Xenophyophores are a group of exclusively deep-sea agglutinating rhizarian protozoans, at least some of which are foraminifera. They are an important constituent of the deep-sea megafauna that are sometimes found in sufficient abundance to act as a significant source of habitat structure for meiofaunal and macrofaunal organisms.

- [Fish in cold-water coral habitats](https://anddavies.co.uk/marine-ecology/597/) - Cold-water corals (CWC) can form complex three-dimensional structures that can support a diverse macro- and megafaunal community. These reef structures provide important biogenic habitats that can act as refuge, feeding, spawning and nursery areas for fish. However, quantitative data assessing the linkage between CWC and fish are scarce. The North Atlantic Ocean is a key region in the worldwide distribution of Lophelia pertusa, which is thought to be the most widespread frame-work forming cold-water coral species in the world. This study examined the relationship between fish and CWC reefs in the northeast Atlantic Ocean by means of video and remotely sensed data from three different CWC communities (Rockall Bank, Hatton Bank and the Belgica Mound Province).

Davies, J. Murray Roberts, Jason Hall-Spencer Published in Biological Conservation (2007) Human activity in the deep sea is extending ever deeper, with recent research showing that this environment is more sensitive to human and natural impacts than previously thought. Some deep-water fish stocks have collapsed and fishing methods such as bottom trawling have

Davies, Mark P. Johnson, Christine A. Maggs Published in Marine Ecology-Progress Series (2007) The role of limpet grazing in preventing the development of algal canopies is a recurrent theme in intertidal ecology. Less is known about interactions of limpets with the long-term dynamics of established canopies. Aerial photographs indicate that intertidal canopy cover

Davies and Mark P. Johnson Published in Estuarine, Coastal and Shelf Science (2006) Both climate change and the North Atlantic Oscillation (NAO) may influence coastal systems by altering wave exposure. The effects of such climatic forcing are often coherent over relatively large geographic areas. Temporal trends in wave exposure at any particular shore

This is all thanks to a couple of settings that I managed to get working
- [Flight testing the HexaXL](https://anddavies.co.uk/marine-ecology/flight-testing-the-hexaxl/) - Well, I've been flying the HexaXL for a few weeks with very basic manoeuvres. This week I finally added my compact camera to the camera gimbal to collect some video footage. It is certainly much more challenging than I would have ever expected. Much more practice required! Check out the video: httpv://www.youtube.com/watch?v=9kICtEBJ3kk

My Mikrokopter Hexa XL is complete and is nearing flight ready. With such an investment both in time and money, I'm understandably nervous about flying it for the first time. The Hexa was bought to support an ongoing project of mine,
