New dolabellanes from the marine alga dictyota pardalis f.pseudohamata

, 1994
An investigation of the natural products chemistry of the brown alga Dictyota pardalis f. pseudohamata collected from the Magnetic Island, Australia, yielded five new dolabellane type diterpenes (1–5) and the previously reported compounds 6–10.

Compromised DNA replication in gut cells underlies sensitivity to genotoxic stress in the tardigrade Hypsibius exemplaris

The FEBS Journal, EarlyView.
DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

Structural insights into θ‐type carbonic anhydrases 3 and 4: Tuning the directionality of CO2 hydration in a diatom

The FEBS Journal, EarlyView.
θ‐CA3 from a marine diatom has an N‐terminal transmembrane helix and two homologous catalytic domains. The enzyme functions as a dimer, with active sites formed near the dimer interface. A bicarbonate ion binds on the symmetry axis of the dimer and forms hydrogen bonds with both monomers, thereby activating θ‐CA3 and tuning CO2 hydration activity ...

Reactive oxygen species, antioxidants and the regulation of plant development

The FEBS Journal, EarlyView.
The regulation of axillary bud outgrowth by the interplay between phytohormone and redox signals. Axillary bud outgrowth is regulated by cellular energy status and the balance between phytohormones, notably abscisic acid (ABA) and gibberellic acid (GA).

Divergent exploratory‐avoidant behavioural strategies may drive niche differentiation in juvenile Antarctic fishes

Journal of Fish Biology, EarlyView.
Abstract We used an ecological niche theory framework integrating physiological and behavioural ecology to understand interspecific differentiation of juveniles of four Antarctic fishes: Trematomus bernacchii, Trematomus pennellii, Trematomus nicolai and Pagothenia borchgrevinki.

Food selectivity and grazing responses of the Lawnmower Blenny (Salarias fasciatus) to nutrient enrichment and ammonia exposure

Journal of Fish Biology, EarlyView.
Abstract Nutrient enrichment can alter the nutritional quality of the epilithic algal matrix (EAM) and modify the feeding environment of herbivorous and detritivorous reef fishes. However, wastewater inputs can also elevate ammonia concentrations, which may disrupt fish physiological processes, yet the effects of ammonia exposure on grazing activity ...
