration are essential enhance variability ensure long-term survival species.

Fire affects many critical ecological processes, including pollination, and effects of climate change on fire regimes may have profound consequences that are difficult to predict. Considerable work has examined pollinator diversity, but relatively few studies these interaction networks those pollinators other than bees. We the a severe wildfire hoverfly in Mediterranean island system. Using data collected over 3 consecutive years at burnt unburnt sites, we documented differences species abundance, functional traits, as well interactions with flowering plants. Hoverfly abundance richness peaked during first post-fire season (year 1), which coincided presence opportunistic species. Also year 1, pollination were larger, less specialized, more nested, modular (vs. unburnt) sites; furthermore, exhibited higher phylogenetic host-plant diversity. These declined next 2 years, sites converging similarity communities networks. While obtained provide clear timeline initial recovery, emphasize importance longer-term monitoring for understanding responses natural wildfires, projected become frequent destructive future.

Abstract Hoverflies (Syrphidae) are essential pollinators, and their severe decline jeopardizes invaluable contribution to plant diversity agricultural production. However, we know little about the dispersal abilities of hoverflies in urbanized landscapes, limiting our understanding spatiotemporal dynamics plant–pollinator systems reducing ability preserve biodiversity context global change. Previous work has not addressed how urbanization affects functional connectivity whether is a factor population dynamics. In this study, investigated spatial genetic structure two nonmigratory species urban areas.

Abstract Long‐distance insect migration is poorly understood despite its tremendous ecological and economic importance. As a group, Nearctic hover flies (Diptera: Syrphidae: Syrphinae), which are crucial pollinators as adults biological control agents larvae, almost entirely unrecognized migratory examples of highly behavior among several Palearctic species. Here, we examined evidence mechanisms for four fly species ( Allograpta obliqua , Eupeodes americanus Syrphus rectus ribesii ) common throughout eastern North America using stable hydrogen isotope (δ 2 H) measurements chitinous tissue, morphological assessments, abundance estimations, cold‐tolerance assays. Although further studies needed, nonlocal isotopic values obtained from specimens collected in central Illinois support the existence long‐distance fall Eu. to lesser extent S. . Elevated during expected autumn period supports such behavior. Moreover, high phenotypic plasticity morphology associated with dispersal coupled significant differences between local suggest that exhibits unique suite traits decrease costs flight. Finally, compared ostensibly nonmigratory A. was less cold tolerant, factor may be Collectively, our findings imply occurs flies, but consider methodological limitations study addition potential consequences these novel findings.

Abstract Several hundred butterfly species show some form of migratory behaviour. Here we identify how the methodologies available for studying migration have changed over time, and document geographic taxonomic foci in study migration. We review publications on published six languages (English, Simplified Chinese, Traditional Japanese, Korean, Spanish), summarise butterflies has been studied, explore patterns knowledge base, outline key future research directions. Using English search keywords, found only 58 studies from Asia; however, after searching local languages, an additional 98 relevant studies. Overall, are mostly North America Europe. Most focus three species: monarch ( Danaus plexippus ), painted lady Vanessa cardui ) red admiral atalanta ). About 62% focused monarch, with nearly 50% mentioned a single paper. methods applied to ascribe status physiology, neurobiology, ecology migration; virtually all this is handful species. There remain hundreds which do not understand comprehensive seasonal pattern movement, flight destinations, wintering, or breeding grounds. A better understanding movement connectivity needed effectively conserve butterflies. It essential that becomes more geographically linguistically representative since migrants frequently cross political borders international cooperation necessary their conservation.

Abstract Insect migrants are hugely abundant and recent studies have identified Diptera as the major component of many migratory assemblages, often totalling up to 90% all individuals. Despite this, into their behaviour been widely eschewed in favour more ‘charismatic’ migrant insects such butterflies, dragonflies, moths. Here we review available literature on Dipteran migration identify 13 lines evidence that use determine behaviour. Using this approach, find species from 60 out 130 families show migration, with Syrphidae fulfilling 12 these criteria, followed by Tephritidae 10. In contrast groups, 22 fulfilled just two or fewer, underlining need for research characteristics groups. total, 622 were found (0.5% total count), a figure rising 3% Syrphidae, percentage mirrored other animal taxa noctuid moths, bats. Research was biased locations Europe (49% publications) while vast regions remain understudied, our flyways used across biogeographic realms. Finally, detail ecological economic roles how services being affected anthropogenic change through population declines phenological shifts. Overall, highlights little is known about vital may be health global ecosystems.

Hover flies (Diptera: Syrphidae) are an important group of insects that provide a multitude key ecosystem services including pollination and biological control, yet many their major life history traits not understood. Some Palearctic hover fly species known to migrate in response changing seasonal conditions, this behavior is almost entirely unrecognized Nearctic species. At least one species, Eupeodes americanus , partially migratory during autumn while Allograpta obliqua may be non‐migratory, but it unknown where these originate how far they travel. We examined natal origins two A. E. using stable hydrogen isotope (δ 2 H) measurements metabolically inactive tissues (wings legs) derive δ H isoscape. While was mostly local origin, several were sourced from northern latitudes the Midwestern United States Canada, representing travel distance up 3000 km likely seasonally favorable air currents. This phenomenon expected have ecological economic ramifications, especially realm plant ecology control.

Abstract Background Natural enemies are important in pest control. However, control by natural is hindered the migration of rice planthoppers. Therefore, comigration and interactions between Laodelphax striatellus (Fallén) Sogatella furcifera (Horváth) five predator species, Chrysoperla sinica Tjeder, Harmonia axyridis (Pallas), Episyrphus balteatus , Syrphus corollae (Fab.) Chrysopa pallens (Rambur) eastern Asia were investigated. Results From 2012 to 2021, patterns two planthoppers enemy species monitored suction trapping on Beihuang Island, Shandong Province, China. Both regularly comigrated from late April October each year. There significant interannual seasonal differences numbers migrating across this island. Simulated trajectories indicated different source areas for planthoppers, which mainly originated northeast, north east The biomass was significantly positively correlated with that ladybug H. all periods, ratio among months. A time‐lag effect seasons obtained when pests comigrated. Conclusion Migration coordinated East Asia.
