Seasonality in the dung beetle community in a Brazilian tropical dry forest: Do small changes make a difference?

Medina AM, Lopes PP - J. Insect Sci. (2014)

Bottom Line: Dry-season samples (EDS and LDS) had lower richness, with no significant difference between the dry seasons.Species composition changes were found in non-metric multidimensional scaling and sustained by analysis of similarity.As in other tropical dry forests, although to a lesser extent, the dung beetle community of this fragment responded to rainfall seasonality with changes in species composition and reduced species richness.

f02_01: Rank species abundance plots for dung beetle assemblages at four different moments: early dry season (EDS), late dry season (LDS), early wet season (EWS) and middle wet season (MWS).

Mentions: A total of 1,352 Scarabaeinae individuals were collected, belonging to 15 species and 8 genera (Table 1). Dichotomius aff. laevicollis Felsche (Coleoptera: Scarabaeidae) was the most abundant species, representing 73.89% of total individuals, followed by Canthon rutilans Laporte with 14.35%. Other species were each responsible for less than 5% of relative abundance. Species typical of Brazilian tropical dry forests, such as Deltochilum verruciferum Felsche and Coprophanaeus pertyi Olsoufieff (Caatinga) were recorded. However, species previously only recorded in Atlantic forest also were found, such as Canton stage Pereira and Canthidium sp 2. The rank dominance curves for the four sampling seasons were very similar (Fig. 2), although there was an increase in the abundance of Canthon rutilans in the late dry season.
