Rainforests of Sumatra and Borneo /Integrated, Stage 3 Unit Barbara Schaffer
A unit which focuses on the global causes and consequences of deforestation in Borneo and Sumatra and the way that individuals and groups can act to protect the rainforest.
Predator-prey relations refer to the interactions between two species where one species is the hunted food source for the other. The organism that feeds is called the predator and the organism that is fed upon is the prey.
Whale Shark The largest of all sharks and the largest living fish, the whale shark is one of the most dramatic views of the ocean. Its large size, distinctive patterns and its enormous mouth make it instantly recognizable and can be commonly seen wandering near the surface in tropical and subtropical waters around the world. Their diet is based mainly on plankton, but also regularly feed on small schooling fish and squid. Unlike basking sharks, which simply filter vast amounts of water as they swim, whale sharks actively suck their prey before filtering efficiently and are sometimes seen in groups, feeding on high concentrations of food. Regularly appear in the same places at specific times of the year, probably to capitalize on plankton blooms and events such as coral spawning.
Geographic LocationThey are found throughout the Pacific, Atlan.docxlaquandabignell
Geographic Location:
They are found throughout the Pacific, Atlantic, and Indian Oceans. In the Pacific, their range extends as far north as Alaska and south beyond the southernmost tip of New Zealand.
In the Atlantic, they can be found as far north as Norway and the Arctic Circle and south to the tip of Africa. They are mainly pelagic (open ocean) wanderers but migrate to tropical and subtropical coastal regions to mate and nest.(
Osborne,2015)
In 1982, scientists estimated that there were 115,000 adult female leatherback sea turtles worldwide. Recent estimates have placed the number between 20,000 and 30,000 (Singh,2007).
Trends in Population:
The global population for this species was estimated to be 115,000 adult females in 1982. By 1996 this had been revised down to about 30-40,000. Leatherback populations in the Pacific and Indian Oceans have undergone dramatic declines in the past forty years. For example, the nesting colony at Terengganu, Malaysia went from more than 3,000 females in 1968, to 20 in 1993, to just 2 in 1993 - there are no signs of recovery.
Similar scenarios have occurred in Indonesia, Sri Lanka, Thailand, and Mexico. Numbers of females recorded at four formerly major Pacific rookeries have declined to about 250 in Mexico, 117 in Costa Rica, two in Malaysia, and fewer than 550 in Indonesia(Anonymous, 2006)
Reproduction:
Leatherbacks mate offshore in shallow waters near the nesting area. The females dig their flask-shaped nests at night on sloping sandy beaches backed by vegetation. Six clutches can be laid in a season, with a 10-day period between nesting. The females may renest up to 7 miles from the first nest. An average clutch contains 80 to 85 eggs and incubation takes from 55 to 74 days. The 3-inch hatchlings emerge at night and head toward the ocean. The turtles reach sexual maturity at 6 to 10 years of age; the females nest every second or third year.
In the U.S., nesting occurs from about March to July. Female leatherbacks nest an average of 5 to 7 times within a nesting season, with an observed maximum of 11 nests. Most leatherbacks remigrate to their nesting beaches at 2 to 3-year intervals. (Department of energy and environmental protection, 2014)
Threats:
1-
Marine pollution
It is the greatest threat for leatherback sea turtles, while they accidentally eat balloons and plastic bags floating in the water which they mistaken as jellyfish.
(Leigh,2015)
2-
Overharvesting and illegal:
Egg collection on many turtle nesting beaches is a very serious threat, especially in Southeast Asia where a culture of legal egg collection leads to the removal of tens of thousands of eggs. This practice has contributed to the local extinction of leatherbacks in Malaysia. Within the last several decades extensive egg collection and the killing of adult turtles in Indonesia has resulted in huge population declines throughout the region. Despite protective legislation, many eggs produced each year in Central America are.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2. The future of marine turtles is grim…6 of the 7 species are Endangered or Critically Endangered. All 7 are listed on Appendix 1 of CITES making their trade internationally prohibited among the 166 CITES member nations. Even though the species are protected they still face multiple threats that are causing their numbers to decline at an alarming rate. This brief presentation aims to introduce you to these 6 species that may face extinction in the very near future if we, as co-inhabitants of this earth, do not share in the responsibility of their protection.
3. The KEMPS RIDLEY turtle is the most endangered species of marine turtle. It nests only on a small area of coastline in the Gulf of Mexico. They can weigh up to 40kg and have an average length of 69cm making them, along with the Olive Ridley turtle, the smallest species. The females are migratory, swimming vast distances to reach nesting grounds every 1-3 years. Females are able to reproduce at 12 years of age. Their carapace is olive grey and they have a white/yellow underbelly. Nesting occurs in broad daylight and only on one 20km stretch of beach on the Gulf on Mexico. Their survival hangs in the balance primarily due to over harvesting of their eggs and commercial fishing fleets. Even though some fishing fleets use turtle excluder devices their population has not been able to rebound. This species feeds mostly on invertebrates thereby playing an important role in open ocean and coastal ecosystems. There are only about 1,000 of these Critically Endangered breeding females left in the wild
4. Although the HAWKSBILL turtle is Critically Endangered and protected under CITES there is still an excessive amount of trade in products made with the shell of this turtle. This is thought to be the primary cause of their decreasing population trend. There shell is beautifully coloured with elaborate patterning. The scutes on the carapace are very unique with their hard, overlapping boney plates. This species is the only source of commercial tortoise shell ,often used to make jewellery and ornaments. There is a strong demand for these products in Japan as well as South and East Asia They weigh between 46-60kg and are usually less than 1m in length. Hawksbill turtles are primarily spongivorous. When they dislodge pieces from the coral it provides reef fish with food. They support healthy reefs by controlling sponges which would out –compete reef building coral for space. According to the IUCN there has been an 87% decline in the number of mature females nesting in the last 3 turtle generations. Other threats include excessive egg collection, slaughter for meat for human consumption and shark bait. Destruction of nesting and foraging habitat, hybridization of Hawksbill with other species of marine turtles when populations are very low, entanglement and ingestion of marine debris and oil pollution
5. The OLIVE RIDLEY turtle is the most abundant marine turtle and is listed as Endangered on the IUCN’s Red List and is protected under CITES. It nests on 5 beaches in Mexico, Costa Rica and North East India. On the beaches of Orissa in India it is estimated that 120,000 have been killed in the last 10 years. The genus of Ridley turtles (lepidochelys) split into 2 species - the Kemp’s Ridley and the Olive Ridley. They look quite similar except the Olive Ridley has a deeper body and the edges of its rusty coloured carapace are upturned. Average length is 75cm and weight is approximately 45kg. Primary threats include unsustainable egg harvest, illegal poaching of adult turtles, bycatch in fisheries (trawl, longlines, purse seines, gill net, hook and line) and habitat degredation. Fibropapilloma, a herpes infection found in many sea turtles but not believed to be prevalent in Olive Ridley’s, has been found in Costa Rica. It is thought that this herpes infection may be caused by run-off from land causing marine pollution and a weakening their immune systems
6. The LEATHERBACK turtle is listed as Critically Endangered and is protected under CITES. Based on information provided by the IUCN, global populations are in decline with the population in Costa Rica dropping from 1,646 nests to 500 nests on the main nesting beach on the Pacific Coast in just a little over a decade. Their main threats have been the prolonged unsustainable harvest of eggs and their capture by oceanic fisheries. In some areas harvesting of eggs and poaching of adults has removed more than 95% of the clutches. Longlines and driftnets as well as oceanic pollution by plastics are significant threats as well. Phthalates have been found in the yolks of Leatherback eggs. Leatherbacks eat jellyfish and often mistake plastic bags as this food source, ingestion results in a slow painful death due to their one way digestive system and inability to regurgitate. This causes them to starve To death. Populations may be as low as 34,000 nesting females
7. The GREEN turtle is listed as Endangered and is also protected under CITES. According to the IUCN the annual number of nesting females has declined by 48-57% over the last 3 turtle generations. They are harvested for meat in many tropical countries, it is thought that 100,000 are killed annually in the Indo-Australian archipelago and 30,000 in Baja California for this reason alone. In some areas they are suffering from potentially lethal tumours, this is thought to be due to increasing levels of oceanic pollution. These turtles get their name from the greenish color of their shell and the fat deposits around their internal organs. They are 80-150cm in length and can weigh up to 130kg. Green turtles are the only truly herbivorous marine turtle, feeding mostly on sea grasses and algae. The most detrimental human threat may be over harvesting of eggs and poaching of adults. Mortality associated with entanglement in fishing nets is the primary incidental threat. There are an estimated 203,000 left worldwide.
8. The LOGGERHEAD turtle is Endangered and protected under CITES. They are highly migratory and often get caught up in fishing nets and lines. Their shells are used to make paddle boats in Honduras. This species of turtle is one of the largest and carries more encrusting organisms on its carapace than any other marine turtle. Their shell is reddish brown and the underbelly is light yellow This turtle is carnivorous, feeding mainly on molluscs and impressively, also feeds on the almost impenetrable queen conch. There are thought to be more than 60,000 nesting females. Their main cause of mortality is thought to be the result of fishing bycatch, with abandoned driftnets continuing to drown these turtles every day. Before the introduction of turtle excluder devices, about 50,000 were killed in shrimp nets in the Gulf of Mexico and the Atlantic Ocean.
9. The mission of the Canadian Organization for Tropical Education and Rainforest conservation is to provide leadership in education, research, conservation, and the educated use of natural resources in the tropics.
