PROGENY TESTS WITH FOREST TREES

Optimal search trees with equality tests

We study the following problem: given a set of keys and access probabilities, find a minimum-cost binary search tree that uses only 2-way comparisons (=, <,≤) at each node. We give the first polynomialtime algorithm when both successful and unsuccessful queries are allowed, settling a long-standing open question. Our algorithm relies on a new structural theorem that proves a conjecture of Spule...

Report of five species of plant parasitic nematodes associated with hawthorn forest trees in western Iran

Z, Bazgir E, Naghavi A (2020) Report of five species of plant parasitic nematodes associated with hawthorn forest trees in western Iran. Plant Pathology Science 9(1):16-30. DOI: 10.2982/PPS.9.1.16 Introduction: The Hoplolaimidae family is one of the largest and economically most important families of the order/ infraorder Tylenchida / Tylenchomorpha. The members of this family spread all over ...

Species Diversity of Trees and Forest Floor Plants in Oriental beech Forest Types of Shastkalate Educational and Research Forest, Gorgan)

Trees are the most important biological elements of forest ecosystems. The variability of the tree species composition inhabiting in the Oriental beech forest, not only forms different forest types but also has a remarkable impact on the species diversity of forest floor plants, due to the existence of trees in the overstory layer. In this research, forest types of an an Oriental beech were ide...

Population and conservation genomics of forest trees: seeing the forest for the trees

Background Forest trees exhibit striking adaptations to the environments in which they grow. A long history of quantitative genetic experimentation has established the genetic basis for many traits, which are likely adaptive since many of them are also correlated with environmental heterogeneity. The genes underlying these traits, however, have largely remained elusive. Recent applications of h...
