When do citizen scientists record biodiversity? Non‐random temporal patterns of recording effort and associated factors

People and Nature, Volume 7, Issue 4, Page 860-870, April 2025.
Abstract Citizen science data are increasingly used for ecological research, biodiversity conservation and monitoring. However, these data often present significant analytical challenges due to uneven recording efforts by citizen scientists. Biases caused by intra‐annual differences in levels of recording activity can be particularly severe, hindering ...

Association of maternal body mass index with hemodynamic and vascular alterations at 35–37 weeks' gestation

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 3, Page 303-310, March 2025.
ABSTRACT Objective Globally, one in four pregnant women is classified as overweight or obese, based on their prepregnancy body mass index (BMI). Obese pregnant women are at increased risk of adverse pregnancy outcomes and long‐term cardiovascular disease that occurs earlier in life.

Land use history and landscape forest cover determine tropical forest recovery

Journal of Applied Ecology, Volume 61, Issue 10, Page 2365-2381, October 2024.
Both a higher land use intensity and fragmented forest landscape decreases the speed of forest recovery, indicating that human actions and landscape transformation shape the course of succession. Restoration in fragmented forest landscapes through natural regeneration is more suitable in areas with low previous land use intensity, higher forest ...

Scouts vs. usurpers: alternative foraging strategies facilitate coexistence between neotropical Cathartid vultures

Ibis, Volume 166, Issue 4, Page 1368-1383, October 2024.
Understanding how diverse assemblages of scavengers can coexist on shared ecological resources is a fundamental challenge in community ecology. However, current approaches typically focus on behaviour at carcass provisioning sites, missing how important differences in movement behaviour and foraging strategies can facilitate sympatric species ...

Using artificial neural networks and citizen science data to assess jellyfish presence along coastal areas

Journal of Applied Ecology, Volume 61, Issue 9, Page 2244-2257, September 2024.
This research provides actionable recommendations for beach management. The implementation of continuous monitoring of sea surface temperature and wind conditions will enable more accurate predictions of jellyfish distribution. Adaptive management strategies that respond dynamically to environmental data will help mitigate the impact of jellyfish ...
