Burrow webs: Clawing the surface of interactions with burrows excavated by American badgers

open access: yesEcology and Evolution, 2021
Ecosystem engineers are organisms that influence their environment, which includes alterations leading to habitat provisioning for other species. Perhaps the most well‐examined guild of species provisioning habitat for other species is tree cavity ...

Role of Reef-Building, Ecosystem Engineering Polychaetes in Shallow Water Ecosystems

open access: yesDiversity, 2019
Although the effect of ecosystem engineers in structuring communities is common in several systems, it is seldom as evident as in shallow marine soft-bottoms.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS 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.

Seagrass Patch Complexity Affects Macroinfaunal Community Structure in Intertidal Areas: An In Situ Experiment Using Seagrass Mimics

open access: yesDiversity, 2021
Seagrasses, as key ecosystem engineers in coastal ecosystems, contribute to enhancing diversity in comparison with nearby bare areas. It has been proved mainly for epifauna, but data on infauna are still scarce.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Woody encroachment in grassland elicits complex changes in the functional structure of above‐ and belowground biota

open access: yesEcosphere, 2021
Woody plant encroachment affects dry grasslands globally. To predict changes in biodiversity and ecosystem processes, it is important to understand how this process affects the functional composition of grassland organism groups.

Crustaceans in Phragmatopoma sp. (Polychaeta: Sabellariidae) intertidal reefs, Pacific, Costa Rica

open access: yesCuadernos de investigación UNED, 2023
Introduction: Annelid polychaete worms of the family Sabellariidae build reefs by cementing together sand grains. These reefs increase local habitat heterogeneity and species diversity.

Epigenetic reprogramming of lineage switching in cancer

open access: yesFEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Termite mound cover and abundance respond to herbivore‐mediated biotic changes in a Kenyan savanna

open access: yesEcology and Evolution, 2021
Both termites and large mammalian herbivores (LMH) are savanna ecosystem engineers that have profound impacts on ecosystem structure and function.

Engineering the global ecosystem [PDF]

open access: yesClean 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.
