This broad geographical distribution, and the wide vertical range, in combination with the high level of specialisation, makes this group a perspective study object to learn about biogeographical and ecological aspects of reducing communities.
The Orchidaceae is probably the largest family of flowering plants with more than 27,000 species (Zotz 2013) and is the most diverse plant group (Swarts and Dixon 2009), with high levels of ecological specialisation for pollinators and mycorrhizal fungi (Bailarote et al. 2012).
The transition from traditional to modern society is accompanied by rapid increases in knowledge and high levels of occupational specialisation.
The high levels of achieved specialisation achieved led to an increase in the mix of patients coming outside the sphere of competence of the Local Health Authority (currently 50% of the users).
It may be noted, though, that the use of birth interventions is more widespread in societies with high levels of hospitalisation and specialisation and where private health services are prevalent [ 25, 28- 31].
This is partly related to the high levels of educational and occupational specialisation, and overall organisational complexity of modern societies, which requires people to move within and across borders to fulfil the desire to match qualifications and personal preferences with labour market and social opportunities.
In addition, the low vagility, high levels of endemism, strict habitat specialisation and sensitivity to environmental disturbance make triculine snails good indicators of near-pristine or long-term undisturbed habitats.
High levels of radiation.
