Topic: Species (biology)


  
 Species - Wikipedia, the free encyclopedia
Taxonomists are often referred to as "lumpers" or "splitters" by their colleagues, depending on their personal approach to recognizing differences or commonalities between organisms (see lumpers and splitters).
Obviously, when defining a species, the geographic circumstances become meaningful only if the populations groups in question are clearly different: if they are not consistently and reliably distinguishable from one another, then we have no grounds for believing that they might be different species.
Jean-Baptiste Lamarck suggested that an organism could pass on an acquired trait to its offspring, i.e., the giraffe's long neck was attributed to generations of giraffes stretching to reach the leaves of higher treetops (this well-known and simplistic example, however, does not do justice to the breadth and subtlety of Lamarck's ideas).

 Species
Hull (1965) contends that species have vague boundaries and that such vagueness is incompatible with the existence of species specific essences.
Supporters of the Biological Species Concept and related concepts believe that lineages of interbreeding sexual organisms are much more important in the evolution of life on this planet (Eldredge 1985).
For one, the relationship between an organism and its species is not a member/class relation but a part/whole relation.

 Folk biology and the anthropology of science
A notion of the species as a natural kind lingers in the philosophy of science and resolutely persists in psychology (Schwartz 1979, Rey 1983, Carey 1985, Gelman 1988, Keil 1995), which indicates that certain basic notions in science are as much hostage to the dictates of common sense as the other way around.
Folk biology, which is present in all cultures, and the science of biology, whose origins are particular to Western cultural tradition, have corresponding notions of living kinds.
Knowing not just the habits of particular species, but making taxonomic inferences about the habits and relationships of groups of biologically related species would be likely to increase the effectiveness (benefit) of such knowledge-based subsistence immeasurably, with little or no added investment (cost) in time or effort (trial-and-error learning).

 Evolution of the term 'Species'
Metabiology, i.e., the philosophy of biology, accompanying the development of the theory of the evolution of life was therefore formulated mainly by biologists such as Ernst Haeckel or by interested physicians such as Ludwig Büchner or Hermann Helmholtz.
The old species concept, based on the metaphysical concept of an essence, is so fundamentally different from the biological concept of a reproductively isolated population that a gradual changeover from one into the other was not possible.
The species essence was considered to be the unchanging concept in the mind of God about the ideal form of the members of a biological population.

 The Biology Of Annelids
This technique shows many details of annelid functional biology: food being moved along the intestine by peristaltic contractions; the circulatory system including capillary beds where oxygen is picked up (worms breath through their skins); and excretory organs that act as miniature kidneys to remove urea.
Their elongate, segmented body plan and other body features have allowed annelids to specialize at burrowing through substrates, and to radiate into other ecological niches.
Featuring live photography of a diversity of annelid worms showing their behavior, structures and classification into three classes.

 Marine biology - Wikipedia, the free encyclopedia
Other subfields study the physical effects of continual immersion in sea water and the ocean in general, adaptation to a salty environment, and the affects of changing various oceanic properties on marine life.
Marine biologists are trying to complete the mapping of underwater species with the help of modern techniques.
It is also becoming understood that the well-being of marine organisms and other organisms are linked in very fundamental ways.

 Invasive Species: The Biology - Part 4
The biology will be presented in such a way that everyone else can but accept it and any questions will be either ignored, or treated as the ravings of the ignorant.
As with Endangered Species, a cadre of University researchers will arise to make claims of what "needs" to be done regarding cheatgrass or day lilies to not only eradicate them, but to keep them eradicated.
There is no such thing as "native," there are only some species that have been somewhere longer than others.

 The Open Door Web Site : Biology : Introduced Species
Sometimes the introduction of species is intentional and beneficial for humans.
One group of organisms which people are especially concerned about are micro-organisms.
Plant species used in agriculture, for example, have been deliberately introduced to new areas by humans.

 Endangered Species Act / Biology
To facilitate compliance with Section 7, a Biological Assessment (BA) is conducted for bridge related activities for the purpose of identifying "listed" species which are likely to be affected by the activity.
In addition, WSDOT is in the process of developing a Programmatic Biological Assessment that will provide a simplified BA process for many types of transportation related activities.
There is little documentation available that describe and verify the impact associated with bridge related activities upon salmonids because the "listing" of salmonids is a fairly recent event in Washington State.

 Biology News: Species list reaches half-million mark
The catalogue is useful in any situation where researchers want to keep track of living organisms, says Kirk.
Ultimately, biologists need a catalogue that is full of information about each species, rather than a mere directory of names, he says.
For example, a definitive list of all the species within a particular genus can help with evolutionary studies.

 Preserving Biodiversity through Genetics
Work is in progress to develop related methods to identify tiger bones in Asian medicines.
Many species are difficult to capture, or become stressed by the process.
Information regarding the extent of gene flow among populations is critical to determine whether a species requires translocation of individuals to prevent inbreeding and loss of genetic diversity.

 AllRefer.com - species (Biology, General) - Encyclopedia
The species marks the boundary between populations of organisms rather than between individuals.
The latter term refers to that collection of characteristics whose combination is unique in the species, although each individual of the group may not display every single one of the characteristics (see genetics).
species, in biology, a category of classification, the original and still the basic unit in the demarcation of plant and animal types.

 biology - Precocial
Precociality is of course also found in other groups.
Additionally, most precocial chicks lack the ability to control their own body temperatures (thermoregulation), and they depend on the attending parent(s) to provide an outside source of heat for a short period of time.
Familiar examples of precocial mammals are most ungulates, the guinea pig, and most species of hare.

 Biology News: Species mix across Panama Canal
Every species interacts with other species in the group, for example by forming a predator-prey relationship, or forging a mutual bond such as that of corals with algae.
According to the 'niche' theory of ecosystems, every species within a community, be it river or rainforest, has a well-defined role in life.
This is at odds with many experts' belief that intruders upset the delicate balance of ecosystems.

 Plant Species Biology Aims & Scope
Plant Species Biology aims at communicating and exchanging knowledge and ideas on plant species and their biological aspects including life histories, population dynamics, molecular biosystematics, co-evolutionary networks among plants and other organisms, and mechanisms of speciation.
Plant Species Biology is an international journal publishing peer-reviewed original researches, notes and comments, and reviews in the field of evolutionary biology in plants.
This knowledge is essential for modern conservation biology, which has a key role in today's preservation of endangered biodiversity.

 Invasion Biology Introduced Species Summary Project - Columbia University
The poison does not protect the toad against all predators, for most snakes and birds seem to be unaffected and humans tend to only get skin irritation, but it is fatal to small animals as well as many domestic cats and dogs.
Their extremely prolific reproduction, effective adult defense, and ability to thrive in areas where native species are stressed, make the B.
That is not to say that are NOT considered a problem, but it has not yet been demonstrated to be quickly causing the decline of the biodiversity of the invaded habitat.

 Biology: endemic species
I am unaware of recent extinctions on islands but even the slightest change of the environment on an island can cause death because the conditions under which the animals exist are limited and there is no input of new DNA due to the isolation Again returning to the Galapagos.
Almost all animals there are found only there.
Why do you suppose there are so many endemic species on islands?

 Cothran Biology Thesis Species List
Not only were some species of trees more susceptable to vine infestation, but large trees were more likely to have vines on them than would be predicted from their size alone.
Then, analysis of the data was performed, showing that these vines do not occurr on tree species randomly.
This work involved the investigation of the population structure of woody vines in a mature mixed mesophytic forest on the Western slope of a mesa dissected from the edge of the Cumberland Plateau, in Madison County AL.
