Wetlands are significant habitats for avian populations, and knowledge of the diversity and other ecological aspects of waterbirds contribute a lot to the management of the ecosystem. The present study was conducted based on comparative studies on the diversity and relative abundance of waterbird species in the three wetlands of southwest Ethiopia. The point count method was utilized in this study. For the data analysis, the Shannon-Weaver diversity index, independent sample t-test, and similarity index were employed. A total of 46 bird species under 11 orders and 30 families were identified. The species diversity and relative abundance were higher in all of the three wetlands during the wet season. The Loga wetland had the highest diversity (H’ = 3.089), whereas the lowest diversity (H’ = 2.643) was recorded in the wetland of Hurri. During the dry season, the highest and the lowest diversity were also recorded in the Loga wetland (H’ = 2.738) and the Hurri habitat (H’ = 2.283), respectively. There is no statistically significant difference between seasons in the species diversity of waterbirds (p > 0.05). Since the existence of waterbirds is based on a wetland ecosystem; human activities very near to the wetland should be controlled for their sustainable conservation.

“…We chose to work with reptiles and amphibians (ectotherms) and the mosquitoes that feed upon them. Ectotherms are abundant in most ecosystems (Pough 1980, Gibbons et al 2006, and can be surveyed visually (Manley et al 2006) as well as auditorily (USGS 2008 North American Amphibian Monitoring Program). Mosquitoes are quite mobile and thus able to move in response to their environment (in contrast to wingless parasites such as ticks which have limited mobility).…”

“…Standard herpetological survey methods were used, including visual searches (15-min examination within 30-m radius of each station [Manley et al 2006]) and auditory surveys (number of vocalizing male frogs within 50-m of each station, estimated when .10 males were vocalizing synchronously) (Weir and Mossman 2005). Each of the 37 stations was surveyed on eight occasions (four daytime and four nighttime visits) from mid-May through early September.…”

Hosts or habitats: What drives the spatial distribution of mosquitoes?

et al. 2013

Abstract. Understanding the factors that influence the distribution of vectors is critical to assess the risk of disease transmission across landscapes. For mosquitoes, existing spatial models use only habitat elements (hydrologic and floristic) to predict the distribution of disease vectors within the landscape, ignoring the potential importance of the distribution of hosts. We tested the hypothesis that the distribution of hosts would better explain the spatial distribution of mosquitoes than habitat variables using Information Theory and Poisson Regression. We analyzed the abundance of ectotherm-biting mosquitoes and their hosts from 37 points over a 28-km 2 area in Tuskegee National Forest, Alabama, USA. We compared models built using information regarding habitat, hosts, or both for their ability to explain the abundance of Culex peccator and Culex territans, two mosquito species that specialize on reptiles and amphibians. Models built using both host and habitat information were the best models for both species, suggesting that information regarding the distribution of mosquito hosts greatly improves models of mosquito distributions. Moreover, when differences in habitat makeup among stations were accounted for, mosquitoes were found to be significantly more abundant at locations with greater host abundance. Since most mosquitoes feed on only a limited range of hosts and successful blood feeding is one of the most crucial bottlenecks in the life cycle of mosquitoes, it follows that mosquitoes would aggregate in areas of greatest host density. Habitat influences the availability of suitable larval development sites, and to some extent, distribution of hosts. Our analysis, however, shows that within the landscape the distribution of host animals is a crucial factor in determining the spatial distribution of vectors. This has clear and important implications for determining which areas are at a greater risk for zoonotic arboviruses and is a potentially transformative paradigm for understanding the factors that influence the spatial distribution of disease vectors.
