Amphibian biology is intricate, and there are many inter-related factors that need to be understood before establishing successful Conservation Breeding Programs (CBPs). Nutritional needs of amphibians are highly integrated with disease and their husbandry needs, and the diversity of developmental stages, natural habitats, and feeding strategies result in many different recommendations for prop...
We present a new perspective for the role of Termitomyces fungi in the mutualism with fungus-growing termites. According to the predominant view, this mutualism is as an example of agriculture with termites as farmers of a domesticated fungus crop, which is used for degradation of plant-material and production of fungal biomass. However, a detailed study of the literature indicates that the ter...
Subsequent to World War II, a dramatic increase occurred in the utilization of nonhuman primates in biomedical and psychological research and industry. At the same time field studies on the ecological and social behavior of natural populations of primates also increased, making possible more realistic assessments of both the behavioral potentiality of primate populations and their conservation ...
The pig husbandry is an important economic sector. In the last decade, major changes have been made. As a result, farmers came together to introduce the Eco Label pig, meeting the strong consumer and governmental call for high quality, animal friendly and environmentally friendly food. The market for Eco Label food is expected to grow enormously in the next years, asking for the development o...
A coustical characteristics of vocalizations of sows, piglets, and nursery pigs under selected husbandry practices were analyzed with a digital signal processing system. The duration (D) and major energy-resonance frequency (P) for each call were determined as follows: a) processing of piglets (D = 0.81 s and f* = 3 700 Hz); b) food anticipation of breeding-gestation sows (2.50 s and 3 000 Hz);...
BACKGROUND : We investigated whether independent prognostic factors for overall survival (OS) in non-small cell lung cancer such as ethnicity, smoking history, socioeconomic, and marital statuses are also applicable to extensive stage small cell lung cancer (ED-SCLC). METHODS : SCLC patients diagnosed from 1991 to 2005 from 3 Southern California counties were identified. Prognostic factors fo...
To improve livestock production and to modernize dairy husbandry in Iran, it is essential to disseminate the most recent information on dairy husbandry technologies and management practices through various means among farmers. An understanding of farmers’ communication behaviour is essential in formulating effective communication strategies for livestock development. For the purposes of this st...
