Threats to Biodiversity

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

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.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Ecological Disturbance

Ecological Disturbance

An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

Ecological Succession

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...

The Carbon Cycle

The Carbon Cycle

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Summary

This summary is machine-generated.

Forests are changing faster than expected due to climate change and other factors. Unmanaged forest growth may help slow these climate-driven changes, preserving biodiversity and ecosystem services.

Background:

Climate change is accelerating ecosystem shifts, impacting forest services and biodiversity.
Multiple drivers, including climate, disturbance, and stand legacies, influence forest dynamics.
The combined effects of these drivers on forest change remain poorly understood.

Purpose of the Study:

To assess forest dynamics over 28 years in Berchtesgaden National Park (BGNP), Germany.
To quantify spatiotemporal patterns of forest change and identify key drivers.
To investigate the acceleration of forest dynamics and its relationship with climate and legacies.

Main Methods:

Analysis of high-density forest inventory data from 3759 permanent sample plots (132,866 tree records).
Utilized semi-variograms to analyze spatial patterns of change.
Employed boosted regression trees to assess the impact of 30 covariates on forest structure and composition indicators.

Main Results:

BGNP forests became denser, structurally complex, and species-rich over 28 years.
Forest structure changes were more spatially correlated than species composition changes.
Change rates accelerated over time, with climate and legacies as primary drivers, exhibiting diverging impacts.

Conclusions:

Evidence of accelerating forest dynamics in Alpine mountain forests, with significant biodiversity and ecosystem process implications.
Increasing temperatures correlate with accelerated forest change, but high legacy levels can dampen this effect.
Unmanaged forest development towards old-growth conditions may counteract climate-driven acceleration, preserving ecosystem functions.
