Abstract The vertical movement of seeds performed by dung beetles from the soil bank and in animal faeces influences seed germination temporal dynamic forest regeneration. While this process has been explored at community level, individual role species is less understood. Here, we investigated beetle size under experimental conditions. We experiments using a gradient sizes three artificial (plastic beads) two situations: inside (secondary dispersal) buried ground (soil bank). Through regression analysis, related size, initial position on to final their potential germination. For bank, upward exhumation were mainly medium large seeds, initially located shallower depths, with larger being primarily responsible for movement. downward was similar all sizes. In percentage small gradually increased while made main contribution seeds. Besides, an average maximum bury depth nearly 4 cm (the limit zone). relative depended interaction between Moreover, essential burying Southern Atlantic Forest.

Abstract In Western Norway, farmers have traditionally used fire as a management tool in coastal heathlands to enhance the fodder quality for livestock. Rotational prescribed burning increases landscape heterogeneity by creating mosaic of different regeneration stages heather. Ground beetle (Coleoptera: Carabidae) responses managed heathland already been studied, but less is known about other groups this system. We compared activity between patches mature and recently burnt heath, looking at diversity indices, species composition ecological preferences traits. Contrary previous studies, we did not find an increase beta after disturbance, found that offers micro-environmental conditions which enhanced sun-loving xerophilous species. also identified new indicator both pioneer heath five families: Carabidae, Staphylinidae, Curculionidae, Leiodidae, Scirtidae. was confirmed be efficient conservation specialists without affecting overall site. recommend use several taxa, traits assess impact monitor condition heathlands.

The functional space of an ecological community is not evenly filled by its species. Instead, it usually divided into areas high species density, where with common combinations traits are grouped rich clusters, while lower density poor clusters or isolated uncommon unique traits. Species whose differ from those the rest expected to play distinct roles and over-contribute ecosystem functionality. Sampling methods used characterize arthropod assemblages target subsets filter based on their traits, reducing probability detecting Consideration these particularly important for characterizing structure resilience communities inhabiting threatened ecosystems such as lowland Amazonian rainforests, in which dung beetles multiple commonly indicators.

Functional diversity approaches, which are based on an organism's trait pattern, of increasing interest in ecological studies. However, there no rules setting the number or kinds traits that should be assessed; hence, researchers left to make their own decisions this regard. Moreover, some cases, same could assessed using different procedures, making comparisons between studies potentially difficult. Such is case dung beetle body size. We found it was measured by eight methods literature. Using three scarabaeine species (Canthon quinquemaculatus Castelnau, Deltochilum komareki Balthasar, and Eurysternus parallelus Castelnau), measuring size (wet weight, dry wet weight × clypeal-pygidial length, pronotal-pygidial clypeal-elytral pronotal-elytral elytral width length) were compared determine if they equivalent. a Spearman correlation coefficient, not all measurement Wet least correlated with other methods. Hence, standardize future studies, suggested for use, also has advantage being easy method use. Standardization will allow more reliable accurate
