The study of living organisms in their natural surroundings or environment is called natural history. An important aspect of this study is external morphology or the science of external form of organisms. A naturalist will observe and record the external appearance and relative positions of body ...

and an explanation of how to best use this coloring book. The next section is organized by communities in which the organisms live. The final section details the variety of major groupings - phyla - within each kingdom and shows how the organisms in each are distinguished from one other. ...
This is because rep-PCR uses oligonucleotide primers complementary to repetitive sequences spread throughout the genome of living organisms. The result of amplicon differences was found in specialized locations around genes (Mohapatra et al. 2007). The use of such techniques has also helped in ...
Climatic changes that greatly affected living organisms accompanied these plate movements; the period was marked by occasional waves of mass extinctions灭绝of living creatures. Organisms were also affected by periods of glaciation冰川作用that followed variations in the earths orbit 地球轨道and in the ...
Land use change—for example, the conversion of natural habitats to agricultural or urban ecosystems—is widely recognized to influence the risk and emergence of zoonotic disease in humans1,2. However, whether such changes in risk are underpinned by predictable ecological changes remains unclear. It...
The recovery of genomes belonging to uncultured groups from the environment has resulted in the description of several new phyla, many of which are globally distributed and are among the predominant organisms on the planet. In this Review, we discuss how these genomes, together with long-term ...
was accomplished through human selection for desirable genetic mutations from natural populations. A better understanding of the genetic basis of domestication will help to improve domesticated organisms and open opportunities for new domestications. In addition, genetic evidence has revealed many details, ...
Freshwater species recorded in the Okavango Delta and Lake Ngami To establish which organisms should be included in this review, we followed the definition of freshwater species by Darwall et al. (2009): “those which depend upon freshwater habitats for any critical part of their life cycle” ...
Fungi are major ecological players in both terrestrial and aquatic environments by cycling organic matter and channelling nutrients across trophic levels. High-throughput sequencing (HTS) studies of fungal communities are redrawing the map of the fungal kingdom by hinting at its enormous — and largely...
