Genomic Signatures in Maned Three‐Toed Sloths From Ancient to Recent Environmental Changes in Brazil's Threatened Atlantic Forest

Molecular Ecology, EarlyView.
ABSTRACT Environmental and climatic changes have shaped the evolutionary trajectories of natural populations, leaving genomic signatures that reflect how species respond to these shifts and their impacts on genetic health. While these insights are essential for unravelling evolutionary histories and informing conservation strategies, studies on ...

Ticks and tick‐borne bacterial pathogens found on hard ticks (Acari: Ixodidae) on cattle in the Central River region of The Gambia

Medical and Veterinary Entomology, EarlyView.
First detection of Ehrlichia minasensis, Anaplasma marginale and hemotropic Mycoplasma spp. in cattle in The Gambia. Identification of four tick species, with Hyalomma marginatum being the most common. 15.6% of ticks tested positive for tick‐borne pathogens, including Ehrlichia spp., A. marginale and hemotropic Mycoplasma spp.

Specimen‐tailored ‘lived’ climate reveals precipitation onset and amount best predict specimen phenology, but only weakly predict estimated reproduction across a clade

New Phytologist, EarlyView.
Summary Herbarium specimens are widely distributed in space and time, thereby capturing diverse conditions. We reconstructed specimen ‘lived’ climate from knowledge of germination cues and collection dates for 14 annual species in the Streptanthus (s.l.) clade (Brassicaceae) to ask: which climate attributes best explain specimen phenological stage and ...

Population‐wide single‐pollen nuclei genotyping in rye sheds light on the genetic basis and environmental plasticity of meiotic recombination

New Phytologist, EarlyView.
Summary The core molecular machinery of meiosis is conserved deep across eukaryotic lineages. Nevertheless, recombination landscapes vary at multiple scales, from chromosomes to populations, caused by an interaction between genetic and environmental factors.
