Only nine of 58 extinct and extant animal phyla have terrestrial representatives (Labandeira and Beall 1990), largely because land presents a new and hostile environment for a marine organism (Selden and Jeram 1989; Selden and Edwards 1990).
One possible difference between the datasets is that most of the phylogenies analysed by Thomas et al. contained exclusively terrestrial invertebrates while most of the substitutions measured in the current study will have taken place in a marine environment (even for phyla with many living terrestrial representatives).
The study provides a simple and straightforward method for detecting freshwater priority areas based on endemism and threat, and represents a starting point for integrating freshwater and terrestrial conservation in representative and biogeographically consistent site-scale conservation strategies, that may be scaled-up following naturally linked drainage systems.
Since the aim of this study was to unveil the characteristic amino acid metabolism observed in cetaceans, compared with representative terrestrial animals, we chose mice as one of the most intensively investigated terrestrial model animals.
The extent to which extraterrestrial life questions can be confidently addressed rests in large measure on the extent to which terrestrial life is representative of life in general since we will have to draw from terrestrial life knowledge.
In this work, we provide a review of representative terrestrial, aerial and aquatic keratinous materials, pangolin scales, feather shafts and baleen plates, and correlate their hierarchical structures to the respective functions of dermal armor, flight material and undersea filter.
This paper outlines a long-term research program that could inform the extent to which terrestrial life is representative of life more generally, which might then help inform our level of confidence in applying terrestrial life knowledge to extraterrestrial life issues.
We present an adjusted multidimensional spatial human footprint index (SHFI) to analyze the effects of landscape transformation on the remnant habitat connectivity for 40 terrestrial mammal species representative of the Trans-Mexican Volcanic System in Michoacán (TMVSMich), in western central Mexico.
Klein et al. integrate land-sea planning by optimising the design of Fiji׳s expanded protected area network to benefit coral reefs, while maintaining a terrestrial network that is representative of Fiji׳s various terrestrial ecosystems.
