Electrospun Fibers of Polyhydroxyalkanoate/Bacterial Cellulose Blends and Their Role in Nerve Tissue Engineering

open access: yesMacromolecular Materials and Engineering, EarlyView.
Electrospun nanofibers from bacterial cellulose and polyhydroxyalkanoates (PHAs) offer sustainable bio‐derived scaffolds. These novel eco‐friendly materials demonstrate good cytocompatibility with NG108 neuronal cells. The blend approach enables the creation of versatile materials with tunable properties, openingp avenues for various tissue engineering

Drift Foraging by Allopatric and Sympatric Atlantic Salmon and Brown Trout Parr Under Rapid Flow Fluctuations

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Hydropeaking may result in behavioral responses in riverine organisms that experience rapid flow fluctuations. In stream fish, the balance between energy spent on swimming and foraging vs. food intake affects fitness, a balance strongly influenced by flow conditions.

Environmental Parameters as Indicators of Bear Welfare

open access: yesZoo Biology, EarlyView.
More than half of the bear exhibits in Thai zoos do not provide the environmental resources needed for good welfare potential. Accredited zoos provided better exhibits than government and private zoos. ABSTRACT Bears are commonly displayed in zoos worldwide.

The Benthic Underwater Microscope imaging PAM (BUMP): A non‐invasive tool for in situ assessment of microstructure and photosynthetic efficiency

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Essential to life on Earth, assessment of marine photosynthesis is of paramount importance. Photosynthesis occurs in spatially discrete microscopic entities at various levels of biological organization, from subcellular chloroplasts to symbiotic microalgae and macroalgae, and is influenced by the surrounding conditions.

Field Guide to Nonindigenous Marine Fishes of Florida [PDF]

open access: yes, 2009
The purpose of this field guide is to provide information on nonindigenous (i.e., non-native) fishes that have been observed in Florida’s marine waters. Introductions of non-native marine fishes into Florida’s waters could be intentional or unintentional,

Giant water clusters: where are they from?

open access: yes, 2018
A new mechanism for the formation and destruction of giant water clusters described in the literature is proposed. We have earlier suggested that the clusters are associates of liquid crystal spheres (LCS), each of which is formed around a seed particle,

Estuarine Nitrifiers: New Players, Patterns and Processes [PDF]

open access: yes, 2010
Ever since the first descriptions of ammonia-oxidizing Bacteria by Winogradsky in the late 1800s, the metabolic capability of aerobic ammonia oxidation has been restricted to a phylogenetically narrow group of bacteria.
