MODIS: Moderate Resolution Imaging Spectrometer [PDF]

open access: yes, 2002
This brochure describes the Moderate Resolution Imaging Spectrometer (MODIS) instrument on NASA's Terra satellite. The first NASA Earth Observing System (EOS) satellite, Terra, was launched on December 18, 1999, carrying five remote sensors.

Differential effects of Daphnia genotype composition on spatial environmental heterogeneity in experimental metacommunities

open access: yesLimnology and Oceanography, EarlyView.
Abstract Spatial environmental heterogeneity is an important driver of aquatic biodiversity. Ecological and evolutionary theory often consider spatial heterogeneity as being driven by exogenous factors, yet heterogeneity can also be generated and modified by organisms.

How self-regulation, the storage effect and their interaction contribute to coexistence in stochastic and seasonal environments [PDF]

open access: yes, 2019
Explaining coexistence in species-rich communities of primary producers remains a challenge for ecologists because of their likely competition for shared resources.

Nutrient inversion but not warming drive changes in periphyton biomass and composition in shallow lake mesocosms

open access: yesLimnology and Oceanography, EarlyView.
Abstract Periphyton plays an important functional role in shallow lakes and is sensitive to variation in nutrient availability and global warming. Understanding the responses of periphyton to changes in nutrient availability in contrasting warming scenarios can contribute to the development of more efficient techniques for the restoration of lakes in a

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

open access: yesGIScience & 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

Water quality evaluation in Mediterranean Lagoons using the Multimetric Phytoplankton Index (MPI): study cases from Sardinia [PDF]

open access: yes, 2013
1 - Water quality in four Sardinian lagoons (western Mediterranean Sea) was assessed using the Multimetric Phytoplankton Index (MPI), which is consistent with the EU Water Framework Directive.

Saharan dust deposition may affect phytoplankton growth in the mediterranean sea at ecological time scales [PDF]

open access: yes, 2014
The surface waters of the Mediterranean Sea are extremely poor in the nutrients necessary for plankton growth. At the same time, the Mediterranean Sea borders with the largest and most active desert areas in the world and the atmosphere over the basin is

Trophic strategies of freshwater nanoflagellates under variable run‐off scenarios

open access: yesLimnology and Oceanography, EarlyView.
Abstract Terrestrial run‐off is increasing in temperate lakes due to climate change and can lead to loading of colored dissolved organic matter (cDOM) and nutrients, thus reducing light availability and increasing carbon, nitrogen, and phosphorus. Run‐off events are highly irregular, resulting in temporal resource variability that may determine the ...

Insight into diversity change, variability and co-occurrence patterns of phytoplankton assemblage in headwater streams: a study of the Xijiang River basin, South China

open access: yesFrontiers in Microbiology
Phytoplankton has been used as a paradigm for studies of coexistence of species since the publication of the “paradox of the plankton.” Although there are a wealth of studies about phytoplankton assemblages of lakes, reservoirs and rivers, our knowledge ...

The influence of physico-chemical parameters on phytoplankton distribution in a head water stream of Garhwal Himalayas: A case study

open access: yesEgyptian Journal of Aquatic Research, 2016
Physico-chemical parameters play a major role in determining the density, diversity and occurrence of phytoplankton in a headwater stream. The present study was conducted to assess the relationship between physico-chemical parameters and phytoplankton ...
