Despite common use, the efficacy of artificial breeding sites (e.g., nest boxes, bat houses, artificial burrows) as tools for monitoring and managing animals depends on the demography of target populations and availability of natural sites. Yet, the conditions enabling artificial breeding sites to be useful or informative have yet to be articulated. We use a stochastic simulation model to deter...

The artificial neural networks, the learning algorithms and mathematical models mimicking the information processing ability of human brain can be used non-linear and complex data. The aim of this study was to predict the breeding values for milk production trait in Iranian Holstein cows applying artificial neural networks. Data on 35167 Iranian Holstein cows recorded between 1998 to 2009 were ...

owing to reduction of sturgeon stocks in various water bodies, artificial propagation has become significantly important for stock restoration and appropriate broodstock selection is vital in this process. selection of suitable broodstocks may influence the quality and quantity of obtained eggs and larva. the present study aimed to examine correlation between some morphometric and reproductive ...

We are interested in developing intelligent systems for music composition. In this paper we focus on our research into generative rhythms. We have adopted an Artificial Life (A-Life) approach to intelligent systems design in order to develop generative algorithms inspired by the notion of music as social phenomena that emerge from the overall behaviour of interacting autonomous software agents....

This is the description of how nine Aedes aegypti larvae were found in a natural breeding site in the Pinheiros neighborhood, city of Sao Paulo, SP, Southeastern Brazil. The record was conducted in December 2014, during an entomological surveillance program of dengue virus vectors, with an active search of potential breeding sites, either artificial or natural. FindingAe. aegypti larvae in a tr...

The aim of this study was to evaluate the effect of semen collection method (artificial vagina compared to electroejaculation), season in which the semen was collected (breeding season compared to non-breeding season), freezing extender (Biladyl(®), Andromed(®) and skim milk based extender) and pre-treatment procedure (washing compared to non-washing) on post-thaw semen quality in buck. Ejacula...

This paper presents an account of the work of visual artists applying artificial evolutionary techniques, addressing the implications of these techniques for artistic practice. It examines the forms of artistic or creative agency found within the field, the nature of the evolved aesthetic object, and the possible limits to this work.

Horse breeding is the procedure by which an adequate number of sperm are deposited into the uterus of a “healthy” mare at the right time. Although semen deposition is performed in all breeds by natural cover (NC), it is often, and with increasing frequency, done artificially. Although the main difference between natural breeding and artificial insemination (AI) is the delivery method of semen i...

To provide a scientific basis for artificial culture, the effects of different breeding densities, feeding cycles, and light environments on the growth regulation of Poecilobdella manillensis were studied. After P. manillensis were cultured at breeding densities of 250 ~ 3250 leeches m-2; feeding cycles of 2 ~ 16 days; and a light environment with noise or a light-free environment without noise...
