A species complex is a group of closely related species, where the exact demarcation between species is often unclear or cryptic owing to their recent and usually still incomplete reproductive isolation . Ringspecies , superspecies and cryptic species complex are example of species complex. Such groups of species with complex relationship between species may occur in a line undergoing rapid speciation or where such speciaton recently have occurred, so that species separation mechanisms has yet to be fully developed. Such cases may leave some species paraphyletic at the species level and to hybrid speciation hybrid species , making phylogeny phylogenetic analysis difficult. Species complexes are more common among plants , but animal examples exist, such as the dog wolf coyote complex the genus Canis and the cobras genus Naja . Often such complexes only become evident when a new species is introduced into the system, breaking down existing species barriers. An example is the introduction of Spanish slug in Northern Europe , where interbreeding with the local black slug and red slug , traditionally considered clearly separate species that did not interbreed, shows these may actually be subspecies of the same species. ref da icon Engelke, S. 2006?

About an ecological term Common disambiguation Definitions Common species and uncommon species are designations used in ecology to describe the population status of a species. Commonness is closely related to abundance ecology abundance . Abundance refers to the frequency with which a species is found in controlled samples in contrast, species are defined as common or uncommon based on their overall presence in the environment. A species may be locally abundant without being common. However, common and uncommon are also sometimes used to describe levels of abundance, with a common species being less abundant than an abundant species, while an uncommon species is more abundant than a rare species. ref cite web url http www.npwrc.usgs.gov resource birds stcroix methods.htm work Birds of the St. Croix River Valley Minnesota and Wisconsin title Methods, Terminology, and Nomenclature author Northern Prairie Wildlife Research Center accessdate 2006 12 31 year 2006 ref Common species and conservation Common species are frequently regarded as being at low risk of extinction simply because they exist in large numbers, and hence their conservation status is often overlooked. While this is broadly logical, there are several cases of once common species being driven to extinction such as the Passenger Pigeon and the Rocky Mountain locust , which numbered in the billions and trillions respectively before their demise. Moreover, a small proportional decline in a common species results in the loss of a large number of individuals, and the contribution to ecosystem function that those individuals represented. A recent paper argued that because common species shape ecosystems, contribute disproportionately to ecosystem functioning, and can show rapid population declines, conservation should look more closely at how the trade off between species extinctions and the depletion of populations ...
