Relationship between the Decay Types of Dead Wood and Occurrence of Lucanid Beetles(Coleoptera:Lucanidae)

Influence of harvest gaps and coarse woody material on click beetles (Coleoptera: Elateridae) in Maine’s Acadian forest

“…As a result, there tended to be different species assemblages in logs of increasing sizes. A positive relationship between CWM diameter and species richness and abundance has been found in other studies (Jonsell et al 1998;Grove 2002;Hammond et al 2004; but see Araya 1993). In this study, although click beetle diversity decreased with increasing CWM diameter, all other measures increased with increasing log diameter.…”

Seedling regeneration on decayed pine logs after the deforestation events caused by pine wilt disease

“…Note that data of SHB was of 2003-2011 and of YMS was of 1994-2009. binary data, regardless of wood mass occupied by certain decay types. In this study, decay types were classified according to the macroscopic criterion of Araya (1993) as follows: Brown rot appears reddish-brown and easily breakable into cubical fragments, white rot appears whitish and bleached (yellowish-or grayish-white) and breakable into fibrous fragments, and soft rot appears dull-grey to brown with a mud-like surface. Details for decay type occurrence have been published in another paper (Fukasawa 2015a).…”

Implications of Wood Collecting Activities on Invertebrates Diversity of Conservation Areas

“…With such a high number of invertebrates species recorded and the wide variety of taxa found to be associated with deadwood, it is obvious that different tree species, although in different stages of their developments serve as a host to a diversity of invertebrate species (Saniga & Schütz, 2001). The fact that each stage of the tree is associated with a particular community of invertebrates (Araya, 1993;Bennett et al, 1994), indicates that a thorough investigation of the role and contribution of deadwood to the conservation of biodiversity needs to be investigated further to determine the other cryptic implications of collecting deadwood on biodiversity of conservation areas. What this chapter highlights which is of critical importance in respect to wood inhabiting invertebrates and the conservation of invertebrate diversity through maintenance of deadwood in conservation areas, is that some invertebrates are distinctly characterized of and limited to the habitat that is only provided by deadwood (Brues, 1920;Deyrup, 1976).…”

“…This oversight is despite the well-recognized fact that the presence of wood-inhabiting organisms in deadwood attracts other organisms that are either predators of these organisms or their larvae (Fager, 1968;Harmon et al, 1993). This relationship has long been recognized and appreciated by entomologists and has generated some interest in research and management of biodiversity associated with deadwood Fager, 1968;Käärik, 1974;Deyrup, 1981;Araya, 1993;Bennett et al, 1994;Lachat et al, 2006). Such plant-animal interactions has been identified as one of the dominant biotic interactions Farrell et al, 1992) that sustains much of the terrestrial faunal diversity (Samways, 1993) through the support of ecological interactions that exist among terrestrial living organisms.…”
