Management applications of genetic structure of anadromous sturgeon populations in the Lower Danube River (LDR), Romania [PDF]
Scientific Annals of the Danube Delta Institute, 2013 During the last decades, the over-exploitation of sturgeon stocks for caviar production simultaneously with severe habitat deteriorations has led to drastic declines in the natural populations of the Danube River. As a result of (i) decrease of sturgeon

Status of Florida’s pillar coral population: in situ declines and ex situ successes
Frontiers in Marine ScienceThe population of pillar coral, Dendrogyra cylindrus, in Florida was decimated from 2013 to 2020, primarily by the emergence of stony coral tissue loss disease (SCTLD).

Entrepreneurial Spawning and Firm Characteristics [PDF]
Management Science, 2011 We analyze the implications of the decision to spawn or to retain a new product for the nature and evolution of the firm. In our model, a new product is spawned if the fit between the product and its parent firm organization is not adequate. We focus on the impact of the firm's history of spawning decisions on firm characteristics such as size, focus ...

Flavin Catalysts in Organic Synthesis
Angewandte Chemie, EarlyView.Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Sound from spawning cod at their spawning grounds [PDF]
ICES Journal of Marine Science, 1999 Sound was recorded at five stations at and near the main spawning grounds of the northeast Arctic cod (Gadus morhua L.) off the Lofoten Islands, Norway. Recordings were carried out during April 1997 when large numbers of cod aggregated to spawn, and were repeated in September when the cod were no longer spawning and, in fact, most had emigrated.

Advanced Science, EarlyView.ABSTRACT High‐fat diet (HFD)‐induced hepatic injury represents a pathology observed across vertebrates, yet the underlying mechanisms remain incompletely understood. Herein, the present study identifies phosphatidylethanolamine methyltransferase (Pemt), a key enzyme in phosphatidylcholine synthesis, as a critical regulator of mitochondrial homeostasis ...
