Sustained plankton blooms under open chaotic flows [PDF]

open access: yesEcological Complexity 1, 253 (2004), 2003
We consider a predator-prey model of planktonic population dynamics, of excitable character, living in an open and chaotic fluid flow, i.e., a state of fluid motion in which fluid trajectories are unbounded but a chaotic region exists that is restricted to a localized area. Despite that excitability is a transient phenomenon and that fluid trajectories

Assessment of the water quality of ten Waikato lakes based on zooplankton community composition. CBER Contract Report No. 60 [PDF]

open access: yes, 2007
Zooplankton communities were documented from ten Waikato lakes from net haul samples collected in late 2006 and from species hatched from diapausing eggs in sediments collected in early 2007.

The Fragility of Plankton

open access: yes
When there is a natural disaster at sea, such as the Exxon Valdez in Alaska (1989) or the Prestige in the NW Spanish coast (2002), we all immediately worry about seabirds, turtles, and dolphins and how the disaster will affect fisheries. On television, we are flooded with images of black birds, covered in oil, and dead fish on beaches.

The Plankton of the Bay of Biscay [PDF]

open access: yesNature, 1900
WITH the valuable assistance of Mr. L. A. Borradaile, of Selwyn College, Cambridge, I have just completed a series of observations on the plankton of the Bay of Biscay, extending over about three weeks, by means of opening and closing nets as well as ordinary tow-nets.

Assessment of Factors Contributing to Infection Severity and High Levels of Drug Resistance in Clinical Enterococcus Isolates

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
E. faecalis was the predominant species (60.7%). Moreover, 39.3% of the isolates were identified as VRE with an MIC > 32 μg/mL, and the vanA gene was detected in 35.7% of the isolates. High‐level resistance to gentamicin and streptomycin was observed in 60.7% and 50% of the isolates, respectively.

The Effects of Lagrangian vs. Population Dynamics on Plankton Patchiness Generation [PDF]

open access: yesarXiv, 2006
The relative importance of Lagrangian and population dynamics on spatial pattern formation in the distribution of plankton near the ocean's surface is investigated. Phytoplankton and zooplankton are treated as biologically interacting tracers that are passively advected by a divergence-free two-dimensional nonsteady velocity field.

Validation and use of the dead‐end ultrafiltration method for the capture and recovery of Shiga toxin‐producing Escherichia coli from surface water

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Root cause analysis following microbial water contamination events typically relies upon the collection of large sample volumes. Dead‐end ultrafiltration (DEUF) is an efficient method for sampling and transporting up to 100 L of water from field environments. A single‐lab validation (SLV) using DEUF to recover Shiga toxin‐producing Escherichia

Exploring the nutritional potential of Monoraphidium littorale and enriched copepods as first feeds for rearing Nile tilapia (Oreochromis niloticus) larvae

open access: yesHeliyon
One of the challenges in the aquaculture industry is providing nutritionally balanced and environmentally sustainable live food for fish larvae. Therefore, the rearing techniques of fish larvae with preferred starter food should be given importance for ...
