Overexploiting sea otters resulted in cascade effects which destroyed kelp forest ecosystems. Overexploitation of species can result in knock-on or cascade effects. This can particularly apply if, through overexploitation, a habitat loses its apex predator. Because of the loss of the top predator, a dramatic increase in their prey species can ...
Included an essay from Evelyn about soils: Terra, a Philosophical Essay of Earth, being a Lecture in Course. 1706 Silva Fourth Edition, now spelt Silva, contained new sections Dendrologia, Pomona; Or, An Appendix concerning Fruit-Trees in relation to CIDER and Kalendarium Hortense. This was the last edition during Evelyn's lifetime.
Deforestation is a cause of human-induced habitat action destruction, by cutting down habitats of different species in the process of removing trees. Deforestation is often done for several reasons, often for either agricultural purposes or for logging , which is the obtainment of timber and wood for use in construction or fuel. [ 7 ]

Planting trees in tropical climates with wet seasons has another advantage. In such a setting, trees grow more quickly (fixing more carbon) because they can grow year-round. Trees in tropical climates have, on average, larger, brighter, and more abundant leaves than non-tropical climates.
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
Furthermore, when seed predation is down, trees with large seeds begin to completely dominate those with small seeds, changing the balance of plant life in an area. [ 4 ] Predatory large mammals are important for increasing overall biodiversity by making sure that smaller predators and herbivores do not become overabundant and dominate.
Joseph Connell published his hypothesis in 1970 in Dynamics of Populations. [2] Unlike Janzen, Connell proposed experiments that focused on the key prediction that exclusion of host-specific predators would cause a decrease in diversity as tree species with greater establishment or competitive ability formed low-diversity seedling and sapling communities where dominance was concentrated in a ...
