Red imported fire ants (RIFA) are invasive nuisance insects that have spread throughout the southeastern United States since their initial arrival more than sixty five years ago. Red imported fire ants, or Solenopsis invicta Buren, is native to Mato Grasso, Brazil and other areas throughout central South America and was accidentally brought to Mobile, Alabama in the early 1940s. Although the method of introduction is not clear, the USDA states that it is possible that the species may have arrived

that this poor gone species lived on because of more agriculture. These birds use to be the world’s most numerous birds, a population of 3-6 billion! The passenger pigeon niche in the ecosystem was to carry seeds when they fly and drop them so more plants can be harvested, also the passenger pigeon flies about 60-70 miles per hour(mph) as result when they fly the break the top of the forests branches and opens it up for more sunlight to get through which is better for the ecosystem especially for the

The geographical point 27°34'37.32"N 80°38'45.02"W reveals a sun-soaked orange grove owned by Peterson’s Groves & Nursery situated on the peninsula of Florida, in a town called Vero Beach. According to a representative from Peterson’s, the farm is not organic and consists of two locations- one 20-acre and one 13-acre. All oranges are harvested by hand and tractors are used for mowing. Multicropping is the method used to grow the orange trees as no fields are left fallow. Peterson’s Groves offers

Hybrid zones have drawn great interest because they provide opportunities for further studies of the processes involved in divergence and recombination of species. Hybrid zones can be classified as primary or secondary, depending on their origins. In this study, we considered the hybrid zone within the Northern Flickers, which has been stable on the United States’ Great Plains throughout time. The interaction between the Red- and Yellow-shafted subspecies of Northern Flickers provides a great opportunity

Biological processes often only occur under specific conditions, such as temperature, pH, and pressure. Likewise, the photosynthetic pathway can only occur effectively when such conditions are met. In the case of temperature, variations in thermal energy can cause alterations in chloroplast functionality. On the colder extreme, the rate of photosynthesis is hindered due to a decrease in H+ concertation due to an alteration in the movement of the thylakoid membrane (Busch et al. 2006). Alternatively

In Elizabeth Kolbert’s book, The Sixth Extinction: An Unnatural History, she details her travels around the world which she has taken to learn more about the rapidly declining populations of several species. With each chapter centered on a different species, Kolbert illustrates the picture of a sixth mass extinction, one anthropogenically caused, a feature that distinguishes this extinction from the five previous ones. Certain species all across the world witness their populations dwindling to abismal

The effect of horn on Megasoma elephas beetles Introduction: Megasoma elephas, a large and distinctive tropical beetle inhibits a variety of tropical forests, including tropical plantations and sometimes forest remnants,at elevations up to around 1000 metres.(Wildscreen, 2015). This types of species have a Long, rhinoceros-like horn on its head, its unusual structure is found only in male, which means Megasoma elephas is sexual dimorphic. In addition, male elephant beetles use their

Most people go through their lives not worrying about when humans may go extinct. In the past, there has been five other mass extinctions. About 450 years ago was the first mass extinction called the late Ordovician, followed by the Devonian, Permian, Triassic and the Cretaceous extinction. All of these extinctions were caused by similar changes. The question is: Are humans in a sixth extinction? The answer is yes, humans are in a sixth extinction because of the extinction of multiple animals, humans

Nepenthes gracilis is a carnivorous plant found mostly in humid, tropical climates, such as South-Eastern Asia, Australia, and Madagascar, however they grow in soils that lack essential nutrients (nitrogen and phosphorus) to their survival (Adlassnig 2011). In order to offset this fact, N. gracilis has adapted the ability to trap its animal prey and obtain those nutrients it lacks in its soil through its prey, consisting of arthropods (mostly ants). As ants climb onto the inner surface of N. gracilis
