nesting locations. During the winter time birds will migrate south to not only escape the cold, but find a sustainable food source. Plants will bloom and attempt to reproduce when they sense days getting shorter. If they can't fertilize before the seasons change and they die then they wouldn't pass on their genes. So their ability to recognize a change in abiotic factors allow them to ensure reproduction. Trans-organismic communication Trans-organismic communication is when organisms of different species interact. In biology the relationships formed between different species is known as symbiosis. These relationships come in two main forms mutualistic and parasitic. Mutualistic Relationships are when both species benefit from their interactions. Take Pilot fish for example, they gather around sharks, rays, and sea turtles to eat various parasites off of the larger organism. The fish get food from following the sharks around, and the sharks receive a cleaning for not eating the pilot fish. Parasitic relationships are where one organism benefits off of the other organism at a cost. For example take mistletoe, it may be the focus of an intimate holiday tradition but it is a parasite. In order for mistletoe to grow it must leach water and nutrients from a tree or shrub. Communication between species is not limited to securing sustenance, it can come in many forms. Many flowers rely on bees to spread their pollen and facilitate floral reproduction. So they evolved bright attractive petals and sweet nectar in order to attract the bees. In a recent study done at the university of Buenos Aires, they examined a possible relationship between fluorescence and attraction. However it was concluded that reflected light was much more important in pollinator attraction than fluorescence. Communicating with other species allows organisms to form relationships that are advantageous in survival, and they are all based on some form of trans organismic communication. Inter organismic communication Inter organismic communication in communication between organisms of the same species (conspecifics), this includes human speech. Especially in humans, communication is key to upholding social structure. Dolphins likewise communicate with one another in a number of different ways by creating sounds, making physical contact with one another and through the use of body language. Dolphins vocally communicate through clicking sounds and pitches of whistling specific to only one individual. The whistling helps communicate to other dolphins the location of that individual. For example, if a mother loses
