Tropical forests are predicted to harbor most of the insect diversity on earth, but few studies have been conducted to characterize insect communities in tropical forests. One major limitation is the lack of consensus on methods for insect collection. Deciding which insect trap to use is an important consideration for ecologists and entomologists, yet to date few study has presented a quantitative comparison of the results generated by standardized methods in tropical insect communities. Here, we investigate the relative performance of two flight interception traps, the windowpane trap, and the more widely used malaise trap, across a broad gradient of lowland forest types in French Guiana. The windowpane trap consistently collected significantly more Coleoptera and Blattaria than the malaise trap, which proved most effective for Diptera, Hymenoptera, and Hemiptera. Orthoptera and Lepidoptera were not well represented using either trap, suggesting the need for additional methods such as bait traps and light traps. Our results of contrasting trap performance among insect orders underscore the need for complementary trapping strategies using multiple methods for community surveys in tropical forests.

“…A large number of windowpane trap types have been developed based on this model (Springate and Basset 1996, Hill and Cermak 1997, Carrel 2002, Fielding 2003, Fayt et al 2006, Bouget et al 2008, Missa et al 2009, Grimbacher and Stork 2009), but to date no standardized method has been widely accepted.…”

“…However, our results did not support this, perhaps because our shrub-layer traps were located above the ground vegetation and we did not sample the fauna associated with the lower herbaceous layer. If we had sampled closer to the ground, understorey beetle diversity would have been higher (Hill and Cermak 1997), a finding reported by Ulyshen and Hanula (2007).…”

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.

“…This gave a trapping effort of approximately 240 trap‐days for each bait type. Additionally, two flight intercept traps (FITs), an effective method of capturing actively foraging dung beetles (Hill & Cermak, 1997), were set up locally and run for approximately 2 weeks, to collect diet specialists (e.g. feeding on decaying fungi and fruit, or small‐sized dung pellets).…”

Aim Niche partitioning within species assemblages is thought to influence species packing and/or total niche space occupied. The evolution of dung beetles (Scarabaeinae) is likely to have been strongly influenced by inter-specific competition, leading to niche partitioning. We consider whether local-scale processes leave a signature in regional patterns of functional diversity in dung beetle assemblages, and investigate the correlation between total exploited ecomorphological space and density of species packing with increased species richness. We test whether ecomorphological space occupied by local assemblages reflects that of their regional species pool, and the extent to which ecomorphological space is convergent or divergent within functional groups across regional pools.Location Neotropics, Africa, Australia and Madagascar.Methods Dung beetle assemblages were collected in a standardized manner from four biogeographic regions. Ecomorphological similarity among the assemblages was assessed by multivariate analysis of 19 linear measurements for 300 species and three functional nesting types (roller, tunneller or dweller), firstly on a local level within the Neotropics and Afrotropics, and then between the regional species pools.Results Key body measurements, in particular the hind tibia, separated rollers and tunnellers into largely non-overlapping entities along the first three axes of the shape analysis. Three Neotropical assemblages, which vary widely in species numbers, each harboured a similar amount of morphometric variation, resulting in increasingly dense species packing with greater species richness. Similar findings were obtained in two South African assemblages. Assemblages in the four biogeographic regions showed largely similar distributions of ecomorphological variation, including the separation of rollers and tunnellers, despite their distant phylogenetic relationships. Ecomorphological similarity among regions was particularly high in tunnellers, whilst the rollers exhibited greater regional differentiation.Main conclusions Local assemblages evidently represent the full diversity of functional groups available in the regional pool, even in species-poor assemblages. There is a strong trend towards convergence in morphology separating tunnellers and rollers in phylogenetically independent lineages. The ecomorphological similarity of regional assemblages suggests that morphological convergence is the result of common selective forces active within the assemblages themselves. This lends support to the widely hypothesized effect of inter-specific interactions and niche partitioning in determining assemblage composition and lineage evolution in the Scarabaeinae.
