What is Biodiversity?01:19

What is Biodiversity?

34.0K
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

27.2K
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...

Biodiversity and Human Values

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Relationship Formation

46.3K
What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Ending Relationships

205
The dissolution of intimate relationships presents complex emotional and psychological challenges, particularly when emotional bonds are strong, the relationship is long-standing, and perceived alternatives are limited. This distress often intensifies in romantic breakups, where the initiator may experience greater turmoil than the rejected partner. Contributing factors include residual attachment, guilt over causing pain, and uncertainty about how to manage the situation. The stress is further...

Pharmacokinetic–Pharmacodynamic Relationship: Duration of Dose-Effect Relationship

9
For drugs producing a quantal response, onset occurs when plasma concentration reaches a minimum effective level (Cmin). The drug's action duration depends on how long the plasma concentration remains above Cmin.Two primary factors influence this duration: dose size and the rate of drug removal from the action site. Both depend on the drug's redistribution to poorly perfused tissues and elimination processes. A larger dose promotes rapid onset and prolongs the effect's duration.Consider a...

Summary
This summary is machine-generated.

Parasites significantly impact ecosystem functioning and biodiversity, yet their role is often overlooked. Incorporating parasite-host interactions into biodiversity and ecosystem functioning (BD-EF) research is crucial for a comprehensive understanding.

Area of Science:

  • Ecology
  • Environmental Science
  • Parasitology

Background:

  • Species interactions are key drivers of ecosystem functioning and biodiversity.
  • Biodiversity and Ecosystem Functioning (BD-EF) research has largely excluded the significant role of parasitism.
  • Parasites are ubiquitous and can influence ecosystems through various mechanisms.

Purpose of the Study:

  • To highlight the importance of parasite-host interactions in BD-EF research.
  • To propose the integration of parasitism into existing BD-EF frameworks.
  • To address the challenges in predicting the net effects of parasites on ecosystem processes.

Main Methods:

  • Review of existing literature on species interactions and ecosystem functioning.
  • Analysis of potential mechanisms through which parasites affect ecosystem processes.
  • Conceptual framework development for integrating parasitism into BD-EF.

Main Results:

  • Parasites can alter ecosystem processes by affecting host abundance.
  • Parasites may enhance trait diversity by suppressing dominant species or increasing within-host diversity.
  • The net effect of parasites on ecosystem function is complex and challenging to predict.

Conclusions:

  • Parasite-host interactions are a critical, yet understudied, component of BD-EF.
  • Integrating parasitism into BD-EF research is essential for a complete ecological understanding.
  • Future research should focus on quantifying the diverse impacts of parasites on ecosystems.
