Response of riparian vegetation to short‐ and long‐term hydrologic variation

Ecological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract Increasing demand for river water now conflicts with an increasing desire to maintain riparian ecosystems. Efficiently managing river flows for riparian vegetation requires an understanding of the time scale of flow effects, but this information is limited by the absence of long‐term studies of vegetation change in response to flow variation ...

Concepts of Value for Marine Recreational Fishing [PDF]

American Journal of Agricultural Economics, 1978
fishing. The benefit-cost criterion is one guide for making these decisions. This paper focuses on procedures for estimating changes in marine recreational fishing benefits under resource management options. The theoretical basis for such estimation is clear and there are a number of good studies to guide the research. With benefit-cost analysis, it is

Collective orientation of an immobile fish school, effect on rheotaxis [PDF]

Phys. Rev. E 103, 022137 (2021), 2020
We study the orientational order of an immobile fish school. Starting from the second Newton's law, we show that the inertial dynamics of orientations is ruled by an Ornstein-Uhlenbeck process. This process describes the dynamics of alignment between neighboring fish in a shoal, a dynamics already used in the literature for mobile fish schools. Firstly,

Assessing the Impact of Chemical Algae Management Strategies on Anurans and Aquatic Communities

Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 213-224, January 2023., 2023
Abstract Pond management with chemical and biological agents that reduce overgrowth of algae is an important means of maintaining water quality in residential ponds, yet the effects on nontarget species are not fully understood. We assessed the impact of Aquashade (a common nontoxic pond dye) and copper sulfate (a toxic algaecide) on American toad ...
