The frequency at which animals of different taxonomic groups
are reported to be killed on roads varies greatly.
In this study, we aimed to comprehensively review the existing literature related to forest tree species in Mexico to (1) evaluate variation in wood carbon concentration across taxonomic groups
and climatic regions in Mexico; (2) document the general scope of carbon storage of aboveground biomass for each type land use, and (3) make this comprehensive review easily available using internet technology.
On the other hand, more than half of the total individuals (52%) concentrated on only one taxonomic group
, Entomobryomorpha, on the FF average (Figure 2).
County data by taxonomic group
are available in supplementary table S3.
This is a first-class product, worth the cost, and will hopefully stimulate research on this neglected taxonomic group
Nonmetric multidimensional scaling (NMDS) ordination was used to compare arthropod taxonomic group
abundance dissimilarities and relate those to environmental factors ([R.
The rest of the zooplankton taxonomic groups
are generally little known for Mexican waters (Brinton et al, 1986).
Then a "handbook" section discusses birds by taxonomic group
and gives more detail on range, on endangerment and conservation.
I am a fan of books that cover a well defined taxonomic group
, the genus Euastacus in this case, in detail and in a popular format.
Arthropods form the taxonomic group
comprising crustaceans, arachnids and insects.
Different conclusions can be obtained when the entire community is analyzed or when only a taxonomic group
is used as bioindicator.

Concordance between the taxonomic groups
would reveal similar responses to environmental factors and it would indicate the viability of using one taxonomic group
for the detection of impacts on aquatic ecosystems.
For these groups, molecular dating may also provide additional insight into the true ages of the taxonomic group
A three-way analysis of covariance (ANCOVA) (Zar, 1984) was performed for each taxonomic group
using the number of individuals (total caught by category) as the dependent variable and year, region, hook type, and depth as independent variables and effort as the covariate.
