Gas exchange and pulmonary stress variations during SCUBA and breath‐hold diving in open seawater

The Journal of Physiology, EarlyView.
Abstract figure legend Healthy, trained divers were studied before, during and after diving in open seawater with different techniques. SCUBA divers (diving to 15 or 40 m with air; cycling at depth) and breath‐hold divers (BHDs; sled‐assisted dives to 15, 25 or 40 m) underwent underwater and surface arterial blood gas (ABG) sampling.

Habitat Suitability for a Unique, Fully Marine American Manatee (Trichechus manatus) Population Primarily Depends on Presence of Submarine Freshwater Springs

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The American manatee (Trichechus manatus) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater.

American manatees adjust their diet composition and trophic niche breadth across different coastal regions

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Marine mammals can exhibit high plasticity in foraging strategies, but how such plasticity is driven by environmental conditions is poorly understood. The American manatee (Trichechus manatus), a large, endangered herbivore, inhabits marine, estuarine, and freshwater environments.

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

People and Nature, Volume 8, Issue 5, Page 1155-1171, May 2026.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

Remote Text‐Supplemented Audiobook Intervention Supports Children's Explicit and Incidental Vocabulary Learning

Developmental Science, Volume 29, Issue 3, May 2026.
ABSTRACT Vocabulary knowledge is foundational to educational success, but significant gaps exist between students with reading disabilities or those from disadvantaged backgrounds and their peers. These gaps have cascading effects, as children with lower vocabulary knowledge are less likely to acquire new words through independent reading and are less ...

A multi-decadal aerial survey reveals patterns in manatee abundance and response to seagrass die-offs

Frontiers in Marine Science
Florida manatees (Trichechus manatus latirostris) are challenged by human alteration of landscapes and waterways. Coastal eutrophication has increased the frequency and intensity of Indian River Lagoon (IRL) algal blooms, promoting seagrass die-offs in ...

FROM THERE TO HERE: USING PHOTOGRAPHY TO EXPLORE PERSPECTIVES OF RESETTLED REFUGEE YOUTH

International Journal of Child, Youth & Family Studies, 2012
Because refugee numbers are much smaller than those of other immigrant populations in the United States, researchers frequently group refugees with other immigrants in their studies.
