Although transposable elements (TEs) play significant roles in structural, functional and evolutionary dynamics of the salicaceous plants genome and the accurate identification, definition and classification of TEs are still inadequate. In this study, we identified 18 393 TEs from Populus trichocarpa, Populus euphratica and Salix suchowensis using a combination of signature-based, similarity-ba...

the objective of the study was to evaluate chemical composition, in vitro dry matter digestibility (ivdmd), and growth performance of weanling boer-goats supplemented with cowpea seed hulls (csh) and commercial concentrate / feed (cf) with natural pasture as basal diet. weanling boer-goats (n=36) were assigned to 3 treatments comprising of 4 animals each (2 bucklings and 2 females) replicated t...

An experiment was conducted to determine the influence the time of brush-cutting can have on plant regrowth and attractiveness to herbivores that browse in linear corridors. The influence of cutting time on leaf flush and senescence, shoot morphometry, and biomass was measured for 3 consecutive years after initial brush-cutting. Results indicate that morphological and phenological attributes of...

Dioecious plants usually harbor 'young' sex chromosomes, providing an opportunity to study the early stages of sex chromosome evolution. Transposable elements (TEs) are mobile DNA elements frequently found in plants and are suggested to play important roles in plant sex chromosome evolution. The genomes of several dioecious plants have been sequenced, offering an opportunity to annotate and min...

Metadata that describe characteristics of geographic datasets are used for discovering potential datasets and evaluating their suitability for intended purposes (Guptil 1999, Taylor 2004). Discovery is based on search functions relying on metadata about thematic, spatial, and temporal extents of datasets (Beard and Sharma, 1997) and well developed in directories, clearing houses, and digital li...

A user’s session of information need often goes well beyond his search query and first click on the search result page and therefore is characterized by both search and browse activities on the web. In such settings, the effectiveness of an ad (measured as CtoC ratio, as well as #(conversions) per unit payment) could change based on what pages the user visits and the ads he encounters earlier i...
