Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 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.

CITES Appendix III: An underused tool for international wildlife trade regulation

open access: yesConservation Science and Practice, EarlyView.
Appendix III of CITES allows Parties to unilaterally extend domestic species protections to international trade, yet it remains vastly underused, covering just 1.3% of listed species. Drawing on the complete historical record since 1975, we show that Appendix III is most effective for endemic species and functions as a highly successful staging ...

1177. Streptocarpus aylae T.J.Edwards

open access: yesCurtis's Botanical Magazine, EarlyView.
Summary Streptocarpus aylae T.J.Edwards, a spectacular, rosette forming herbaceous perennial from cliffs of the Msikaba River in Pondoland, Eastern Cape Province, South Africa is illustrated and discussed. The species is known from only two sites and is highly localised, growing in humus rich cracks and crevices on sandstone cliffs.

Fleet Behaviour Under Economic Uncertainty: Multi‐Species Policy Scenarios for the Purse‐Seine Fishery

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Managing fishing effort remains a central challenge in achieving sustainability in many fisheries, particularly where high‐value species attract intense competition. In the Indian Ocean tropical tuna fishery, understanding how fishers respond to changing bio‐economic conditions is essential for developing effective management.

Influence of Laser Repetition Rate, Fluence and Spot Size on LA‐Q‐ICP‐MS/MS 87Sr/86Sr Precision: Insights from Apatites and Silicate Glasses

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Higher laser repetition rate, fluence and larger spot size increase signal intensity. Higher laser repetition rate produces overlaps in aerosolised particles, improving signal stability and precision. For Sr‐rich materials, moderate spot diameter (≤ 60 μm), 3 J cm‐2 fluence and ≥ 12 Hz repetition rate are recommended.

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Editorial Perspective: Expanding the search for environmental exposures related to children's development

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
In the fields of child psychology and psychiatry, countless environmental factors have been identified as correlates of children's health and development, yet each of these generally accounts for a small proportion of variance. The unaccounted‐for variation in a model may be due to measurement error, random variation, model misspecifications or ...

Improving Decision‐Making in the Identification of Tephritidae Larvae at Import in the European Union and Key to Third Instar Larvae

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The Tephritidae family, or true fruit flies, comprises approximately 250 species recognized as economically significant due to their capacity to infest commercial fruits. These pests pose serious threats to both food security and trade, and are considered quarantine pests in areas where they are not yet established. In the European Union (EU),

Contrasting population genetic structures of freshwater eels (Anguilla marmorata, A. bicolor, A. mossambica) from Madagascar

open access: yesJournal of Fish Biology, EarlyView.
Abstract Freshwater eels (genus Anguilla) are of major biological and commercial interest due to their complex catadromous life cycle and as a high‐value fishery resource, but the biology of tropical species is still poorly understood. This study investigates the genetic integrity, diversity and population structure of three species of tropical eels ...
