Octopus cyanea is a commercially important cephalopod in the Western Indian Ocean (WIO) region, but scientific information to inform management strategies for species limited. A study was conducted 2014, 2015, 2017 and 2018 investigate biological parameters including growth, mortality, exploitation rates recruitment patterns sea around Mafia Archipelago, Tanzania. Virtual population analysis (V...

Density-independent and density-dependent variables both affect the spatial distributions of species. However, their effects are often separately addressed using different analytical techniques. We apply a spatially explicit regression framework that incorporates localized, interactive and threshold effects of both density-independent (water temperature) and density-dependent (population abunda...

The Atlantic surfclam (Spisula solidissima) is an important commercial fishery resource on the U.S. MidAtlantic continental shelf. Although 2016 stock assessment found that surfclams are neither overfished nor overfishing occurring, uncertainty in scale of spawning biomass persists. As a consequence this uncertainty, Fishery Management Council (MAFMC) lowered acceptable biological catch 2016. A...

Coral reefs, the most diverse of marine ecosystems, currently experience unprecedented levels of degradation. Diseases are now recognized as a major cause of mortality in reef-forming corals and are complicit in phase shifts of reef ecosystems to algal-dominated states worldwide. Even so, factors contributing to disease occurrence, spread, and impact remain poorly understood. Ecosystem resilien...

The characterization of biomass and its dynamics provides valuable information for the assessment of natural and transplanted eelgrass populations. The need for simple, nondestructive assessments has led to the use of the leaf biomass-to-length ratio for converting leaf-length measurements, which can be easily obtained, to leaf growth rates through the plastochrone method. Using data on leaf bi...

Background. Herbivores play a critical role in structuring benthic communities on tropical coral dominated reefs because they remove macro and microalgae, which might otherwise overgrow adult corals or prevent successful recruitment of juveniles. Reducing herbivory has been implicated in promoting phase shifts from coral dominance to other ecosystem states following acute disturbances. Turbidit...

The status of fishery resources in the Yangtze estuary and its adjacent waters is still unclear for effective implementation management strategies. To help address this gap, a new method especially data-limited fish stocks (LBB) was applied to assess seven commercially ecotrophically important stocks. Fish specimens were collected by bottom trawling quarterly from May 2018 February 2019. Two hi...

Fishery resources play an important role in the national economy and ecological diversity China; it is of great significance to evaluate rationally exploit fishery resources. Most fisheries off coast China are data-limited, as complex assessment models not suitable for its resource assessment. Therefore, data-limited among current research hotspots. In this paper, two new (Bayesian state–space ...

We hydrothermally treated monocultures of Escherichia coli, Pseudomonas putida, Bacillus subtilis, and Saccharomyces cerevisiae at isothermal (350 °C for 60 min) and fast (rapid heating for 1 min) liquefaction conditions. Fast hydrothermal liquefaction (HTL) of P. putida and S. cerevisiae produced the highest biocrude yields of 47 ± 13 and 48 ± 9 wt %, respectively. Biocrudes generated via fast...
