Plants such as an infertile cotton strain have been made in laboratories using GURT. [1] Genetic use restriction technology (GURT), also known as terminator technology or suicide seeds, is designed to restrict access to "genetic materials and their associated phenotypic traits." [2] The technology works by activating (or deactivating) specific ...
Hawaii has a growing invasive species crisis affecting the islands' endangered plants and animals, overall environmental and human health, and the viability of its tourism and agriculture-based economy. Invasive species occur globally, but Hawaii is more susceptible to invasive species because they are islands.
In Apollodorus' account, Heracles had to go to the island of Erytheia in the far west. On the way he became so frustrated at the heat that he aimed an arrow at the Sun. The sun-god Helios, impressed by his audacity, gave Heracles the golden cup that Helios used to sail across the sea from west to east each night. Heracles took the cup and rode ...
The plant species in this ecosystem are highly diverse, yet the majority of these species are obligate seeders, that is, a fire will cause germination of the seeds and the plants will begin a new life-cycle because of it. These plants may have coevolved into obligate seeders as a response to fire and nutrient-poor soils. [43]
Biological pest control. Syrphus hoverfly larva (below) feed on aphids (above), making them natural biological control agents. Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. [1]
Weed control is a type of pest control, which attempts to stop or reduce growth of weeds, especially noxious weeds, with the aim of reducing their competition with desired flora and fauna including domesticated plants and livestock, and in natural settings preventing non native species competing with native species.

A strawberry aggregate accessory fruit damaged by a mouse eating the seeds (achenes). Seed predation, often referred to as granivory, is a type of plant-animal interaction in which granivores (seed predators) feed on the seeds of plants as a main or exclusive food source, [1] in many cases leaving the seeds damaged and not viable.
Around 90% of the cassowary diet consists of fruit, although all species are opportunistic omnivores, and take a range of other plant foods, including shoots and grass seeds, in addition to fungi, eggs, invertebrates, carrion, and small vertebrates like fish, rodents, small birds, frogs, lizards, and snakes.
