notes that, "As you move further north or move higher in altitude, coral snakes become increasingly rare--and attacks on the ringed snakes gradually increase.
tigrinum salamander larvae are more likely to transform into cannibals than when reared with siblings only (Pfennig
and Collins 1993), suggesting that an animal's kinship environment influences production of cannibals.
Spadefoot tadpoles often occur in nature as either an omnivore morph or as a larger, physically distinctive carnivore morph that has specialized oral structures to facilitate the ingestion of large prey (including conspecifics; Bragg 1965; for illustrations of both morphs see Pfennig
and his colleagues, University of Arizona biologist Jim Collins and Cornell University ecologist Paul Sherman, discovered in laboratory research that the predatory tadpoles had predictable eating preferences.
During this period, some of the first KM banknotes, denomination of 50 pfennig
, 1 KM and 5 KM were removed from circulation and replaced by coins.
Another reason not to eat closely related species is that they may carry pathogens that can invade more easily when consumed by a conspecific or phylogenetically close host (Pfennig
, et al.
of the University of North Carolina at Chapel Hill says the study's implication "is a very general one" Researchers studying many kinds of animal behavior, such as reactions to predators, need to consider whether animals perceive distinctions even if they don't act on them.
For solar electricity from photovoltaics, the new feed-in price is 99 Pfennig
