One very typical example is the different species of deer that exist. Herds of deer go hand to hand with packs of wolves. ]]> 2019-01-26 07:25:38 UTC https://padlet.com/katsogridakis_stelios/ilg6f6sseg2c/wish/324551348 Bonelli’s eagles, rabbits and partridges katsogridakis_stelios https://padlet.com/katsogridakis_stelios/ilg6f6sseg2c/wish/324551355 Bonelli’s eagle is a large bird of prey that lives around the Mediterranean and eastwards in Asia in Iran, Arabia, Oman, Turkmenistan, India, southern China, Pakistan. In Greece more than 50% of it lives in Islands. Its main diet is rabbits and partridges.

The last almost 30 years has invaded the Mediterranean. Palm trees are it favorable host. In Crete where I come from you can see its impact all around the island. It is estimated that it has affected 4000 palm tree in city parks and private residents (Mine included!). From the 4,000 trees affected by the beetle in Crete, two belong to the species Washingtonia robusta, two in the endemic palm tree, P.theophrasti, a young one-meter high and the rest belong to the Canary Phoenix canariensis palm.

That has been classified as a species of Community Interest in need of strict protection by the European Habitats Directive and as an Endangered Species by the Protocol Concerning Specially Protected Areas and Biological Diversity in the Mediterranean from the Barcelona Convention. A study carried out by the Balearic Oceanographic Center of the Spanish Institute of Oceanography has concluded that in most of the Spanish Mediterranean coast there are high mortality rates, up to 100% in some points, especially in the populations of Andalusia, Murcia, Valencia Community and Balearic Islands.

The wolf’s ecological niche is to keep its prey’s numbers from overpopulating. ]]> 2019-01-26 07:33:11 UTC https://padlet.com/katsogridakis_stelios/ilg6f6sseg2c/wish/324551698 Brown bear katsogridakis_stelios https://padlet.com/katsogridakis_stelios/ilg6f6sseg2c/wish/324551760 According to this study Brown bears (Ursus arctos) as ecological engineers: the prospective role of trees damaged by bears in forest ecosystems Brown bears by foraging on hardwood, create new niches for resident biota, especially for saproxylic insects and woodpeckers. In addition, field observations showed that trees wounded by bears can be used for different purposes by other organisms Fungi, amphibians, and mammals are the groups that also use wounded trees for feeding, breeding, or concealment. ]]> 2019-01-26 07:35:31 UTC https://padlet.com/katsogridakis_stelios/ilg6f6sseg2c/wish/324551760 Niche Partitioning between European avian scavengers katsogridakis_stelios https://padlet.com/katsogridakis_stelios/ilg6f6sseg2c/wish/324551848 According to this study Behavioral coexistence and feeding efficiency drive niche partitioning in European avian scavengers Morphology determines carrying ability of carrion: species with more pointed beaks and a greater prehensile ability took more pieces away. Facultative scavengers preferred more abundant and soft parts of the carcasses as opposed to specialized vultures.

Paedomorphs focused mainly on pelagic crustaceans, whereas metamorphs foraged more on terrestrial invertebrates at the water surface. Two populations of the Greek Alpine newt Triturus alpestris veluchiensis living in fishless alpine lakes were studied. One is located in the Tymphi Mountains and the other in the Smolikas mountains.
