Uptake and accumulation of metals in Spartina alterniflora salt marshes from a South American estuary [PDF]

, 2019
Salt marshes are capable of reducing metal pollution in coastal waters, but this capacity is highly dependent on the metal, the physico-chemical characteristics of the sediment, the plant species, the production of biomass, the time of the year, etc. The

Sponges are celebrated heterotrophs but also key primary producers on changing coral reefs

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Trophic interactions and nutrient cycling lay at the heart of ecosystem health and biodiversity. In recent years, our understanding of these drivers has been repeatedly challenged by rapid and unanticipated climatic effects, combined with an increasing awareness that ...

Global blue carbon losses from salt marshes exceed restoration gains

Nature Communications
Salt marsh soil organic carbon (SOC) is a key blue carbon pool affected by both disturbance and restoration; yet its long-term global dynamics remains poorly understood.

Impact of cutting and sheep grazing on ground-active spiders and carabids in intertidal salt marshes (Western France) [PDF]

Animal Biodiversity and Conservation, 2007
The aims of this study were to characterize spider (Araneae) and ground beetle (Coleoptera Carabidae) communities in managed (cutting and sheep grazing) and non-managed salt marshes and to assess the efficiency of management regimes in these particular ...

The effect of flight line spacing on radioactivity inventory and spatial feature characteristics of airborne gamma-ray spectrometry data [PDF]

, 2008
Airborne Gamma Spectrometry (AGS) is well suited to the mapping of radioactivity in the environment. Flight parameters (e.g. speed and line spacing) directly affect the rate of area coverage, cost, and data quality of any survey.

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.

Managing the Threat of Subsidized Predators for a Threatened Shorebird

Animal Conservation, EarlyView.
Subsidized predators—native predators that have become more common due to human activities—challenge the persistence of many at‐risk prey species and require creative solutions beyond lethal predator control. In an 8‐year study, we placed small wire cages over western snowy plover nests that allow passage of plovers, but not their predators, and ...

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.

Differential introgression and the maintenance of species boundaries in an advanced generation avian hybrid zone [PDF]

, 2016
Background: Evolutionary processes, including selection and differential fitness, shape the introgression of genetic material across a hybrid zone, resulting in the exchange of some genes but not others.

Extraction of tidal channel networks from airborne scanning laser altimetry and aerial photography [PDF]

, 2003
The study of the morphodynamics of tidal channel networks is important because of their role in tidal propagation and the evolution of salt-marshes and tidal flats. Channel dimensions range from tens of metres wide and metres deep near the low water mark
