What is Conservation Biology?01:57

What is Conservation Biology?

24.4K
Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Conservation of Small Populations02:04

Conservation of Small Populations

17.4K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Conserved Binding Sites01:49

Conserved Binding Sites

5.2K
Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

Conservation of Protein Domains Over Different Proteins02:26

Conservation of Protein Domains Over Different Proteins

14.6K
Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Non-conservative Forces01:17

Non-conservative Forces

9.9K
Non-conservative forces are dissipative forces such as friction or air resistance. These forces take energy away from a system as it progresses. Unlike conservative forces, non-conservative forces do not have potential energy associated with them. This is because the energy is lost to the system and cannot be turned into useful work later.
Also unlike their conservative counterparts, they are path-dependent; where the object starts and stops does matter. For example, a grinding wheel applies a...

Conservation of Energy00:54

Conservation of Energy

11.3K
The terms 'conserved quantity' and 'conservation law' have specific scientific meanings in physics, which differ from the meanings associated with their everyday use. For example, in everyday usage, water could be conserved by not using it, by using less of it, or by re-using it. However, in scientific terms, a conserved quantity of a system stays constant, changes by a definite amount that is transferred to other systems, and is converted into other forms of that...

Area of Science:

  • Ecology
  • Conservation Biology
  • Environmental Science

Background:

  • Conservation strategies are frequently challenged as pessimistic and ineffective for halting biodiversity loss.
  • Proposed new conservation agendas often lack empirical support.
  • Existing research may be biased, but its role in documenting biodiversity impacts is significant.

Purpose of the Study:

  • To empirically assess the actual practices and contributions of conservation research over the last 15 years.
  • To evaluate the claims that current conservation strategies are inadequate.
  • To determine the necessity and sufficiency of novel conservation approaches.

Main Methods:

  • Systematic review of 12,971 papers from leading conservation journals.
  • Analysis of published research to identify conservation actions and their outcomes.
  • Assessment of biases within conservation research.

Main Results:

  • Conservation research significantly contributes empirical evidence of human impacts on biodiversity.
  • A wide array of conservation tools, beyond protected areas, are actively promoted.
  • Evidence of successful biodiversity comebacks is documented in the literature.
  • Conservation research is influenced by specific biases.

Conclusions:

  • Current conservation research plays a crucial role in documenting biodiversity threats and successes.
  • A diverse toolkit of conservation interventions is already in use and promoted.
  • The development of novel conservation agendas is neither necessary nor sufficient to halt biodiversity loss.
  • Existing conservation efforts, supported by empirical research, are vital.
