Leiomyoma Causing Disease in a Wild Adriatic Sturgeon (Acipenser naccarii , Bonaparte, 1836)

Journal of Fish Diseases, EarlyView.
ABSTRACT The Adriatic sturgeon, Acipenser naccarii, is an endemic species to the Adriatic Sea basin classified as critically endangered according to the IUCN Red List. Limited information is available regarding the health status and diseases affecting this species, particularly in the wild.

Ancient mitochondrial DNA analyses of Iberian sturgeons

, 2009
Summary Today’s European sturgeons are relics of erstwhile widely distributed populations, diminished mainly by overfishing and habitat changes over the centuries.

Long Distance Migration of Beluga (Huso huso) and Stellate Sturgeon (Acipenser stellatus) in Lower Danube River in Relation with Iron Gate II Dam

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Animal Science and Biotechnologies, 2018
Construction of the dams in Lower Danube River (LDR- rkm 0 Sulina – rkm 1075 Baziasi) without fish passages, as well as illegal fishery and river bottom modification due to navigation had negative impact on sturgeon’s populations.

Monoicy, dioicy, and genetic structure in three species of Sheathia (Batrachospermales, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract Sexual systems (i.e., separate vs. combined sexes) vary widely among eukaryotes and influence the evolution of reproductive systems, which shape genetic structure and evolutionary trajectories. In diploid‐dominant angiosperms, combined (i.e., hermaphroditism) and separate sexes are expected to correlate with selfing and outcrossing ...

Pollock and Sturgeon on defeaters

Synthese, 2016
Scott Sturgeon has recently challenged Pollock’s account of undercutting defeaters. The challenge involves three primary contentions: (1) the account is both too strong and too weak, (2) undercutting defeaters exercise their power to defeat only in conjunction with higher-order beliefs about the basis of the lower-order beliefs whose justification they

Religiosity, Religious Orientation, and a Good Night's Sleep: The Role of Anxiety and Depression

Journal of Sleep Research, EarlyView.
ABSTRACT Religious belief can be beneficial to mental health, particularly in relation to anxiety and depression, both of which are strongly linked to poor sleep. This study aimed to investigate the role of anxiety and depression as mediators in the relationship between religiosity/religious orientation and sleep health in the Druze community in Israel.

Human Impacts on Great Lakes Walleye Sander vitreus Structure, Diversity and Local Adaptation

Molecular Ecology, EarlyView.
ABSTRACT Artificial propagation and wild release may influence the genetic integrity of wild populations. This practice has been prevalent in fisheries for centuries and is often termed ‘stocking’. In the Laurentian Great Lakes (Great Lakes here‐on), walleye populations faced declines from the 1950s to the 1970s, prompting extensive stocking efforts ...

Genome Architecture and Speciation in Plants and Animals

Molecular Ecology, EarlyView.
ABSTRACT There have been numerous treatments of specific topics in speciation, but surprisingly few papers have compared patterns and processes of speciation across different organismal groups. In this review, we partially address this gap by asking how variation in genome architecture impacts speciation across the plant and animal kingdoms.

The cognitive role of concept variability

Mind &Language, EarlyView.
I present and defend concept variability, the view that concepts can admit of indefinitely many variations and changes in their representational contents without thereby losing their identity. I argue that the variability of concepts is central to their role in enabling cognition, and thus that a concept's content variability is, despite philosophical ...
