Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Phylogenomic analysis of ultraconserved elements clarifies relationships and morphological evolution in Cryptoplacoidea (Mollusca: Polyplacophora)

open access: yesCladistics, EarlyView.
Abstract Targeted enrichment of ultraconserved elements (UCEs) is a powerful tool for resolving phylogeny in groups with limited morphological or molecular data. Here, we use UCEs to reconstruct the first comprehensive phylogeny of the chiton superfamily Cryptoplacoidea, including museum material up to 133 years old.

Enhancing the fastness characteristics of weld‐dyed cotton and recycled nylon 6,6 fabrics via sodium alginate and titanium dioxide

open access: yesColoration Technology, EarlyView.
Abstract This study investigates a sustainable dyeing and finishing strategy for recycled nylon 6,6 and organic cotton fabrics dyed with weld. Following meta‐mordant dyeing using alum under Natural Organic Dye Standard (NODS)‐compliant conditions, the fabrics were subjected to functional finishing with titanium dioxide as a multifunctional ...

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

open access: yesThe 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

open access: yesThe 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

open access: yesThe 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

open access: yesJournal 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

open access: yesJournal 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 ...

Nature and timing of dysregulation associated with pseudoalbinism in California Halibut, Paralichthys californicus

open access: yesJournal of Fish Biology, EarlyView.
Abstract Pseudoalbinism in flatfishes, the absence of melanophores or melanin over most of the ocular side of the body, is often observed in hatcheries. The prevalence of pseudoalbinism can be very high, sometimes exceeding 90% of individuals in California Halibut, Paralichthys californicus.

Long‐term crucian carp (Carassius carassius) resilience to duckweed (Lemnaceae) dominance in a small eastern English pond

open access: yesJournal of Fish Biology, EarlyView.
Abstract Successful scientifically informed fish conservation requires a good knowledge of how fishes have and will be affected by multiple stresses over the decadal‐centennial timescales relevant to real‐life fish‐environment responses. By combining palaeoecological and monitoring data (regular sampling over 16 years), we studied the long‐term ...
