Diversity Of Water Bugs In Gujranwala District, Punjab, Pakistan, Muhammad Shahbaz Chattha, Abu Ul Hassan Faiz, Arshad Javid, Irfan Baboo, Inayat Ullah Malik
Journal of Bioresource Management
Water bugs fall under the order Hemiptera, suborder Heteroptera, which is further divided into two types, i.e., semi-aquatic (Gerromorpha) and true water bugs (Nepomorpha). They play a vital role as biological control agents and also a source of food for fishes, birds and other aquatic organisms. The present work was carried out to ascertain aquatic Hemiptera in different lentic and lotic water bodies of various sizes in Gujranwala district, Pakistan. A total of 10 species belonging to five families were identified. Species include Nepa ruber Linnaeus, Laccotrephes elongatus Montandon, Ranatra filiformis Fabricius (Nepidae), Corixa substriata Uhler, Micronecta proba …
Effects Of Wave Action On The Structure Of Fish Assemblages Across An Exposure Gradient, Lauren Liddon
Effects Of Wave Action On The Structure Of Fish Assemblages Across An Exposure Gradient, Lauren Liddon
Master's Theses
Disturbance affects the function and diversity of ecosystems. Increased wave exposure to salt marsh can disturb sediments and cause a loss of habitat. The purpose of this study was to explore the effects of increased wave exposure on diversity, abundance, and functional ecology of estuarine fishes. If increased wave exposure is acting as a disturbance to these habitats, ecological theory (Intermediate Disturbance Hypothesis) predicts that diversity will peak at intermediate frequencies and intensities of disturbance. Fish were sampled from 10 sites monthly for 6 years. The sites were assigned to different exposure categories (Open, Intermediate, and Sheltered) using an exposure …
The Bee Fauna Of The Horse Mountain And Grouse Mountain Region, Humboldt County, California, Carrie Lopez
The Bee Fauna Of The Horse Mountain And Grouse Mountain Region, Humboldt County, California, Carrie Lopez
Cal Poly Humboldt theses and projects
Recent concerns about the ecological well-being of bee communities in California and elsewhere have increased the need for monitoring programs and studies that evaluate the impact of habitat loss and alteration on bee diversity and abundance. Such studies depend critically on the expertise of people trained in taxonomy, but their numbers have declined in recent years. My primary goal was to gain a comprehensive first-hand experience with bee identification by documenting the fauna of a previously unstudied area in the mountains of northwestern California and by writing an identification key, intended for dedicated non-specialists, to the area’s 35 species of …

Species Diversity And Community Structure Of Zooplankton In Threedifferent Types Of Water Body Within The Sakarya River Basin, Turkey, Pinar Gürbüzer, Özge Buyurgan, Çağri Tekatli, Ahmet Altindağ
Turkish Journal of Zoology
The aim of this study was to identify differences between different types of water body within the same river basin by comparing the composition of the zooplankton community. The study was conducted in three types of water body in the Sakarya Basin in northwestern Turkey: an alluvial barrier lake (Lake Poyrazlar), a pond (Sorgun Pond), and a reservoir (Çubuk II Reservoir). The spatiotemporal changes of these three types of aquatic habitats were investigated in terms of the zooplankton organisms by examining their diversity, evenness, and differences in the abundance of species. A total of 81 species were identified. Thirty-eight species …

Turkish Journal of Zoology
Zooplankton composition and abundance were investigated seasonally at 6 sites in Lake Karaboğaz in relation to some physicochemical conditions. A total of 63 taxa were identified, among them 51 species of rotifers, 8 cladocerans, and 4 copepods. Rotifera represented the predominant component (79% of the total community), followed by nauplii, cladocerans, and copepods (15%, 5%, and 1%, respectively). The average total zooplankton abundance ranged from 9603 to 22,968 ind/m^3. The maximum and the minimum densities were measured in June and August of 2009, respectively. Of the identified zooplankton, 39 taxa were species with a low frequency in the lake. Among …
