A twofold development and demise of pine stands in the Netherlands during the Allerød interstadial: two hypotheses to explain a link to climate change recorded in Greenland ice

Journal of Quaternary Science, EarlyView.
ABSTRACT The second half of the Allerød interstadial in the Netherlands is characterised by pine forest. Excavated trunks of 165 pine trees at Leusden‐Den Treek in the central Netherlands (LETR16) were dated by dendrochronology and radiocarbon. Two chronologically separated pine forest phases occurred during relatively warm periods as recorded in ...

Generalized height-diameter models for five pine species at Southern Mexico

Forest Science and Technology, 2020
Generalized height-diameter at breast height (D) models are essential for the estimation of the timber stocks of a forest stand, as well as in the generation of base information to develop forest growth models, and as basic inputs in the development of ...

Insights into Red Deer Ecology during the Late Epigravettian: New isotopic evidence from Riparo Tagliente (Italian Prealps)

Journal of Quaternary Science, EarlyView.
Abstract The transition from the Last Glacial Maximum to the Late Glacial marked a shift from the cold conditions of Greenland Stadial‐2 (GS‐2) to the warmer phases of Greenland Interstadial‐1 (GI‐1), enabling the reoccupation of Alpine regions by Late Palaeolithic hunter‐gatherers.

Epsomite as flame retardant treatment for wood: Preliminary study [PDF]

, 2016
The effect of epsomite as flame retardant for wood has been investigated and compared with a commercial boron salt. Both flame retardants have been introduced into wood samples by vacuum impregnation.

Moose indifferent to canopy loss from forest disturbance by bark beetles

The Journal of Wildlife Management, EarlyView.
Moose showed strikingly similar patterns of habitat selection before and after widespread forest disturbance following an infestation of bark beetles. Our findings indicate that beetle‐kill does not appreciably alter habitat quality for moose and highlight the importance of riparian areas in sustaining moose as they contend with changing forests ...

A study of fossil plant remains at the archaeological site in Lomilla (Aguilar de Campoo, Palencia, Spain)

Anales del Jardín Botánico de Madrid, 2001
The discovery of a site with abundant fossil plant remains in the surroundings of Aguilar de Campoo (Palencia, Spain), dated in the early Holocene, allowed us to obtain new data on the composition of foreste in that área. Two species of Pinus and several

Drought influence over radial growth of Mexican conifers inhabiting mesic and xeric sites [PDF]

, 2017
Drought is a major constraint of forest productivity and tree growth across diverse habitat types. In this study, we investigated the drought responses of four conifer species growing within two locations of differing elevation and climatic conditions in

Wild pig habitat use impacted by prescribed fire in the William B. Bankhead National Forest, USA

The Journal of Wildlife Management, EarlyView.
Natural resource management activities like integrated wild pig control programs and 3–5‐year interval prescribed burning can reduce wild pig activity and habitat but can have an unintended side effect of allowing them to thrive in sensitive and protected areas, where access and tools are restricted.
