This article introduces the turtle++ library which combines constraint-based and imperative paradigms and enables in this way constraint imperative programming (CIP) with c++. Integrating CIP into c++ allows to exploit the powerful expressiveness of the CIP paradigm within a language widely used and accepted in practice. We discuss the main concepts and implementation and illustrate programming...

The intense exploitation of turtles in Asian markets has contributed to declines in turtle populations across the continent. Threequarters of Asia’s turtles are threatened and half are endangered. A recent workshop on the Asian turtle crisis identified taxonomic studies of widespread species as a priority for research because these low risk species may include unrecognized, narrowly distributed...

Loggerhead turtles are vulnerable to natural and anthropogenic environmental pressures due to their longevity, global distribution, and their migratory way of life. Two significant environmental conditions, temperature and available food, have been correlated to growth, reproduction, and maturation of loggerhead turtles, often accounting for most of the observed variability. With the current an...

Painted turtles (Chrysemys picta) have a natural history unlike that of other chelonians from the northern United States and southern Canada. Although neonates of other freshwater turtles usually emerge from their subterranean nests in late summer or autumn and move to nearby marshes, lakes, or streams to spend their first winter, hatchling painted turtles typically remain inside their shallow ...

During the reproductive season, sea turtles use a restricted area in the vicinity of their nesting beaches, making them vulnerable to predation. At Raine Island (Australia), the highest density green turtle Chelonia mydas rookery in the world, tiger sharks Galeocerdo cuvier have been observed to feed on green turtles, and it has been suggested that they may specialise on such air-breathing prey...

—Alteration and loss of habitat is a major factor in the recent declines of many turtle populations. However, there are few studies of turtle populations in areas that are used intensively by humans. We used temporal symmetry modeling and an information-theoretic approach to model selection to estimate survival and recruitment in a population of Ornate Box Turtles, Terrapene ornata, in fragment...

Turtle Mountain, the site of the 1903 the Frank Slide, has been widely studied. A large database of structural measurements allows the comparison and testing of recently developed techniques. This paper commences with a review of recent mapping of Turtle Mountain. A report on a recent investigation of the mountain using a combination of airborne and terrestrial laser scanning techniques is then...

All seven extant species of sea turtles are considered endangered or threatened with extinction. Because of their commercial value for food (particularly the green turtle) and for craft materials (bekko or tortoiseshell from the hawksbill turtle) they have been heavily exploited around the world. Sea turtles are also charismatic animals to view in large aquaria and three species have proven eas...

A common analogy for describing newly diagnosed prostate cancer patients is to think of turtles, rabbits, and birds. This is an analogy that prostate cancer appears to be attributable to Hinman, who borrowed from Crile when applied to breast cancer (1). Turtles are patients with very slow growing disease. Their disease grows so slowly that they need not be diagnosed, for the disease will never ...
