“…Furthermore, there is some evidence that some taxa show differences between geographic ranges. In the United Kingdom, 60% of carabid species are nocturnal and 20% diurnal (Luff, 1978), whereas in a tropical dry forest in Colombia, 80% of grounddwelling Carabidae are nocturnal and 13.3% show both diurnal and nocturnal activity (Ariza et al, 2021). This may explain, in part, the differences between the results of several studies.…”

Diel activity is one main feature of animal‘s behavior and is often an intrinsic trait characterizing distinct taxonomic groups. Abiotic conditions such as temperature may influence the diel activity patterns of arthropod communities associated with a particular ecosystem or habitat. Similarly, biotic factors, such as resource availability, affect arthropod activity. In addition, diel activity is thought to be an important factor in niche partitioning of arthropod communities. As part of a larger beetle survey in a lowland tropical rainforest in southern Venezuela, I analyzed the diel activity of an arboreal beetle community collected from 23 canopy-tree species over a cumulative year. Diel activity was observed in 535 beetle species, comprising 5,948 individuals, using a canopy crane installed in the study area. Of the 535 beetle species, 198 (37%) showed diurnal activity, and 281 (52.5%) showed nocturnal activity. In contrast, the proportions of nocturnal (n = 2,024, 34%) and diurnal (n = 1,983, 33.3%) individuals were balanced. Most of the observed beetles occurred only during the activity phase in their host trees. This particularly applies to extrafloral nectary- and flower-visiting beetle species. Flowering trees attracted different proportions of diurnal and nocturnal species according to flowering syndrome, whereas extrafloral nectaries were mainly visited at night. Thus, the beetle communities associated with single tree species showed distinct compositions of nocturnal and diurnal species.

“…Effects of climate change related to the El Niño/ southern oscillation (ENSO) are a major pressure on tropical biomes in Southern Africa (Kirichenko-Babko et al 2020; Ariza et al 2021). The increase in long-lasting periods of drought, along with more erratic tropical rainfalls, may affect African landscapes vulnerable to climate aridi cation, such as the savannas in Mozambique (Engelbrecht et al 2007; Massad and Castigo 2016; Mbokodo et al 2020).…”

In the aftermath of the 2019’ tropical cyclones Idai and Kenneth, we assessed the Caraboidea communities of Gorongosa National Park (GNP) in Mozambique. Influence of the wet season, after a long period of drought, was evaluated on alpha and beta diversity of Caraboidea in the main habitat types of the park: miombo forests, mixed forests, transitional forests, and grasslands (open savannas). Caraboid communities were sampled by pitfall traps set up in 25 sites of each habitat type along three sampling periods, comprising the transition of dry season to the wet season. After the first rainfall, an increase in alpha diversity was observed across GNP habitats, particularly in grasslands. Higher values of beta diversity were observed between the dry and wet seasons, particularly in grasslands. In contrast, dissimilarities in caraboid communities between seasons were not significant in the transitional forests. A higher proportion of xerophilous species, with smaller body size and higher dispersal ability (winged species) was found in grasslands whereas bigger sized and more moisture-dependent caraboid species were found in forested habitats, particularly mixed forests. Community body size in grasslands increased after the rainfall, partly due to the occurrence of caraboid species that were exclusive of forest habitats during drought. Transitional forests, as ecotone habitat areas, appeared to support grassland species during drought, serving also as a source of forests species that may colonize the open areas in the wet season. Hygrophilous forest species will probably be more threatened by climate aridification and future landscape changes due to climate change.

In the aftermath of 2019’ tropical cyclones Idai and Kenneth, we assessed ground beetle communities of the Gorongosa National Park (GNP) in Mozambique. The influence of habitat shelters, namely the buffering role of closed microhabitat conditions on Alpha diversity and community trait values during a long period of drought, was evaluated across the main habitat types of the park: miombo forests, mixed forests, transitional forests, and grasslands (open savannas). These habitat types comprised a distance gradient in relation to lake Urema, in the center of GNP. Miombo forests were farther from the lake while grasslands and transitional forests were in the floodplain area. Ground beetle communities were sampled using pitfall traps set up at 25 sites of each habitat type along an environmental gradient of tree canopy cover during the last twenty days of the dry season. Higher species richness of ground beetles was found in closed habitat shelters along the distance gradient to lake Urema. A higher functional diversity was also found along the canopy gradient, with larger sized and wingless species being more abundant in closed habitats than in open areas. This result highlights the crucial role of habitat closedness in the protection of sensitive ground beetles. In particular, the buffer effect of tree canopy and the protection of the understory plants and the litter layer was critical for the survival of hygrophilous species and will be key in conservation strategies to face climate aridification and habitat fragmentation.
