Oligotrichids and choreotrichids are ciliate taxa contributing to the multi-step microbial food
web and episodically dominating the marine microzooplankton. The global diversity and …

Pesticides are frequently applied to agricultural activities to improve harvest, in terms of yield
and product quality. Useful tools for ecotoxicological studies of marine ecosystems are …

Spatial variation in species composition is one of the most fundamental and conspicuous
features of the natural world. Measures of compositional differentiation and similarity …

Our knowledge on microbial biogeography depends on the way we define and study
diversity. In contrast to most microbes, some protist lineages have conspicuous structures …

Tintinnid ciliates are suitable models to study the diversity and biogeography of microbial
plankton. In addition to morphological data accumulated over two centuries, most known …

Zooplankton diversity and biogeography have been based on morphological identifications
for over 200 years but are increasingly being studied by DNA sequences. To better integrate …

The classical paradigm about marine N2 fixation establishes that this process is mainly
constrained to nitrogen-poor tropical and subtropical regions, and sustained by the colonial …

Reproduction and recruitment of benthic invertebrates are influenced by the climate and by
the ecological structure of marine ecosystems, along with local anthropogenic pressures …

Abstract Changes in the tintinnid community were studied in the neritic area of the middle
Adriatic Sea from January 1998 until November 1999. Variability in tintinnid abundance …

Marine environmental disturbance can be assessed directly from physical and chemical
parameters, or indirectly by the study of indicator species. In this study, an integrated …
