The stink bug, derives its name from its tendency to eject a foul smelling glandular substance secreted from pores in the thorax when disturbed. The chemicals involved include aldehydes, making the smell similar to that of coriander; whether or not a human finds the smell unpleasant or pleasant may be genetic. In some species the liquid contains cyanide compounds with a rancid almond scent. This is a form of antipredator adaptation.
The yellow longnose butterflyfish or forceps butterflyfish, Forcipiger flavissimus, is a species of marine fish in the family Chaetodontidae. It is a small fish which grows up to 22 cm in length. Their longnose gives them the other name, Forcep Fish. The extended mouth gives them the opportunity to hunt among crevices of hard corals for shrimps and crabs as shown in the picture. Being territorial, yellow longnose butterflyfish patrol their patches of coral with a monogamous partner. However, instances of overt aggression among F. flavissimus have been observed between territory holders and individuals of the same sex. Chasing is rare, but when it does occur, males chase males and females chase females. Females defend food resources from other females, while males defend territories containing a female from other males. Territoriality is a favorable strategy for a species to adopt primarily when resources are temporally stable, predictable, and evenly distributed throughout a territory. Territoriality is commonly displayed by benthic-feeding longnose butterflyfish, therefore, because their main dietary resources fulfill these characteristics. Their monogamous pairing appears to be closely linked to their territorial behavior. Although several could cause a species to evolve monogamous behavior, the necessity for biparental care does not applies to longnose butterflyfish because they lay pelagic, or freely floating, eggs. One source of selective pressure responsible for the monogamous pairs observed could be the advantage of territorial defense it provides. Monogamy is favored when a pair makes the defense of one or more resources more efficient than defense by a solitary individual. Longnose Butterflyfish pairs have been confirmed by studies to be heterosexual and pair fidelity has been observed for periods of up to seven or more years.
For the developers at New York start-up Networked Organisms, smartphones are the butterfly nets of the 21st Century. Their tool, Project Noah, lets people upload photos of plants and wildlife around them, creating a map of the natural world and contributing to scientific research in the process.
Bespectacled scientists of yore would carry around hefty field guides, made up of hundreds of pages of text and photos. But these days, smartphone owners have a lighter option: an app called Project Noah, which aims to help people identify plants and animals as well as collect data from "citizen scientists" about where certain species are located.
Project Noah enables us to be part of a more focused online community where we can learn more about wildlife around us and contribute to scientific research. It pulls participants into deeper, more meaningful engagement by enabling people to go on “missions” to collectively map changes based on sightings.
A modern invention that may also hold the key to saving species in the future. Project Noah is a global study that encourages nature lovers to document the wildlife they encounter, using a purpose built phone app and web community. In addition to the virtual "collection" of species, Project Noah encourages citizen science by linking up with existing surveys including the International Spider Survey and the Global Coral Reef Monitoring Network.
