Engineering the global ecosystem [PDF]
Clean Technologies and Environmental Policy, 2010 In 1952, Isaac Asimov wrote a vivid tale about human explorers engineering the ecosystem of Mars to make it habitable for humans (Asimov 1952). In science fiction, engineers use terraforming machines to modify the atmosphere, landscape, and hydrology of Mars to create ecosystems that sustain earth-based life-forms.

Ecosystem engineering and biodiversity in coastal sediments: posing hypotheses [PDF]
, 2009 Coastal sediments in sheltered temperate locations are strongly modified by ecosystem engineering species such as marsh plants, seagrass, and algae as well as by epibenthic and endobenthic invertebrates.

Global change accelerates carbon assimilation by a wetland ecosystem engineer
Environmental Research Letters, 2015 The primary productivity of coastal wetlands is changing dramatically in response to rising atmospheric carbon dioxide (CO _2 ) concentrations, nitrogen (N) enrichment, and invasions by novel species, potentially altering their ecosystem services and ...

High Diversity and Abundance of Foraminifera Associated with Mediterranean Benthic Red Algae Mats
Diversity, 2021 The Mediterranean Sea comprises habitats such as Posidonia oceanica seagrass meadows that exhibit high associated biodiversity of sessile organisms. Recent pilot research indicates that benthic mats formed by the scarcely investigated fleshy red alga ...

Computer modelling the Serengeti-Mara ecosystem [PDF]
, 2003 At present, the viability of biodiversity in most of the remaining natural areas of the world is primarily threatened by human encroachment. This has led to an increased demand for active conservation.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Sessile macro-epibiotic community of solitary ascidians, ecosystem engineers in soft substrates of Potter Cove, Antarctica [PDF]
Polar Research, 2015 The muddy bottoms of inner Potter Cove, King George Island (Isla 25 de Mayo), South Shetlands, Antarctica, show a high density and richness of macrobenthic species, particularly ascidians.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
