The effects of ranges of values and of anomalous values of the growth rates and interaction constants that characterise species could be studied much more rapidly than by experiment.
The WorldClim parameters express spatial variation in annual means, seasonality and extreme or limiting climatic factors and represent biologically meaningful variables for characterising species distributions [29].
While short separation times may characterise species pairs that are perfectly distinct by criteria of diagnosability and even reproductive isolation, a long time since separation does considerably strengthen other evidence for species status.
For tall fescue, which remains a poorly characterised species with respect to available genomic resources, the targeting of genome-wide distributed regions for resequencing is best achieved using a comparative genomics approach.
He spells it out: all the drive, wit, love, pride, anger, hope and anxiety that characterise the species Homo sapiens are simply there to perpetuate the biological cycle.
At least 79 carry more than one such pathogen.The team used 86 criteria to characterise rodent species, including how fast they breed, the types of habitat they live in and the specifics of their physiology.
However, scientists have discovered that throughout Europe, vole populations are no longer showing the dramatic boom-and-bust cycles that have characterised the species on which many other animals depend for survival.
X-ray and infrared spectroscopy were used to characterise the species formed at the surface.
The results can help characterise the species investigated, indicate the presence of some biologically active compounds and shed light upon their reported mild toxicity.
Winter seed banks and summer deep seed bank did not contribute much to either effect and were characterised by species dating back from past cultivation.
