“…Apart from land use and farm management methods or farming practices (Weibull and Östman 2003), vegetation structure, quality of the matrix surrounding an agricultural habitat (Binzenhöfer et al 2008;Summerville et al 2008), diversity and types of habitats (Dessuy and de Morris 2007;Ngai et al 2008;Kumar et al 2009), landscape heterogeneity and habitat connectivity (Davis et al 2007) are important factors determining occurrence, movements, population dynamics, seasonality, persistence and longterm survival of Lepidoptera faunal communities in the agricultural landscapes (Dennis 2003;Greza et al 2004;Chay-Hernández et al 2006;Kivinen et al 2008;Öckinger and Smith 2008;Pickens and Root 2008;Stasek et al 2008;Dover and Settele 2009;Brückmann et al 2010). Generally, agricultural matrices that are more resembling a nearby forest patch maintain higher butterfly diversity than matrices with lesser shade cover (Summerville et al 2001;Kitahara and Watanabe 2003;Weibull and Östman 2003;Boriani et al 2005;Aviron et al 2007;Ohwaki et al 2007Ohwaki et al , 2008Barlow et al 2008;Bergman et al 2008;van Halder et al 2008;Marín et al 2009). …”

A study was conducted in 26 sites on agricultural landscapes in Central Uganda to collect baseline information about important drivers of butterfly richness and abundance. Data were collected for 1 year (2006) using line transects walk-and-counts, fruit-bait traps and handnets sampling methods. A total of 57,439 individuals belonging to 331 species were collected. Totals of 127, 131 and 299 species were recorded in transect counts, banana-bait and handnets, respectively. Of the 57,439 individuals registered, 75%, 19% and 6% were recorded in transect counts, handnet and banana-bait trap, respectively. Butterfly abundance and species richness were significantly (p < 0.05) affected by climatic factors (rainfall, temperature) in previous years (2004 and 2005) and richness and abundance of wild nectaring plants. Butterfly species richness (not the abundance) decreased with land-use intensity (p < 0.05) and was positively related to the cover of semi-natural habitats. Both butterfly species richness and abundance declined sharply with forest distance. Nearby forest remnants and high cover of semi-natural habitats are thus important for conservation of butterflies in coffee-banana agroforestry systems and farmers should be encouraged to protect such resources.

Ecologists have long been intrigued by the factors that control the pattern of biodiversity, i.e., the distribution and abundance of species. Previous studies have demonstrated that coexisting species partition their resources and/or that the compositional similarity between communities is determined by environmental factors, lending support to the niche-assembly model. However, no attempt has been made to test whether the relative amount of resources that reflects relative niche space controls relative species abundance in communities. Here, we demonstrate that the relative abundance of butterfly species in island communities is significantly related to the relative biomasses of their host plants but not to the geographic distance between communities. In the studied communities, the biomass of particular host plant species positively affected the abundance of the butterfly species that used them, and consequently, influenced the relative abundance of the butterfly communities. This indicated that the niche space of butterflies (i.e., the amount of resources) strongly influences butterfly biodiversity patterns. We present this field evidence of the niche-apportionment model that propose that the relative amount of niche space explains the pattern of the relative abundance of the species in communities. neutral theory ͉ niche theory ͉ relative species abundance B iodiversity is often considered to be synonymous with species richness and relative species abundance (1). For more than half a century, ecologists have paid attention to the factors that determine the relative species abundance in ecological communities; i.e., the commonness and rarity of species (2). Host plants and their herbivore communities are good systems for examining how the diversity of herbivores is influenced by their resources; indeed, insect ecologists have focused considerable attention on the question of how host plant communities affect the species richness and composition of insects. Although a recent review (3) pointed out that little progress on this subject has been made since the 1980s, a number of important studies have demonstrated that a large number of plant species is frequently correlated with a large number of insect species (4-6). Experimental studies have also demonstrated a positive relationship between the diversity of plant species and the diversity of consumers (7-9). The abundance of resources also represents an important factor in the structuring of insect communities (10). A number of studies have demonstrated that resource abundance explains the variation in the abundance and species richness of herbivorous insects (11)(12)(13)(14). However, these studies on host plant and herbivore communities have treated species richness and species composition as components of the diversity, and no studies have examined the relative abundance patterns of both host plants and herbivores.On the other hand, recent theoretical arguments have focused on whether the neutral or niche theory better explains the patterns of relative spec...

“…The other reason is that these two sections include forest edge. It is well known that species richness of butterflies is highest at the forest edge (Hill et al 1992;Ishii et al 1995;Ishii 1996;Kitahara and Watanabe 2003). However, since forest edge is a border between two different vegetation types, forest edge contains diverse vegetations as such.…”

“…Several butterfly studies in Japan have stressed on the importance of forest edge for conservation because of high butterfly diversity (Ishii 1996) and presence of endangered species (Kitahara and Watanabe 2003). In the case of Kitahara and Watanabe (2003), these endangered species depend on semi-natural grasslands along the forest edge. However, regrettably, semi-natural grasslands have been already lost from most satoyama areas in Japan (Tabata 1997;Inoue 2005).…”

Butterfly assemblages in a traditional agricultural landscape: importance of secondary forests for conserving diversity, life history specialists and endemics

2006

Satoyama, the traditional agricultural landscape in Japan, has drawn much attention from the viewpoint of biodiversity conservation. It is composed of diverse vegetation types, including secondary forests, paddy fields and cultivated fields in a narrow area (ca. 1 km 2 ). To clarify the characteristics of butterfly assemblage and the relative contribution of each vegetation type to butterfly diversity and endemism in satoyama, we conducted a line-transect survey along a 1.1-km route with five sections (two forest interior, one interior-edge, one edgeopenland and one openland). Life history features (voltinism, host plant range and host plant type) and endemism of butterflies were discussed in relation to their abundance and vegetation association. Fifty-one species and 856 individuals were recorded. Species richness was highest in the two sections with edges, 32 and 36 species, respectively. Analysis of vegetation association of each butterfly species showed that 16 species were forest interior species, 24 forest edge species and 11 openland species, indicating that vegetation diversity enhanced butterfly diversity. However, the point is that forest interior and edge species contained many specialists sensitive to human impact (univoltine and/or oligophagous species) and many species within temperate East Asia including all endemic species. In contrast, most openland species were generalists (multivoltine and/or polyphagous species) feeding on herbs/grasses with the widest geographic range. Since secondary forests kept Ó Springer Science+Business Media B.V. 2006 more butterfly diversity and specialists than openlands, and had all endemic species, they must be maintained without over fragmentation in order to avoid loss of specialists and endemics in satoyama.
