The most common organism in the oceans, and possibly on the entire planet, is a family of single-celled marine bacteria called SAR11. These drifting organisms look like tiny jelly beans and have evolv...
Life’s genetic code has only ever contained four natural bases. These bases pair up to form two “base pairs”—the rungs of the DNA ladder—and they have simply been rearranged to create bacteria and but...
The toxic dinoflagellate, Alexandrium fundyense, is a photosynthetic plankton — a microscopic organism floating in the ocean, unable to swim against a current.  New research by sci...
Improperly designed road-stream crossings can fragment stream networks by restricting or preventing aquatic organism passage. These crossings may also be more vulnerable to high flow events, putting c...
RIVERSIDE, Calif. — Scientists at the University of California, Riverside have discovered a fossil of a newly discovered organism from the “Ediacara Biota” — a group of organisms that occurred in the ...
It’s broadly understood that the world’s oceans play a crucial role in the global-scale cycling and exchange of carbon between Earth’s ecosystems and atmosphere. Now scientists at Scripps Institution ...
The application of nitrification inhibitors is a technique to reduce the nitrate concentration on leachates that delay ammonium oxidation by reducing the activity of ammonium oxidizing bacteria in soi...
Developmental systems theory is an attempt to sum up the ideas of a research tradition in developmental psychobiology that goes back at least to Daniel Lehrman�s work in the 1950s. It yields a ...
The Asian type “Candidatus Liberibacter asiaticus” (Las, citrus greening organism) is severely damaging citrus production in Asia including Japan. Our previous study suggested that the bacteriophagety...
A study was carried out on the fruit rot of watermelon (Citrullus lanatus (Thunb.) Matsum. Nakai) in Ilorin, Nigeria between February and May, 2008. A large area planted to watermelon in Obbo-ille, a ...
A polymerase chain reaction (PCR)method with high sensitivity and specificity has been developed with a pair of oligonucleotide primers designed and synthesized according to the DNA sequence specific...
In this paper, I address the question of what the Developmental Systems Theory (DST) aims at explaining. I distinguish two lines of thought in DST, one which deals specifically with development, and t...
56 field hockey players from Poznan field hockey clubs were investigated. Sportsmen, running on motorised treadmill performed a maximal incremental exercise test. Physiological parameters were exami...
Mesocosm CO2 perturbation studies:from organism to community level。
Developmental systems theory is an attempt to sum up the ideas of a research tradition in developmental psychobiology that goes back at least to Daniel Lehrman’s work in the 1950s. It yields a represe...
