Community Composition of Longhorned Beetles (Coleoptera: Cerambycidae) in the Canopy and Understorey of Sugar Maple and White Pine Stands in South-Central Ontario

The vertical stratification of lepidopteran and coleopteran communities in a cool-temperate deciduous forest in Japan was examined to evaluate the hypothesis of an expected uniform distribution of mobile flying insects between the canopy and understory of temperate forests. Lepidopteran and coleopteran insects were trapped using light traps at three sites in each of the canopy and understory for three consecutive nights each month from April to October 2001. For Lepidoptera, species richness, abundance, and family richness were significantly higher in the understory than in the canopy. For Coleoptera, only abundance was larger in the canopy relative to the understory; species and family richness did not differ between the strata. The beta diversity of the lepidopteran community was larger between the strata than among sites, but the coleopteran community showed an inverse pattern. These results imply the presence of vertical stratification within the lepidopteran community, but not within the coleopteran community, in the temperate forest. The understory contributes more than the canopy to lepidopteran diversity in the temperate forest, although this stratification may be relatively weak because, in contrast to the situation in tropical forests, the canopy and understory assemblages share many species.

“…Research in the southeastern United States of America depicts a higher diversity of Coleoptera in the understorey than in the canopy, and distinct stratification of beetles in these two strata (Ulyshen and Hanula 2007). Vance et al (2003) found differences between the Cerambycidae fauna in the canopy and that in the understorey. North-temperate forests are heterogeneous environments, and the effects of vertical stratification do not operate independently of other influences, including the effects of small forest gaps.…”

Activity of flying beetles (Coleoptera) at two heights in canopy gaps and intact forests in a hardwood forest in Quebec

Abstract-We studied the effects of forest height and forest gap on assemblages of flying beetles in an American beech (Fagus grandifolia Ehrh. (Fagaceae) -sugar maple (Acer saccharum Marsh. (Aceraceae)) forest in Quebec. From June until August of 2005, beetles were collected in Lindgren funnel traps placed in the canopy (20-25 m height) and upper understorey (3-5 m height) in proximity to five forest gaps (15-30 m in diameter) (at the edge of the forest opening or within the closed-canopy forest). We collected 1852 beetles representing 38 families and 172 species. Based on rarefaction curves, species richness was significantly higher in the canopy than in the upper understorey. Nonmetric multidimensional scaling ordination revealed a change in species composition in relation to vertical stratification but not to the forest gaps. Our findings confirmed the importance of the vertical forest gradient to overall diversity of forest coleopterans.Résumé-Nous avons étudié les effets de l'ouverture et de la structure verticale du couvert forestier sur la structure des assemblages de Coléoptères dans une hêtraie (Fagus grandifolia Ehrh., Fagaceae) -érable à sucre (Acer saccharum Marsh., Aceraceae) au Québec. Les Coléoptères ont été échantillonnés à l'aide de pièges Lindgren positionnés dans la canopée (20-25 m de hauteur) et en sous-couvert (5 m de hauteur) à proximité de 5 trouées de 15-30 m de diamètre (en bordure de la trouée versus forêt d'intérieur) et ce du début juin à la fin d'aoû t 2005; 1852 individus appartenant à 172 espèces et 41 familles ont été collectés. La richesse spécifique, estimée à l'aide de courbes de raréfaction, s'est montrée plus élevée dans la canopée. Un cadrage non -métrique multidimensionel a démontré un changement au niveau de la composition spécifique en lien avec la position verticale des pièges, mais non au niveau de la proximité aux trouées. Notre étude confirme que la diversité structurelle fournie par le gradient vertical en forêt contribue de façon importante à la diversité des Coléoptères en milieu forestier.

“…These results are supported by Peris-Felipo et al (2011), who showed that the diversity of longhorn beetles in pine forest was higher than in quercus forest, mixed forest, and shrub vegetation. Vance et al (2003) also reported that pine stands are potentially important for maintaining diversity of longhorn beetles. In our research, the location of the pine forest was close to natural forest and various species of understorey plant could be found.…”

Gunung Walat Educational Forest is located at an altitude of 500-700 m asl and has a variety of forest types. This research investigated the diversity and abundance of longhorn beetles found in several types of plantation forest. The beetles were collected using Artocarpus traps in September and October 2014. Sixteen species of longhorn beetle were found; these belonged to 7 tribes and 12 genera. The highest diversity and evenness of longhorn beetles were found in the natural forest (H=1.80, E=0.75) and the lowest of both measures in the Agathis forest (H=0.556, E=0.232). The highest similarity index (0.75) was found between the natural forest and the pine forest. Five of the species found, i.e. Sybra binotata, Sybra fuscotriangularis, Ropica strandi, Acalolepta rusticatrix, and Pterolophia melanura were highly abundant. Two of these, R. strandi and S. fuscotriangularis, as well as 4 other species found, Cleptometopus montanus, Myagrus javanicus, Notomulciber notatus, and Exocentrus artocarpi, are only found in Java. Finding Ropica marmorata was the first such record of this species on the island of Java.
