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.

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.

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.
