Abstract

Environmental controls and anthropogenic impacts on deep-sea sponge grounds in the Faroe-Shetland Channel, NE Atlantic: the importance of considering spatial scale to distinguish drivers of change

Highlights

  • Ecological communities and processes such as recruitment or dispersal vary over temporal and spatial scales (Wiens, 1989)

  • Changing sampling scale when analysing the same ecological assemblage can lead to drastically different findings (Nogues-Bravo et al, 2008) and spatial analysis has been increasingly used in ecology in recent decades (Dale and Fortin, 2014)

  • Overall megafauna composition recorded in this study are in accordance with previous studies (Axelsson, 2003; Howell et al, 2007; Jones et al, 2007a; Kazanidis et al, 2019)

Summary

Introduction

Ecological communities and processes such as recruitment or dispersal vary over temporal and spatial scales (Wiens, 1989). Changing sampling scale when analysing the same ecological assemblage can lead to drastically different findings (Nogues-Bravo et al, 2008) and spatial analysis has been increasingly used in ecology in recent decades (Dale and Fortin, 2014). This is important with recent fast temporal changes observed in ecosystems as a consequence of human activities and global climatic change (Halpern et al, 2008).
