Habitat Heterogeneity Affects Plant and Arthropod Species Diversity and Turnover in Traditional Cornfields
The expansion of the agricultural frontier by the clearing of remnant forests has led to human-dominated landscape mosaics. Previous studies have evaluated the effect of these landscape mosaics on arthropod diversity at local spatial scales in temperate and tropical regions, but little is known about fragmentation effects in crop systems, such as the complex tropical traditional crop systems th...
متن کاملHabitat heterogeneity overrides the species–area relationship
Species–area relationships are amongst the most studied ecological phenomena (Connor & McCoy, 1979; Rosenzweig, 1995; Whittaker, 1998; Báldi & McCollin, 2003; HornerDevine et al., 2004; Martin & Goldenfeld, 2006). They encapsulate the general pattern that larger islands/areas contain more species than smaller ones (e.g. MacArthur & Wilson, 1967). Although there is strong evidence for the genera...
متن کاملAnimal species diversity driven by habitat heterogeneity/diversity: the importance of keystone structures
The ‘habitat heterogeneity hypothesis’ is one of the cornerstones of ecology (e.g. Simpson, 1949; MacArthur & Wilson, 1967; Lack, 1969). It assumes that structurally complex habitats may provide more niches and diverse ways of exploiting the environmental resources and thus increase species diversity (Bazzaz, 1975). In most habitats, plant communities determine the physical structure of the env...
متن کاملIsland species richness increases with habitat diversity.
Species richness is commonly thought to increase with habitat diversity. However, a recent theoretical model aiming to unify niche and island biogeography theories predicted a hump-shaped relationship between richness and habitat diversity. Given the contradiction between model results and previous knowledge, we examine whether the relationship between species richness and habitat diversity is ...
متن کاملSpecies Diversity and Larval Habitat Characteristics of Mosquitoes (Diptera: Culicidae) in Golestan Province, 2016
Background & Objectives: Mosquitoes (Diptera: Culicidae) are medically considered as one of the most important species of insects in terms of disease transmission to human beings; hence, they can be vectors of remarkable diseases such as malaria, West Nile, dengue fever, yellow fever, and filariasis. This study aimed to determine the species diversity and larval habitat characteristics of mosqu...
