Harnessing plant‐based platform for low‐cost cellulosic sugar recovery from bioenergy crops

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The price of pure cellulase enzyme for the recovery of fermentable cellulosic sugars is one of the major challenges that limit the commercialization of second‐generation biofuels and bio‐based products. This work shows a means to greatly reduce the cost of cellulases. The abundant capacity of plants to synthesize and hyperaccumulate transgenic

Biographies, ontological security and the socio‐spatial politics shaping teachers' mobility in remote Australia

open access: yesBritish Educational Research Journal, EarlyView.
Abstract The global teacher shortage continues to intensify, with disparate impacts across geographic and socio‐economic communities. In Queensland, Australia, where this study originates, post‐COVID teacher shortages have intensified workforce pressures, leaving several regional, rural and remote schools as some of the ‘hardest‐to‐staff’ in the ...

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

The fish pituitary directly responds to daylength and drives seasonality

open access: yesProceedings of the Royal Society B: Biological Sciences
Seasonal timing is important for many critical life history events of organisms, and annual changes in daylength provide a reliable seasonal cue. In birds and mammals, photoperiod-driven seasonality is caused by changes in pituitary thyroid stimulating hormone (TSH), brain deiodinase (DIO) and triiodothyronine (T

Spawning closures: ecological and economic trade-offs in management of mixed demersal flatfish fisheries in the North Sea

open access: yes, 2011
The contribution of spawning closures to sustainable management of North Sea flatfish fisheries is explored using a spatial and temporal explicit model of four target species (sole, plaice, turbot and brill) and two bycatch species (cod, rays).

Flight of the dragons: a global review of migration in Odonata

open access: yesBiological Reviews, EarlyView.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.

A before after control impact experiment on a historically fished seagrass (Zostera marina) bed

open access: yesConservation Science and Practice
Seagrasses are considered to be globally important for carbon sequestration and they provide a range of ecosystem services. However, they are also known to be vulnerable to various anthropogenic activities, not least bottom contacting fishing gears such ...
