Analysis of reef fish community structure as a basis for identifying potential OECM in the Kilwaru-Kiltay Area, East Seram, Indonesia [PDF]

BIO Web of Conferences
Reef fish communities are widely used as sensitive bioindicators of coral reef ecosystem condition and provide an ecological basis for area- based conservation planning, including Other Effective Area-based Conservation Measures, yet site-specific ...

Evaluation of LiDAR‐based canopy trait estimation in Midwestern row crops

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Stand count, the number of plants per unit ground area, and leaf area index (LAI), the ratio of leaf area to ground area, are critical traits for crop research but are traditionally measured using labor‐intensive methods. While new sensing technologies are being developed, quantifying improvement in measurement efficiency and data quality ...

Comparisons between abundance estimates from underwater visual census and catch-per-unit-effort in a patch reef system [PDF]

Marine Ecology Progress Series, 2012
ABSTRACT: Methods of underwater visual censuses (UVC) and catch-per-unit-effort (CPUE) areboth commonly used to estimate abundance of fish stocks. While each method is subject to certainbiases, in theory they should produce related measures of fish abundance for a specific site at agiven point in time, for species targeted by both methods.

Riparian Amphibian and Reptile Assemblages in Streams Along a Forest Regeneration Gradient in the Ecuadorian Chocó

Biotropica, Volume 58, Issue 6, November 2026.
ABSTRACT While primary forests are declining, regenerating habitats are becoming increasingly common. In fragmented environments, streams may function as corridors between forest remnants for riparian and aquatic species. However, the responses of stream‐associated species to forest regeneration remain understudied.

Assessment of fish diversity in the coastal waters off Nodaedo Island, Tongyeong, Korea using underwater visual census and environmental DNA metabarcoding

Marine Biology, 2022
Abstract Environmental DNA (eDNA) analysis is a promising method to monitor marine biodiversity. Examining the capacity of eDNA to provide accurate biodiversity measures in species-rich ecosystems such as coastal waters is a prerequisite for their application in long-term monitoring.

Assessing responses of reef island seabirds to environmental and anthropogenic drivers

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Insights from three decades of IUCN Red List assessments catalyzing shark, ray, and chimaera conservation

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time.

Length‐Based Spawning Potential Ratio Assessment of Key Species From a Remote Recreational Fishery at Diego Garcia, Indian Ocean

Fisheries Management and Ecology, Volume 33, Issue 5, Page 977-989, October 2026.
ABSTRACT Recreational fisheries in remote regions often operate under limited regulation and data availability, presenting challenges for sustainable management. Diego Garcia, located within the Chagos Marine Protected Area, hosts a unique recreational reef fishery embedded within a highly protected environment. We assessed the stock status of five key

On the reliability of the Autosub autonomous underwater vehicle [PDF]

, 2003
As autonomous underwater vehicles (AUVs) enter operational service an assessment of their reliability is timely. Using the Autosub AUV as an example, several design issues affecting reliability are discussed, followed by an analysis of recorded faults ...
