Catchment Productivity Controls Local Species Richness of Hyporheic Invertebrate Communities in Tropical New Caledonia Streams

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
How does the local species richness (LSR) of stream invertebrate communities relate to the terrestrial productivity of the stream catchment? Using generalized linear models and variance partitioning, we quantified the independent and joint effects of local and catchment predictors on LSR of hyporheic invertebrate communities in New Caledonia streams ...

Phytoplankton diversity in coral reefs of Guanahacabibes National Park, Cuba

open access: yesRevista de Investigaciones Marinas
Coral reefs are highly complex and biodiverse ecosystems that are fundamental to ecological balance and socioeconomic development. Assessing and monitoring the communities that comprise them is essential to preserving their stability and ensuring their ...

Uniqueness of Planktonic Ecosystems in the Mediterranean Sea: The Response to Orbital- and Suborbital-Climatic Forcing over the Last 130,000 Years [PDF]

open access: yes, 2016
The Mediterranean Sea is an ideal location to test the response of organisms to hydrological transformations driven by climate change. Here we review studies carried out on planktonic foraminifera and coccolithophores during the late Quaternary and ...

Copepod‐associated microbial biogeography in the epipelagic ocean

open access: yesLimnology and Oceanography Letters, Volume 10, Issue 6, Page 899-910, December 2025.
Abstract Zooplankton‐microbial interactions play crucial roles in epipelagic ecosystem functions. The distinct west‐to‐east gradients and complex circulation patterns in the Mediterranean Sea, combined with the ubiquity of pelagic copepods, provide an ideal model to study the ecological processes driving host‐associated microbial spatial distribution ...

Accumulation of DOC in Low Phosphate Low Chlorophyll (LPLC) area: is it related to higher production under high N:P ratio? [PDF]

open access: yes, 2011
The biogeochemistry of carbon and nutrients (N,P) in the surface layer of the ocean strongly depends on the complex interactions between primary producers (phytoplankton) and remineralizers (heterotrophic bacteria).

Groundwater Microbial Diversity Associated With Icelandic Basaltic Subsurface Environments

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Overview of microbial diversity and environmental drivers in Icelandic deep basaltic aquifers. Using 16S rRNA gene metabarcoding across 22 geothermal wells spanning broad temperature, pH, and bedrock‐age gradients, the study reveals distinct bacterial and archaeal community structures shaped by temperature, pH, and host‐rock reactivity.

Is diatom richness responding to catchment glaciation? A case study from Cana+9dian headwater streams

open access: yesJournal of Limnology, 2012
Due to global change affecting glaciers worldwide, glacial streams are seen as threatened environments deserving specific scientific interest. Glacial streams from the Coast Range and Rocky Mountains in British Columbia and at the border to Alberta were ...

Recent Sphagnum expansion into the tundra on the North Slope of Alaska

open access: yesEcological Monographs, Volume 95, Issue 4, November 2025.
Abstract Observations on the North Slope of Alaska have revealed patches of Sphagnum peat within the widespread matrix of tussock tundra on mineral soils. Little is known about the developmental history of these Sphagnum patches and whether they represent incipient peatlands established in response to warming‐related environmental changes.

Oligotrophy: the forgotten end of an ecological spectrum

open access: yesActa Botanica Croatica, 2009
Most studies that consider the relationship of diatoms and water quality have focused their attention on the questions and practicalities of water pollution or perturbations in some form or another. Many models and studies have demonstrated the environmental tolerances or changes in structure of diatom communities related to environmental challenges ...
