Integrating ecological feedbacks across scales and levels of organization

Ecography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Does rock type account for variation in mussel attachment strength? A test with Brachidontes rodriguezii in the southwestern Atlantic [PDF]

, 2018
Mussel attachment strength varies in space and time, frequently in association with variations in wave exposure. Yet, it remains uninvestigated whether different rock types can contribute to variation in mussel attachment. Here we compared the attachment

Colour Polymorphism in Coconut Crabs Is Under Relaxed Selection From Conspecifics?

Ethology, EarlyView.
Coconut crabs are either red or blue irrespective of age or sex, are nocturnal and have very few predators. This experimental study shows that they do not use conspecific's colour but do use relative size to settle competitive interactions over food in the wild.

Global Analysis of Shallow Underwater Fish Observation Research: 70 Years of Progress, Persistent Geographic Biases and a Path Forward

Fish and Fisheries, EarlyView.
ABSTRACT Marine ecosystems are increasingly threatened by overfishing, pollution, coastal development and climate change, underscoring the need for long‐term, representative information on key fish populations and habitats to inform management and policy.

Characterisation of a phylogenetically distinct PL25 family ulvan lyase from a seaweed biomass enriched metagenome

The FEBS Journal, EarlyView.
Ulvan is a polysaccharide available from green seaweed with beneficial properties for various applications. The full potential of ulvan requires enzymatic degradation of the polymer, thus producing ulvan oligosaccharides. This study expands the armoury of characterised ulvan lyases.

Stages of sedimentary infilling in a hypertidal bay using a combination of sedimentological, morphological and dynamic criteria (Bay of Somme, France)

Journal of Maps, 2017
In the context of rising sea level, many estuaries and bays show an overall trend to sedimentary infilling. Among these coastal environments, the Bay of Somme is a hypertidal tide and wave-dominated estuary, filled in by marine sands, with a superficy of
