Regular Presence of Harbor Porpoises in the Northern Alborán Sea

open access: yesMarine Mammal Science, Volume 41, Issue 3, July 2025.
ABSTRACT The harbor porpoise (Phocoena phocoena) in the Atlantic waters of Spain and Portugal are a genetically differentiated population from the rest of the North Atlantic. They are rarely seen on the southern Atlantic coast of Spain and are thought to be extinct in the Mediterranean Sea, with scattered sightings and strandings recorded along the ...

Costs of reproduction in flowering plants

open access: yesNew Phytologist, Volume 247, Issue 1, Page 55-70, July 2025.
Summary Costs of reproduction arise when investments into current reproduction reduce future reproductive fitness. Studies on reproductive costs use diverse approaches, including the analysis of gene expression, physiology, trade‐offs between reproduction and growth/survival, and the impact of reproductive investments on population growth.

Diversification of CLE expression patterns and nonmeristematic roles for CLAVATA receptor‐like kinases in a moss

open access: yesNew Phytologist, Volume 247, Issue 1, Page 325-340, July 2025.
Summary The CLAVATA pathway controls meristematic cell proliferation and multiple nonmeristematic processes in Arabidopsis development. While CLAVATA ancestrally regulates meristematic proliferation in nonseed plant gametophytes, ancestral sporophytic and nonmeristematic functions in land plants are unknown. Here, we analysed the promoter activities of

Maternal haploid induction in maize via mutation of Gamete Expression protein 1

open access: yesPlant Biotechnology Journal, Volume 23, Issue 7, Page 2595-2607, July 2025.
Summary Doubled haploid (DH) technology, based on haploid induction (HI), is a crucial tool in enhancing crop‐breeding efficiency and has been successfully applied in various plant species. While many HI‐related genes have been identified using diverse strategies, the genetic basis and molecular mechanisms underlying HI remain incompletely understood ...

Ultrasonographic Appearance of the Deferent Ducts in Dogs without Genitourinary Disease

open access: yesVeterinary Radiology &Ultrasound, Volume 66, Issue 4, July 2025.
ABSTRACT In veterinary medicine, deferent ducts are described as being visible on ultrasound only when pathologically enlarged. Abnormal ultrasonographic enlargement of the deferent ducts has primarily been described secondary to infectious and neoplastic diseases; however, no studies have evaluated the normal ultrasonographic features of these ...
