Only the timid wild goat (Capra aegarus creticus), known as agrími or kri-kri in Greek, is still native to some of the uninhabited islands off the coast and in Samaria Gorge. There, however, they are increasingly mingling with the domestic goats, because some of the shepherds from the neighbouring regions drive their goats into the gorge for the purpose of adding genetic diversity, and the odd domesticated billy is sometimes among them. The wild goat population is estimated at approximately 2500 animals. You are sure to spot them in Chania public gardens.]]> 2019-01-08 19:12:08 UTC https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/318508021 elpidagalanaki https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/318514187 Acrocephalus arundinaceus.

Varroa destructor  is an external parasitic mite that attacks the honey bees Apis cerana and Apis mellifera. The disease caused by the mites is called varroosis. The Varroa mite can only reproduce in a honey bee colony. It attaches to the body of the bee and weakens the bee by sucking. In this process, RNA viruses such as the deformed wing virus(DWV) spread to bees. A significant mite infestation will lead to the death of a honey bee colony, usually in the late autumn through early spring. The Varroa mite is the parasite with the most considered to be one of multiple stress factors contributing to the higher levels of bee losses around the world.

They are a diverse animal phylum inhabiting a broad range of environments. Taxonomically, they are classified along with insects in the clade Ecdysozoa. Nematodes have successfully adapted to nearly every ecosystem: from marine to fresh water, soils, from the polar regions to the tropics, as well as the highest to the lowest of elevations, where they often outnumber other animals in both individual and species counts, and are found in locations as diverse as mountains, deserts, and oceanic trenches. Depending on the species, a nematode may be beneficial or detrimental to plant health. From agricultural perspectives, the two categories of nematodes are the predatory ones, which is garden pests such as cutworms and corn earthworm moths, and the pest nematodes, such as the root-knot nematode, which attack plants, and those that act as vectors spreading plant viruses between crop plants. ]]> 2019-01-08 20:05:45 UTC https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/318541319 elpidagalanaki https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/318612127 Intra-population niche differences in generalist foragers have captured the interest of ecologists, because such individuality can have important ecological and evolutionary implications. Few researchers have investigated how these differences affect the relationships among ecologically similar, sympatric species. Using stable isotopes, stomach contents, morphology and habitat preference, we examined niche partitioning within a group of five anurans and determined whether variation within species could facilitate resource partitioning. Species partitioned their niches by trophic level and by foraging habitat. However, there was considerable intraspecific variation in trophic level, with larger individuals generally feeding at higher trophic levels. For species at intermediate trophic levels, smaller individuals overlapped in trophic level with individuals of smaller species and larger individuals overlapped with the smallest individuals from larger species. Species varied in carbon isotopes; species with enriched carbon isotope ratios foraged farther from ponds, whereas species with depleted carbon isotope values foraged closer to ponds. Our study shows that these species partition their niches by feeding at different trophic levels and foraging at different distances from ponds. The intraspecific variation in trophic level decreased the number of individuals from each species that overlapped in trophic level with individuals from other species, which can facilitate species coexistence.]]> 2019-01-09 00:31:08 UTC https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/318612127 elpidagalanaki https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/318612662 2019-01-09 00:35:29 UTC https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/318612662 elpidagalanaki https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/318614315 An example of niche partitioning, several anole lizards in the Caribbean islands share common food needs—mainly insects.

Their natural predators include large birds of prey,  canids and felids. They rely on high-speed endurance running to escape predation, having long, powerful limbs and large nostrils. The European hare is listed as being of least concern by the International Union for Conservation of Nature because it has a wide range and is moderately abundant. However, populations have been declining in mainland Europe since the 1960s, at least partly due to changes in farming practices. The hare has been hunted across Europe for centuries, with more than five million being shot each year; in Britain, it has traditionally been hunted by beagling and hare coursing , but these field sportsare now illegal]]> 2019-01-09 19:59:01 UTC https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/318991439 elpidagalanaki https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/319002729 A bumblebee is any of over 250 species in the genus Bombus, part of Apidae, one of the bee families.
Bumblebees are important pollinators of both crops and wildflowers.  Bumblebees are increasingly cultured for agricultural use as pollinators, among other reasons because they can pollinate plants such as tomato in greenhouses by buzz pollination whereas other pollinators cannot.
Bumblebee species are declining in Europe, North America, and Asia due to a number of factors, including land-use change that reduces their food plants. A major impact on bumblebees was caused by the mechanisation of agriculture, accelerated by the urgent need to increase food production during the Second World War. Also a significant increase in pesticide and fertilizer use associated with the industrialization of agriculture has had adverse effects on the genus Bombus. Bumblebees are in danger in many developed countries due to habitat destruction and collateral pesticide damage. The European Food Safety Authority ruled that three neonicotinoid pesticides (clothianidin, imidacloprid, and thiamethoxam) presented a high risk for bees.  Some bumblebees native to North America are also vanishing, such as Bombus balteatus, Bombus terricola,Bombus affinis, and Bombus occidentalis, and one, Bombus franklini, may be extinct. In South America, Bombus bellicosus was extirpated in the northern limit of its distribution range, probably due to intense land use and climate change effects.]]> 2019-01-09 20:21:37 UTC https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/319002729 elpidagalanaki https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/319005156 2019-01-09 20:26:56 UTC https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/319005156 elpidagalanaki https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/319005563 A preliminary inventory of the alien flora of Crete (Greece)]]> 2019-01-09 20:27:54 UTC https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/319005563 elpidagalanaki https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/319006787 2019-01-09 20:30:54 UTC https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/319006787 elpidagalanaki https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/319007643  Climate change impacts in Greece in the near future ]]> 2019-01-09 20:33:08 UTC https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/319007643 elpidagalanaki https://padlet.com/elpidagalanaki/elpida_kal_G7/wish/319008995 Annual temperature over the period 1961–1990 showed a trend of statistically significant warming over land in south-east Europe of approximately 0.4–0.6 °C per decade. In the middle of the ’50s a cooling period started in northern Greece and progressively extended also in the southern regions of the country where it started to be detected in the beginning of the’70s. The lowest average annual temperatures in Greece occurred in the decade of 1970 up to the beginning of 1980, due mainly to the very cold summers and autumns. However, during the last years of the ’90s (while a little earlier in some meteorological stations), a progressive increase of temperature was observed. … This seems to be due to a more intensive warming during the summer period. In Greece, as it was also the case of Spain, the frequency of heat waves in the ’90s was about three times higher than the one of the three previous decades. However, there are no signs of a similar reverse trend in the frequency of cold extremes. The data from both stations of Athens and Corfu present statistical important increasing trends with respect to the duration of heat waves, during the summer period as well as on annual basis, while the occurrence of cooling waves during winter as well as on annual basis becomes much less frequent. The time series from the other stations do not show a certain trend or they show negative trends with respect to the duration of heat waves. In the eastern Mediterranean, the intensity, length and number of heat waves have increased by a factor of six to eight since the 1960s

Data reduction analyses have been applied to tackle the problem of highly correlated indices, but valid landscape predictors for fine scale Mediterranean forest-mosaics are still missing. Therefore, we analyzed the landscape structure of Dadia National Park, Greece, a Mediterranean forest landscape of high biodiversity, characterized by pine, oak and mixed woodland. By distinguishing nine land cover classes, 119 variables were computed and factor analysis was applied to detect the statistical dimensions of landscape structure and to define a core set of representative metrics. At landscape level, diversity of habitats, fragmentation and patch shape and at class level dominance of mixed forest and the gradient from one pure forest type to another turned out to be the crucial factors across three different scales. Mapping the encountered dimensions and the representative metrics, we detected that the pattern of landscape structure in Dadia National Park was related to dominating habitat types, land use, and level of protection. The evaluated set of metrics will be useful in establishing a landscape monitoring program, to detect the local drivers of biodiversity, and to improve management decisions in Dadia NP and similar mosaic-landscapes.
