We studied morphological relationships within three guilds of gerbillid rodents in Israel. We found a nonrandom pattern of overdispersed means (community-wide character displacement) for upper incisor widths among the species in these three guilds. Upper tooth-row lengths, condylo-basal skull lengths, and tooth-row surfaces displayed similar patterns. We also studied seed-size selection by two ...

Many endangered plants such as Eryngium viviparum (Apiaceae) present a poor germination rate. This fact could be due to intrinsic and extrinsic seed variability influencing germination and dormancy of seeds. The objective of this study is to better understand the physiological mechanism of seed latency and, through artificial intelligence models, to determine the factors that stimulate germinat...

Damage is an important quality factor for grading, marketing, and end use of soybean. Seed damage can be caused by weather, fungi, insects, artificial drying, and by mechanical damage during harvest, transportation, storage, and handling. The current visual method for identifying damaged soybean seeds is based on discoloration and is subjective. The objective of this research was to classify so...

The aim of the research work was to study the genetic variability of sunflower (Heliantus annuus L.) seeds collection. From 1500 available genotypes a set of 120 recombinant inbred lines coming from different countries were selected to perform the study. The genetic variability consisted in two types of experiments: in vivo and in vitro cultures. The recombinant inbred lines were classified usi...

Thionins are small cysteine-containing, amphipathic plant proteins found in seeds and vegetative tissues of a number of plant genera. Many of them have been shown to be toxic to microorganisms such as fungi, yeast, and bacteria and also to mammalian cells. It has been suggested that thionins are present in seeds to protect them, and the germinating seedling, from attack by phytopathogenic micro...

Summary Introduction: The technological advancements in the production of synthetic seeds are critical for preservation valuable genotypes many herbal plants, including Salvia officinalis – sage. Objective: aim this study was production, storage and conversion artificial sage seeds. technology is placing explants capable regeneration into plants a protective casing. Methods: Apical axillary bud...

Respondent-driven sampling (RDS) is a link-tracing sampling method that is especially suitable for sampling hidden populations. RDS combines an efficient snowball-type sampling scheme with inferential procedures that yield unbiased population estimates under some assumptions about the sampling procedure and population structure. Several seed individuals are typically used to initiate RDS recrui...

Extraction of essential oils from medicinal plants has received researcher’s attention as it has a wide variety of applications in different industries. In this study, ultrasonic method has been used to facilitate the extraction of active ingredient anethole from fennel seeds. Effect of different parameters like extraction time (20, 40, and 60 min), power (80, 240, and 400 Watts) and solid part...

A recent research trend in Artificial Intelligence (AI) is the combination of several programs into one single, stronger, program; this is termed portfolio methods. We here investigate the application of such methods to Game Playing Programs (GPPs). In addition, we consider the case in which only one GPP is available by decomposing this single GPP into several ones through the use of parameters...
