Relationships between organisms can take several forms. There are symbiotic relationships where two species live together, including mutualism where both benefit, commensalism where one benefits and the other is unaffected, and parasitism where one harms the other. There is also predation where one organism preys on another. Examples of mutualism include lichens, which are a symbiotic combination of algae and fungi. Commensalism can occur when one species benefits from another without affecting it, while parasitism involves one organism harming the other for its own benefit.
Ecological Interactions - Mutualism, Commensalism & NeutralismRahul M. Prathap
Ecological interactions are the effects an organism have on another in an ecosystem. This slide describes Mutualism, Commensalism and Neutralism with examples.
Insects are a class of invertebrates within the arthropod phylum that have a chitinous exoskeleton, a three-part body, three pairs of jointed legs, compound eyes and one pair of antennae.

Ecological interactions form the backbone of an ecosystem. It helps in maintaining the
dynamic equilibrium of an ecosystem. All organisms are linked to at least one other species in a
variety of critical ways, for example, as predators or prey, or as pollinators or seed dispersers with the
result that each species is embedded in a complex network of interactions. Consequently, the
extinction of one species can lead to a cascade of secondary extinctions in ecological networks.
Moreover, interactions between species can lead to ‘community closure’ after the loss of a species,
with the result that a locally extinct species cannot re-establish itself if it is reintroduced. Many
ecological interactions involve flagship species and keystone species as in the case of Macaca
silenus & Cullenia exarillata. Then some interactions like mycorrhiza help in nitrogen fixation.
Strategies like predation reduce the loss of vegetation through grazing. Interaction can be either intraspecific or interspecific. Interactions between individuals of the same species
and those between individuals of different species are called intra- & interspecific interactions.

for a common prey for intraspecific interaction.
Mutualism describes an interaction that benefits both species. A well-known example exists in the mutualistic relationship between alga and fungus that form lichens. The photosynthesizing alga supplies the fungus with nutrients and gains protection in return. The relationship also allows lichen to colonize habitats inhospitable to either organism alone. In rare cases, mutualistic partners cheat. Some bees and birds receive food rewards without providing pollination services in exchange. These "nectar robbers" chew a hole at the base of the flower and miss contact with the reproductive structures.
Both species involved in the interaction are benefited. These interactions take place in three patterns:
Facultative mutualism – Species survive on their own under favorable conditions
Obligate mutualism – One species is dependent for survival on the other
Diffusive mutualism – One entity can live with multiple partners
These relationships have three purposes:
Defensive mutualism
Trophic mutualism
Dispersive mutualism

15.1 Parasites Draw Resources from Host Organisms
Parasitism is a type of symbiotic relationship between organisms of different species. One species—the parasite—benefits from a prolonged, close association with the other species—the host—which is harmed. Parasites increase their fitness by exploiting host organisms for food, habitat, and dispersal. Although they draw nourishment from the tissues of the host organism, parasites typically do not kill their hosts as predators do. However, the host may die from secondary infection or suffer reduced fitness as a result of stunted growth, emaciation, modification of behavior, or sterility. In general, parasites are much smaller than their hosts, are highly specialized for their mode of life, and reproduce more quickly and in greater numbers than their hosts.
The definition of parasitism just presented may appear unambiguous. But as with predation the term parasitism is often used in a more general sense to describe a much broader range of interactions (see Section 14.1). Interactions between species frequently satisfy some, but not all, parts of this definition because in many cases it is hard to demonstrate that the host is harmed. In other cases, there may be no apparent specialization by the parasite or the interaction between the organisms may be short-lived. For example, because of the episodic nature of their feeding habits, mosquitoes and hematophagic (blood-feeding) bats are typically not considered parasitic. Parasitism can also be used to describe a form of feeding in which one animal appropriates food gathered by another (the host), which is a behavior termed cleptoparasitism (literally meaning “parasitism by theft”). An example is the brood parasitism practiced by many species of cuckoo (Cuculidae). Many cuckoos use other bird species as “babysitters”; they deposit their eggs in the nest of the host species, which raise the cuckoo young as one of their own (see Chapter 12 opening photograph). In the following discussion, we use the narrower definition of parasite as given in the previous paragraph, which includes a wide range of organisms—viruses, bacteria, protists, fungi, plants, and an array of invertebrates, among them arthropods. A heavy load of parasites is termed an infection, and the outcome of an infection is a disease.
Parasites are distinguished by size. Ecologically, parasites may be classified as microparasites and macroparasites. Microparasites include viruses, bacteria, and protists. They are characterized by small size and a short generation time. They develop and multiply rapidly within the host and are the class of parasites that we typically associate with the term disease. The infection generally lasts a short time relative to the host’s expected life span. Transmission from host to host is most often direct, although other species may serve as carriers.

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

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.
