“…of different design, some taxonomic groups tend to be preferentially captured. Basset (1988) used a composite interception trap which comprised a Malaise trap and the lower section of the omnidirectional window trap (Wilkening et al 1981) used in this study. The two most strongly represented groups in that study were Diptera and Coleoptera, representing 48 and 10% of the Malaise catch and 14 and 54% of the window catch, respectively.…”

“…McWilliam & Death-Rainforest arboreal arthropod communities 159 here was modified from that of Wilkening et al (1981). It is intended to be non-attractive, to capture arthropods flying from any direction, and to collect both the animals which fall and those which climb following impact with either of two clear PVC panes.…”

“…Gaining access to the canopy for personnel and sampling equipment has taken on a wide variety of forms, including rope techniques (Perry 1978;Perry & Williams 1981), aerial walkways (Mitchell 1986), inflatable canopy rafts (Halle 1990;, helium balloons (Fukuyama et al 1994), and most recently construction cranes (Parker et al 1992;Morell 1994). Collecting data about arboreal arthropod communities has involved studying faunal lists Kennedy & Southwood 1984), the use of insecticide fogs and sprays (e.g., Southwood et al 1982;Stork 1987a;Morse et al 1988;Basset 1991), branch clipping (Majer & Recher 1988), light trapping (Sutton 1983), and flight interception trapping (Wilkening et al 1981;Basset 1988;Didham 1992).…”

Arboreal arthropod communities from three reserves of podocarp-hardwood rainforest in the North Island, New Zealand, were sampled continuously between June 1995 and May 1996 using omnidirectional window traps. Diptera made up 34% of the total number of arthropods captured, whereas Coleoptera contributed 12% and Araneae 11% to the total catch. The relative abundance and species richness of Diptera peaked in spring, Coleoptera in summer, and Araneae in autumn. Multivariate analysis of overall community structure suggests that season is the dominant determinant of community structure in the arboreal arthropod communities of these forest patches, whereas site, and to a lesser extent tree species, have minor effects. Given that 863 morphospecies were collected, the conservation value of small forest patches for forest-dwelling arthropods in New Zealand should not be underestimated.

“…On each site, we installed an equal number of sampling devices, comprising (1) three funnel pitfall traps, each consisting of a collecting jar inside a plastic sleeve, an 11 cm diameter funnel and a transparent plastic roof 20 cm in diameter (Southwood 1978), (2) one Malaise trap (after Townes 1972) with a 1.5 m 2 black vertical mesh panel, (3) one flight intercept trap intercepting insects flying between 1.0 and 1.5 m above the ground, consisting of two crossed black vertical mesh panels, each measuring 0.25 m 2 (0.5 · 0.5 m), and top and bottom funnels 50 cm in diameter (Wilkening et al 1981), and (4) one pyramid-shaped emergence trap (ground photoeclector) covering an area of 0.75 m 2 (% 0.86 · 0.86 m), equipped with a collecting jar on the top and one pitfall trap (Mu¨hlenberg 1993). The traps were spaced out along 30 m north-south transects.…”

Arthropod Diversity in Lama Forest Reserve (South Benin), a Mosaic of Natural, Degraded and Plantation Forests

et al. 2006

Arthropod assemblages were examined in Lama forest reserve, a protected area situated in the Dahomey gap, southern Benin, composed of plantations, degraded forest and remnants of natural forest. The objectives were to compare assemblages in relation to forest type and use, to elucidate the value of forest plantations for biodiversity conservation and to identify indicator species for specific forest habitats. Arthropods were collected over an 11-month period, using standardized sets of traps (pitfall, emergence, Malaise and flight intercept traps). Nine different habitats were studied, including natural and degraded forest, forest plantations (Tectona grandis and Senna siamea) of different age, and isolated forest fragments. Our analysis focused on detritivorous and xylophagous arthropods but also included ground beetles and heteropterans, totalling 393 species. We found no differences in species richness among natural and degraded forest habitats in the centre of the reserve (Noyau central). Outside of the Noyau central, species richness was highest in old teak plantations and isolated forest fragments and lowest in young teak and fuelwood plantations. Detrended correspondence analysis (DCA) separated three main groups: (1) natural forest, (2) degraded forest and young plantations, and (3) old plantations and isolated forest fragments. Multiple regression of DCA scores of the first two axes on environmental variables identified one natural and three disturbance-related predictors of arthropod assemblages in Lama forest: soil type (texture), canopy height, naturalness (proportion of Guineo-Congolian plant species) and understorey vegetation cover. We identified 15 indicator species for six different forest habitats. The highest numbers were found in abandoned settlements and old teak plantations. b-diversity was similar among the three DCA ordination groups (degraded forest excluded). Values for b-diversity were relatively high, suggesting that all major forest habitats contribute significantly to regional species pools and should therefore be protected. To enhance arthropod diversity, we propose that management practices in Lama forest should aim to encourage the development of species-rich understorey vegetation of the Guineo-Congolian phytogeographical region.

Abstract. Arthropod assemblages were examined in Lama forest reserve, a protected area situated in the Dahomey gap, southern Benin, composed of plantations, degraded forest and remnants of natural forest. The objectives were to compare assemblages in relation to forest type and use, to elucidate the value of forest plantations for biodiversity conservation and to identify indicator species for specific forest habitats. Arthropods were collected over an 11-month period, using standardized sets of traps (pitfall, emergence, Malaise and flight intercept traps). Nine different habitats were studied, including natural and degraded forest, forest plantations (Tectona grandis and Senna siamea) of different age, and isolated forest fragments. Our analysis focused on detritivorous and xylophagous arthropods but also included ground beetles and heteropterans, totalling 393 species. We found no differences in species richness among natural and degraded forest habitats in the centre of the reserve (Noyau central). Outside of the Noyau central, species richness was highest in old teak plantations and isolated forest fragments and lowest in young teak and fuelwood plantations. Detrended correspondence analysis (DCA) separated three main groups: (1) natural forest, (2) degraded forest and young plantations, and (3) old plantations and isolated forest fragments. Multiple regression of DCA scores of the first two axes on environmental variables identified one natural and three disturbance-related predictors of arthropod assemblages in Lama forest: soil type (texture), canopy height, naturalness (proportion of Guineo-Congolian plant species) and understorey vegetation cover. We identified 15 indicator species for six different forest habitats. The highest numbers were found in abandoned settlements and old teak plantations. b-diversity was similar among the three DCA ordination groups (degraded forest excluded).

To enhance arthropod diversity, we propose that management practices in Lama forest should aim to encourage the development of species-rich understorey vegetation of the Guineo-Congolian phytogeographical region.
