** Eunectes murinus, the green anaconda, the largest species, is found east of the Andes in Colombia, Venezuela, the Guianas, Ecuador, Peru, Bolivia, Brazil and on the island of Trinidad.

** Eunectes notaeus, the yellow anaconda, a smaller species, is found in eastern Bolivia, southern Brazil, Paraguay and northeastern Argentina.

** Eunectes deschauenseei, the dark-spotted anaconda, is a rare species found in northeastern Brazil and coastal French Guiana.

** Eunectes beniensis, the Bolivian anaconda, the most recently defined species, is found in the Departments of Beni and Pando in Bolivia.

** P. polyanthus ( aka P. Dumosus, recognized as a separate species in 1995 )

** Community ecology: community — keystone species — mimicry — symbiosis — pollination — mutualism — commensalism — parasitism — predation — invasive species — environmental heterogeneity — edge effect

** Leycesteria: 6 species

** Lonicera ( Honeysuckle ): 180 species

** Symphoricarpos ( Snowberry ): 17 species

** Triosteum ( Horsegentian ): 6 species

** Frog Xenopus ( includes two species: Xenopus laevis and Xenopus tropicalis )

** Pocket gophers ( family Geomyidae ), about 40 species distributed from North America to Colombia

** Hemlock ( Conium ), two species, one formerly used as a method of execution

** Larentia clavaria – mallow, species of moth

** Order Didelphimorphia ( 93 species )

** Order Paucituberculata ( 6 species )

** Order Microbiotheria ( 1 species )

** Order Dasyuromorphia ( 71 species )

** Order Peramelemorphia ( 24 species )

** Order Notoryctemorphia ( 2 species )

** Order Diprotodontia ( 137 species )

** Ailuropoda microta, extinct species sometimes called Dwarf or Pygmy giant panda

** Reducing agent, element or compound in a redox reaction that donates an electron to another species

** Battle of Placentia — Emperor Aurelian is defeated by the Alemanni forces invading Italy

** Battle of Fano — Aurelian defeats the Alemanni, who begin to retreat from Italy

** Battle of Pavia — Aurelian destroys the retreating Alemanni army.

** Battle of Lingones — Caesar Constantius Chlorus defeats the Alemanni

** Battle of Vindonissa — Constantius again defeats the Alemanni

** Thoracic aorta — the half of the descending aorta above the diaphragm

** Abdominal aorta — the half of the descending aorta below the diaphragm

** France — voltage change 3 kV DC – 25 kV AC

** Germany — voltage change 3 kV DC – 15 kV AC

** Netherlands — voltage change 3 kV DC – 1500 V DC

** Luxembourg — no voltage change at the border ( the line Arlon-Luxembourg is at 3 kV DC and the line Gouvy-Luxembourg is at 25 kV AC )

** Channel Tunnel — voltage remains at 25 kV AC.

** UK — voltage remains at 25 kV AC — voltage change 750 V DC third rail ( The Southern Region ).

** CS — Caught stealing: times tagged out while attempting to steal a base

** SBA / ATT — Stolen base attempts: total number of times the player has attempted to steal a base ( SB + CS )

** DI — Defensive Indifference: if the catcher does not attempt to throw out a runner ( usually because the base would be insignificant ), the runner is not awarded a steal.

** Autecology: autotroph — heterotroph — acclimatization — endotherm — ectotherm — hibernation — homeostasis — behavior — circadian rhythm

** The fact that this pattern of speciation occurred the same way on three separate occasions suggests strongly that ecological factors in a sympatric population can cause speciation.

In Devonian | Late Devonian vertebrate speciation, descendants of Pelagic zone | pelagic Sarcopterygii | lobe-finned fish – like Eusthenopteron – exhibited a sequence of adaptations: * Panderichthys, suited to muddy shallows ; * Tiktaalik with limb-like fins that could take it up onto land ; * Tetrapod | Early tetrapods in weed-filled swamps, such as: ** Acanthostega which had feet with eight digits, ** Ichthyostega with limbs.
