A current concern for many freshwater bodies is the rising number of invasive Rusty Crayfish (Oroconectes rusticus) an aggressive species that can potentially harm the freshwater ecosystem they inhabit. This can be done ...

The objective of our study was to identify the pattern of the distribution of earthworms and ground-dwelling invertebrates on the upper and the lower terraces of Putnam Park.

Crayfish are important to study because they are ecosystem engineers that are often an invasive species and that are pivotal in predator-prey interactions (Townsend 2004, Olden et al. 2005). Calcium levels along with ...

Our study investigated crayfish abundance patterns in Little Niagara Creek. We initially hypothesized that crayfish numbers would differ between riffles and pools as suggested by Clark et al. (2013). Pools can be ...

Leaf litter is a vital source of nutrients for stream-dwelling organisms and the rate at which these nutrients are released by decomposition is important to the overall functioning of the stream1. Both microorganisms and ...

Algal blooms are associated with high nutrient concentrations and can pose problems for freshwater ecosystems, the organisms they contain, and humans that benefit from them. Nutrients that are usually a limiting factor ...

From the time of the last glaciation, earthworms were absent from northern soils, until non-native species were accidently imported from Europe in the 1600’s. Earthworms are “ecosystem engineers” that can modify soil ...

Organic matter decomposition is an important ecological process in stream ecosystems. Decaying leaves in particular constitute an important source of food and habitat for microorganisms and macroinvertebrate “shredders,” ...

The Escalante River is the last remaining free-flowing river of its size in the western United States, and it faces environmental threats from the invasive Russian olive tree, Elaeagnus angustifolia (Reynolds and Cooper ...

The Escalante River ecosystem, like many across the southwestern United States, is threatened by invasive Russian olives trees (Elaeagnus angustifolia).Russian olives are drought tolerant nitrogen-fixers that form dense ...
