Thus they warrant conservation consideration, says Mark Huxham, an ecologist at Napier University in Edinburgh, U.K.
In 1997, the dusky shark was identified as a "Species of Concern" by the NMFS, meaning that it warranted conservation concern but there was insufficient information for listing on the U.S. Endangered Species Act (ESA).
Unlimited harvest and sparse information warrant conservation concern for mountain lions in Texas.
Additionally, a number of recognized taxa are taxonomically challenging to delineate in the field, making it unclear which populations warrant conservation attention and protection (e.g., A. skinneriana and A. fasciculata).
Many salmon populations in the Pacific Northwest are already threatened with extinction, so the effects of climate on absolute fitness (i.e. a population's capacity for replacing itself) warrant conservation concern, and must be considered in the context of a web of natural and anthropogenic agents of selection (Waples et al. 2008).
Should tropical climates harbor ancient clades, the additional evolutionary history within these areas warrants additional conservation concern [30] and human-induced extinction in these areas will be even more grave than previously thought.
As the only Caribbean coral that forms tall vertical pillars, and as the only species in its genus, D. cylindrus warrants enhanced conservation concern because it is morphologically and evolutionarily unique (e.g., [ 4- 6]).
Proponents of this view feel that a species should not have to benefit humanity in some to warrant its conservation or survival.
Although at first sight it may seem like a juxtaposition, the health benefits of parasites may be a great reason to warrant their conservation.
The residuals of the large-scale algebraic equation system are guaranteed to be continuously driven down to the level of the computer machine round-off error on each time marching step, which warrants strong conservations of mass and momentum satisfied over all the control volumes.
