Scales of this type, usually identified as 'Acanthodes
' sp., are not uncommon in the Devonian and Carboniferous assemblages of fish microremains.
Por esto, A[G.sup.3] incremento los porcentajes de germinacion y disminuyo el tiempo para su inicio en semillas de diferentes especies, como Ferocactus acanthodes
Cover, density and yield of Scariola orientalis , Launaea acanthodes
and Noaea mucronata were greater in grazed area, but only the yield of first species, density of second species and cover and density of third species were significantly high (p<0.05).
Fossilized rod and cone cells the kinds that help people see in color and detail have been discovered for the first time in a 300millionyearold fossil specimen of a fish called Acanthodes
bridgei, according to a scientific study recently published in Nature Communications journal.
The presence of the species, including Peganum harmala, Lounaea acanthodes
and Gundelia tornefortii in a rangeland grazed continuously with heavy grazing intensity represents non-normative utilization of these rangelands which coincided with results of the study performed by Hossienzadeh et al.
New research on Acanthodes
bronni, a fish from the Paleozoic era, sheds light on the evolution of the earliest jawed vertebrates and offers a new glimpse of the last common ancestor before the split between the earliest sharks and the first bony fishes - the lineage that would eventually include human beings.

Some seem relatively rare, such as Ephemeroporus acanthodes
and Oxyurella longicaudis, which occur in North and Central America, or the true Neotropical Chydorus dentifer.

Extrafloral nectar of Ferocactus acanthodes
(Cactaceae): composition and its importance to ants.
This has been suggested for the columnar cacti Carnegiea gigantea and Stenocereus thurberi (Parker, 1993; Pierson & Turner, 1998), the barrel cacti Echinocactus polycephalus, Ferocactus acanthodes
, and F.
