Impact of endometrial thickness on reproductive outcome in fresh and frozen–thawed embryo transfer: systematic review and meta‐analysis

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 3, Page 271-281, September 2025.
ABSTRACT Objective To evaluate the impact of endometrial thickness on the reproductive outcomes of embryo transfer (ET) treatments using both cut‐off‐based meta‐analysis and meta‐analysis of proportions. Methods This was a systematic review and meta‐analysis of comparative studies (randomized controlled trials, cohort studies, case–control studies) and

Water‐saving strategies in rice farming entail cascading effects in prey–predator interactions across ecosystem boundaries

Journal of Applied Ecology, Volume 62, Issue 9, Page 2273-2282, September 2025.
These results show that introducing multiple drainage periods in rice fields (i.e. AWD) indirectly hampers terrestrial spider reproduction through limiting the emergence of potential preys from the aquatic to terrestrial boundaries. MSD resulted in a more conciliatory strategy as it largely reduces methane emissions and does not affect predator–prey ...

Relación entre la densidad de anidación y el éxito reproductivo en el Piquero de Nazca (Sula granti), Isla de la Plata, Ecuador [PDF]

, 2017
Multiple hypotheses have been proposed to explain the prevalence of the habit of colonial nesting in seabirds. In the Nazca bobby (Sula granti), a marine bird with colonial nesting, the reproductive success is apparently determined by factors such as ...

ARABIDOPSIS HOMOLOG OF TRITHORAX1 impacts lateral root development by epigenetic regulation of targets involved in root system architecture

New Phytologist, Volume 247, Issue 5, Page 2180-2195, September 2025.
Summary Developmental processes are regulated at multiple levels, including the epigenetic level. Among the epigenetic factors, histone H3 lysine 4 (H3K4) methyltransferases contribute to active transcription of target genes, and here, we explored how the H3K4 methyltransferase ARABIDOPSIS HOMOLOG OF TRITHORAX1 (ATX1) affects Arabidopsis thaliana ...

Condición física de los Piqueros de Nazca (Sula granti) durante el período de anidación [PDF]

, 2017
Seabirds undergo a notable change in their physical condition (i.e., fluctuations in their weight) as a consequence of the high energetic demand for reproduction both in hatching but particularly during brood rearing.

Delineating ecologically distinct groups for annual cycle management of a declining shorebird

Journal of Applied Ecology, Volume 62, Issue 5, Page 1152-1165, May 2025.
Using measurements of migratory connectivity in concert with expert opinion can define ecologically distinct groups for wildlife management that differ in the environmental conditions they experience across seasons of the annual cycle, which is a key component for understanding and reversing declines of migratory species. Abstract Patterns of migratory
