UJI COBA ALAT KABEL LAYANG P3HH24 UNTUK MENGELUARKAN KAYU PINUS HASIL PENJARANGAN DI AREAL BERBUKIT

Jurnal Penelitian Hasil Hutan (Journal of Forest Products Research), 2016
Di hutan tanaman pinus, kayu hasil penjarangan biasanya dikeluarkan dari hutan secara manual yaitu dengan dipikul. Namun, bila kondisi lapangan berbukit-bukit sampai topografi berat, pengeluaran kayu secara manual dirasa kurang manusiawi dan kurang ...

Amanita theophili sp. nov. (Amanitaceae) from central Mexico

Nordic Journal of Botany, EarlyView.
Amanita theophili sp. nov., a member of Amanita sect. Amidella (Amanitaceae), is described from temperate pine‐oak forests in Morelos, central Mexico. Morphological features and phylogenetic analyses based on ITS and 28S rDNA sequences confirm its distinct taxonomic status. The new species is morphologically similar to A. peckiana and A.

Seed co‐occurrence caused by shared frugivores leaves a long‐lasting signal in the spatial co‐occurrence among plants

Oikos, EarlyView.
By dispersing seeds, frugivorous animals affect spatial co‐occurrence of plants, ultimately influencing plant community dynamics. Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence.

Distribución potencial de Pinus cembroides, Pinus nelsonii y Pinus culminicola en el Noreste de México/Potential distribution of Pinus cembroides, Pinus nelsonii and Pinus culminicola in northeastern Mexico

Ecosistemas y Recursos Agropecuarios, 2018
El clima del mundo está cambiando de forma signicativa en los últimos años y con ello la distribución de las especies. El objetivo del estudio fue generar modelos de distribución potencial de las especies de pinos piñoneros Pinus cembroides, P. culminicola y P. nelsonii del noroeste de México.

Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

Oikos, EarlyView.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

Micropropagation of a recalcitrant pine (Pinus pinea L.): An overview of the effects of ectomycorrhizal inoculation [PDF]

, 2013
Stone pine (Pinus pinea L.) is an economically important forest species in some regions of Iberian Peninsula. Portugal and Spain have nearly 500,000 ha of stone pine stands, representing 85% of worldwide distribution.

Community dynamics of lignicolous lichens on standing deadwood in a 275‐year chronosequence

Oikos, EarlyView.
Dead trees provide discrete habitat patches in which patch quality changes gradually due to wood decomposition. Although in most cases these patches persist for not more than a few decades, in some ecosystems deadwood decomposition and the consequent change in habitat patch quality can be a centuries‐long process, potentially leading to dynamics of ...

Fire buffers drought impacts on reproduction in a resprouting Mediterranean shrub

Oikos, EarlyView.
Fire and drought increasingly co‐occur, exposing plants to greater drought stress during post‐fire resprouting. Yet, the effect of this combination of disturbances on plant fitness remains poorly understood. Here, we examine how post‐fire resprouting influences reproductive success under drought conditions in the Mediterranean shrub Anthyllis ...

Natural recovery of genetic diversity by gene flow in reforested areas of the endemic Canary Island pine, Pinus canariensis

, 2007
The endemic pine, Pinus canariensis, forms one of the main forest ecosystems in the Canary Islands. In this archipelago, pine forest is a mosaic of natural stands (remnants of past forest overexploitation) and artificial stands planted from the 1940's ...

Species identity and spatial scale drive context‑dependent tree diversity effects in a Finnish forest experiment

Oikos, EarlyView.
Tree species diversity is known to affect tree growth and leaf traits, which in turn can influence various ecosystem processes. However, the reported direction of these tree diversity effects is inconsistent, indicating that their outcomes depend strongly on ecological context.
