A single PCR on the 12S gene proved to be very suitable for detection and specification of Taenia sp. and Echinococcus sp. Both targets harbour enough polymorphic sites to determine the various Echinococcus species.
This was associated to two different ranging patterns (i.e. sedentary versus wandering respectively) which depended on the ability of the hen and its chicks to settle in suitable areas harbouring enough arthropods and shelter for chicks.
That does not mean old wounds do not run deep though, as some AFC fans who made the trip to Buckinghamshire still harbour enough resentment to feel they needed to rush to the front of the stand after MK's second goal and scamper onto the pitch after their late consolation.
The overall goal of any long-term sustainable conservation policy is to allow populations that are large enough to harbour enough genetic variation so that they can respond and evolve in response to ever-changing selective pressures.
Situated at the centre of the Orkney Islands off the north coast of Scotland, the natural harbour, large enough to contain the entire Grand Fleet, was surrounded by a ring of islands separated by shallow channels subject to fast-racing tides.
The walk also takes in Barafundle beach, which is regularly voted one of Britain's best beaches, thanks to its seclusion and golden sands, and Stackpole Quay, one of the country's smallest harbours, with barely enough room for two boats.
In Charleston, South Carolina, which nowadays grinds to a halt with a light dusting of snow, the harbour froze hard enough to skate on.
Its beachside berth in Halifax Harbour seems peaceful enough, and Patrice shows me and three other clients where to snorkel on the reefs that were once a bit fuller of life, but still are home to reticent lobsters and various fish species that, taken together, look like a kindergarten paint set, including one spindly guy who wiggled like a rubbery paint brush.
