The application of artificial floating islands in saline environments

Artificial Floating Islands (AFIs) have primarily been used in freshwater habitats such as reservoirs, ponds and river systems for water quality improvement and habitat creation for breeding birds. To assess the potential application of AFIs in marine environments, this comparative study focuses on both the floral species suitable for island installation and the fauna associated with the islands including birds, fish and invertebrate populations. By addressing gaps in current research on artificial habitat creation, this study aims to support future ecosystem enhancement programs that seek to mitigate the loss of coastal habitats via coastal hardening.

Remote methods for the assessment of coastal biodiversity interacting with marine renewable developments

The rapid development of new technologies in the marine renewable energy fields creates a series of challenges in the management of marine coastal resources. Traditional methodologies for assessing habitats, fish assemblages and marine mammals are no longer appropriate as they are often not suitable for use around hard structure associated with marine renewable developments and any potentially sensitive habitats and species found in the area. The use of traditional technologies for assessing habitats and motile fauna creates uncertainly in the Environmental Impact Assessment (EIA) process potentially leading to poor decision making and opening up such decisions to future legal challenge. This talk will introduce different novel methods for the use of baited underwater camera systems, for assessing flora and fauna around areas with the potential for marine renewable structures and their associated marine environments.

Native or introduced by humans? Using species distribution modelling to analyze Sweet chestnut dynamics in Western Europe

My main research topics are a mixture of landscape and forest ecology, and I find interesting to analyze how the forests and their ecosystem services area distributed, and how we can use this information on landscape planning and natural resources management. In this sense, Sweet Chestnut (Castanea sativa: one of the most relevant forests trees of my home country region Asturias, NW Spain) is often classified as a “non-native species” and its origin discussed between scientific community, foresters, etc. For this reasons, we use a “species distribution modelling” approach to analyze its suitable areas in Europe since the Last Glacial Maximum until today. We have tried to confirm (or reject) if, as some authors found (based on pollen and genetic data), this tree had (glacial) refugia in Western Europe and can be classified a native species in this area.

Brown trout in the Falkland Islands: ecology, population structure and genetic diversity.

Brown trout (Salmo trutta) were introduced to the Falkland Islands on several occasions during the 1940-50’s, mainly for recreational fishing. Since, there has been a marked decline in the native freshwater fish fauna, which consists of only three species of galaxiid fishes, endemic to the Southern Hemisphere (zebra trout Aplochiton zebra, Aplochiton taeniatus, and the Falklands minnow Galaxias maculatus). Given the threats to the long-term conservation of the native galaxiids, detailed knowledge about the life history, movement ecology of brown trout and their overlap and interactions with the native species is urgently needed.
