Biatora Epirotica
''Biatora epirotica'' is a species of corticolous (bark-dwelling) lichen in the family Ramalinaceae. Found in specific regions of the Balkans and Turkey, it was described as new to science in 2011 by lichenologists Christian Printzen and Toby Spribille. Taxonomy ''Biatora epirotica'' was first described by lichenologists Christian Printzen and Toby Spribille in 2011. The species epithet is derived from Epirus, the geographical region in the Balkans where most of the samples were collected. The type specimen was found by the second author in Epirus, Greece, on twigs of '' Abies borisii-regis''. Description The thallus of ''Biatora epirotica'' lacks a , is smooth to , and ranges in colour from beige to gray, often with a greenish tinge. The surface is matt, lacks soredia, and can grow up to in diameter. The lichen's is . Apothecia of ''Biatora epirotica'' are sessile, with a diameter of 0.3–0.6 mm, and a white to pale ochre . The lichen has 8-spored asci and (0–)3- ...

Biatora Pallens
''Biatora'' is a genus of lichens in the family Ramalinaceae. Originally circumscribed in 1817,Fries EM, Sandberg A. (1817). ''Lichenum dianome nova''. Lund. the genus consists of crustose and squamulose lichens with green algal photobionts, biatorine apothecia, colorless, simple to 3-septate ascospores, and bacilliform pycnospores. Description ''Biatora'' species are crustose lichens with a spreading () thallus that may appear thin and somewhat membranous in places. The surface is often cracked () and, in species that grow in association with mosses, may be or warted. The thallus is typically creamy white, dull green, glaucous green, or green-grey and lacks a distinct outer protective layer (). Some species produce soredia, small reproductive that facilitate dispersal. A , the initial fungal layer that some lichens form before developing a full thallus, is absent. The photosynthetic partner () is a alga, a group characterized by spherical to broadly ellipsoidal cells. The ...

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Tertiary Period
The Tertiary ( ) is an obsolete Period (geology), geologic period spanning 66 million to 2.6 or 1.8 million years ago. The period began with the extinction of the non-bird, avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic, Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene, Pliocene Epoch. The Tertiary has not been recognised by the International Commission on Stratigraphy (ICS) since the late 1980s, with the timespan of the Tertiary now being split in to the earlier Paleogene and the more recent Neogene periods, though the Tertiary continues to be used in some scientific publications. Historical use of the term The term Tertiary was first used by Giovanni Arduino (geologist), Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, t ...

Refugium (population Biology)
In biology, a refugium (plural: ''refugia'') is a location which supports an isolated or relict population of a once more widespread species. This isolation ( allopatry) can be due to climatic changes, geography, or human activities such as deforestation and overhunting. Present examples of refugial animal species are the mountain gorilla, isolated to specific mountains in central Africa, and the Australian sea lion, isolated to specific breeding beaches along the south-west coast of Australia, due to humans taking so many of their number as game. This resulting isolation, in many cases, can be seen as only a temporary state; however, some refugia may be longstanding, thereby having many endemic species, not found elsewhere, which survive as relict populations. The Indo-Pacific Warm Pool has been proposed to be a longstanding refugium, based on the discovery of the "living fossil" of a marine dinoflagellate called '' Dapsilidinium pastielsii'', currently found only in the ...

Black Sea
The Black Sea is a marginal sea, marginal Mediterranean sea (oceanography), mediterranean sea lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia (country), Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is Inflow (hydrology), supplied by major rivers, principally the Danube, Dnieper and Dniester. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea, not including the Sea of Azov, covers , has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end ...

Cyanolichen
Cyanolichens are lichens in which the fungal component () partners with cyanobacteria () for photosynthesis, rather than the green algae found in most other lichens. In some cyanolichens, known as forms, the cyanobacteria form an extensive throughout the main thallus, body of the lichen. Others, called lichens, contain both green algae and cyanobacteria, with the latter often confined to specialised wart-like structures known as cephalodia. This arrangement reflects the remarkable diversity within cyanolichens, which can feature filamentous or unicellular cyanobacteria, sometimes exhibiting multiple independent evolutionary origins across different fungal lineage (evolution), lineages. Beyond their diverse anatomy and taxonomy, cyanolichens perform vital ecological roles. Notably, they fix atmospheric nitrogen—converting it into forms that plants and other organisms can use. This nitrogen fixation is critical in both forest canopy (biology), canopies and arid-region biological ...

Quercus Coccifera
''Quercus coccifera'', the kermes oak or commonly known as Palestine oak, is an oak shrub or tree in section '' Ilex'' of the genus. It has many synonyms, including ''Quercus calliprinos''. It is native to the Mediterranean region and Northern African Maghreb, south to north from Morocco to France and west to east from Portugal to Cyprus and Turkey, crossing Spain, Italy, Libya, the Balkans, and Greece, including Crete. The Kermes oak was historically important as the food plant of '' Kermes'' scale insects, from which a red dye called crimson was obtained. The etymology of the specific name ''coccifera'' is related to the production of red cochineal (crimson) dye and derived from Latin coccum which was from Greek κόκκος, the kermes insect. The Latin -fera means 'bearer'. Description ''Quercus coccifera'' is usually a shrub less than high, rarely a small tree, reaching tall (with specimens recorded in Kouf, Libya).
