The effect of leaf feeder moth (Erannis defoliaria & Operophtera brumata) on radial growth of 3 tree species in north of Iran (case study: Mashalak, Nowshahr) [PDF]

تحقیقات جنگل و صنوبر ایران, 2007
In this study it has been considered that the inflict of two species, Erannis defoliaria and Operophtera brumata,decrease the radial growth of beech, maple and hornbeam in northern forests of Iran. 30 cores were prepared from each species and annual ring

Edges as ecological filters: Asymmetrical orientation‐specific arthropod activity across forest boundaries

Insect Science, EarlyView.
Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Investigation of affective habitat factors affecting on abundance of wood macrofungi and sensitivity analysis using the artificial neural network (case study: Kheyrud forest, Noshahr) [PDF]

تحقیقات جنگل و صنوبر ایران, 2014
One advantage of artificial neural networks is application in the management and planning of natural ecosystems. Considering the high biological diversity of northern forests of Iran, it is necessary to know forests ecosystems.

Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)

Agricultural and Forest Entomology, EarlyView.
We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Biochemimechanical pulping of hornbeam chips with Phanerochaete chrysosporium

BioResources, 2012
The effect of fungal pretreatment of Hornbeam (Carpinus betulus) wood chips on the performance of treated pulps was studied. The chips were pretreated with P. chrysosporium BKM-1767 fungus at 1, 2, and 4 weeks using an inoculation temperature and relative humidity of 39 oC and 65%, respectively with two pulping times (80 and 90 min) and three sodium ...
