Accurate establishment of baseline conditions is critical to successful management and habitat restoration. We demonstrate the ability to robustly estimate historical fish community composition and assess the current status of the urbanized Barton Creek watershed in central Texas, U.S.A. Fish species were surveyed in 2008 and the resulting data compared to three sources of fish occurrence infor...

Several regions in the Unites States have developed algal bioassessment methods for wadeable streams (e.g. Maine, Connecticut). Algal communities and indicator species are correlated with land use, water chemistry, other watershed metrics to identify ecosystem indicators relevant local conditions. Taxonomic analysis has historically been performed by microscopic examination identification of wi...

Assessing food web structural properties and energy fluxes under changing hydrological regimes water quality reveals the temporal patterns of ecosystem dynamics in shallow lakes. Here, we studied northern China’s largest lake (Lake Baiyangdian) using quantitative models for five representative years (1958, 1980, 1993, 2009, 2019). We analyzed structure function by combining a Bayesian isotope m...

In this paper, we study the class of of C3-like Finsler metrics which contains the class of semi-C-reducible Finsler metric. We find a condition on C3-like metrics under which the notions of Landsberg curvature and mean Landsberg curvature are equivalent.

in this paper the general relatively isotropic l -curvature finsler metrics are studied. it isshown that on constant relatively landsberg spaces, the concepts of weakly landsbergian, landsbergianand generalized landsbergian metrics are equivalent. some necessary conditions for a relativelyisotropic l -curvature finsler metric to be a riemannian metric are also found.

of a thesis at the University of Miami. Thesis supervised by Professor Daniel D. Benetti. No. of pages in text. (38) Efforts to reduce the use of fishmeal in aquafeeds for carnivorous marine fish have been a focal point of aquaculture nutrition research in recent years. Building upon such research, this study was designed to compare the digestibility, growth and performance of three soy protein...

—From 1993 to 1996, fish assemblage data were collected from 309 wadeable streams in the U.S. Mid-Atlantic Highlands region as part of the U.S. Environmental Protection Agency’s Environmental Monitoring and Assessment Program. Stream sites were selected with a probabilistic sampling design that allowed regional estimates of stream condition. We examined responses of 58 fish assemblage metrics t...
