River Ecosystem Concepts and Hydrogeomorphology

Landscape ecologists study physical, chemical, and biological interactions among multiple ecosystems. In the case of the highly interdisciplinary riverine landscape ecology, the focus is on studies of the four-dimensions of rivers (longitudinal, lateral, vertical, and temporal), with a particular emphasis on interactions between the wetted riverscape and the occasionally wetted floodscpae. Riverine landscape ecologists view … Continue reading River Ecosystem Concepts and Hydrogeomorphology

Microplastic pollution

Plastic debris, the majority of which is microscopic (<1mm), has been reported in every open ocean and many freshwater lakes and river. Microplastics enter aquatic habitats through a variety of sources, and are bioavailable to a wide range of vertebrates and invertebrates, resulting in many adverse health effects. Recently, efforts to quantify the amount of … Continue reading Microplastic pollution

Lake benthos invertebrate distribution

The distribution of benthic invertebrates is affected by physical, chemical, and biological processes. These processes interact to create distinct niches, however little research has been conducted on benthic-pelagic interactions. We investigated benthic invertebrate depth distribution in a protected Kansas reservoir with a deep metalimnetic photosynthetic community (DCM). The reservoir has a protected watershed managed by … Continue reading Lake benthos invertebrate distribution

River primary production and metabolism

Ecosystem ecology encompasses the interactions between biotic (community attributes) and abiotic components of a system. Ecosystem studies focus on defining and exploring functional processes, including nutrient cycling, decomposition, and primary productivity, or the amount of carbon fixed in an ecosystem. In aquatic ecosystems, gross primary productivity (GPP) and respiration (R) can be measured using diel … Continue reading River primary production and metabolism
