Threats to Biodiversity01:50

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...

Keystone Species01:39

Keystone Species

21.7K
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...

Ecological Disturbance02:26

Ecological Disturbance

17.2K
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 Succession02:17

Ecological Succession

17.3K
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...

Habitat Fragmentation02:31

Habitat Fragmentation

17.7K
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

Symbiosis00:58

Symbiosis

29.0K
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Area of Science:

  • Agricultural Science
  • Ecology
  • Plant Biology

Background:

  • Invasive alien plant species significantly impact native flora, yet their effects on crop growth mechanisms remain understudied.
  • Understanding direct, indirect, immediate, and legacy effects of invasive plants is crucial for managing invaded croplands.
  • Lantana camara (L. camara) is an invasive plant with poorly understood impacts on subsistence crops.

Purpose of the Study:

  • To investigate the mechanisms by which Lantana camara affects maize and cassava growth.
  • To differentiate between competitive, allelopathic, and indirect plant-plant interaction effects.
  • To assess the role of soil microbial communities in L. camara-crop interactions.

Main Methods:

  • Two pot experiments were conducted using soils from invaded abandoned, invaded cultivated, and non-invaded cultivated fields.
  • Experiment 1: Maize and cassava grown alone or with L. camara, with and without activated carbon to test for allelopathy.
  • Experiment 2: Autoclaved soil inoculated with microorganisms from different soil types to assess microbial community effects.

Main Results:

  • Lantana camara significantly reduced maize growth by 29%; cassava growth was unaffected.
  • No evidence of allelopathic effects from L. camara was found.
  • Microbial inoculation of autoclaved soil enhanced cassava biomass but reduced maize growth, indicating microbial influence.

Conclusions:

  • Lantana camara primarily impacts maize growth through direct competition for resources, not allelopathy.
  • The observed effects are immediate, suggesting that removing L. camara will quickly alleviate negative impacts on maize.
  • Management strategies should focus on timely removal of L. camara to protect maize yields.
