Effects of fishing and protection on Brazilian reef fishes [PDF]

Biological Conservation, 2006
The vast Brazilian coast harbors unique and diverse reef fish communities. Unfortunately, relatively little is known about the impact of fishing on these fish species, and few management or conservation efforts are being made to protect them. Here, we examine the effect of different levels of protection on the composition, abundance, and size structure

Ocean Governance and Marine Conservation: Institutional Work as a Lever for Ocean Sustainability

Environmental Policy and Governance, EarlyView.
ABSTRACT Ocean governance presents one of the most complex environmental policy challenges of our time, requiring coordinated action across multiple scales, sectors and stakeholder groups. This paper applies institutional work theory to systematically examine how actors create, maintain and disrupt the governance arrangements underpinning ocean ...

Regional Endothermy in a Coral Reef Fish?

PLoS ONE, 2012
Although a few pelagic species exhibit regional endothermy, most fish are regarded as ectotherms. However, we document significant regional endothermy in a benthic reef fish. Individual steephead parrotfish, Chlorurus microrhinos (Labridae, formerly Scaridae) were tagged and their internal temperatures were monitored for a 24 h period using active ...

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

FlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Association of novel intra‐cesarean post‐placental intrauterine device insertion techniques, and early ultrasound, with expulsion rates and strings visibility: A prospective exploratory study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To assess an innovative technique of intra‐cesarean post‐placental insertion of the Copper T380A IUD (CPPIUD), and explore the role of predischarge ultrasound with replacement of low‐lying IUDs. Methods We conducted a prospective observational study at Princess Marina Hospital, Gaborone, Botswana, from May 31, 2023, to April 3, 2024.

Mapping the subgingival HerBiome and HisBiome over the human healthspan

Journal of Periodontology, EarlyView.
Abstract Background Understanding the intricate relationship between sex, age, and the oral microbiome is crucial for deciphering the onset and progression of numerous age‐related oral and systemic diseases. Methods Subgingival plaque was collected from 781 periodontally and systemically healthy females and 160 males spanning 0 to 80 years.

Check list of the marine commercial and reef fishes of Belitung Timur, Bangka Belitung Islands, Indonesia

Aceh Journal of Animal Science, 2018
Marine fish community is very sensitive to environmental changes. So the number of species, abundance, and biodiversity index can be used as a reference to assess the quality of the aquatic environment.

Vulnerability to fishing in reef fishes that aggregate

, 2015
Many species of coral reef fish form aggregations at predictable times and locations for the purpose of spawning. Targeted fishing of spawning aggregations can result in loss of aggregations, rapid population depletion and fishery collapses. However, there are also examples of spawning aggregation fisheries that have persisted for decades, including ...

Sodium sulfite can reliably induce chemical hypoxia without toxic effects in the model sea anemone species, Exaiptasia diaphana

Limnology and Oceanography: Methods, EarlyView.
Abstract Climate change is accelerating the deoxygenation of aquatic ecosystems, so understanding its effects on biological processes is increasingly critical. An emerging method for inducing hypoxia during experimentation utilizes sodium sulfite (SSI) to scavenge oxygen; however, it remains unclear if hypoxia‐inducing concentrations of SSI are toxic ...

Seagrass species diversity in Tanzania based on morphological and molecular data

Nordic Journal of Botany, EarlyView.
Seagrass diversity along the Tanzanian coast has been documented mainly through morphology, with limited molecular reference data available for Tanzania and the wider Western Indian Ocean. This study combined morphological identification with nuclear ribosomal internal transcribed spacer (ITS) and plastid ribulose‐1,5‐bisphosphate carboxylase/oxygenase
