Evaluation of Pulp and Paper Properties obtained from Maple Juvenile Wood through Organosolv Alcohol Method Catalyzed by Calcium and Magnesium Salts [PDF]

Iranian Journal of Wood and Paper Industries, 2015
The properties of catalyzed organosolv pulp obtained from maple juvenile wood were studied. The physical properties of fiber (e.g. length, width, and cell membrane thickness) and chemical composition of maple juvenile wood (e.g. average cellulose, lignin,

Ringtail (Bassariscus astutus) survival in southwestern Oregon

The Journal of Wildlife Management, EarlyView.
We captured and monitored radio‐collared ringtails over 2 years to estimate monthly and annual survival rates. We found that annual survival rates were much higher within forested landscapes in Oregon than for populations in the southwestern United States.

PROPRIEDADES FÍSICAS DOS LENHOS JUVENIL E ADULTO DE PINUS ELLIOTTII ENGELM VAR. ELLIOTTII E DE EUCALYPTUS GRANDIS HILL EX MAIDEN

Ciência Florestal, 2012
The juvenile wood presents great difference in its anatomical and physical properties in relation to the mature wood. That heterogeneity of the wood causes a series of upset for the processing industry.

The Swedish Arctic Fox Project: 40 years of research in ecology and conservation

The Journal of Wildlife Management, EarlyView.
The 4 central research themes in The Swedish Arctic Fox Project and key deliverables for practical conservation achieved over 4 decades. Abstract The scientific community widely recognizes the value of long‐term studies, especially those with individual‐level resolution; however, maintaining a consecutive data series is associated with multiple ...

DIMENSÕES DAS FIBRAS E SUA RELAÇÃO COM A IDADE DE TRANSIÇÃO ENTRE LENHO JUVENIL E ADULTO DE Eucalyptus grandis W. Hill ex Maiden

Ciência Florestal, 2017
This study was undertaken to evaluate the fiber dimensions and the transition age between juvenile and mature wood of Eucalyptus grandis . It was selected, based on the Assmann’s dominant diameter, four trees of an experimental stand located in the ...

Northern bobwhites associated with native grass and shrubs have improved survival

The Journal of Wildlife Management, EarlyView.
Survival rates of adult northern bobwhites were improved by a combination of grazed native warm‐season grasses and well‐interspersed shrubs. Our study suggests that incorporating native warm‐season grass cattle forages into existing operations across the southeastern United States may be a viable working‐lands conservation strategy to create habitat ...

Living on the edge: Habitat characteristics of northern myotis at the periphery of its distribution

The Journal of Wildlife Management, EarlyView.
Northern myotis selected tall trees with minimal decay, in patches with other roosting options. In our study area, these trees occurred in narrow bands within an agricultural matrix, differing from contiguous forest at the core of the species' distribution. Nevertheless, bats selected the tallest trees in the densest patches available.

Pteris madhusoodananii (Pteridaceae), a new fern species from India

Nordic Journal of Botany, EarlyView.
Pteris madhusoodananii sp. nov. (Pteridaceae), from the Kolli hills of Eastern Ghats, India, is described. The new taxon is morphologically distinct, characterized by a unique lamina texture and coloration, specific pinna‐pinnule architecture and distinct spore micromorphology.

Trait‐mediated thermal responses and multi‐axis spatiotemporal niche partitioning between coexisting top predators in ponds

Oikos, EarlyView.
Understanding how physiological constraints scale up to realized niche differences remains a central challenge in functional ecology. Temperature strongly influences metabolic performance, activity, and habitat selection in ectotherms, yet few field studies quantify how thermal responses interact with diel and habitat structure to shape predator ...

From traditional practice to unsustainable exploitation: Fruit overharvesting on the endangered relict palm Jubaea chilensis

PLANTS, PEOPLE, PLANET, EarlyView.
Overharvesting of wild edible plants poses a growing threat to plant populations worldwide, particularly for slow‐growing species with limited regeneration. We quantified fruit extraction from the third‐largest known population of Jubaea chilensis—an endangered palm endemic to Chile—modeled the critical harvest threshold, and assessed consumer ...
