Shallow water marine sediment bacterial community shifts along a natural CO2 gradient in the Mediterranean Sea off Vulcano, Italy. [PDF]

open access: yes, 2014
The effects of increasing atmospheric CO(2) on ocean ecosystems are a major environmental concern, as rapid shoaling of the carbonate saturation horizon is exposing vast areas of marine sediments to corrosive waters worldwide. Natural CO(2) gradients off

Communities that thrive in extreme conditions captured from a freshwater lake [PDF]

open access: yes, 2016
Organisms that can grow in extreme conditions would be expected to be confined to extreme environments. However, we were able to capture highly productive communities of algae and bacteria capable of growing in acidic (pH 2), basic (pH 12) and saline (40

Evolution of lysine and arginine biosynthesis revealed by substrate specificity of lysine biosynthetic enzymes in Thermus thermophilus

open access: yesThe FEBS Journal, EarlyView.
Two enzymes from the Thermus thermophilus lysine biosynthetic pathway, LysZ and LysY, unexpectedly exhibit substrate promiscuity. They are able to recognize the LysW intermediates utilized by the ArgW‐mediated arginine route, even though the bacterium already possesses the canonical arginine biosynthetic pathway.

Extremophiles in an Antarctic Marine Ecosystem [PDF]

open access: yesMicroorganisms, 2016
Recent attempts to explore marine microbial diversity and the global marine microbiome have indicated a large proportion of previously unknown diversity. However, sequencing alone does not tell the whole story, as it relies heavily upon information that is already contained within sequence databases.

Deep- Sea Bacteria And Their Biotechnological Potentials [PDF]

open access: yes, 2004
Deep-sea environment characterized by its low temperature, high hydrostatic pressure, limited nutrient contents, and constant darkness has been a hostile environment for most marine microorganisms.

Predator Avoidance in Extremophile Fish [PDF]

open access: yesLife, 2013
Extreme habitats are often characterized by reduced predation pressures, thus representing refuges for the inhabiting species. The present study was designed to investigate predator avoidance of extremophile populations of Poecilia mexicana and P. sulphuraria that either live in hydrogen sulfide-rich (sulfidic) springs or cave habitats, both of which ...

Feather Microbiota Landscapes: Biogeography and Phenology Shape Feather Microbiota Traits in a Migratory Seabird in a Subantarctic Ecosystem

open access: yesMolecular Ecology, Volume 34, Issue 21, November 2025.
ABSTRACT It is known that phenological changes (i.e., behavioural and sometimes morphological and physiological traits that repeat annually) influence the wildlife gut microbiota. However, it remains largely unknown to what extent geographic variation could modulate the effect that phenology has on wildlife microbiota.

Health Impacts of Traditional Medicines and Bio-prospecting: A World Scenario Accentuating Bhutan's Perspective [PDF]

open access: yes, 2008
Life without natural products is unimaginable. It has provided mankind with oxygen, water, fire, food, clothing, shelter and medicine. Its public health impact is considerably high, especially of traditional medicines and nature-based modern drugs.

Lithium in plants

open access: yesNew Phytologist, Volume 248, Issue 4, Page 1639-1654, November 2025.
Summary The physiological significance of lithium (Li+) remains largely unexplored in plants despite its consistent presence in at least trace concentrations in plant tissues. While Li+ has traditionally been associated with salinity‐like stress symptoms and presumed to utilise sodium (Na+) transport pathways, accumulating evidence points to multiple ...
