Reef fish functional groups show variable declines due to deforestation-driven sedimentation, while flexible harvesting mitigates this damage

Russell Anderson Milne, Madhur Anand, Chris T. Bauch

Published: 2024-01-22
Subjects: Dynamic Systems, Natural Resources and Conservation, Terrestrial and Aquatic Ecology

Sedimentation is a major coral reef stressor, with effects including suppressing algae consumption by herbivorous fish. This puts pressure on reef fish populations and the fisheries that harvest them. Deforestation causes much sedimentation on reefs, and is an ongoing concern in Pacific island states. Although ecosystem processes like deforestation and fish population dynamics are usually far [...]

Deadwood represents a significant carbon pool in forests and savannas. Although previous research has focused mainly on forests, we synthesise deadwood studies across all ecosystems with woody vegetation. Storage and release of carbon from deadwood is controlled by interacting decomposition drivers including biotic consumers (animals, microbes) and abiotic factors (water, fire, sunlight, [...]

Switching to bioplastics may exacerbate ingestion of lost and discarded fishing gear by marine invertebrates

Sandra Powell, Benjamin Mos

Published: 2024-01-09
Subjects: Animal Experimentation and Research, Biology, Environmental Health Life Sciences, Life Sciences, Marine Biology, Natural Resources and Conservation, Sustainability

Bioplastics are argued to be more environmentally sustainable than conventional plastics. Yet, little is known about how bioplastics degrade in marine environments or their likelihood of being ingested by animals. We measured changes in the weight of biodegradable, semi-biodegradable, and non-biodegradable fishing gears (soft plastic lures, SPLs) in or out of seawater over 14 days. We then [...]

Leveraging surf breaks to expand conservation of carbon-dense coastal ecosystems

Jacob J Bukoski, Scott R Atkinson, Marissa Anne S. Miller, et al.

Published: 2023-10-24
Subjects: Forest Management, Natural Resources and Conservation, Other Forestry and Forest Sciences

Surf breaks are increasingly recognized as socio-environmental phenomena that provide opportunities for biodiversity conservation and sustained benefits for local communities. Here, we examine an additional benefit from conserving surf breaks—their coincidence with carbon dense coastal ecosystems. Using global spatial datasets of irrecoverable carbon (defined as carbon stocks that, if lost today, [...]

Landscape changes in the “valli da pesca” of the Venice lagoon and possible effects on the Ecosystem Services supply

Alice Stocco, Lorenzo Duprè, Fabio Pranovi

Published: 2023-06-21
Subjects: Environmental Monitoring, Environmental Sciences, Environmental Studies, Natural Resources and Conservation, Nature and Society Relations, Other Environmental Sciences, Remote Sensing, Sustainability, Terrestrial and Aquatic Ecology

Coastal lagoons have long been subject to continuous changes caused by mutual interactions with human activities. Monitoring such changes becomes critical, particularly when modifications in landscape and land cover classes can affect their capacity to ensure Ecosystem Services (ESs). In the Venice lagoon, some confined areas called “valli da pesca” supply provisioning ESs, namely aquaculture and [...]

Community-based conservation and restoration in coastal wetlands: A review

Alex C Moore, Sumant Kumble

Published: 2023-06-19
Subjects: Natural Resources and Conservation, Natural Resources Management and Policy

Research has shown that conservation and restoration efforts that engage local communities are more successful at meeting stated goals than those that are externally controlled. Such participatory management approaches have been increasingly applied in coastal wetland ecosystems, yet our collective understanding of the scope of methods applied and outcomes observed in these efforts is limited. In [...]

Emerging opportunities for wildlife with sustainable autonomous transportation

Inês Silva, Justin M. Calabrese

Published: 2021-09-29
Subjects: Ecology and Evolutionary Biology, Environmental Sciences, Life Sciences, Natural Resources and Conservation, Physical Sciences and Mathematics, Sustainability

Autonomous vehicles (AV) are expected to play a key role in the future of transportation, and to introduce a disruptive yet potentially beneficial change for wildlife-vehicle interactions. How-ever, this assumption has not been critically examined, and reducing the number of wildlife-vehicle collisions (WVCs) may be beyond current technological capabilities. Here, we introduce a new conceptual [...]

Drivers of the live pet trade: the role of species traits, socioeconomic attributes and regulatory systems

Adam Toomes, Pablo García‐Díaz, Oliver C. Stringham, et al.

Published: 2021-08-27
Subjects: Environmental Sciences, Natural Resources and Conservation, Physical Sciences and Mathematics

The live pet trade is a major driver of both biodiversity loss and the introduction of invasive alien species. Building a comprehensive understanding of the pet trade would improve prediction of conservation and biosecurity threats, with the aim to prevent further negative impacts. We used South Australia’s native wildlife permit reporting system as a data-rich example of a live vertebrate pet [...]
