Estimation of Leaf Area Index in Dwarf Mountain Pine (pinus Mugo Turra) Using Hyperspectral Data
The natural environment of the Tatras is one of the most diverse in Europe in terms of species richness and ecological value. This mountain range is well preserved and constitutes an important part of Europe’s nature resources. Dwarf pine (Pinus mugo Turra) is the main component of the Tatras subalpine belt covering altitude between 1550 and 1800 m a.s.l. It is a very dynamic species, which exp...
متن کاملSpatial pattern of allozyme variation in a contact zone of Pinus Ponderosa and P. arizonica (Pinaceae).
The spatial distribution of genotypes for nine polymorphic allozyme loci was examined in a contact zone between Pinus ponderosa var. scopulorum and another tree regarded as either a separate species, Pinus arizonica, or variety, Pinus ponderosa var. arizonica, in southern Arizona. Previous work had identified a steep elevational cline for a key taxonomic trait, number of leaf-needles per fascic...
متن کاملClinal differentiation and putative hybridization in a contact zone of Pinus ponderosa and P. arizonica (Pinaceae).
The widely distributed Pinus subsection Ponderosae is a species complex that has a transition zone among taxa in the southwestern United States. In southern Arizona and New Mexico at least two recognized taxa, Pinus ponderosa var. scopulorum and Pinus arizonica or P. ponderosa var. arizonica, are known to coexist in close proximity. In this study, we report the existence of populations where th...
متن کاملSpontaneous Hybridization between Pinus mugo and Pinus sylvestris at the Lithuanian Seaside: A Morphological Survey
We address the problem of spontaneous hybridization between an exotic species Pinus mugo and the native/local P. sylvestris at the seaside spit of Kursiu Nerija in Lithuania. The objective was to identify spontaneous hybrids between P. mugo and P. sylvestris based on morphology traits among the individuals naturally regenerating at the seaside spit. The field inventory was carried out over the ...
متن کاملMicrosatellite primers in the foundation tree species Pinus edulis and P. monophylla (Pinaceae)1
UNLABELLED PREMISE OF THE STUDY Microsatellite primers were developed in the foundational tree species Pinus edulis to investigate population differentiation of P. edulis and hybridization among closely related species. • METHODS AND RESULTS Using a hybridization protocol, primer sets for 11 microsatellite loci were developed using megagametophyte tissue from P. edulis and scored for polym...
