Effects of fishing during the spawning period: implications for management
, 2010 Avoidance of fishing during the spawning season has been proposed as a contribution to achieving sustainable exploitation. Here we review the biological effects of fishing during the spawning period and explore their implication on sustainable management.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This work fabricated MOF‐based woven absorbing fabrics with dimensional engineering via a wet spinning strategy. The absorbing fabrics achieve a reflection loss of −51.47 dB at 2.9 mm, with an effective absorption bandwidth reaching 3.54 GHz. The absorbing fabrics can be freely bent, stretched, and folded, with individual fibers exhibiting a break ...

Toxics, 2016 Reproductive success manifested by spawning and fertilization, in most fish, depends partly on an appropriate courtship behavior by both sexes. The zebrafish reproductive behavior can be resolved in some of its constituent elements by a computerized ...

Managing for resilience with ecological structure: Portfolio effects in the Laurentian Great Lakes
Frontiers in Ecology and the Environment, EarlyView.Combined effects of global change, including land conversion, biological invasions, and overexploitation, have degraded the resilience of ecosystems and the services they provide. Here, we identify key ecological structures and processes that can be targeted by management to improve resilience at scales ranging from single species to entire landscapes.

A Blend of F Prostaglandins Functions as an Attractive Sex Pheromone in Silver Carp
Fishes, 2019 A series of laboratory experiments tested the hypothesis that the Silver Carp (Hypophthalmichthys molitrix), an invasive river carp from China, employs a prostaglandin F2α-derived sex pheromone that is attractive and species-specific.

Inducing broadcast coral spawning ex situ: Closed system mesocosm design and husbandry protocol [PDF]
, 2017 For many corals, the timing of broadcast spawning correlates strongly with a number of environmental signals (seasonal temperature, lunar, and diel cycles). Robust experimental studies examining the role of these putative cues in triggering spawning have

Health Economics, EarlyView.ABSTRACT Even though data on hospital admissions are widely used in health research, hospitalization‐related estimands measured using these data are not always clearly conceptualized. Consequently, estimators of these quantities can have unclear rationales and undesirable properties.

RESULTS OF PIKE PERCH SANDER LUCIOPERCA INTRODUCTION IN LAKE KHANKA
Известия ТИНРО, 2018 Pike perch was introduced into Lake Khanka in 1970–1978. The introduction was founded on concept of low commercial productivity of the lake prevailed in those times. For the past 50 years, the species acclimatized successfully in the lake.
