The estimation of the abundance of ultraplankton [PDF]
British Phycological Journal, 1973 Methods of assessing the amount of ultraplankton in the surface waters of the sea are discussed with particular reference to their use on board ship. A fluorometric technique for the determination of the amount of chlorophyll a produced by the ultraplankton is described, together with a method for estimating the relative amounts of net-plankton and ...

The effects of acoustic misclassification on cetacean species abundance estimation
, 2013 This work was funded through the Natural Environment Research Council and SMRU Ltd.To estimate the density or abundance of a cetacean species using acoustic detection data, it is necessary to correctly identify the species that are detected.

Chemical abundances of LINER galaxies – nitrogen abundance estimations
Monthly Notices of the Royal Astronomical SocietyABSTRACT In this work, we investigated the nitrogen and oxygen abundances in a sample of galaxies with Low Ionization Nuclear Emission Regions (LINERs) in their nucleus. Optical spectroscopic data (3600 – 10 000 Å) of 40 LINERs from the Mapping Nearby Galaxies (MaNGAs) survey were considered.

ASSESSING THE ABUNDANCE OF BASKING SHARKS (CETORHINUS MAXIMUS) IN ATLANTIC CANADIAN WATERS
, 2022 The Atlantic Canadian population of basking sharks (Cetorhinus maximus) is designated Special Concern by COSEWIC. Little is known about their population size or life history, though they are considered to have long life histories and be inherently ...

Ecology and Evolution, 2020 Close‐kin mark–recapture (CKMR) is a method for estimating abundance and vital rates from kinship relationships observed in genetic samples. CKMR inference only requires animals to be sampled once (e.g., lethally), potentially widening the scope of ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...
