Global analysis of seagrass restoration

In this post Marieke van Katwijk discusses her recent paper ‘Global analysis of seagrass restoration: the importance of large‐scale planting’ Have you seen a lot of your restorations fail? Not immediately… but in the end? Repeatedly? Could you not find a consistent environmental correlation to explain it, nor a technique to overcome it? It happened to me. I must admit I felt stupid. I am … Continue reading Global analysis of seagrass restoration

Managing invasive species in a warming Arctic

In this post Associate Editor Joseph Bennett discusses a paper he recently handled by Chris Ware and colleagues ‘Biological introduction risks from shipping in a warming Arctic’ It is well known that the Arctic is one of the most vulnerable regions to the impacts of climate change (IPCC 2014). Climate change will not only have direct impacts, it will also magnify the effects of existing … Continue reading Managing invasive species in a warming Arctic

Ecological considerations for an urban marine environment

In this post Filippo Ferrario discusses his recent paper ‘The overlooked role of biotic factors in controlling the ecological performance of artificial marine habitats’ Summer is going to be over soon and many of us have spent the vacation enjoying sea beaches, practising aquatic sports or looking for a pristine marine landscape, where to hike or a wonderful sunset to cherish. Did you realize how … Continue reading Ecological considerations for an urban marine environment

Helping Hawaiian spinner dolphins rest

In this post Julian Tyne discusses his paper ‘The importance of spinner dolphin (Stenella longirostris) resting habitat: implications for management’ Coastal dolphin populations are exposed to non-consumptive human activities that can pose conservation challenges. Consequently, effective management strategies, using rigorous scientific assessments of exposed populations and their habitats, are needed to mitigate potential negative impacts of these activities. Key habitats may function as critical for … Continue reading Helping Hawaiian spinner dolphins rest

The effects of seals on Scottish cod stock recovery

In this post Robin Cook discusses his recent paper with Steven Holmes and Robert Fryer ‘Grey seal predation impairs recovery of an over-exploited fish stock’ Both seals and humans prey on fish and so potentially compete for the same resource. Such competition is vividly illustrated in the controversy surrounding the effect grey seals have on cod in a number of regions including Canada and the … Continue reading The effects of seals on Scottish cod stock recovery

Can’t see the puffins for the auks? Estimating population size with imperfect species identification

In this post, Alison Johnston (@ali__johnston) talks about her paper published today “Modelling the abundance and distribution of marine birds accounting for uncertain species identification”. Ecological surveys balance the competing goals of data quality and data quantity. We can intensively survey a small area, or cover a larger area with less detail and precision, for example in large-scale citizen science surveys. Recently there has been … Continue reading Can’t see the puffins for the auks? Estimating population size with imperfect species identification

Eyes in the sky see the secrets of the sea

This guest post is by Kylie L. Scales (@KylieScales) on her recent review paper “On the Front Line: frontal zones as priority at-sea conservation areas for mobile marine vertebrates.” The oceans may seem like Earth’s last remaining wilderness, but are in fact teeming with human activity as a result of intense and growing demand for marine resources. Consequently, large marine vertebrates such as seabirds, turtles, … Continue reading Eyes in the sky see the secrets of the sea
