Ecological research should consider Indigenous peoples and stewardship

FACETS, 2020
The relationship between Indigenous peoples and the functioning of terrestrial ecosystems has received increased attention in recent years. As a result, it is becoming more critical for researchers focusing on terrestrial ecosystems to work with ...

The globalization of naval provisioning: ancient DNA and stable isotope analyses of stored cod from the wreck of the Mary Rose, AD 1545 [PDF]

Royal Society Open Science, 2015
A comparison of ancient DNA (single-nucleotide polymorphisms) and carbon and nitrogen stable isotope evidence suggests that stored cod provisions recovered from the wreck of the Tudor warship Mary Rose, which sank in the Solent, southern England, in 1545,

Historical Fires Induced Deforestation in Relict Scots Pine Forests during the Late 19th Century

Fire, 2021
Mountain forests are subjected to several pressures including historical land-use changes and climate warming which may lead to shifts in wildfire severity negatively impacting tree species with low post-fire growth resilience. This is the case of relict

Historical influences on community ecology [PDF]

Proceedings of the National Academy of Sciences, 2005
Vitt and Pianka's analyses revealed significant dietary shifts at six major divergence points. Why does California, a large and topographically complex state that spans fogdrenched redwood groves to desert sand dunes, have 30 species of snakes, whereas roughly twice that number occur in five square miles of lowland Costa Rican rainforest?

Historical ecology of forest garden management in Laxyuubm Ts’msyen and beyond

Ecosystems and People, 2023
Cultural land-use is an important driver of ecosystem change, influencing the composition of species across landscapes and through time. Recent research in northwestern North America has shown that historical Indigenous land-use and forest management has

Review of considerations for restoration of tule elk to the San Francisco Peninsula and northern Monterey Bay counties of California

California Fish and Wildlife Journal, 2022
Successful translocations of tule elk (Cervus canadensis nannodes) have been conducted since the early 1900s, with their state population rising from a nadir of as few as three surviving individuals to about 500 when reintroductions began, and to over 5 ...

The prelude to industrial whaling: identifying the targets of ancient European whaling using zooarchaeology and collagen mass-peptide fingerprinting

Royal Society Open Science, 2023
Taxonomic identification of whale bones found during archaeological excavations is problematic due to their typically fragmented state. This difficulty limits understanding of both the past spatio-temporal distributions of whale populations and of ...

Spatial biology in cancer epigenetics

Molecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...
