A species of wader in the Haematopodidae family. It is endemic to New Zealand. The Maori name is torea-pango. They are also known as 'red bills'. "Variable" refers to the frontal plumage, which ranges from pied through mottled to all black. They are polymorphic meaning they have different genetic variants. Blacker birds are more common in the south. All Stewart Island variable oystercatchers are black. They have pink legs, an orange eye ring and red beaks. They are often seen in pairs on the coast all around New Zealand. During breeding, the pair will defend their territory, sometimes aggressively. Once mated pairs rarely divorce. After breeding they may be seen within flocks, or on the edges of flocks, of black and white South Island Pied Oystercatcher (SIPO) which also have vivid orange beaks. After breeding they may even form small flocks of their own. Males are around 678 grams and females slightly larger at around 724 grams. Variables can be identified as they are slightly larger than the SIPO - SIPO are around 550 grams. Occasionally totally black but if they are pied (black and white) they can be easily confused with SIPO. The variable species has less definition between the black and the white area, as well as a mottled band on the leading edges of the underwing. Variables also have a smaller white rump patch which is only a band across the base of the tail rather than a wide wedge shape reaching up to the middle of the back as in the SIPO. When mottled they are sometimes called 'smudgies'. They feed on molluscs, crabs and marine worms. After heavy rain, they sometime go inland in search of earthworms. They can open a shellfish by either hammering a hole in it or getting the bill between the two shells (of a bivalve) and twisting them apart. They breed in North Island, South Island, Stewart Island, and Chatham Islands. They do not breed inland or beside rivers although the SIPO does. They nest on the shore between rocks or on sand dunes by making a scrape out of the sand or shingle, sometimes lined with some seaweed. When in flight they make a high pitched 'kleep kleep' sound. They usually lay 2-3 eggs but they can lay up to 5. The eggs are typically stone coloured with small brown patches all over. Eggs hatch in 25-32 days. Chicks are well camouflaged by their colour and can fly in about 6 weeks. The bird lives up to about 27 years.

Daucus carota (wild carrot) "This is a polymorphic plant with a branching stem and deeply divided leaves. The umbels are large with a multitude of rays and the flowers white or purple, always with dark purple at the center. After flowering, the umbel closes to form a ball. The plant, which has a tuberous rhizome, is the progenitor of the cultivated carrot. Found in fields and on roadsides."

Comment: Helleborus niger is another plant, which fuels my admiration year after year. Its large, up to 10 cm in diameter, snow-white flowers (when young) with their unusual structure (large white 'petals' are actually sepals!) are very beautifully shaped. But they are not only white! Many other shades from yellow, greenish, vividly pink, wine-red, to purple can be found during their growth. The first flowers already appear in earl winter, sometimes even in late November, if the weather allows and bloom well in April, even in May on cool places with lot of snow during the winter. The plant is a floral element of south and east Alps It is widely exploited in horticulture. Helleborus niger is especially valued in Japan, where Helleborus societies are establish, which organize trips to European places where displays of wild growing plants can be admired.
In west Slovenian in Upper Soča river valley and elsewhere Helleborus niger is too common plant to be truly admired. In February and March there are zillions of plants flowering everywhere, in forests, on grassland and especially along wood edges. On many places they represent the most dominant flowering plant not only during late winter but also in early spring.
How many species genus Helleborus comprise is still an open question. The number varies from 5 to 20, depending on to whom you trust. Many of them are extremely polymorphic and any kind of intermediate forms can be found.

The most widespread species of Ischnura in the New World. Most of the USA, plus Mexico, Antilles, south to Chile and Hawaii (where it was introduced in 1973). Larvae in most wetland habitats, but only in coastal plain in ne USA. Preferred habitat includes heavily vegetated ponds, lakes, marshes and slow reaches of streams exposed to sunlight including brackish waters.
Found spring to fall, all year in much of Florida.
A polymorphic species, males will have either a bright green thorax or a bluish thorax, females have three forms; orange, olive (which this one is), or are male-like in coloration. There is an apparent lack of color preference by males, but there are selective advantages and disadvantages of various color forms in populations.
Both sexes will remain close to the water and although males are not territorial, females are known to be highly predaceous and often cannibalistic. Males often do not release females from the wheel position for several hours, and sometimes as many as seven, to secure their genetic contribution.

Māmane is a species of flowering plant in the pea and bean family, Fabaceae, that is endemic to Hawaii. It is highly polymorphic, growing as a shrub or tree, and able to reach a height a height of 15 m (49 ft) in tree form. Yellow flowers are produced in winter and spring.
It inhabits low shrublands, high shrublands, dry forests, mixed mesic forests, and, rarely, wet forests. It can grow at elevations of 30–2,900 m (98–9,500 ft), being limited by the tree line. Māmane is most common and grows the tallest in montane dry forests at elevations of 1,220–2,440 m (4,000–8,000 ft). Māmane is essential for the endangered palila (Loxioides bailleui), which feeds almost exclusively on the plants' immature seeds when these are in season. It also nests in the māmane branches. Caterpillars of Cydia moths also eat the māmane's seeds, and in turn are being eaten by the palila. Both the bird and the larvae utilize the embryo only, leaving the seed coat untouched. To other animals, māmane seeds are highly poisonous. House Finches die within minutes after eating the seeds. The māmane employs a two-layered biochemical defence system: The seed coats contain some 4% phenolic compounds, which give them a vile taste. They are also somewhat toxic and have a high fibre content. Seed predators trying to eat the seeds will probably not killed but at least have a nasty experience. Should a predator be able to penetrate the seed coat, the embryo contains deadly quantities (>4% of dry weight) of quinolizidine alkaloids. The palila and the moths, however, have evolved the ability to deal with the poisonous compounds.
"A polymorphic plant which often forms dense stands along the sides of the roads. The stem is slender, erect, and has leaves with three elongated, lanceolate and long-stalked leaflets. The flowers are blue-violet with hairy calyces in almost round heads which have a very long flower stalk and grow in the axils of the leaves. The plant is easily recognized by the characteristic smell of tar which it emits. Common on roadsides, in ditches, and in fallow fields."

Hyles euphorbiae euphorbiae (L.), (Sphingidae)
Common name: Spurge Hawkmoth
Major hostplants: Herbaceous species of Euphorbia, especially E. paralias, E. cyparissias and in southern Europe, E. characias
Larva in this photograph is feeding on Euphorbia paralias.
Taxonomic note: Within the Hyles genus there is a complex of species, subspecies and forms, all closely related to Hyles euphorbiae and all of which are highly polymorphic with an amazing variety of colour forms, some geographic in nature, others environmental. The Hyles euphorbiae complex is rather difficult to classify for it would seem to be in the process of diverging into a number of species.

Be awed ~ aim ~ shoot and sometimes there are hidden surprises! Found this gem while looking for other photos to morph into an artistic project. From More About"... The water lily is the first link. The snail eats the water lily. The crayfish eats the snail. The bullfrog eats the crayfish. The Northern water snake, which is the last link, eats the bullfrog. As each link in the food chain gets eaten, it passes some of the energy stored in its body to the next link in the chain."

Doris’ Longwing, Heliconius (Laparus) doris is an odd member of the genus with differently shaped wings and gregarious larvae. It occurs from sea level to 1,800 m in forest clearings. It ranges from Central America to the Amazon. Usually individuals fly rapidly (unusual for most longwings) and in the middle story. Heliconius doris populations are polymorphic in parts of the species distribution, with blue, red or green coloration
at the base of the dorsal hindwing.
Gene-Tree, Species-Tree Roconciliation:
This figure shows an example of the history of three Rare Genomic Changes (RGC). The analysis of sequence data such as point mutations at few loci can be misleading because of homoplasy. Only synapomorphies permit the reconstruction of phylogenetic relationships of taxa such as "Darwinian species". For example, retroelement insertions in a specific genomic site are always synapomorphic after a subsequent mutation while the empty insertion site is always ancestral, i.e. plesiomorphic. Evolution can be directly observed based on the strictly oriented time arrow.
Explanation:
Homoplasy is a similarity that is not inherited from a common ancestor, but obtained independently in two lineages, either by convergence or by reversion.
T1 (time 1 in the past): population genetics: the informative characters are the polymorphic, not fixed alleles.
T2 (time 2 more recent): population genetics/phylogenetics: the informative characters are the polymorphic, fixed and not fixed RGC-alleles.
T3 (present time): phylogenetics: the informative characters are the polymorphic, fixed RGC-alleles.

Arctic Skua - Stencorarius parasiticus.
This is a polymorphic bird with two colour phases. The lighter phase bird has a dark patch on the upper breast, and is more common in the far north. This one seen in the Hornsund at 77 deg north, under the chaotic Hornbreen snout. A lot of kittiwakes, glaucous gulls and arctic terns here.
So a lot of noise as they continually torment each other and compete for position under the ice cliffs where the mineral deposits, shallow water and relative warmth in the water enable fast growth of the krill species. I didn’t observe any gulls taking fish sprats here.
The Arctic Tern is present throughout the Palearctic from above 80 deg north to 57 deg north - which is where I live. Occasionally seen here, - often seen on Handa, Orkney, Shetland and St Kilda.
They take half fledged chicks from auk, kittiwake and tern colonies.
They prefer a dry nesting spot surrounded by water or boggy ground. Intruders will experience how strongly they defend the nest and young. First they feign injury and wing drag, inviting the intruder to follow. If this does not work they will attack the head from behind, sufficiently aggressively to cause scratches and bleeding . A good defence against this is to walk with a walking pole fully extended upwards, strapped to the side of a rucksack. Better still is to avoid disturbing their nesting grounds altogether.
They probably mate for life, both parents care for the young.
Outside of the breeding season they are piratical upon other birds forcing gulls and terns to disgorge their catch, which they will often take mid air before it hits the sea.

Pictured at Matiu/Somes Island, Wellington, New Zealand. The variable oystercatcher is a species of wader in the Haematopodidae family. It is endemic to New Zealand. The Maori name is torea-pango. They are also known as 'red bills'.
"Variable" refers to the frontal plumage, which ranges from pied through mottled to all black. They are polymorphic meaning they have different genetic variants. Blacker birds are more common in the south. All Stewart Island variable oystercatchers are black. The have pink legs, an orange eye ring and red beaks. They are often seen in pairs on the coast all around New Zealand. During breeding, the pair will defend their territory, sometimes aggressively. Once mated pairs rarely divorce. After breeding they may be seen within flocks, or on the edges of flocks, of black and white South Island Pied Oystercatcher (SIPO) which also have vivid orange beaks. After breeding they may even form small flocks of their own. Males are around 678 grams and females slightly larger at around 724 grams. Variables can be identified as they are slightly larger than the SIPO - SIPO are around 550 grams. Occasionally totally black but if they are pied (black and white) they can be easily confused with SIPO. The variable species has less definition between the black and the white area, as well as a mottled band on the leading edges of the underwing. Variables also have a smaller white rump patch which is only a band across the base of the tail rather than a wide wedge shape reaching up to the middle of the back as in the SIPO. When mottled they are sometimes called 'smudgies'. They feed on molluscs, crabs and marine worms. After heavy rain, they sometime go inland in search of earthworms. They can open a shellfish by either hammering a hole in it or getting the bill between the two shells (of a bivalve) and twisting them apart. They breed in North Island, South Island, Stewart Island, and Chatham Islands. They do not breed inland or beside rivers although the SIPO does. They nest on the shore between rocks or on sand dunes by making a scrape out of the sand or shingle, sometimes lined with some seaweed. When in flight they make a high pitched 'kleep kleep' sound. They usually lay 2-3 eggs but they can lay up to 5. The eggs are typically stone coloured with small brown patches all over. Eggs hatch in 25-32 days. Chicks are well camouflaged by their colour and can fly in about 6 weeks. The bird lives up to about 27 years.

They usually lay 2-3 eggs but they can lay up to 5. The eggs are typically stone coloured with small brown patches all over. Eggs hatch in 25-32 days. Chicks are well camouflaged by their colour and can fly in about 6 weeks. The bird lives up to about 27 years.
Presence of oridonin when mapped onto a molecular phylogeny of Isodon.Phylograms represent strict consensus of most parsimonious (MP) trees, using sequence data from the chloroplast (rps16, trnL-trnF; strict consensus of 140 MP trees) and nucleus (ITS; strict consensus of 390 MP trees). Presence of oridonin is indicated by dark colored branches. Taxa reported polymorphic for oridonin production (some populations produce oridonin, others do not) are shown with an asterisk. Samples newly sequenced for this study are shown with gray shading. Parsimony bootstrap (BS) values are shown above branches, Bayesian posterior probabilities (PP) are shown below branches. Support values are shown only for branches with BS>75. Outgroup taxon (C. xanthanthus) used for ancestral state construction not shown.
The grove snail or brown-lipped snail (Cepaea nemoralis)
Easy to confuse with the similar Capaea hortensis - The White-lipped Snail. When the identity of an adult individual is questionable, and it is necessary to distinguish the two species, a dissection can be used in order to examine the anatomy: the structure of the love dart is quite different in the two species, as are the vaginal mucus glands.
Photographed on the Wellington Coast north of Plimmerton.
A species of wader in the Haematopodidae family. It is endemic to New Zealand. The Maori name is torea-pango. They are also known as 'red bills'. "Variable" refers to the frontal plumage, which ranges from pied through mottled to all black. They are polymorphic meaning they have different genetic variants. Blacker birds are more common in the south. All Stewart Island variable oystercatchers are black. They have pink legs, an orange eye ring and red beaks. They are often seen in pairs on the coast all around New Zealand. During breeding, the pair will defend their territory, sometimes aggressively. Once mated pairs rarely divorce. After breeding they may be seen within flocks, or on the edges of flocks, of black and white South Island Pied Oystercatcher (SIPO) which also have vivid orange beaks. After breeding they may even form small flocks of their own. Males are around 678 grams and females slightly larger at around 724 grams. Variables can be identified as they are slightly larger than the SIPO - SIPO are around 550 grams. Occasionally totally black but if they are pied (black and white) they can be easily confused with SIPO. The variable species has less definition between the black and the white area, as well as a mottled band on the leading edges of the underwing. Variables also have a smaller white rump patch which is only a band across the base of the tail rather than a wide wedge shape reaching up to the middle of the back as in the SIPO. When mottled they are sometimes called 'smudgies'. They feed on molluscs, crabs and marine worms. After heavy rain, they sometime go inland in search of earthworms. They can open a shellfish by either hammering a hole in it or getting the bill between the two shells (of a bivalve) and twisting them apart. They breed in North Island, South Island, Stewart Island, and Chatham Islands. They do not breed inland or beside rivers although the SIPO does. They nest on the shore between rocks or on sand dunes by making a scrape out of the sand or shingle, sometimes lined with some seaweed. When in flight they make a high pitched 'kleep kleep' sound. They usually lay 2-3 eggs but they can lay up to 5. The eggs are typically stone coloured with small brown patches all over. Eggs hatch in 25-32 days. Chicks are well camouflaged by their colour and can fly in about 6 weeks. The bird lives up to about 27 years.
I was a biology geek in school and we a good few trips counting snails , drawing diagrams ...they probably get to play with digi cameras now Sigh...... but if you care a brief and overly simply bio lesson ......all these snail in pictures are the same species Cepaea nemoralis it gets studied a lot in biology cos its polymorphic (within the species it has many physical forms ). On grassland you tend to find just the pale ones, cos the darker snails are very visible to feeding birds and therefore fail to pass on their genes to the next generation . But you get wildly differing types in structually diverse environments like this wood the banding good camouflage for the "stripeys" hanging out on the knots while the "pale snails" prefer the leaves .
Phylogenetic trees based on FAFLP and multigene sequence analyses. A. Polymorphic fragments were subjected to allele calling in Genotyper (Applied Biosystems, USA) and allele scoring was recorded in a binary format.This binary data were used to construct a phylogenetic tree (please see methods). B. Phylogenetic tree constructed based on consensus multigene alignment which involved concatenation of individual gene sequences corresponding to rpoB, recA, sodA, rrn16 and hsp65. Bootstrap values conveying significance of the internal branch topology are clearly marked near each branch. Values above 50 were deemed to be significant to convey correct topology of the internal branches.
