Peculiarities of natural regeneration in beech stands of the Ukrainian Carpathians

Наукові праці Лісівничої академії наук України, 2021
The peculiarities of natural regeneration have been studied in beech stands in which management activities are carried out or are absent. Investigated was the dependence of the amount of self-seeding and young growth of beech upon the age of the trees ...

A Forestry Canada Approach to Environmental Forestry

The Forestry Chronicle, 1990
The continued use and development of the forest environment requires that it be treated in a manner that ensures sustainable development. The forest ecosystem available for commercial exploitation has been shown to be finite and human intervention on a large scale is needed to replace, renew and rehabilitate these forests.

Identifying gene expression signatures for risk stratification of postoperative adjuvant chemotherapy in colorectal cancer

FEBS Open Bio, EarlyView.
A novel signature integrating genome‐wide analysis with clinical factors predicts recurrence in stage II colorectal cancer and enables a new risk stratification to guide postoperative adjuvant chemotherapy. Clinical risk stratification for postoperative recurrence in patients with pathological stage II (pStage II) colorectal cancer (CRC) is essential ...

Linking stream ecosystem integrity to catchment and reach conditions in an intensively managed forest landscape

Ecosphere, 2018
Forests are vital to maintaining headwater stream integrity in forested biomes, which ensures the delivery of aquatic ecosystem services downstream. Forest harvesting, however, can alter land–water linkages and compromise stream integrity.

Explaining success and failure in the commons: the configural nature of Ostrom's institutional design principles

International Journal of the Commons, 2016
Governing common pool resources (CPR) in the face of disturbances such as globalization and climate change is challenging. The outcome of any CPR governance regime is the influenced by local combinations of social, institutional, and biophysical factors,

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

FEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

Private and communal lands? The ramifications of ambiguous resource tenure and regional integration in Northern Bolivia

International Journal of the Commons, 2014
Major integration initiatives such as large-scale infrastructure projects are moving forward in Latin America, creating the conditions theorized by the ‘evolutionary theory of land rights’ (ETLR) for the shift from communal to private individual tenure ...

Directed evolution of enzymes at the crossroads of tradition and innovation

FEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Reducing REDD risks: affirmative policy on an uneven playing field

International Journal of the Commons, 2012
In spite of reforms since the end of the colonial period and more-recent discourses of participation and democracy, the forestry policy environment rarely supports the needs or aspirations of rural communities.

Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.
