Unfortunately, however, relatively few fossil insects of this age are known and there is a great need for further discoveries. The oldest known fossil insect is currently Rhyniognatha hirsti from the early Devonian fossils in Scotland. However, this species, preserved in sinter (mineral sediment)...

Ad 2: Schoenemann and Clarkson2offer an alternative interpretation of the observed structures of the fossil compound eye. The general problem of fossils is that we are facing a pattern that is a mix of incomplete organismic structures and diagenetic impact. Hence, the pattern has to be interpret...
Complex ichnofossils constructed since the Mesozoic by termites (Isoptera), bees (Hymenoptera: Apoidea), wasps (Hymenoptera: Apoidea and Vespoidea), and ants (Hymenoptera: Formicidae) represent unique solutions through degrees of social cooperation to the problems of fossorial life in terrestrial ...
A Johns Hopkins paleontologist and her collaborative team of scientists report they have clear evidence that the arrival of humans and subsequent human activity throughout the islands of the Caribbean were likely the primary causes of the extinction of n
"In the diseased trees we studied, the protein levels of some PLCPs were increased, presumably attempting to combat the bacterial infection," Ma said. "However, the bacterium fights back, by inhibiting the enzymatic activity of PLCPs through SDE1." ...
Special nutritional and other biological traits associated with coping with infertile lands should be evident, accentuated in plants, for example, through water-foraging strategies, symbioses, carnivory, pollination and parasitism. The uniquely flat landscapes of southwestern Australia have had prolonged ...
burning of fossils fuels, military operations, metalliferous mining and anthropogenic activities, there has been an increase in the threshold level of various metals and metalloids in the past 50 years. As a result, the long-term effects of various metalloids have been assessed on the environment,...
