The Ultrastructure of the Apical Organ of the Goette's Larvae of the Polyclad Flatworm Stylochus pilidium Indicates Homology Between Polyclad Larvae

open access: yesCell Biology International, EarlyView.
ABSTRACT Polyclad flatworms exhibit both direct and indirect development, with various larval types observed, including Müller's larva, Kato's larva, Goette's larva and Curini‐Galletti's larva. The different larval types are distinguished by shape, number of eyes and number of lobes.

Hydro-plankton characteristics and their relationship with sardine and anchovy distributions on the French shelf of the Bay of Biscay

open access: yesScientia Marina, 2006
The spatial pattern in hydro-plankton and fish distributions and their relationship were analysed based on the spring 2000 fisheries acoustic survey. The importance of this survey was that it was a multi-disciplinary platform which collected an extensive

The effect of intermittent upwelling events on plankton blooms [PDF]

open access: yesarXiv, 2019
In the marine environment biological processes are strongly affected by oceanic currents, particularly by eddies (vortices) formed by the hydrodynamic flow field. Employing a kinematic flow field coupled to a population dynamical model for plankton growth, we study the impact of an intermittent upwelling of nutrients on triggering harmful algal blooms (

Simulating the onset and spread of anoxic conditions during Cretaceous OAE2 [PDF]

open access: yes, 2010
A new model of the global atmosphere-ocean-continent-mantle system was set-up to investigate the triggering of the Oceanic Anoxic Event OAE2 through volcanic degassing processes at large igneous provinces (LIPs).

Laser‐Induced Graphene for Early Disease Detection: A Review

open access: yesChemElectroChem, Volume 12, Issue 6, March 15, 2025.
Laser‐induced graphene (LIG) has emerged as a superior alternative to conventionally synthesized graphene due to its flexibility, cost‐effectiveness, scalability, high conductivity, and the ability to customize its properties for various applications. This review highlights LIG′s transformative potential in electrochemical biosensing, focusing on early

Microbial Electrosynthesis for Sustainable Polyhydroxybutyrate Production from CO2 Using Bismuth Nanoparticles

open access: yesChemElectroChem, EarlyView.
Electrochemical CO2 reduction using a Bi‐based electrode generates formate as the sole carbon source for Cupriavidus necator to synthesize polyhydroxybutyrate (PHB). Two configurations are evaluated: the integrated system, performing fermentation in the same reactor post‐electrolysis, while the drop‐in system decouples both steps.

An assessment of plankton populations, toxic cyanobacteria, and potential impact of introduced marine alewife (Alosa pseudoharengus) in Pawtuckaway Lake, New Hampshire [PDF]

open access: yes, 2006
A field study was conducted during the summer, 2005 to evaluate the lake water quality and planktonic communities in Pawtuckaway Lake, NH. Of special concern was the condition of the plankton populations since the lake had been subjected to introductions

Stochastic population dynamics in turbulent fields

open access: yes, 2007
The behavior of interacting populations typically displays irregular temporal and spatial patterns that are difficult to reconcile with an underlying deterministic dynamics.

Late Pleistocene to Holocene sedimentation in the Great Blue Hole (Lighthouse Reef, Belize): Results from a 30 m long core

open access: yesThe Depositional Record, EarlyView.
A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes

From waste to resource: Effects of digested rotten potato supernatant on the growth, total biomass and nutrient composition of Chlorella vulgaris

open access: yesHeliyon
A study was carried out to evaluate the growth performance of Chlorella vulgaris, a green microalga, in three different concentrations of digested rotten potato supernatant (DRPS) for 16 days. C.
