Proliferative Kidney Disease in Sympatric Naturally Reproducing Populations of Rainbow and Brown Trout in Southern Peri‐Alpine Germany

Aquaculture, Fish and Fisheries
The decline of central European salmonid populations is exacerbated by global warming impacts on disease and interspecific competition. In this context, sympatric naturally reproducing populations of rainbow trout Oncorhynchus mykiss and brown trout ...

Quantitative Estimates of Nutrient Inputs From Angling Baits in Lakes Supporting Different Recreational Fisheries

Fisheries Management and Ecology, EarlyView.
ABSTRACT Recreational anglers use ground baiting to attract fish and increase catch inputs organic matter that can have important effects on water quality by increasing eutrophication. However, nutrient inputs from angling bait by recreational fisheries have not yet been estimated.

Reproductive sterility in aquaculture: A review of induction methods and an emerging approach with application to Pacific Northwest finfish species

Reviews in Aquaculture, Volume 15, Issue 1, Page 220-241, January 2023., 2023
Abstract Aquaculture is the fastest‐growing food‐production sector and is striving to become a long‐term sustainable approach to meet the rising global demand for seafood. During the expansion and advancement of aquaculture, minimizing ecological impacts should occur concomitantly with maximizing production. Farmed fish, often genetically distinct from

On the Nonexistence of Nontrivial Involutive n-Homomorphisms of C*-algebras [PDF]

arXiv, 2007
An n-homomorphism between algebras is a linear map $\phi : A \to B$ such that $\phi(a_1 ... a_n) = \phi(a_1)... \phi(a_n)$ for all elements $a_1, >..., a_n \in A.$ Every homomorphism is an n-homomorphism, for all n >= 2, but the converse is false, in general. Hejazian et al.

Combinatorial Dark Energy [PDF]

arXiv, 2012
In this paper, we give a conceptual explanation of dark energy as a small negative residual scalar curvature present even in empty spacetime. This curvature ultimately results from postulating a discrete spacetime geometry, very closely related to that used in the dynamical triangulations approach to quantum gravity.

Past research and future directions in understanding how birds use their sense of smell

Ibis, EarlyView.
Our understanding of the functional importance of olfaction to birds has improved over the past 60 years, largely as the result of experimental studies testing how birds use their sense of smell in different contexts. As it is impossible to measure directly which odours birds can detect, we rely on measuring behavioural responses to scent cues or ...
