まとめ
気候の温暖化は,ヨーロッパの山岳地帯で植物の種を上昇させている. 北極温帯の山頂では種が増えたが,地中海の山頂では水資源の減少により種が減り,固有の植生を危険にさらした.
科学分野:
- エコロジー エコロジー エコロジー
- 植物学 植物学
- 気候変動科学 気候変動科学
背景:
- 気候の温暖化は,種がより高い標高に向かって範囲をシフトさせる原因となっている.
- 標高変化の証拠は,しばしば歴史的遺跡の再調査に依拠する.
- 標準化されたモニタリングネットワークは,進行中の生態学的変化を追跡するために不可欠です.
研究 の 目的:
- 欧州の山脈における血管性植物種の豊かさの最近の変化を評価する.
- 標高上の種の移転と,その影響が山頂の植物に及ぼす影響を分析する.
- 気候の動向による種豊かさの変化における地域差異を特定する.
主な方法:
- 主要なヨーロッパの山脈を横断する標準化された監視ネットワークを利用した.
- 2001年から2008年までの血管性植物種の富に関するデータを収集した.
- 北極温帯と地中海の山岳地域における種豊かさの変化を比較した.
主要な成果:
- 血管系植物種は,平均的な上昇斜面の範囲のシフトを示しました.
- サミット・フローラの種豊かさは,北極温帯の山々 (+3.9種) で増加した.
- サミット・フローラの種豊かさは,地中海山脈で減少した (-1.4種).
結論:
- 標高上の種の移動は,ヨーロッパ全土の山頂の植物の豊かさに対照的な影響を及ぼします.
- 南ヨーロッパにおける水資源の減少は,地中海の山岳植生に悪影響を及ぼす可能性が高い.
- 継続的な傾向は,欧州の山岳植物の全体的な減少,特に固有の種の減少につながる可能性があります.

Threats to Biodiversity
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...
Global Climate Change
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
Introduction to Plant Diversity
From Water to Land
Ecological Succession
Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...
What is Biodiversity?
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.
Diversity of Protists IV
Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...
