Threatened arthropods are defined here as any of a number of species within the phylum Arthropoda, whose extinction is likely in the foreseeable future. (wikipedia.org)
Estimating the number of threatened arthropod species is extremely difficult, primarily because a vast number of the species themselves are not yet named or described. (wikipedia.org)
Furthermore, according to Deyrup and Eisner, "The rate of destruction and degradation of natural habitats is currently so great that there are not nearly enough biologists to even catalog the arthropod species that are suddenly on the edge of extinction. (wikipedia.org)
However the expansion of human activities has led to demise of many arthropod species through the mechanisms of deforestation, conventional farming, slash-and-burn methods in the tropics, habitat fragmentation via urban development, excessive use of pesticides and even the success of forest fire suppression. (wikipedia.org)
Only a tiny fraction of the planet's endangered arthropods are formally recognized as such, as no one has ever evaluated the conservation status of the vast majority of arthropod species. (wikipedia.org)
It is difficult to estimate the total number of endangered arthropod species, since many of the taxa themselves have not been recorded. (wikipedia.org)
The total number of living arthropod species is probably in the tens of millions. (wikipedia.org)
One conservative estimate puts the number of arthropod species in tropical forests alone at six to nine million species. (wikipedia.org)
Conservatively at least eighty percent of all living animal species are arthropods. (wikipedia.org)
in addition, arthropods constitute the bulk of faunal pollinators, so that the survival of crops as well as millions of natural flora species depend on robust and biologically diverse arthropod populations. (wikipedia.org)
The survival of diverse arthropods is essential to propagation of higher animals on the food chain, e.g. those species who prey upon the insectivores and other taxa that consume arthropods. (wikipedia.org)
Even if constant arthropod total biomass results after certain arthropod extinctions, the ecosystem stability is compromised by reduction in species numbers. (wikipedia.org)
Thus extinction of arthropods species threaten to make extinct hundreds of thousands, if not millions, of higher order birds, amphibians, reptiles and mammals. (wikipedia.org)

We will study the phylogeny, anatomy, physiology, and ecology of the major extinct and extant taxa of vertebrates and discuss how each group solves the problems of finding food, finding mates, and avoiding predators. (middlebury.edu)
Insects1
The faunal composition was represented by 103 taxa distributed across five phyla, of which the highest occurrence was of arthropods, especially insects. (scielo.br)
Faunal1
Since arthropods constitute the majority of the faunal biomass on Earth, their role is vital to the survival of large numbers of insectivores and other animals that prey upon arthropods. (wikipedia.org)
Reptiles1
The term received currency during the debates of the 1960s and 1970s accompanying the rise of cladistics , having been coined by zoologist Willi Hennig to apply to well-known taxa like Reptilia ( reptiles ), which is paraphyletic with respect to birds . (wikipedia.org)
Diversity1
Functional diversity ( FD ) of pollinators can increase plant reproductive output and the stability of plant‐pollinator communities. (researchgate.net)
The long-term survival and stability of spatially structured populations in fragmented landscapes largely depends on the colonisation of habitat patches and the exchange of individuals and genes between patches. (uni-wuerzburg.de)
Habitat1
citation needed] Most endangerment of arthropod populations is from habitat destruction by growing human populations and related human activities such as agriculture, construction and transportation. (wikipedia.org)
Phylogenetic2
Comparative genomic analysis of T . equi revealed the phylogenetic positioning relative to seven apicomplexan parasites using deduced amino acid sequences from 150 genes placed it as a sister taxon to Theileria spp . (biomedcentral.com)

Major1
Transmission of arthropod-borne apicomplexan parasites that cause disease and result in death or persistent infection represents a major challenge to global human and animal health. (biomedcentral.com)
Increase1
This change in richness coincides with compositional changes, a decrease in connectedness among taxa, an increase in fragmentation of taxon co-occurrence networks, and a shift in indicator taxa. (nature.com)
Target2
Micro CT scanning was found to be a useful imaging method, particularly when the target structure is flat such as arthropod wing venation, and I recommend it to be applied when dealing with rare specimens. (helsinki.fi)
In the presence of a complex pest community, however, use of an insecticide with a high degree of specificity can require additional applications of products that target other taxa. (ucanr.edu)
