- 熱帯農業
背景:
- 商業作物が多い熱帯地域では 生物多様性と生態系機能の回復に関する 知識の欠如が顕著です
- 国連の生態系修復十年では 効果的な修復戦略の緊急性が強調されています
研究 の 目的:
- パーム油の景観における生物多様性と生態系の機能に対する樹木島の影響を評価する.
- 樹の島規模と生態学的改善の関係を評価する.
- オイルパームの収穫量に 樹木を豊かにする効果を 調べるため
主な方法:
- 5年間の大規模な生態系修復実験が パーム油の景色で実施されました
- 52の木の島が確立され,監視された.
- 10の生物多様性指標と19の生態系機能指標が評価されました.
- オイルパームの収穫量は 景観スケールで測定されました
主要な成果:
- 生物多様性と生態系機能の指標は,従来管理されているオイルパームと比較して,木の島で高かった.
- 植物の構造の変化に結びついた 多様性の増加に繋がった.
- 景観を樹木で豊かにすることは 石油パームの総生産量に悪影響を及ぼさなかった.
結論:
- オイルパームの景観を 樹木の島で豊かにすることは 生態系の回復戦略です
- このアプローチは生物多様性と生態系の多機能性を高めることができます.
- 現存する森林の保護は不可欠であり,この復元方法によって置き換えられるべきではありません.

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Keystone Species
21.8K
Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a...

What is Biodiversity?
27.5K
Biodiversity describes the variety of living things at multiple organizational levels: genetic, species and ecosystem diversity. Species diversity includes all branches of the evolutionary tree from single-celled prokaryotic organisms, bacteria, and archaea, to the eukaryotic kingdoms: plants; animals; fungi; and protists. To date, there have been about 1.75 million species identified, and new species are discovered every week.

Threats to Biodiversity
22.5K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Green Algae
62
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...
