Niche Occupation Limits Adaptive Radiation in Experimental Microcosms [PDF]

, 2007
Adaptive radiations have played a key role in the evolution of biological diversity. The breadth of adaptive radiation in an invading lineage is likely to be influenced by the availability of ecological niches, which will be determined to some extent by ...

FSP1-positive fibroblasts are adipogenic niche and regulate adipose homeostasis

PLOS Biology, 2018
Adipocyte progenitors reside in the stromal vascular fraction (SVF) of adipose tissues that are composed of fibroblasts, immune cells, and endothelial cells. It remains to be elucidated how the SVF regulates adipocyte progenitor fate determination and adipose homeostasis. Here, we report that fibroblast-specific protein-1 (FSP1)+ fibroblasts in the SVF

SCARECROW is involved in positioning the stem cell niche in the Arabidopsis root meristem [PDF]

Genes & Development, 2003
Stem cells self-renew and produce daughter cells that differentiate. How stem cells are specified and maintained is a central question in developmental biology. Plant stem cells occupy a small region or niche in larger zones of mitotic activity called meristems.

Habitat niches of bird species along a recovery gradient in the Chocó tropical forest

Ecological Indicators
Conservation programs need improved tools to measure the recovery of animal diversity across restoration gradients. We used soundscapes and expert identifications of bird species to calculate niche position (i.e., mean of environmental conditions across ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Interconnectedness of the Grinnellian and Eltonian Niche in Regional and Local Plant-Pollinator Communities

Frontiers in Plant Science, 2019
Understanding the causes and consequences of coexistence and thus biodiversity is one of the most fundamental endeavors of ecology, which has been addressed by studying species’ requirements and impacts – conceptualized as their Grinnellian and Eltonian ...

Improvements of Population Fitness and Trophic Status of a Benthic Predatory Fish Following a Trawling Ban

Frontiers in Marine Science, 2021
Trawl fisheries have been shown to cause overfishing and destruction of benthic habitats in the seabed. To mitigate these impacts, a trawling ban has been enforced in Hong Kong waters since December 31, 2012 to rehabilitate the ecosystem and enhance ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

La niche écologique, mythe ou réalité ? [PDF]

, 1979
The niche concept in ecology can be approached either empi rically or theoretically. The emphasis is laid in this paper on the empirical approach, and the authors make use of their per- sonnal field experience to illustrate the points discussed.

When shifting backfires: the electoral consequences of responding to niche party EU positions [PDF]

Journal of European Public Policy, 2019
Recent research has shown that mainstream political parties shift their positions on European integration in response to threats from niche parties. Whether or not this strategy affects the electoral fortunes of mainstream parties remains unclear, however.
