Replicated hybrid zones of Xiphophorus swordtails along an elevational gradient.
Natural hybrid zones provide opportunities to study a range of evolutionary phenomena from speciation to the genetic basis of fitness-related traits. We show that widespread hybridization has occurred between two neo-tropical stream fishes with partial reproductive isolation. Phylogenetic analyses of mitochondrial sequence data showed that the swordtail fish Xiphophorus birchmanni is monophylet...
متن کاملA Complex Metacommunity Structure for Gastropods Along an Elevational Gradient
The metacommunity framework integrates species-specific responses to environmental gradients to detect emergent patterns of mesoscale organization. Abiotic characteristics (temperature, precipitation) and associated vegetation types change with elevation in a predictable fashion, providing opportunities to decouple effects of environmental gradients per se from those of biogeographical or histo...
متن کاملPatterns of distribution and plant diversity in along elevational gradient (Case study: Moghan-Sabalan rangelands)
The study of plant communities is the best way to learn about vegetation structure and distribution as well as various interactions among the plants in an ecosystem. Elevation factor plays a vital role in plant distribution that ultimately leads to specific phytogeographic regions. This study evaluated the changes in species composition, density, frequency, canopy cover and palatability of spec...
متن کاملVariation in herbivory by Yponomeuta mahalebella on its only host plant Prunus mahaleb along an elevational gradient
1. The effect of natural variation in abiotic conditions on the herbivory interaction between Prunur mahaleb (Rosaceae) and its monophagous folivore, larvae of Yponomeuta mahalebella (Lepidoptera, Yponomeutidae), was analysed for 2 consecutive years along an elevational gradient in Sierra de Cazorla, south-east Spain. 2. There was a negative correlation between site elevation and mean populatio...
متن کاملLeaf litter decomposition and microarthropod abundance along an altitudinal gradient
Mass loss rates of three types of leaf litter were measured along an altitudinal gradient at the Coweeta Hydrologic Laboratory, Macon County, North Carolina. Litterbags containing air dried litter from Quercus prinus L., Liriodendron tulipifera L., and Rhododendron maximum L. were placed in five plots along the gradient and sampled monthly. Microarthropods were extracted and sorted, and litter ...
