The city of Trikala is located in the region of Thessaly. Lithaios river, a tributary of Pineios, is crossing the city. It's waters are used for irrigation of about 14,000 acres in local areas.

Polution problems

tolisva2 — 2019-02-11 08:16:59 UTC

In the area of the river basin there is a considerable number of industrial-craft units (milk factories, dairies, livestock farms). There are also hotel units, the hospital, garages, washing machines and car paint shops, the majority of which do not undergo any treatment . This situation is likely to lead to the illegal disposal of both waste water and the "sludge" created in the collection tanks, as evidenced by the abundance of dead fish on the banks, as well as the color of the water and the bad smell of the river.

The treated urban waste water of the city's biological purification collects about 20% of all sewage.

The goals of the museum are:

The creation, maintenance and promotion of member clubs that will contribute to the study and preservation of our natural heritage.
The shaping of environmental awareness through the validity and diffusion of knowledge, guaranteeing the cooperation with renowned scientific institutions, universities and museum educators.
The utilization of scientific collections and the contribution to studies on natural environment, particularly to the region of Pindus.
The development of educational and publishing activities and the creation of a data bank about the exhibited species.
The organization of exhibitions, events and seminars on the environment, and activities that bring people in contact with nature and complexity of its operations.

1. Grey wolf - Deer
Gray wolf diet is predominantly composed of large and medium-sized wild ungulates.

2. Fox - lizards
Foxes are omnivores. The diet of foxes is largely made up of small vertebrates such as reptiles.

Parasitic organisms

1. Cordyceps militaris is a species of ascomycete fungi. Most Cordyceps species are endoparasitoids, parasitic mainly on insects and other arthropods a few are parasitic on other fungi.
When a Cordyceps fungus attacks a host, the mycelium invades and eventually replaces the host tissue, while the elongated fruit body (ascocarp) may be cylindrical, branched, or of complex shape. The ascocarp bears many small, flask-shaped perithecia containing asci. These, in turn, contain thread-like ascospores, which usually break into fragments and are presumably infective.

Parasitic organisms (2)

2. Leeches are segmented parasitic or predatory worms that belong to the phylum Annelida and comprise the subclass Hirudinea. They are closely related to the oligochaetes, which include the earthworms, and like them have soft, muscular, segmented bodies that can lengthen and contract. Both groups are hermaphrodites and have a clitellum, but leeches typically differ from the oligochaetes in having suckers at both ends and in having external annulations that do not correspond with their internal segmentation. The body is relatively solid, and the spacious body cavity found in other annelids, the coelom, is reduced to small channels.

Endagered species

The Egyptian vulture (Neophron percnopterus), also called the white scavenger vulture or pharaoh's chicken, is a small Old World vulture and the only member of the genus Neophron. It is widely distributed; the Egyptian vulture is found from the Iberian Peninsula and North Africa to India. The contrasting underwing pattern and wedge-shaped tail make it distinctive in flight as it soars in thermals during the warmer parts of the day. Egyptian vultures feed mainly on carrion but are opportunistic and will prey on small mammals, birds, and reptiles. They also feed on the eggs of other birds, breaking larger ones by tossing a large pebble onto them.

The use of tools is rare in birds and apart from the use of a pebble as a hammer, Egyptian vultures also use twigs to roll up wool for use in their nest. Egyptian vultures that breed in the temperate regions migrate south in winter while tropical populations are relatively sedentary. Populations of this species declined in the 20th century and some island populations are endangered by hunting, accidental poisoning, and collision with power lines. https://en.wikipedia.org/wiki/Egyptian_vulture
