A chromosome territory is composed of chromosomal subdomains. The internal structure of chromosomal subdomains provides a structural framework for many genomic activities such as replication and DNA repair, and thus is key to determining the basis of their mechanisms. However, the internal structure and regulating proteins of a chromosomal subdomain remains elusive. Previously, we showed that t...

This section of the Handbook deals with the culture of the Andean region between Ecuador and the northern border of Aymara territory as it was observed by the Spanish conquerors in the 16th century and recorded in surviving documents. This area includes the whole of the desert Coast of Perti and the broken valleys of the Peruvian Highlands, a region which was the home of many different tribes, ...

This paper presents ChroTeMo, a tool for chromosome territory modelling, accompanied by ChroTeVi-a chromosome territory visualisation software that uses the data obtained by ChroTeMo. These tools have been developed in order to complement the molecular cytogenetic research of interphase nucleus structure in a model grass Brachypodium distachyon. Although the modelling tool has been initially cr...

Mobile ad hoc networks (MANETs) are self-configuring infrastructure-less networks comprised of mobile nodes that communicate over wireless links without any central control on a peer-to-peer basis. These individual nodes act as routers to forward both their own data and also their neighbours’ data by sending and receiving packets to and from other nodes in the network. The relatively easy confi...

Loss of function of the RNA helicase maleless (MLE) in Drosophila melanogaster leads to male-specific lethality due to a failure of X chromosome dosage compensation. MLE is presumably involved in incorporating the non-coding roX RNA into the dosage compensation complex (DCC), which is an essential but poorly understood requirement for faithful targeting of the complex to the X chromosome. Seque...

High-quality territories are expected to provide greater fitness return for breeding individuals and, thus, are likely to have higher long-term occupation rate in comparison to low-quality territories. However, if environmental and ecological cues used for territory selection cannot reliably predict true territory quality, a mismatch between preferences and fitness may occur. We suggest that th...

This study examines how an ant colony’s foraging range changes as the colony grows older, and whether colonies preserve their foraging ranges from year to year. Foraging ranges were measured in 88 colonies of known age over the course of 5 years. A seed-eating ant, Pogonomyrmex barbatus, colony lives for 15-20 years, reaching a stable size of about 12 000 workers when it is about 5 years old. O...

Two hypotheses have been proposed to explain the variation in territory size observed within populations. Hypothesis I assumes that individuals can assess the local food density; territory size is then determined by the amount of food contained within the territory (Norman & Jones 1984, McFarland 1986). Under Hypothesis II, an animal defends as large an area as possible and the size of the terr...
