“…In all, eight samples were collected per site. We collected over a full lunar cycle to control for the effects of the moon on trap effectiveness ( Nag & Nath 1991), and we arbitrarily reassigned traps and batteries to sites each night to remove any bias of lamp brightness or battery strength.…”

Studies of fragmented landscapes, especially in the tropics, have traditionally focused on the native fragments themselves, ignoring species distributions in surrounding agricultural or other human-dominated areas. We sampled moth species richness within a 227-ha forest fragment and in four surrounding agricultural habitats (coffee, shade coffee, pasture, and mixed farms) in southern Costa Rica. We found no significant difference in moth species richness or abundance among agricultural habitats, but agricultural sites within 1 km of the forest fragment had significantly higher richness and abundance than sites farther than 3.5 km from the fragment. In addition, species composition differed significantly between distance classes (but not among agricultural habitats), with near sites more similar to forest than far sites. These results suggest that (1) different agricultural production regimes in this region may offer similar habitat elements and thus may not differ substantially in their capacities to support native moth populations and (2) that the majority of moths may utilize both native and agricultural habitats and move frequently between them, forming "halos" of relatively high species richness and abundance around forest fragments. Correlations between species richness and the amount of nearby forest cover, measured over circles of various radii around the sites, suggest that halos extend approximately 1.0-1.4 km from the forest edge. The extent of these halos likely differs among taxa and may influence their ability to survive in fragmented landscapes.

“…The following authors explain the lower catches recorded when there is a Full Moon in terms of a shorter collecting distance: Bowden & Curch (1973), Vaishampayan & Shrivastava (1978), Vaishampayan & Verma (1982), Nag & Nath (1991). Shrivastava et al (1987) also suggest that the lower catches of light traps when there is a Full Moon may be due to the stronger and brighter light of the Moon and a smaller collecting area, which are clearly physical phenomena.…”

Abstract. In this study we examine the relationship between the Lunar Phases and the efficiency of light traps in catching winter moth (Operophthera brumata Linnaeus, 1758). Our calculations are based on data collected by the Hungarian Forestry Light Trap Network at four sites from 1961 to 2008. We also tried to estimate the influence of polarized moonlight and collecting distance, which also depends on moonlight. Our investigations revealed that the catches were the greatest in the First and the Last Quarters, and the lowest at Full Moon. The reason for this is that the proportion of polarized moonlight in the different lunar quarters varies, with the catches highest when the proportion is greatest. Collecting distance has only a minor role.

“…Therefore, we predicted that invertebrate would be more abundant in the farmland than in the interior of ASF. Many nocturnal invertebrates, especially the different species of beetles and moths are easily attracted by artificial light at night [19] . Light traps are widely used to sample different invertebrate species which are active at night [20] .…”

The primary food of insectivorous bats is invertebrates. This study investigated invertebrate abundance in ASF and adjacent farmland, in order to understand its availability to foraging insectivorous bats found in both study sites. Invertebrate were sampled with solar powered lights, which attracted air-borne invertebrates to a suspended white cloth sheet, for four hours each night in 12 different stations each in ASF and farmland. In total 6,557 individuals of invertebrates were captured: 52% in the farmland and 48% in ASF. The order Hymenoptera (ants, bees, wasps and sawflies) was the most abundant (38.1%), followed by Coleoptera (beetles (28.1%). The Shannon-Weiner index of diversity was higher in ASF (1.72 ± 0.1) than in the farmland (1.41 ± 0.1). The mean number of invertebrates captured each night in the farmland was (260.5 ± 52.9, N=12), and in ASF (200.3 ± 36.4, N=12), but there was no significant difference between the medians of captured invertebrates in both study sites (Mann-Whitney U-Test, U=61: P>0.544). In conclusion, the farmland and forest had similar invertebrate abundance. This study, highlight the importance of agricultural landscapes, which have been ignored in many biodiversity surveys, in providing invertebrate prey items to insectivorous bats especially in the study area.
