We evaluated short- (among months within-years) and long-term (between 1999-2000 2016-2017) temporal patterns of taxonomic functional β- diversity (and its components substitution gain/loss) dung beetle assemblages in forest fragments pastures the Los Tuxtlas Biosphere Reserve (LTBR). Habitat type affected dissimilarity richness difference component, with average values being respectively 1.42 1.56 times higher than fragments. Only habitat was important for richness, 1.93 1.69 2016-2017, respectively. Pastures were taxonomically functionally poorer but also more temporally dynamic both within-year between-years. is a determining factor dynamics, presenting stable cattle pastures.

Differential response of fire on the community dynamics of five insect taxa in a tropical mountaintop forest archipelago

Ecology and Evolution, Год журнала: 2023, Номер 13(12)

Abstract The Earth's most diverse group of organisms is facing an imminent crisis, as recent investigations suggest a remarkable decline in insect diversity. Within this context, altimontane forest islands might emerge important refuges holding invaluable diversity species that would be doomed to disappear. Here, we aimed examine the impact fire on temporal variation ant, bee, butterfly, dung beetle, and wasp communities natural highly threatened islands. We predicted incidence increase structure these insects' over time. Furthermore, each taxon respond accordingly their ability move between (i.e., vagility). sampled five bioindicator taxa rainy seasons 2014, 2015, 2018, 2020 within 14 southeast Brazil. assessed (presence/absence) occurrence island toward end dry season sampling year. found influence composition changes time (temporal β ‐diversity) less vagile groups: ants, beetles.

Microhabitat and seasonal influence on bess beetle (Coleoptera: Passalidae) assemblage in Altitudinal Atlantic Forest

Austral Entomology, Год журнала: 2024, Номер 63(3), С. 393 - 405

Опубликована: Авг. 1, 2024

Abstract Understanding the spatiotemporal distribution of diversity has been a significant challenge in field conservation biology. Presently, there exists limited understanding spatial passalid beetles within decomposing logs, as well their microhabitats such cortex, heartwood and trunk–soil interface. Moreover, is scarcity studies that delve into temporal patterns beetles. We evaluate effect seasons year on an Altitudinal Atlantic Forest. More specifically, effects period were analysed assemblage scale population structure scale. Collections actively conducted monthly, during dry rainy seasons, distinct logs (tree interface) sampled. discovered galleries 235 housing total 785 individuals representing nine species across six genera two tribes. Within three examined microhabitats, cortex harboured majority individuals. In contrast, interface microhabitat displayed reduced abundance absence indicator species, exhibiting community compared with others. The season stood out greater number individuals, underscoring influence precipitation activity this study. Our study contributes to ecological dynamics these insects evaluating resilience current landscape transformations planet.

The Impact of Eucalyptus and Pine Plantations on the Taxonomic and Functional Diversity of Dung Beetles (Coleoptera: Scarabaeidae) in the Southern Region of Ecuador

Biology, Год журнала: 2024, Номер 13(10), С. 841 - 841

Опубликована: Окт. 19, 2024

This study sheds light on the complex relationship between land use, biodiversity, and functional traits of dung beetles in Ecuador. The results indicate that richness abundance vary across different uses regions, with forests generally having a positive impact, while eucalyptus pine plantations have negative effect certain areas. Specific indicator species, such as

This study sheds light on the complex relationship between land use, biodiversity, and functional traits of dung beetles in Ecuador. The results indicate that richness abundance vary across uses regions, with forests generally having a positive impact eucalyptus pine plantations negative effect certain areas. Specific indicators, such as Homocopris buckleyi for forest areas Onthophagus curvicornis plantations, have been identified. also found diversity analysis, based morphological traits, indicated biomass, pronotum width, head elytra length, were significant contributors to differences beetle communities highlights potential conservation value modified habitats importance considering both taxonomic when assessing use ecosystem services provided by beetles. It underscores refuges conducting long-term assessments understand biodiversity changes over time.
