Ecology of common bully (Gobiomorphus cotidianus) in the Tarawera and Rangitaiki rivers: isolation by inland distance or anthropogenic discharge? [PDF]

, 2009
Previous research has identified distinct genetic, life-history and reproductive differences between populations of common bully (Gobiomorphus cotidianus) upstream and downstream of a pulp and paper mill outfall on the Tarawera River in the Bay of Plenty,

Nest reuse in arctic‐breeding shorebirds: an analysis of potential benefits and factors affecting the occurrence of this rare behavior

Journal of Avian Biology, 2018
During a 13‐yr study near Utqiaġvik (formerly Barrow), Alaska, we documented the prevalence of nest reuse in eight arctic‐breeding shorebirds. We evaluated whether nest reuse saved individuals time and energy, enhanced nest survival, or was related to ...

Biocomplexity in a highly migratory pelagic marine fish, Atlantic herring [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2006
The existence of biologically differentiated populations has been credited with a major role in conferring sustainability and in buffering overall productivity of anadromous fish population complexes where evidence for spatial structure is uncontroversial.

Temperature tolerance of European fish species based on thermal maxima in southern Baltic Sea-basin streams

Ecological Indicators
Evaluation of the thermal requirements of fish species is particularly important given ongoing climate change and warming trends. Assessing thermal tolerance reveals the potential a species has to persist, spread, or disappear.

Conservation significance of alternative nests of golden eagles

Global Ecology and Conservation, 2015
Golden eagles (Aquila chrysaetos) are long-lived raptors that maintain nesting territories that may be occupied for a century or longer. Within occupied nesting territories there is one nest in which eagles lay their eggs in a given year (i.e., the used ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Assessing sustainable lethal take for great blue heron in the northeastern United States

Wildlife Society Bulletin
Conflicts between humans and avian species protected under the Migratory Bird Treaty Act regularly occur. As such, there is a need to sustainably manage negative effects caused by birds (e.g., economic loss, risks to human health and safety) in a manner ...
