Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Some observations of slime moulds on wood and litter of beech forests

open access: yesActa Mycologica, 2013
The results of research into slime moulds in beech forest reserves in Central Poland are discussed. Thirty species of slime moulds directly associated with beech wood and beech litter were recorded. Species associated with different decay phases of beech

Improvement of seed germination of Fagus orientalis Lipsky [PDF]

open access: yes, 2003
This thesis was seeking two main approaches for improvement of seed germination of oriental beech, a timber producing species in Hyrcanian forests in northern Iran. Germination behavior of beechnuts was enhanced either by decreasing the dormancy breakage

Sanitation felling against the European spruce bark beetle: A matter of intensity and forest type Tagli fitosanitari contro il bostrico tipografo: una questione di intensità e tipologia forestale

open access: yesAgricultural and Forest Entomology, EarlyView.
We assess the effect of sanitation felling performed in 2022 in North‐Eastern Italy on bark beetle damage that occurred in 2023 across eight spruce forest types, as evaluated using multispectral satellite imagery. Bark beetle damage was reduced only at very high or very low sanitation felling rates.

Preliminary results from simultaneous planting of Fagus sylvatica and pioneer species on calamity clearings

open access: yesJournal of Forest Science
We compared the biological and economic effects of simultaneous artificial regeneration of mixtures of pioneers (birch - Betula pendula Roth or aspen - Populus tremula L.) and beech (Fagus sylvatica L.) with plots of monospecific beech. During the period

Evaluation of the genetic diversity of selected Fagus sylvatica L. populations in the Czech Republic using nuclear microsatellites

open access: yesJournal of Forest Science, 2017
Fagus sylvatica Linnaeus (European beech), the ecologically and economically most important broadleaved tree species in the Czech Republic, was strongly reduced in the past.

Influence of selected environmental factors on moisture dynamics of beech wood [PDF]

open access: yes, 2016
Beech is one of the most important tree species in Slovenia. Unfortunately, there is much more beech wood incremented annually than consumed. Thus, it is of great importance to develop new applications for use of beech wood. One of the possible solutions

Landscape and Geography Determine Saproxylic Beetle Captures in Pheromone‐Baited Traps

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Pheromone‐baited traps at 39 forest sites across southern Sweden captured 58 saproxylic beetle species, including seven Red‐listed taxa. The effect of surrounding forest cover on beetle abundance may depend on latitude and longitude: positive effects were strongest in warmer southern and eastern regions but weakened or reversed in colder northwestern ...

Predation on Artificial Caterpillars Varies With Vertical Stratification but Not Light Gradients in a Sugar Maple Temperate Forest

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Predation pressure varies vertically, with highest arthropod predation in the understory and highest bird predation in the canopy. Light availability differs across vertical strata, but predation patterns are more strongly influenced by height and forest structure than by light gradients.

Stammbewohnende Weberknechte (Arachnida: Opiliones) in einem Fichten- einem Misch- und einem Buchenbestand im Solling

open access: yesArachnologische Mitteilungen, 2006
In the Solling mountains (Southern Lower Saxony, Germany) the fauna was sampled for one year with stem eclectors in adjacent spruce, mixed (spruce/beech), and beech stands. The tree age was more than 90 years.
