b) (15 points). Which of these nine boundaries have already been crossed? What are the potential impacts of crossing those boundaries? 1. Climate Change. We are putting too much greenhouse gases into the atmosphere, and on the verge of massive climate change. Some potential changes are it is three times more likely nitrogen will get into the atmosphere than the earth can sustain. Increase in the loss of major ice sheets, accelerated sea level rise and abrupt shifts in forest and agricultural…

Chapter IV Prey Sensitization, Learning and Memory in Reduviids: Implications in Biological Control 4.1. Introduction Sensitization is an increasing response to a stimulus presented repeatedly while habituation denotes a failure of response to the stimulus (Staddon, 1988). The process of sensitization has enormous adaptive value. When a prey escapes from the clutches of a predator as a result of exhibiting a response, it gets sensitized. If and when a second attempt at capture is initiated by…

The Nullarbor Plain Desert Ecosystem Lars Hunt Location: The Nullarbor Plains Desert spans Western and Southern Australia, between approximately 30°S-32°S, 121°E-134°E (figure 1) (Ref 1). The Nullarbor plain is bordered by the arid salt lakes region of Western Australia, arid plains of Southern Australia, and North by the Great Victoria Desert. It is bordered on the south by the Great Australian Bight seacoast (Ref 2). Figure 1 - Location of Nullarbor Plain Biome: The Nullarbor…

leaf litter as a food source and decompose it. The insects then feed the fish, and other wildlife in turn eat the fish. Reforestation also provides a food source and shelter for wildlife species including beavers, otters, birds, bats, reptiles, and amphibians, and vertical cover is critical for species like deer and bobcats. Thus, reforestation creates a chain effect in reestablishing microhabitats. (Kelly,…

Each rainforest differs in the animals it inhabits. Some of the animals that can be found are insects, fish, birds, reptiles, amphibians, and mammals (EL, 2014: para.4). The animals live in the four layers of the rainforest. The Emergent layer: This is for animals such as parrots, vultures and eagles, macaws. The vultures help eat the dead animals which help keep the rainforest clean, the birds from this layer also help to create new plants in this rainforest by eating seeds then dropping them…

The Atchafalaya River The Atchafalaya River is a distributary of the Red River and Mississippi River section in part of the southern portion in central Louisiana. The Atchafalaya is a one hundred and thirty seven mile long distributary of the Mississippi and Red Rivers. The name "Atchafalaya" comes from the Choctaw language and translates to long river from hachcha, “river" and falaya, "long.” During the fifteenth century the Mississippi River and the Red River were separated. These two rivers…

BioMedCentral.com, Aristotle observed a lizard regenerating its tail in 330 BC (Jessop). However, lizards are not the only animals capable of regenerating a lost or damaged appendage; Zebrafish can regrow a lost fin or even a heart, newts and other amphibians can regrow entire limbs, starfish can regrow their entire body from just a single limb, and a deer can regenerate its antlers (Vezina). How amazing would it be if humans had this ability too? By studying these animals, scientists are…

How can animals facing extinction be helped using modern science? Identification and description of the problem Extinction is referred to as the death of the last organism of a certain species; thus ending those organisms altogether. However, since most species are globally spread out this is something that takes careful consideration of every fact such as ‘is there a possibility the organism may have has a chance of survival somewhere unexpected?’(Hawking, 2012) Biologists have been trying…
