The utilization of polychaetes in descriptive ecology is reviewed in the light of recent
research especially concerning the biota hard bottom environments. Polychaetes, often …

Cystoseira species are some of the most important marine ecosystem-engineers, forming
extended canopies comparable to land forests. Such forests are sensitive to human …

Rocky shores occur at the interface of the land and sea. Typically they are open ecosystems,
with steep environmental gradients. Their accessibility to man has rendered them …

Photographic quadrat sampling is commonly used for the study of sessile benthic
communities. However, photoquadrat data handling is fragmented into several processing …

Increasing evidence indicates that spatial and temporal patterns in ecological systems are
not independent of the scale of measurement. In this study we used a hierarchical sampling …

Background Predicting and abating the loss of natural habitats present a huge challenge in
science, conservation and management. Algal forests are globally threatened by loss and …

This paper highlights the poor esteem in which taxonomy, as autonomous science, is held
and the relative implications of this for conservation biology. 2. In recent times, taxonomy at …

Summary 1 We investigated the effects of changes in taxonomic resolution on analyses of
patterns of multivariate variation at different spatial scales for the highly diverse fauna …

Tourism has long been considered as a 'clean industry'with almost no negative effects on
the environment. This study demonstrated, in two different coastal systems (Mediterranean …
