Beetle Species–Area Relationships and Extinction Rates in Protected Areas

The species–area relationship (SAR, i.e., the increase in species richness with area) is one of the most general ecological patterns. SARs can be used to calculate expected extinction rates following area (habitat) loss. Here, using data from Italian reserves, extinction rates were calculated for beetle groups with different feeding habits: Carabidae (terrestrial predators), Hydradephaga (aquatic predators), coprophagous Scarabaeoidea (dung feeders), phytophagous Scarabaeoidea (herbivores), and Tenebrionidae (detritivores). The importance of other factors besides area (namely latitude and elevation) was investigated. Reserve area was recovered as an important predictor of species richness in all cases. For Carabidae, Hydradephaga, and Tenebrionidae, elevation exerted a negative influence, whereas latitude had a negative influence on coprophagous Scarabaeoidea and Tenebrionidae, as a consequence of current and historical biogeographical factors. Extinction rates were higher for dung beetles, due to their dependence on large grazing areas, and Tenebrionidae, due to their low dispersal capabilities. The lower extinction rates predicted for Carabidae, phytophagous Scarabaeoidea, and Hydradephaga can be explained by their higher dispersal power. If other variables besides area are considered, extinction rates became more similar among groups. Extinction rates by area loss are always relatively low. Thus, in reserves with few species, many local extinctions might be unnoticed.

“…Consequently, D. italicus was reported as Pycnomerus italicus [9]. Recently, P. italicus was found in Basilicata in the Policoro wood, in Mount Vulture, and in the territory of Monticchio lakes, as well as in the Central Lucan Apennines, the Pollino Massif (Basilicata and Calabria), and the Aspromonte Massif (Calabria) [17]. This saproxylic species is associated with the dead wood of old-growth coniferous forests [12].…”

Pycnomerus italicus (Ganglbauer, 1899) (Coleoptera: Zopheridae), a saproxylic beetle endemic to Italy, is listed as “endangered” in the Red List of Italian Saproxylic Beetles. In 2021, during an entomological survey, 49 adults of this species were found in the Riserva Naturale Biogenetica Marchesale, Calabria, Southern Italy. The species was found in medium and high-quality habitats where a large number of fallen trunks of Abies alba Mill. 1759 (Pinales: Pinaceae) were present. On the same decaying trunks where P. italicus was found, larvae and/or adults of other three species of saproxylic beetles were detected. Although most aspects of the biology and ecology of P. italicus are still unknown, the presence of this endemic species in the Riserva Naturale Biogenetica Marchesale is interesting because this reserve and other humid forest environments in Southern Italy could be relevant refuges not only for this species but also for other endangered saproxylic beetles. These areas should be protected with appropriate forest-management techniques.

“…These references were checked to extract occurrence records from Italian preserved areas. This led to the selection of 18 reserves or reserve assemblages, since contiguous reserves were considered to a be a single reserve [37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54] (Figure 1, Table 1). All selected reserves were the object of intense sampling, in most cases through several years or even decades of insect collection, by expert taxonomists using a variety of sampling techniques.…”

The species-area relationship (SAR), the latitudinal gradient, the peninsula effect, and the elevational gradient are widespread biogeographical patterns. Using data from Italian reserves, these patterns were tested for tenebrionids and used as a framework to calculate expected extinction rates following area loss. Area was an important determinant of overall tenebrionid species richness, but not for xylophilous and endemic species. Thus, focusing on reserve areas is not the best approach for conserving insects with specialised ecology and restricted distribution. In general, species richness declined northwards, which contrasts with the peninsula effect, but conforms to the European latitudinal pattern observed in most taxa because of current and past biogeographical factors. Minimum elevation had an overall negative influence, as most tenebrionids are thermophilic. However, xylophilous tenebrionids, which are mainly associated with mesophilic forests, did not decline northwards, and were positively influenced by higher elevational ranges that allow more forms of vegetation. SAR-based extinction rates reflect species dispersal capabilities, being highest for geophilous species (which are mainly flightless), and lower for the xylophilous species. Extinction rates based on multiple models indicate that the use of area alone may overestimate extinction rates, when other factors exert an important role in determining species richness.
