Cell death in lake phytoplankton communities

Freshwater Biology, 2006
Summary1. The fraction of living and dead phytoplankton cells in seven Florida lakes was assessed by using the cell digestion assay, a non‐staining membrane permeability test. The cell digestion assay is an effective method to analyse cell viability in complex natural phytoplankton communities. 2.

Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

Boreas, EarlyView.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

Phytoplankton Community Composition Retrieval From Space

Phytoplankton community composition (PCCs) - also referred to as functional groups play a key role in ocean biogeochemical cycling, climate regulation, and marine ecosystem dynamics. Accurate quantification of these groups from satellite ocean color data remains challenging due to spectral similarities among phytoplank- ton types and the limitations of

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

Conservation Biology, EarlyView.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Estimating the total mortality of seabirds following a marine heat wave

Conservation Biology, EarlyView.
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

The Community Concept and the Phytoplankton

Marine Ecology Progress Series, 1981
The community concept of terrestrial ecology is examined with particular reference to its application to phytoplankton dlstrlbutlon. I t IS suggested that it is more appropriate to regard phytoplankton distribution as entirely probabilistlc, comparable to a local situation in a tropical rain forest.

Deep Dark Futures: Foresighting Human Impacts on Mesopelagic Ecosystem Services

Fish and Fisheries, EarlyView.
This study uses foresighting to explore four plausible future scenarios of human activity affecting mesopelagic ecosystem services; provisioning, regulating, supporting and cultural. Using participatory scenario development, qualitative network modelling and indicator design, we assess systemic risks and early warning signals linked to harvest, climate
