Content in nine minerals and seven vitamins of rotifers (Brachionus plicatilis) fed commercial diets and two forms of Nannochloropsis oculata

Journal of the World Aquaculture Society
The objective of the present study was to determine the effects of spray‐dried and fresh forms of the microalgae Nannochloropsis oculata and other commonly used commercial diets on vitamin and mineral compositions of rotifer produced under commercial ...

Insights and predictions of Phytoplankton Biomass in Equatorial Pacific using Random Forest Modeling

, 2023
Phytoplankton biomass drivers are integral to our understanding of how climate change will impact the carbon cycle as photosynthesis and carbon sequestration play a crucial role in mitigating climate change. The equatorial Pacific is a region with high

High‐dimensional elementomes outperform CNP models in explaining photosynthetic traits

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Links between plant elementomes (i.e. the concentration of chemical elements in plant tissue) and functional traits have the potential to improve predictions of plant physiological performance and ecosystem processes, and their response to environmental change.

PLANKTON DYNAMICS [PDF]

, 2008
Phytoplankton growth is controlled by the balance between reproduction and mortality. Phytoplankton reproduction is determined by environmental factors (such as temperature and pH) and by essential resources (such as light and nutrients). In my thesis, I

Why don't all birds lay early? Causes and consequences of breeding timing for a long‐lived migratory seabird

Journal of Animal Ecology, EarlyView.
Why don't all birds lay early? Our 16‐year study of Manx shearwater behaviour shows that selection on breeding timing fluctuates among years. We also find that lay dates are influenced by persistent individual differences, variation in non‐breeding duration, and pair synchrony, potentially constraining breeding phenological advancement under ongoing ...

Spatial variations of small phytoplankton contributions in the Northern Bering Sea and the Southern Chukchi Sea

GIScience & Remote Sensing, 2019
Phytoplankton size classes (hereafter, PSCs) were derived from satellite ocean color data using a present phytoplankton abundance-based optical algorithm in the northern Bering and southern Chukchi Seas to characterize the spatial and seasonal variations

Temporal and spatial variations in phytoplankton productivity in surface waters of a warm-temperate, monomictic lake in New Zealand [PDF]

, 2010
Surface phytoplankton productivity measurements were carried out in morphologically complex Lake Rotoiti with the objective of defining variations between sites and seasons, and the dominant environmental drivers of these variations.

Inhibin βB Mediates Oligotrophic Adaptation via Regulating Muscle Satellite Cell Proliferation and Differentiation in Schizopygopsis younghusbandi

Integrative Zoology, EarlyView.
① Nutrient deficiency upregulates inhibin βB, activating SMAD signaling to promote p21. Increased p21 inhibits mcm2/mcm4/mcm5 and cyclin E2, inducing G1‐phase arrest, slowing growth, and reducing energy consumption. ② Inhibin βB also upregulates pdgf‐c, which induces α‐SMA, leading to muscle satellite cell fibrosis.

Estimating absolute DNA abundance from replicated metabarcoding

Methods in Ecology and Evolution, EarlyView.
Abstract Datasets derived from mixed‐template DNA amplification and sequencing (‘metabarcoding’) are common in environmental DNA (eDNA), microbiome or microbial ecology analyses. Such metabarcoding data have been broadly used to inform estimates of biodiversity, distribution and abundance across a wide range of species and habitats.

A new approach for detecting phenological change using Time of Emergence (ToE) methodology

Methods in Ecology and Evolution, EarlyView.
Abstract Many species are responding to environmental change by shifting the timings of phenological events such as migration or reproduction. These shifts are typically reported as rates of change, which do not indicate when such shifts transcend their original states, nor consider whether species experience novel environmental conditions or ...
