Critical knowledge gaps in the conservation and restoration of cold‐water corals

Restoration Ecology, EarlyView.
Abstract Introduction Critical knowledge gaps hamper effective conservation of threatened cold‐water coral (CWC) ecosystems, facing cumulative anthropogenic and climate pressures. This review provides a strategic roadmap for urgent, informed intervention.

ATR/Mec1 prevents lethal meiotic recombination initiation on partially replicated chromosomes in budding yeast

eLife, 2013
During gamete formation, crossover recombination must occur on replicated DNA to ensure proper chromosome segregation in the first meiotic division. We identified a Mec1/ATR- and Dbf4-dependent replication checkpoint in budding yeast that prevents the ...

Reproductive biology of carpenter seabream (Argyrozona argyrozona) (Pisces: Sparidae) in a marine protected area [PDF]

, 2005
The carpenter seabream (Argyrozona argyrozona) is an endemic South African sparid that comprises an important part of the handline fishery. A three-year study (1998−2000) into its reproductive biology within the Tsitsikamma National Park revealed that ...

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

ketu mutant mice uncover an essential meiotic function for the ancient RNA helicase YTHDC2

eLife, 2018
Mechanisms regulating mammalian meiotic progression are poorly understood. Here we identify mouse YTHDC2 as a critical component. A screen yielded a sterile mutant, ‘ketu’, caused by a Ythdc2 missense mutation. Mutant germ cells enter meiosis but proceed

Chamber‐by‐Chamber Measurements of Planktonic Foraminiferal Mg, Sr, and Na to Ca Ratios With Femtosecond LA‐ICP‐MS

Rapid Communications in Mass Spectrometry, Volume 40, Issue 7, 15 April 2026.
ABSTRACT Rationale Distribution patterns of foraminifera are controlled by environmental parameters such as temperature, salinity, and nutrient concentrations in each water mass. Since trace elements to Ca ratios of marine microfossil calcite test of foraminifera record environmental and ecological habitat information, we used femtosecond (fs) LA‐ICP ...

Determining the Environmental Drivers of Greenshell Mussel (Perna canaliculus) Spat Settlement

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Globally, mussel aquaculture production is often constrained by a limited supply of spat, the juvenile stage of mussels, used to initiate production. In some instances, the harvesting of wild spat on spat‐collection ropes has the potential to quickly solve this acute shortage. However, the settlement of mussel spat on collectors is known to be

Homo sapiens, industrialisation and the environmental mismatch hypothesis

Biological Reviews, Volume 101, Issue 2, Page 580-601, April 2026.
ABSTRACT For the vast majority of the evolutionary history of Homo sapiens, a range of natural environments defined the parameters within which selection shaped human biology. Although human‐induced alterations to the terrestrial biosphere have been evident for over 10,000 years, the pace and scale of change has accelerated dramatically since the onset
