Predator–prey Reversal
Predator–prey reversal is a biological interaction where an organism that is typically prey in the predation interaction instead acts as the predator. A variety of interactions are considered a role reversal. One type is where the prey confronts its predator and the interaction ends with no feeding. Two competing predators may interact and the larger predator will prey on the smaller. Smaller organisms may prey on larger organisms. Changing population densities may trigger a role reversal. In addition, adult prey may attack juvenile predators. Evolution theories According to Georgia Institute of Technology research, prey and predator roles have cycles where the prey population may increase, thereby causing the predator population to increase as well. But sometimes the predator population overwhelms the prey to the point of devastating the prey population, subsequently resulting in a devastation of the predator population. Some studies indicate that the roles of each may become r ...

Predator–prey
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and ...

Natural Resource
Natural resources are resources that are drawn from nature and used with few modifications. This includes the sources of valued characteristics such as commercial and industrial use, aesthetic value, scientific interest and cultural value. On Earth, it includes sunlight, atmosphere, water, land, all minerals along with all vegetation, and wildlife. Natural resources is a part of humanity's natural heritage or protected in nature reserves. Particular areas (such as the rainforest in Fatu-Hiva) often feature biodiversity and geodiversity in their ecosystems. Natural resources may be classified in different ways. Natural resources are materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such as fresh water, air, as well as any living organism such as a fish, or it may be transformed by extractivist in ...

Kirkaldyia Deyrolli
''Lethocerus deyrollei'' is a species of giant water bug (family Belostomatidae) that traditionally is included in the genus '' Lethocerus'', although recent authorities place it in the ''Kirkaldyia''.P. J. Perez-Goodwyn (2006). ''Taxonomic revision of the subfamily Lethocerinae Lauck & Menke (Heteroptera: Belostomatidae)". Stuttgarter Beiträge zur Naturkunde.'' A (Biologie) 695: 1–71. They are large ( long), predatory and nocturnal insects. They are one of the best known giant water bugs and are found in Japan, Korea, east China, east Indochina and the Amur region of Russia. They are very common in much of their range, but have declined drastically in some regions and are considered threatened in JapanHirai, T.; and Hidaka, K. (2002).

Cecropia Obtusa
''Cecropia'' is a Neotropical genus consisting of 61 recognized species with a highly distinctive lineage of dioecious trees. The genus consists of pioneer trees in the more or less humid parts of the Neotropics, with the majority of the species being myrmecophytic.Berg, Rosselli & Davidson (2005) Berg and Rosselli state that the genus is characterized by some unusual traits: spathes fully enclosing the flower-bearing parts of the inflorescences until anthesis, patches of dense indumentums (trichilia) producing Mullerian (food) at the base of the petiole, and anthers becoming detached at anthesis. ''Cecropia'' is most studied for its ecological role and association with ants. Its classification is controversial; in the past, it has been placed in the Cecropiaceae, Moraceae (the mulberry family), or Urticaceae (the nettle family).Burger (1977) The modern Angiosperm Phylogeny Group system places the "cecropiacean" group in the Urticaceae. The genus is native to the Ameri ...

Arboreal
Arboreal locomotion is the Animal locomotion, locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally, but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species.Cartmill, M. (1985). Climbing. In ''Functional Vertebrate Morphology'', eds. M. Hildebrand D. M. Bramble K. F. Liem and D. B. Wake, pp. 73–88. Cambridge: Belknap Press. Furthermore, many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. Some animals are exclusively arboreal in habitat, such as the tree snail. Biomechanics Arboreal habitats pose numerous mechanical challenges to animals moving in them, which have been solved in diverse ways. These challenges include moving on n ...

Azteca Andreae
''Azteca andreae'' is an arboreal ant species found in the tropics of South America, most notably in French Guiana. They are most notable for their predatory skills and strength. They are ambush predators that are able to capture and eat other insects much greater than their own size. Physical characteristics ''A. andreae'' have dark brown, shiny bodies covered in white hair. The workers are a little less than 3mm in length, and the queen is slightly more than 5mm in length.Guerrero R., Delabie J., Dejean A. (2010) "Taconomic contribution to the aurita group of the ant genus Azteca (Formicidae: Dolichoderinae)." J. Hym. Res. 19 (1):51-65 Habitat The ants live in the hollow internodes, or the spaces in between nodes on the plant stem, of select plant species. When the queens start a new colony, they apparently limit their colonies to ''Cecropia'' trees. They will inhabit multiple different species of tree, but they have a preference for ''Cecropia obtusa''. Up to 8350 workers ...

Epomis Larvae Preying On Amphibian
''Epomis'' is a genus of ground beetles (Carabidae). The larvae of this genus are notable for being obligate role-reversal predators. Amphibians such as frogs are normally predators of beetles; however, ''Epomis'' larvae feed exclusively on amphibians. Description ''Epomis'' beetles are often metallic blue- or green-colored, with a striking yellow-orange rim on the elytra and mostly yellow-colored legs and antennae. They are in length.Basilewsky, P. (1955). Révision des epèces africaines du genre Epomis (Carabidae). Transactions of the Royal Entomological Society of London 107: 95-116. They can be distinguished from the closely related genus '' Chlaenius'' by the short (less than three times as long as wide) and triangular labial palps.Trautner Jürgen, & Geigenmüller Katrin (1987). ''Tiger beetles, ground beetles. Illustrated key to the Cicindelidae and Carabidae of Europe.'' TRIOPS Verlag. The larvae reach a body length up to , they are white or yellow colored, with bla ...

Larvae
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...
