Crocidura Kornfeldi
''Crocidura kornfeldi'' is an extinct species of shrew that inhabited Central and Southern Europe between the Pliocene and Pleistocene. It is the first species of the widespread, extremely speciose genus ''Crocidura'' known with certainty to have colonized Europe. It is a widespread, well-documented species, with fossils known from Spain, Italy, Greece, Hungary, Romania, and Crimea. ''C. kornfeldi'' went extinct early in the Pleistocene, disappearing from the Iberian Peninsula around the boundary between the Early and Middle Pleistocene, possibly due to competition with newly-arriving species such as the modern greater white-toothed shrew (''C. russula''), lesser white-toothed shrew (''C. suaveolens''), and bicolored shrew The bicolored shrew or bicoloured white-toothed shrew (''Crocidura leucodon'') is a species of mammal in the family Soricidae. It is found in eastern, central and southern Europe and in western Asia. It is a nocturnal species and feeds on insect ... (''C. ...

Prehistoric Eulipotyphla
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relict (biology)
In biogeography and paleontology, a relict is a population or taxon of organisms that was more widespread or more diverse in the past. A relictual population is a population currently inhabiting a restricted area whose range was far wider during a previous geologic epoch. Similarly, a relictual taxon is a taxon (e.g. species or other lineage) which is the sole surviving representative of a formerly diverse group. Definition A relict (or relic) plant or animal is a taxon that persists as a remnant of what was once a diverse and widespread population. Relictualism occurs when a widespread habitat or range changes and a small area becomes cut off from the whole. A subset of the population is then confined to the available hospitable area, and survives there while the broader population either shrinks or evolves divergently. This phenomenon differs from endemism in that the range of the population was not always restricted to the local region. In other words, the species or group did ...

Cretan Shrew
The Cretan shrew (''Crocidura zimmermanni'') is a species of mammal in the family Soricidae. It is endemic to the island of Crete, Greece. Taxonomy and evolution ''Crocidura russula zimmermanni'' was first described as a subspecies of '' C. russula'' in 1953, and reconsidered as a full species by Vogel et al in 1986 on the basis of their distinct karyotype. The Cretan shrew has 34 pairs of chromosomes, while the other species examined in the study had 40. It may be a descendant of the extinct '' Crocidura kornfeldi'', the first ''Crocidura'' shrew to colonize Europe, which was distributed throughout central and southern Europe during the Pliocene and Pleistocene. It likely reached the island by rafting at some point in the early Pleistocene. It has remained extant on the island, while contemporaneous Cretan mammals such as mice, dwarf elephants, eight species of '' Candiacervus'' deer, and the Cretan otter went extinct. Unlike many small island mammals, it did not exhibit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicolored Shrew
The bicolored shrew or bicoloured white-toothed shrew (''Crocidura leucodon'') is a species of mammal in the family Soricidae. It is found in eastern, central and southern Europe and in western Asia. It is a nocturnal species and feeds on insects and other small creatures. Several litters of young are born during the warmer months of the year in a nest of dry grasses in a concealed location. Description The bicoloured white-toothed shrew has a head and body length of and a tail length of . It weighs about . The upperside is covered in short, dense dark brown fur and the underside is white, with a sharp dividing line between the two colours. The muzzle is long and pink, the teeth are white and the ears project through the hair. The tail is sparsely covered in slightly longer hairs. Young animals are rather paler in colour. These shrews often emit a shrill twittering chatter. Distribution and habitat The bicoloured white-toothed shrew is found in eastern, central and southern Eur ...

Lesser White-toothed Shrew
The lesser white-toothed shrew (''Crocidura suaveolens'') is a small species of shrew with a widespread distribution in Africa, Asia and Europe. Its preferred habitat is scrub and gardens and it feeds on insects, arachnids, worms, gastropods, newts and small rodents, though its diet usually varies according to the biotope where it lives. The closely related Asian lesser white-toothed shrew ('' Crocidura shantungensis'') was once included in this species, but is now considered to be a separate species. Like the common shrew, a female lesser white-toothed shrew and her young may form a "caravan" when foraging for food or seeking a place of safety; each shrew grips the tail of the shrew in front so that the group stays together. Distribution and habitat The lesser white-toothed shrew occurs widely from France and Portugal, in the west, across Europe and Asia to Japan and also in North Africa. It prefers dry ground, including scrub and gardens, and on the Isles of Scilly inhabits a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater White-toothed Shrew
The greater white-toothed shrew (''Crocidura russula'') is a small insectivorous mammal found in Europe and North Africa. It is the most common of the white-toothed shrews. This species is found along the Mediterranean Sea, Mediterranean, Netherlands, Belgium, Ireland, Germany and Portugal; in addition, the Osorio shrew of the Canary Islands, Canary island of Gran Canaria, originally described as a separate species (''Crocidura osorio''), was later discovered to be a population of introduced greater white-toothed shrew. Furthermore, a subspecies of the greater white-toothed shrew, ''Crocidura russula ibicensis'', is found on the Mediterranean island of Ibiza. In April 2008, the greater white-toothed shrew was discovered in Ireland as well, and in 2021 in England, discovered by a cat named Jeff. Its preferred habitats are grassland and woodland. It is slightly larger than the lesser white-toothed shrew but otherwise very similar and can often be distinguished only by close inspec ...

Competition (biology)
Competition is an Biological interaction, interaction between organisms or species in which both require one or more Resource (biological), resources that are in Limiting factor, limited supply (such as food, water, or Territory (animal), territory). Competition lowers the Fitness (biology), fitness of both organisms involved since the presence of one of the organisms always reduces the amount of the resource available to the other. In the study of community ecology, competition within and between members of a species is an important biological interaction. Competition is one of many interacting Biotic component, biotic and Abiotic component, abiotic factors that affect Community (ecology), community structure, species diversity, and population dynamics (shifts in a population over time). There are three major Mechanism (biology), mechanisms of competition: interference, exploitation, and apparent competition (in order from most direct to least direct). Interference and exploitat ...

Middle Pleistocene
The Chibanian, more widely known as the Middle Pleistocene (its previous informal name), is an Age (geology), age in the international geologic timescale or a Stage (stratigraphy), stage in chronostratigraphy, being a division of the Pleistocene Epoch within the ongoing Quaternary Period. The Chibanian name was officially ratified in January 2020. It is currently estimated to span the time between 0.7741 annum, Ma (774,100 years ago) and 0.129 Ma (129,000 years ago), also expressed as 774.1–129 ka. It includes the transition in palaeoanthropology from the Lower Paleolithic, Lower to the Middle Paleolithic over 300 ka. The Chibanian is preceded by the Calabrian (stage), Calabrian and succeeded by the Late Pleistocene. The beginning of the Chibanian is the Brunhes–Matuyama reversal, when the Earth's magnetic field last underwent reversal. Its end roughly coincides with the termination of the Penultimate Glacial Period and the onset of the Last Interglacial period (correspondin ...

Early Pleistocene
The Early Pleistocene is an unofficial epoch (geology), sub-epoch in the international geologic timescale in chronostratigraphy, representing the earliest division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently estimated to span the time between 2.580 ± 0.005 annum, Ma (million years ago) and 0.773 ± 0.005 Ma. The term Early Pleistocene applies to both the Gelasian, Gelasian Age and the Calabrian (stage), Calabrian Age. While the Gelasian and the Calabrian have officially been defined by the International Union of Geological Sciences (IUGS) to effectively constitute the Early Pleistocene, the succeeding Chibanian and Tarantian ages have yet to be ratified. These proposed ages are unofficially termed the Middle Pleistocene and Late Pleistocene respectively. The Chibanian provisionally spans time from 773 ka to 126 ka, and the Tarantian from then until the definitive end of the whole Pleistocene, c. 9700 BC in the 10th millennium BC. Notes {{Ge ...
