Herbivory is when the prey species is a plant. Here it is. PPT PowerPoint Presentation lessons in math, English, science, history, and more. Some defensive strategies are pretty obvious, and top among the list of obvious strategies is running away. Both predators and prey can use a variety of strategies in order to survive, including speed, flight, physical protection, camouflage, chemical compounds, mimicry and countless other strategies that we don't have time to talk about here. Let's say the number of wolves is represented by w, the number of rabbits is represented by r.The reproductive rate of rabbits is k 1 and the reproductive rate of wolves is k 2.The mortality rate for wolves is k 3.Download the excel spreadsheet to play around with different numbers for each of these parameters and watch what happens to the graphs. It uses real data to show how to model algal, water hyacinth, and fish growth; predator-prey interactions among fish, insects, and plants; lead in the bloodstream and the chelation process; and how diseases like HIV/AIDS spread through a region. 36 0 obj Predator-Prey Interactions Publisher: American Fisheries. I like this service www.HelpWriting.net from Academic Writers. . Example-Wasps To avoid being eaten or harmed by predators, many prey species have evolved defenses. Since most predators are extremely selective in their prey, prey must adapt to overcome the predation taking place against them. Oxford: Oxford Univ. For a more detailed approach, Lima and Dill 1990 provides a readable synthesis of behavioral trade-offs involved in predator-prey interactions, one that is broadened in ecological scope in Lima 1998 and, written later, Chase, et al. << /S /GoTo /D (section*.10) >> 81 slides Identification of predators ppt Nisha Nepoleon 9.5k views 42 slides Predator/Prey Interactions coebridges 3.6k views 10 slides More Related Content Slideshows for you (20) Animal Behavior: Food selection sudeshrathod sudesh rathod 8.7k views 02 classifying species mrtangextrahelp 1k views Chapter 4 interaction between organism Camouflage is a great defensive strategy, as evidenced by its widespread use in nature, but there is no rule that says it can only be used to hide from predators. Coevolution occurs when the fitness of two different species is tightly linked, and these two species evolve in response to evolutionary changes in each other.

Prey species do not perform the same antipredator behaviors during every encounter; it is likely that certain reactions are more apt for evading specific types of predators. PPT - Predators, Predation, & Predator Control PowerPoint presentation When an unsuspecting fish goes after the tongue, the turtle snaps its mouth shut and eats the fish instead. Canadian Journal of Zoology 68:619640. See especially p. 394. The very distinctive-smelling spray of the skunk comes to mind, and the bombardier beetle sprays would-be predators with a toxic chemical in a similar fashion. 65 0 obj << Disease would cause a decrease in the wolf population, so fewer moose would be eaten and the population. Predator-prey interactions are built around the concept of coevolution. 2002. The alligator snapping turtle uses its pink worm-like tongue as a lure to draw fish right into its mouth. << /S /GoTo /D (section*.14) >> G. P. Samanta's Lab - ResearchGate However, it is unclear if increased mortality results from changes in the dynamics of predator-prey interactions or due to prey increasing activity levels. In predator-prey relationships, prey develop adaptations to avoid predators and predators acquire additional adaptations in turn. She is a Certified Google Level 1 Educator and is part of the Edulastic Innovator Team and her campus Leadership Team. 16 0 obj 9 0 obj endobj Smaller predators typically kill smaller prey due to body size constraints on their physical ability to capture and subdue prey, and the risks that larger prey may impose (Clements et al. Interdependence of Living Things Unit - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. Short-term behavioral changes are rarely investigated, and little information is available on the factors that select for short- over long-term avoidance nor the time-scale (i.e., hours, days, weeks) of these responses. Honeybees use vibrations rather than auditory signals to warn others in the hive of predators. Venomous snakes, spiders and wasps use poisons to either kill or immobilize their prey.

One example is camouflage, which is the process of using specialized colors to blend in with the environment. 1 - catch rate.

Conversely, prey is a term used to describe animals that are hunted and killed by predators. endobj Many types of butterflies also practice Batesian mimicry. Can you find the camouflaged animal in this picture? PPT PowerPoint Presentation ! " A very common and universally known warning coloration is the black and yellow stripes of many species of wasps, hornets and bees. 1475 Gortner Ave The following section outlines predator and prey examples. An extension of the logic of Lima and Dill 1990 applied to larger-scale phenomena, this review examines the influence of predator-prey behavior on population processes.
