Human behavioral ecology

invasives are overtaking the native species. This helps prove my point that non-native invasive plant species are taking over locations that are home to many native plant species. Both authors of this article have an extensive background in ecology focusing on the ecology of biological invasion and are published in a well-known journal. The results of this article are concurrent to the rest of my previous…

Explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills. Biogeochemical cycling is defined as the chemical element flow between the living and nonliving components of the ecosystem. This is the cycle of nitrogen, phosphorus and carbon being converted into organic substances of plants and animals that are released back into the environment. There are three ways that human activities cause an imbalance of…

The consumption of human beings has been tripling yearly due to increasing population. Lifestyle habits that are degrading to the environment are piling up in numbers, the concern for the environment has been a very global and societal issue of quite a long time but until…

A refugee is an individual who leaves their home country owing to insecurity while seeking asylum in a foreign country that hosts them. According to Collier (2013), refugees are only beneficial to their host country to a given extent beyond which they become a burden. Hence, refugee numbers must be regulated to maximize the benefits of refugees while minimizing the demerits of refugees to the host country (Farazmand, 2014). This essay will discuss that the beneficial or disadvantageous…

Several environmental risks has been discovered (aside from the coal industry) that has put our environment in a great amount of danger. These specific concerns faced by our environment include dams, natural disasters, and endangered species. Dams were found to have a major influence on our water impact, leading to major issues in our economy. In contrast to dams natural disasters are more of a natural process that bring on different types of environmental risks. While dams mainly effect our…

Ecotourism can be described as responsible travel to natural areas which not affect the natural resources and preserve the benefit of local populations (TIES, 2015).Ecotourism no only protect the environment, it also admire the natural environment characteristics and respect the local culture. Ecotourism encourage visitorsto enjoythe natural environments with minimum impact and includes education to environmental conservation (Bob et al., 2008). Ecotourism means people travel to destinations…

Even from that limited perspective like a company…

I believe everyone has an ability to create a positive change in community. As Kofi Annan, the former secretary general of United Nations said, “Young people should be at the forefront of global change and innovation”, strengthen my desire that I am an agent of change to make this world a better place. The little change I always want to install is creating sustainability and better livelihood as a solution because humanity is placing inordinate demands on nature and our environment condition is…

Presence of carnivores helps to maintain the integrity of ecosystems throughout the world (Soulè and Terborgh, 1999). Many carnivores are capable of altering trophic structure and biodiversity through a process known as top-down control (Elmhagen and Rushton, 2007). Through this, carnivores are able to prevent the overabundance of herbivores. If uncontrolled, an explosion in herbivore population density would increase the grazing pressure that would ultimately threat the survival of the…

Niche that the organism fills The ecological niche or niche of an organism is the place and role in nature. This encompasses what it does, who it feeds, what it feed on as well as what it pollinates. Considering the role that the Brenton Blue butterfly fills, we find that like other butterflies, it serves as a pollinator. In this case, the Brenton Blue is a pollinator for its food plant, Indigo (scientific name Indigofera erecta). When the butterfly lands on the plant to feast on the nectar…
