Abstract Continued and rapid development of urban environments presents many challenges to organisms living in around cities. Insects are among the most abundant diverse class animals but surprisingly little is known about how species respond urbanisation across clades with varying life histories, especially subtropics tropics. In this study, we sample insect abundance diversity an gradient a subtropical region assess impact on 43 phototactic insects representing eight distinct orders.

A comprehensive synthesis of dung beetle records (Coleoptera, Scarabaeidae, Scarabaeinae) from Sabah, Malaysia

Biodiversity Data Journal, Journal Year: 2024, Volume and Issue: 12

Published: Sept. 12, 2024

Dung beetles play key roles in terrestrial ecosystems, contributing to many important ecosystem process and functions, such as nutrient recycling, parasite control seed dispersal. Due their tight associations with mammals responses environmental change, they are also frequently used biological indicators. Despite importance, knowledge about dung Southeast Asia is limited. To address this information gap, we established a databasing project - "Mobilising data on ecologically insects Malaysia Singapore" funded by the Global Biodiversity Information Facility (GBIF). As part of project, compiled two extensive datasets sampling-event occurrence dataset taxonomic checklist for Sabah, Bornean Malaysia. The documents 2,627 unique sampling events 21,348 beetle records Sabah. includes 156 confirmed species 36 synonyms, totalling 192 records. These have been made open access through GBIF portal, which hope will enhance understanding taxonomy distributions Asia.

Identifying the Knowledge and Capacity Gaps in Southeast Asian Insect Conservation

Ecology Letters, Journal Year: 2024, Volume and Issue: 28(1)

Published: Dec. 31, 2024

Insects represent most of terrestrial animal biodiversity, and multiple reports suggest that their populations are declining globally due to anthropogenic impacts. Yet, a high proportion insect species remain undescribed limited data on population dynamics hamper conservation efforts. This is particularly critical in tropical biodiversity hotspots such as Southeast Asia. To identify knowledge capacity gaps Asian conservation, we performed quantitative review occurrence records, studies for the region global '#conservation' posts from Twitter. We found records increased over time, were dominated by butterflies. Overall, largely focused pest vector groups, ecology lacking many countries. Despite an increase local authorships funding sources majority these still located outside In posts, insects highly under-represented insect-related content was biased towards popular groups bees potential solutions address gaps, integrative taxonomic approaches, increasing regional collaborations public engagements.

Linnean and Wallacean shortfalls of Leptophlebiidae (Ephemeroptera: Insecta) in the Brazilian Amazon

Aquatic Conservation Marine and Freshwater Ecosystems, Journal Year: 2024, Volume and Issue: 34(5)

Published: May 1, 2024

Abstract One of the primary challenges in biodiversity conservation is limited knowledge taxonomy and geographical distribution species, particularly megadiverse regions such as Amazon In this context, present study aimed to mitigate Linnean Wallacean shortfalls within Family Leptophlebiidae (Ephemeroptera: Insecta) Brazilian Amazon, identify priority areas for conducting faunal inventories enhance taxonomic group. Utilizing both data collected state Pará, secondary compiled from literature on species occurring we employed Species Distribution Modelling with higher potential richness family. For data, 2,120 specimens were identified, representing 16 genera 28 species. Among analysed, 7 constitute new records Pará. Additionally, two genera, five six morphospecies significantly expanding landscape family state. Maps depicting generated indicated that states Pará western region Maranhão exhibit high richness, overlapping identified priorities inventories. represents a substantial advancement underscoring urgency research efforts group region. Furthermore, identification taxa emphasizes need ongoing collaborative shortfalls.

Long-term population dynamics of an endangered butterfly are influenced by hurricane-mediated disturbance

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2024, Volume and Issue: unknown

Published: July 16, 2024

Abstract Effective species conservation requires understanding an organism’s population dynamics and natural history, but long-term data are challenging to collect maintain. As a result, management decisions frequently made using short-term data, which insufficient accurately assess trends in most species. For less-studied taxa, including invertebrates, inadequate of life history also impedes efforts. Long-term studies highly valuable for improving target as they serve model other understudied We use mark-recapture collected over 35 years examine weather drivers patterns endangered butterfly, Schaus’ swallowtail ( Heraclides ponceana ), enhance our its history. show that the size butterfly was variable, ranging from under 100 10,000 individuals. Population is influenced by events previous year. lower immediately following high wind positively four prior, with notable increases tropical cyclone events.

Temperature niche and body size condition phenological responses of moths to urbanization in a subtropical city

Ecology, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 2, 2024

Abstract Urbanization in temperate climates often advances the beginning and peak of biological events due to multiple factors, especially urban heat islands. However, effect urbanization on insect phenology remains understudied more tropical areas, where temperature may be a weaker phenological cue. We surveyed moths across an gradient subtropical city weekly for year test how impervious surface canopy cover impact at caterpillar adult life stages. For macro‐moths, we also examine these effects vary with history traits. When pooling all individuals, found no proxy variables timing or phenology. At species‐specific level, macro‐moths is influenced by cover, which interacts two traits: niche body size. Cold‐adapted species delay abundance shaded sites, while warm‐adapted were not affected. Smaller species, associated lower dispersal ability, phenologically sensitive than larger bodied species. These results highlight importance within cities its interaction species' traits mediating moth systems.

Plant species richness, not hygrothermal stress, is the main predictor of gall‐inducing insect richness in Peruvian Amazon forests

Abstract Patterns of gall‐inducing insect diversity tend to be influenced by both habitat‐related and plant‐related characteristics. We investigated the distribution patterns galling insects in four vegetation types ( terra firme forest, white‐sand dry wet forest palm swamp forest) Peruvian Amazon test if gall (1) differs among different (2) depends on host plant richness. In total, we found 11,579 galls belonging 249 morphotypes, distributed across 30 botanical families 75 species. Among families, Fabaceae showed greatest richness morphotypes. that species was lower than forests, which can explained plants this type vegetation. However, no evidence greater xeric habitats (e.g., more mesic forest), contradicting hypothesis hygrothermal stress. also positively with abundance species, regardless type. Galling composition differed significantly between types, similarly floristic composition. Our findings show tropical rainforests are mainly Spanish is available online material.

Unravelling the factors that influence plant-insect interactions remains a fundamental concern in terrestrial ecology. In present study, we evaluated impact of varying degrees drying on cerrado areas adjacent to veredas species richness, abundance and composition insect herbivore fauna. Additionally, examined differences these impacts between various guilds (chewing sucker insects) developmental stages (adult immature insects). The research has been performed study located three Protected Areas Brazil. total, recorded 106 herbivorous insects across five orders (Coleoptera, Hemiptera, Hymenoptera, Lepidoptera, Orthoptera). Hemiptera Coleoptera stood out as with highest diversity individual numbers. Among families, Cicadellidae Curculionidae exhibited richness individuals. We found was higher wet zones (20.2 ± 6.5) compared dry (12.3 7.5), well (49.4 25.5) than (15.8 7.9). Whithin guilds, chewing (34.0 13.6) (16.3 14.8), but this difference not observed for sucking insects. Regarding stage, (10.4 5.0) (5.3 2.1), while adult did show studied zones. Furthermore, insects, trophic (chewers suckers) (adults insect) significantly differ among within veredas. According our findings, exhibit preference environments, which provide better conditions higher-quality food resources development reproduction.
