• AP Biology Russia Ukraine

  My AP Biology Thoughts Unit #: 8EPISODE TITLE: Welcome to My AP Biology Thoughts podcast, our names are Ramit Dasika, Flavio D’Attilio, Samy Leroux, Landon Schafer, Colin Fahmy and we are hosting this episode called Unit 8 Ecology AND Today we will be discussing The war between Ukraine and Russia has caused mass destruction to many ecosystems through bombings and other weaponry and how it relates to the AP Biology Curriculum. Segment 1: Overview of Topic War The war between Ukraine and Russia has caused mass destruction to many ecosystems through bombings and other weaponrySegment 2: Evidence that supports It causes forest fires- SamyDuring the process of runoff, the harmful chemicals are collected in rivers nearby. This causes the water sources contaminated due to chemical leakage from destroyed industrial plants-RamitDuring the Russia-Ukrainian War, the Russian soldiers damaged and looted fire engines, computers, and radiation monitoring equipment, while leaving mines and munitions spread across the exclusion zone.-Flavio“In the Donbas region, wrecked sewage works gush their contents into rivers and damaged pipelines fill wetlands with oil.”- Landon“Most of the exclusion zone was damaged by the invasion and may be contaminated with unexploded ordnance and mines,” according to Oleksandr Galushchenko, director of the biosphere reserve. The larger mammals that constantly move around the reserve – wolves, deer, brown bears, lynx, elk, and recently reintroduced bison – are at particular risk, he says.”-Samy“The forests in the zone remain a radioactive tinderbox that, in the event of fires, could send radioactive isotopes on the winds towards Kyiv. The risks of that happening are now much greater, says the UNCG’s forest campaigner Yehor Hrynyk. With fire-fighting equipment looted and much of the exclusion zone dangerous for firefighters to enter, some 65,000 acres has burned since the invasion, and fires continue to smolder in underground peat.”-Colin“Many industrial plants are damaged or abandoned;wrecked sewage works gush their contents into rivers; damaged pipelines are filling wetlands with oil; and toxic military scrap is spread across the land.”- Flavio“A particular concern is the many coal mines abandoned after 2014. With pumping of water halted, they have so far released some 650,000 acre-feet of polluted mine water into the environment,...

• Single Use Plastics

  My AP Biology Thoughts Unit #: 8- Disruptions to Ecosystems---------------------------------------------------------------------------------------------------------------------------------------------------EPISODE TITLE: Single Use PlasticsJaiden: Welcome to My AP Biology Thoughts podcast, our names are Jaiden, Adam, and Reena and we are your hosts for this episode called Unit 8, Human Stupidity and Single Use Plastics. Today we will be discussing how single use plastics cause disruptions to the ecosystem and how it relates to the AP Biology Curriculum. The Podcast will be broken up into three segments. The first segment will show the general overview of single-use plastics and the second segment will show how these plastics impact the environment and why it relates to the AP Biology Curriculum. Finally, segment three will discuss how we can contribute and reduce single use plastics.Segment 1: Overview of TopicPlastic pollution has become one of the most pressing environmental issuesAccording to the Environmental Protection Agency, Americans generated 35.7 million tons of plastic in the United States. Single use plastics are plastics that are used for a brief period of time, before they are thrown away. These include plastic straws, spoons, bottles, and bagsMicroplastics are extremely small pieces of plastic debris. They are generally about five millimeters, or approximately the diameter an eraser on a #2 pencils, in length to be considered microplasticsSegment 2: Just how much harm is plastic causing Some plastics such as Chlorinated plastics is harmful for the soil around it along with water sources making it harder for organisms to growIt takes 1,000 years for a plastic bag to degrade in a landfill. However, the plastic does not degrade completely but instead becomes microplastics that absorb toxins and continue to pollute the environment.An estimated 13 million plastic tons are thrown into the ocean each These small plastic particles may harm our health once they have entered our bodies. Plastic products contain chemical additives. A number of these chemicals have been associated with serious health problems such as hormone-related cancers, infertility and neurodevelopmental disorders like ADHD and autism.There are now 5.25 trillion macro and micro pieces, weighing up to 269,000 tonnes. This is because every day, around 8 million pieces of plastic make their way into our oceans.Unlike some other kinds of waste, plastic doesn't decompose. That means plastic can stick around indefinitely, wreaking havoc on marine ecosystems. Some plastics float once they enter the ocean, though...

• Bee Conservation

  My AP Biology Thoughts Unit 8 Ecology EPISODE TITLE: Conservation of BeesWelcome to My AP Biology Thoughts podcast, my name is Alex, here with Raelynn and Samiyah and we are your hosts for today’s episode, coming from Unit 8 - our Ecology unit. Today we will be discussing bee conservation.Why are bees important to the environment?According to the US Department of Agriculture: “One out of every three bites of food in the United States depends on honey bees and other pollinators. Honey bees pollinate $15 billion worth of crops each year, including more than 130 fruits and vegetables. Managed honey bees are important to American agriculture because they pollinate a wide variety of crops, contributing to food diversity, security and profitability.”Pollinators - support plant populationsFood crops as well as wild plantsWhy are bee populations declining? “Declines in bumble bee species in the past 60 years are well documented in Europe, where they are driven primarily by habitat loss and declines in floral abundance and diversity resulting from agricultural intensification.” (According to researchers from the University of Stirling)loss of habitats because of farming + urbanizationHabitat fragmentation can impact surviving populations through genetic isolation (which causes inbreeding and makes population less genetically diverse, making them more susceptible to diseases)University of London (an issue of Apidologie): habitat loss is the “most universal and high impact factor driving bee declines.”https://www.ehn.org/monoculture-farming-is-not-good-for-the-bees-study-2639154525.html https://abcnews.go.com/International/monoculture-farming-modern-day-agriculture-killing-bees-scientists/story?id=80536659 Climate ChangeUniversity of London (an issue of Apidologie): Change in temperature and weather patterns due to climate change can significantly impact bee populationsAdditionally, loss of habitat due to rising sea levels can also cause negative impacts statsUniversity of Maryland: October 2018 - April 2019:

• Rhino Poaching in South Africa

  My AP Biology Thoughts Unit 8 Ecology EPISODE TITLE: South African Rhino PoachingWelcome to My AP Biology Thoughts podcast, my name is Keenan Wallace and I am your host for this episode called Unit 8 Ecology-Threatened Rhinos in South Africa. Today we will be discussing South African Rhino Poaching and how it relates to the AP Biology Curriculum. Segment 1: Overview of Rhino Poaching numbers poached rising in recent years:13 Rhinos poached in 2007, peaked in 2015 1175 Rhinos killed in south africa in 2015 (more than 3 a day), number poached has since declined with 394 killed in 2020Rhino population has decreased from 1 million in the 1800s to only 27,000 in the wild today.Rhinos are a keystone species: They play an integral role in their ecosystem and many other species in the ecosystem depend on their presenceSegment 2: Evidence that supports dangers of rhino poaching Rhinos are so large that they actually Geo-form: change the land around themRhinos often wallow in mud to keep cool and ward off insects. This helps maintain waterholesWhen the rhinos get out they track the fertile, nutrient rich soil that accumulates in waterholes far and wide, distributing the nutrients. Rhino dung supports other species and food chainsRhino dung fertilizes soilDung beetles lay their eggs in rhino dung, which also supports species that eat the beetle larvaeA number of bird species rely on Rhino dung for insects and seeds. Rhinos support fly and tick species as well as animals that eat them, like terrapins (a kind of turtle) and oxpeckers (the iconic symbiotic relationship)Keep grass short, allowing plant species that can’t survive among long grass to thrive.Segment 3: Connection to the Course Without rhinos, all of these roles would be left unfilled and with its foundation gone the ecosystems would begin to collapse. (keystone species)When you hear about rhino conservation, this is why it matters. Thank you for listening to this episode of My AP Biology Thoughts.
