Circular 53 [PDF]

open access: yes, 1986
The regeneration of interior Alaska’s commercial forest lands is mandated by Alaska’s Forest Resources and Practices Act (1979). This act requires that regeneration be established adequate to ensure a sustained yield on forested lands from which the ...

Tree planting, natural colonisation, hybrid approaches: Land manager decisions explored

open access: yesPeople and Nature, EarlyView.
Abstract There is a global drive to protect biodiversity and help combat climate change. In the UK, this is expressed in a number of policy initiatives and tools that include increasing tree cover as an important nature‐based solution to achieving national policy targets.

Synthesizing current knowledge on the ecology, phenology, and cultivation of Vaccinium membranaceum

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
More than 100 edible native berries grow across Canada's vast territory and are used by over 600 Indigenous Peoples of Canada as a main component of their diet. This research provides critical insights into the ecology, phenology, and cultivation of black huckleberry (Vaccinium membranaceum), a species of significant ecological and cultural importance ...

Natural Regeneration in a Multi-Layered Pinus sylvestris-Picea abies Forest after Target Diameter Harvest and Soil Scarification

open access: yes, 2017
Forest management in Sweden can be characterized by even-aged silviculture heavily relying on three established harvest regimes: clearcutting, the seed-tree method, and the shelterwood system.

Positron Emission Tomography/Computed Tomography Imaging‐Guided Polydopamine Nanoparticles Attenuate Foam Cell Ferroptosis for Targeted Antiatherosclerotic Therapy

open access: yesSmall Science, EarlyView.
Folate‐ and arginine‐modified polydopamine nanoparticles (FPLG NPs) are designed for the specific targeting of atherosclerotic foam cells. These nanoparticles combat ferroptosis by scavenging reactive oxygen species, regulating iron/lipid metabolism, and upregulating the GPX4/NRF2 pathway. Using chelator‐free 68Ga‐labeling, positron emission tomography/

I. Acid treatment and mechanical scarification [PDF]

open access: yesNew Zealand Journal of Experimental Agriculture, 1975
Abstract Only about 30% of the Centrosema pubescens (centro) seed examined germinated under favourable conditions of moisture and temperature. Germination percentage increased to more than 80% after seed treatment with concentrated sulphuric acid or by mechanical scarification.

Impact of forest management regimes on ligneous regeneration in the Sudanian savanna of Burkina Faso [PDF]

open access: yes, 2007
Annual early fire, selective tree cutting and grazing exclusion are currently used to manage the State forests of the Sudanian savanna of Burkina Faso, West Africa. Such prescriptions, however, are not based on experimental evidence.
