Cape Breton Provides Pointers for the Adjustment Programs Required by the Decline of the Old Economy (Working Paper 14)

The Cape Breton Development Corporation need not, should not, be dying in the way it is. “Devco” has been widely represented as a failure dragged out too long. In fact it had for a time considerable success in a role too difficult to be often attempted. The main failure was in the political will to stick to its purpose. This commentary is in three parts. The first, major section discusses the purpose of Devco and the policies that served the purpose quite well but were maintained for little more than a decade. It suggests that the benefits would have been greater if Devco had been started earlier in the period of postwar prosperity. The second section comments on the enfeeblement of Devco in the 1980s. The removal of its development function also weakened, and has eventually led to the abandonment of, Devco’s social purpose in the operation of coal mining. Third, a short epilogue pointing out that, while the Cape Breton case is extreme, there will be increasing need to moderate the socially disruptive consequences of accelerating economic change. There are lessons from the Devco experience: the longer remedial action is delayed, the more difficult and expensive it becomes, and the more necessary for its effectiveness is a steady political will.

Loggerhead nesting trend in three beaches of Boavista, Cape Verde archipelago

[EN] Nesting beach surveys are the most widely implemented monitoring tool in use by the global sea turtle community and are an important component of a comprehensive program to assess and monitor the status of sea turtle populations. These assessments are necessary to evaluate the effects of recovery and conservation activities that are being implemented at all life history stages. Monitoring techniques employed on nesting beaches range from highly structured standardized sampling to “snapshots” of nesting activity within a nesting season. Very long-term nest counts data (more than twenty years) were analyzed for some turtle populations.

Temporary sequences and description of the emergency of newborns loggerhead in the Cape Verde archipelago

[EN] Sea turtles bury their eggs in the sand of the beach, where they incuba te. After a period of approximately two months, hatchlings break the eggshell and remain inside the chamber for three to seven days (Hays & Speakman, 1993). Then they leave the nest and emerge to the surface of the beach, going quickly towards the surf, to begin their pelagic and developmental stage (e.g., López-Jurado & Andreu, 1998). Hatchlings usually do not emerge from the nest as a single group. They emerge in groups at different moments, resulting in more than one emergence per nest during sorne days (Whitherington et al.,4 1990; Hays et al., 1992; Peters et al., 1994).

Comparative study of the epibionts on the pelagic and mature female loggerhead turtles on the Canary and Cape Verde islands

[EN] Marine turtles commonly carry diverse forms of epizoa on their shells. The occurrence of a particular species may ultimately help to clarify certain questions about sea turtle natural life history. This paper gives a detailed and comparative list of epizoic species found on two populations of macaronesian loggerheads: pelagic and juveniles living around the Canary Islands and mature females nesting in Boavista Island, Cabo Verde. For the epizoic flora, the most important genera founded is Polysiphonia (Rhodophiceae); P. carettia for the pelagics and Polysiphonia sp. for the nesting animals.
