Nine taper equations were tested to predict diameters inside bark along the stem for <i>Pinus oocarpa</i> Schiede trees growing in natural stands of central Honduras.</p><p> A five parameter submodel predicted as well as an eight parameter model proposed by Kozak, 1988. Taper variation was explored between two geographic regions from which trees with different taper were suspected. Results showed that different site classes, not fully accounted for in the model, might have an effect on the prediction of taper in each region. Also, the effect of crown class and live crown ratio on predict

Abstract:

Pinus nigra subsp. pallasiana is one of the most widespread and economically important forest tree species in Turkey. Primary objective of the present study was to to reveal the effects of forestry practices by determining genetic diversity of natural and managed seed sources by means of RAPD markers. Secondly, two varieties were also investigated to reveal their pattern of genetic variation. Seed stands, seed orchards and plantations were screened against 11 RAPD primers and generated 152 polymorphic DNA loci. Two varieties were compared with a reference seed source and 4 natural seed sources

PrognosisBC, a spatially-implicit growth model, lacked a submodel suitable for predicting natural regeneration in unsalvaged MPB-disturbed stands.

Abstract:

Consistent patterns of foliar N concentration and δ<sup>15</sup>N were found in age sequences of foliage. N concentration decreased with age and δ<sup>15</sup>N increased with age. Patterns of δ<sup>15</sup>N may be useful in studying nutrient retranslocation within the canopy because, as far as it is known, they are unaffected by contemporary changes in other leaf components. No evidence for increased efficiency of N recycling in spruce from mixed stands as compared to spruce from pure stands was found. The δ<sup>15</sup>N data appear to confirm that the amount of N retranslocated depends on

Two new methodologies were created: STRUX Index that facilitates structure classification, and Natural Regeneration Classification that studies the viability of natural regeneration.

Speciation – the process by which new species arise – is of fundamental importance in the biological sciences. The means by which new species arise, and the relationship among living species, has been a topic that has captivated both lay and scientific observers for centuries. In recent years, the study of speciation has enjoyed increased attention, resulting in significant advances in our understanding of how species form. Although our understanding of the processes that contribute to speciation has increased dramatically in recent years, our knowledge of how reproductive barriers accumulate

A mosquito vector will ingest mature gametocytes during a blood meal. Sexual reproduction will occur in the midgut, leading to the production of sporozoites that will migrate to the salivary gland.

Old-growth stands are populated by mountain hemlock, Pacific silver fir, and Alaska yellow-cedar, and are among the least-disturbed ecosystems in the world.
