Response of ground beetle (Carabidae) assemblages to logging history in northern hardwood–hemlock forests

Effects of forest management on ground beetle diversity in alpine beech ( Fagus sylvatica L.) stands

“…We detected a positive response of several diversity variables to CWD cover or volume, herb cover, and standard deviation of tree diameter distribution. In a similar study, coarse woody debris, snag volume, gap area, understory vegetation and forest floor depth were all critical in structuring beetle communities (Latty et al, 2006). Volume or cover of coarse woody debris had a strong positive effect on N, CO_N and H'.…”

Carabid beetle assemblages in three environments in the Araucaria humid forest of southern Brazil

“…A change in species composition is a recurring observation (Uehara-Prado et al 2009;Latty et al 2006), since the group has a high sensibility to environmental changes in general (Scott & Anderson 2003), including canopy species (Lucky et al 2002;Erwin et al 2005). It is exactly this characteristic of carabids that render them good bioindicators, and it shows up in our subtropical Neotropical data.…”

“…It is known that few species tend to numerically dominate carabid assemblages. For example, Latty et al (2006) reported 61% of all individuals belonging to four common species in logged areas. Silva et al (2008) also found a single dominant species of carabid in a survey in areas under silviculture with for exotic Eucalyptus.…”

Arthropod Diversity and Functional Importance in Old-Growth Forests of North America

“…Younger forests with less accumulated litter are subject to greater variation in forest floor temperature and moisture [52]. Arthropods associated with the forest floor are instrumental in the inoculation of litter with microorganisms that are responsible for litter decomposition and release of nutrients that become available for new plant growth and help sustain primary production [4,15,36,52]. Most data for arthropods associated with old-growth forests are from the forest floor, given the relative accessibility and simple collecting equipment (e.g., cloth bags, pitfall traps, and soil coring tools) necessary to sample this habitat.…”

“…Carabid beetles have been a focus of several studies because of relatively good taxonomic resolution. Latty et al [4] found that forest floor arthropod assemblages in old-growth were distinct from assemblages in younger, managed forests and identified five carabid species (including Carabus sylvosus, Agonum gratiosum, Myas cyanescens and Platynus decentis) that were significant indicators of old-growth forests in northern Wisconsin and Upper Michigan, compared to two significant indicators of younger, managed forests (Harpalus fulvilabris and Pterostichus coracinus) (Figure 4). Willett [63] found that the diversity and abundance of spiders also was greater in stands of old-growth redwood, Sequoia sempervirens, compared to 100 year old or younger stands.…”
