The Burrows-Wheeler Transform is a building block for many text compression applications and self-index data structures. It reorders the letters of a text T to obtain a new text bwt(T ) which can be better compressed. This forward transform has been intensively studied over the years, but a major problem still remains: bwt(T ) has to be entirely recomputed whenever T is modified. In this articl...

—Burrowing Owl (Athene cunicularia) populations are declining in many portions of their range, and research and management efforts into stemming declines are underway. One tool with promise is the artificial burrow, which can supplement nesting opportunities and play a role in research, mitigation, translocation, and reintroduction studies. However, few studies directly assess important burrow ...

Re-occupation of existing nesting burrows in the European bee-eater Merops apiaster has only rarely - and if so mostly anecdotically - been documented in the literature record, although such behavior would substantially save time and energy. In this study, we quantify burrow re-occupation in a German colony over a period of eleven years and identify ecological variables determining reuse probab...

The field cricket Gryllus campestris used to be very common throughout Europe, but in recent decades its population has declined. We study ecology and behavior of crickets near the Odolanów, Poland, between 2009 2011, with emphasis on the effects of grazing of cattle and horses on insects population. We compared the number of burrows per square meter on both grazed and non-grazed areas and exam...

SUMMARY Two visits were made to the Chatham Islands in September 1990 and January 1991 to assist with the Chatham Island taiko and Chatham Island petrel recovery programmes. Four new CI taiko were caught and another was recaptured at the three main breeding burrows. A new CI taiko burrow was found this season. The nest chamber of burrow Tuku No. 10 was located and an adult CI taiko was found in...

Failure to consider both the consumptive and non-consumptive effects of predators on prey can lead to erroneous conclusions about the net effect of the relationship. The predatory devil crayfish, Cambarus diogenes Girard functions as an ecosystem engineer constructing extensive burrow systems through aquatic habitats. Despite crayfish posing a serious predation threat, preliminary data indicate...

Some populations of western burrowing owls (Athene cunicularia hypugaea) have declined in recent decades. To design and implement effective recovery efforts, we need a better understanding of how distribution and demographic traits are influenced by habitat quality. To this end, we measured spatial patterns of burrowing owl breeding habitat selection within black-tailed prairie dog (Cynomys lud...

Female common voles live in groups in large burrows whereas males are probably solitary and promiscuous. At high population density, when burrows become a limiting factor, some females are forced to emigrate from their group. To investigate whether these emigrants could share new common burrows with unrelated neighbours, we analysed in the laboratory burrowing and social behaviour in dyads of u...
