TLDR
The structure of assemblages of dung beetles as well as their species composition and diversity were compared between two sites on both sides of the Mediterranean Sea and it was demonstrated that autumn-winter was the most constraining season in FR.Abstract:
Quantification of the species richness and diversity is important when comparing sites; these variables are influenced by local and regional factors. The structure of assemblages of dung beetles as well as their species composition and diversity were compared between two sites on both sides of the Mediterranean Sea (France FR and Tunisia TN). From a total of 132 traps, 15,778 specimens were collected belonging to 86 species (46 in FR vs. 40 in TN). Species composition varied highly between FR and TN (only 10 species in common). The temporal occurrence of Aphodiidae and Scarabaeidae showed different patterns due to several factors: phenology of species, geographical distribution and local ecological requirements. When quantifying the beta diversity, the turnover of species was for almost cases higher within the same season than between seasons. Moreover, seasonal turnover was different at both sites. Evenness and rank-abundance analyses demonstrated that autumn-winter was the most constraining sea...read more

Spatial and Temporal Variation in Species Composition, Diversity, and Structure of Mediterranean Dung Beetle Assemblages (Coleoptera: Scarabaeidae) Across a Bioclimatic Gradient
TL;DR: Results indicate that there were no spatio-temporal patterns according to bioclimate, but the influence of local and regional factors predominates on the dung beetle assemblages distribution.

Temporal Segregation between Dung-Inhabiting Beetle and Fly Species.
TL;DR: Season is the main temporal axis separating ecologically similar species of dung-inhabiting insects in temperate habitats, while succession aggregates species that may have similar environmental tolerances (to e.g. dung moisture).

Dung beetles (Coleoptera: Scarabaeidae) utilizing water buffalo dung on the Black Sea coast of Turkey

TL;DR: In the RAMSAR-listed wetland system of the Kizilirmak Delta of Turkey's central Black Sea coast, seasonal grazing by domesticated water buffalo produces plentiful dung from April to November, suggesting a more appropriate dung moisture regime over time that favors successful breeding on the sand.

Dung Beetle (Coleoptera: Scarabaeidae) Abundance and Diversity at Nature Preserve Within Hyper-Arid Ecosystem of Arabian Peninsula
TL;DR: Dung beetle abundance was positively correlated with the normalized difference vegetation index and two clusters of species phenology were apparent, a summer-active group and those not active during the summer months, which may enhance the understanding of dung beetle ecology in the rawdhat network within hyper-arid ecosystems of Arabian Peninsula.

Between locality variations in the seasonal patterns of dung beetles: the role of phenology in mitigating global warming effects
TL;DR: This work states that global warming may especially affect ectothermic insect species, making it necessary to forecast the capacity of these species to cope with climatic changes.

Ecological Diversity and its Measurement
TL;DR: In this paper, the authors define definitions of diversity and apply them to the problem of measuring species diversity, choosing an index and interpreting diversity measures, and applying them to structural and structural diversity.

Diversity in tropical rain forests and coral reefs.
TL;DR: The commonly observed high diversity of trees in tropical rain forests and corals on tropical reefs is a nonequilibrium state which, if not disturbed further, will progress toward a low-diversity equilibrium community as mentioned in this paper.

Quantifying biodiversity: procedures and pitfalls in the measurement and comparison of species richness
TL;DR: A series of common pitfalls in quantifying and comparing taxon richness are surveyed, including category‐subcategory ratios (species-to-genus and species-toindividual ratios) and rarefaction methods, which allow for meaningful standardization and comparison of datasets.

Community Diversity: Relative Roles of Local and Regional Processes
TL;DR: Observations suggest that regional and historical processes, as well as unique events and circumstances, profoundly influence local community structure and ecologists must broaden their concepts of community processes and incorporate data from systematics, biogeography, and paleontology into analyses of ecological patterns and tests of community theory.
