Investigating Mechanisms of Co-Occurrence Between Two Similar Specis of Predaceous Diving Beetles (<i>Coleoptera: Dytiscidae</i>) in Temporary Aquatic Habitats
… species of the family interact in isolated, aquatic habitats, and are ubiquitous throughout landscapes. Two morphologically similar species, laccophilus fasciatus rufus and Laccophilus proximus, co-occur in numerous habitats in South Mississippi, but are hypothesized to have strong …

Effects of Supraseasonal Drought on Karst Aquatic Communities of the Edwards Plateau
… of a supraseasonal drought (2022 – 2024) on aquatic habitats, mussel assemblage, and fish assemblage within headwater (N = 6 sites), mainstem (N = 10 sites), and tributary (N = 4 sites) reaches of the upper Guadalupe River. At the start of an exceptional drought in 2022 and through 2024, …

Mechanisms Controlling Hatching of Winter Eggs of the Flatworm Mesostoma Ehrenbergii
… and have been recorded from a variety of aquatic habitats. These include saline lakes (Bayly, 1971), transitory environments such as ponds, and even puddles. In recent years, the trend has been to study these organisms from other biological aspects rather than from a purely taxonomic point …

Taxonomy, faunistics and life-history traits of Dytiscidae and Noteridae (Coleoptera) in a West African savannah
… water bodies for the aestivation of these aquatic beetles. The ecological studies focused on the question how the beetles cope with the temporary loss of their aquatic habitats during dry season. The climate in the study area is characterised by a pronounced dry season from about November …

Trophic transfer of nearshore basal resources: interpreting fatty acid and stable isotope biomarkers
Benthic heterotrophs living in aphotic aquatic habitats rely upon subsidies of detrital energy, in the form of complex organic molecules, which are synthesized by macrophytes and phytoplankton in the photic zone. Identifying the relative importance of different basal energy resources to consumers …

Population Biology and Landscape Ecology of Digenetic Trematode Parasites in their Gastropod Hosts, with Special Emphasis on Echinostoma spp.
… have at least one host capable of moving between aquatic habitats, while autogenic species have all hosts restricted to a single body of water. These life cycle categories help shape the transmission dynamics of trematode larval stages in their gastropod hosts. Allogenic parasites, particularly …

Effects of leaf litter diversity on nutrients and mosquito communities in Neotropical artificial tree holes
Inputs from terrestrial habitats to aquatic habitats are important for structuring aquatic communities. Terrestrial producer diversity in the tropics may decline due to anthropogenic causes. I investigated how tree diversity affects aquatic communities. We used leaves from three timber-producing …

What lies beneath? Fungal diversity at the bottom of the Great Lakes
… diversity has been documented from terrestrial habitats leaving aquatic habitats rarely explored. Even less is known about fungi inhabiting freshwater lakes, particularly the benthic zone that may serve as an untapped resource for fungal biodiversity. This study aimed towards understanding the …

Physical and chemical correlates of Sacramento County vernal pool crustaceans
<p>Vernal pools are temporary aquatic habitats that can be home to dozens of 4 invertebrate species. Unfortunately, over 90 percent of California vernal pool habitat has been destroyed. To better understand the remaining habitat, this study focused on the species community structure of the pools, …

Biotic Assessment Of Two Central Kentucky Streams: Examining The Effects Of Wastewater Treatment And Anthropogenic Disturbance
… anthropogenic disturbance has altered many aquatic habitats, including lotic waters. Flowing, fresh water sustains life on Earth yet suffers the resulting waste products. Native, locally adapted ecosystems integrate or eliminate the byproducts of life. However an increase of human …

Metagenomic Data Analysis Using Extremely Randomized Tree Algorithm
… range of antibiotics have often been detected in aquatic environments such as untreated and treated wastewater, river and surface water. ARG proliferation in the aquatic environment could depend upon various factors such as geospatial variations, the type of aquatic body, and the type of …

The Effect of Historic Shipwrecks on Sediment Microbiomes in the Northern Gulf of Mexico

Population Genetics of Death Valley Pupfishes (Cyprinodontidae:Cyprinodon Spp.) and the Identification of a New Retrotransposable Element Family
… Cyprinodon spp.) from the remnant aquatic habitats of Death Valley was approached by exploring the genetic structure and divergence within and among populations using mitochondrial and nuclear DNA markers. The findings of these studies illustrate the influences of population size …

RESOURCE SUBSIDIES ACROSS THE AQUATIC-TERRESTRIAL BOUNDARIES OF TEMPORARY PONDS
Aquatic habitats are closely linked to surrounding terrestrial environments via reciprocal subsidies. Much of the research on these subsidies has been focused on streams, while subsidies across aquatic-terrestrial boundaries of other aquatic systems, like temporary ponds, have received little …

Establishing Patterns in Vegetation Associations of the Fountain Darter Etheostoma fonticola in the San Marcos and Comal Rivers of Texas
Aquatic vegetation provides many services for aquatic habitats and fish communities. The Fountain Darter Etheostoma fonticola, found only in spring systems of the San Marcos and Comal rivers in central Texas, is reported to associate with vegetation for feeding, reproduction, and refuge. …

DETECTION AND OCCURRENCE OF NERODIA HARTERI (SERPENTES: COLUBRIDAE) IN AN UPPER PORTION OF THE BRAZOS RIVER WATERSHED
<p>Semiaquatic snakes are disproportionately impacted by habitat alteration adjacent to wetlands because of their reliance on both terrestrial and aquatic habitats. Brazos River Watersnakes, <em>Nerodia harteri</em>, are endemic natricines with one of the most restricted geographic ranges in North …
