Tackling Marine Litter—LITTERBASE [PDF]

, 2018
Anthropogenic litter contamination of the oceans is a global problem of growing concern and currently receives strongly increasing attention by policy makers, public authorities, media and the general public. Unlike many other pollutants, marine litter on beaches and its deleterious effects on marine mammals, birds and turtles have attracted much ...

300 Years of Degradation in Wales Estuaries and Coasts

Natural Resources Forum, EarlyView.
ABSTRACT The world's oceans are in a severe state of degradation, yet our understanding of that degradation is often based on changes observed only in the past 20–50 years. This narrow view leads to marine conservation efforts that aim to preserve already degraded ecosystems, shaped by shifted ecological baselines.

Emerging Technologies for Remote Sensing of Floating and Submerged Plastic Litter

Remote Sensing
Most advances in the remote sensing of floating marine plastic litter have been made using passive remote-sensing techniques in the visible (VIS) to short-wave-infrared (SWIR) parts of the electromagnetic spectrum based on the spectral absorption ...

Burrow Persistence and Spatial Distribution of Federally and State‐Protected Gopher Tortoise (Gopherus polyphemus) Populations in Southwest Alabama

Animal Conservation, EarlyView.
The gopher tortoise (Gopherus polyphemus), a keystone species and ecosystem engineer, has declined by ~80% over the past century due to primarily habitat loss. In a 28‐year resurvey of federally protected Mobile County and state‐protected Baldwin County, we found tortoise populations persisted at ~59% and ~31% of sites, respectively, with significant ...

Anticoagulant Rodenticides Contribute to a Decline in an Urban Carnivore

Animal Conservation, EarlyView.
Anticoagulant rodenticides (ARs) have been shown to negatively affect carnivores globally and are closely tied to human activity and development. We examined drivers of annual survival in bobcats persisting on a residentially developed barrier island over 16 years.

Research on Residents’ Policy Preference for Long-and Short-term Treatment of Marine Litter in China

Haiyang Kaifa yu guanli
Controlling marine litter is a critical necessity for the development of a maritime power and a strategic approach to marine ecological civilization. Employing a randomized controlled trial framework, this study constructs different scenarios for long ...

A machine learning-based detection, classification, and quantification of marine litter along the central east coast of India

Frontiers in Marine Science
Globally, the growth of plastic production has increased exponentially from 1.5 million metric tons (Mt) in 1950 to 400.3 Mt in 2022, resulting in a substantial increase of marine litter along the coastal region. Presently, there is a growing interest in

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework

Conservation Biology, EarlyView.
Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

Microplastics in seawater: Recommendations from the Marine Strategy Framework Directive implementation process

Frontiers in Marine Science, 2016
Microplastic litter is a pervasive pollutant present in marine systems across the globe. The legacy of microplastics pollution in the marine environment today may remain for years to come due to the persistence of these materials.
