Genetic diversity of Heterobasidion spp. in Scots pine, Norway spruce and European silver fir stands

Acta Mycologica, 2013
Investigations of genetic diversity of Heterobasidion spp. in Scots pine, Norway spruce and European silver fir stands indicated that almost all of identified genets occurring in those stands were small and occupied only a single stump. In some cases two,

Identifying forest features that increase resiliency of southern‐boundary snowshoe hare populations in Pennsylvania

The Journal of Wildlife Management, EarlyView.
Snowshoe hare population densities in Pennsylvania were greatest in early‐successional forest and densely‐understoried mature forest. Forest management that increases and maintains the amount of early‐successional forest, or that increases understory complexity in mature forest, would benefit snowshoe hares and may mitigate population declines under ...

MeerKAT 1.3 GHz Observations of Supernova Remnants

The Astrophysical Journal Supplement Series
We present full Stokes MeerKAT L -band (856–1712 MHz) observations of 36 high-latitude supernova remnants (SNRs). Sensitive, high-dynamic-range images show a wealth of structure. G15.1−1.6 appears to be a H ii region rather than an SNR.

Aerial Seeding for Forest and Landscape Restoration: A Systematic Review of Technology, Challenges, and Future Directions

Land Degradation &Development, EarlyView.
ABSTRACT Land degradation is a critical global challenge, threatening biodiversity, food security, and livelihoods. Ecological restoration has therefore become a priority, with aerial seeding emerging as a key method to address issues of scale, accessibility, and efficiency. By dispersing seeds from aircraft or drones, aerial seeding complements ground‐

Far-infrared sauna exposure at 65°C elevates core temperature. [PDF]

Exp Physiol
Abstract Far‐infrared (FIR) saunas are increasingly used as a passive heating and ‘wellness’ modality, yet their capacity to elevate core temperature remains unclear, particularly given prior work at lower temperatures (∼45°C) reports limited net heat storage.

Tree Species Configuration Shapes Soil Phosphorus Fractions and Microbial Communities in Uneven‐Aged Multilayered Chinese Fir–Broadleaved Mixed Forests

Land Degradation &Development, EarlyView.
ABSTRACT Chinese fir (Cunninghamia lanceolata) plantations in southern China are often limited by phosphorus (P) availability, constraining productivity and sustainable management. We hypothesized that multi‐species, multilayered, uneven‐aged configurations would enhance soil P availability by regulating P fractions and microbial P transformation. This

Fir-dominated forests in Bavaria, Germany [PDF]

, 2005
The map of “Regional natural forest composition by main tree species” (WALENTOWSKI et al. 2001) depicts Bavaria as a region largely predominated by the European beech (Fagus sylvatica).
