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

17.5K
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 Proteins

14.7K
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

10.0K
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

11.4K
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...

Summary
This summary is machine-generated.

Warming winters threaten the subnivium, a critical winter habitat under snow. Conservation plans and management strategies are needed to protect this vital ecosystem and its species from climate change impacts.

Area of Science:

  • Ecology
  • Climate Change Biology
  • Conservation Science

Background:

  • Warming winters are reducing snowpack depth, duration, and extent in many regions.
  • Most wildlife conservation efforts focus on aboveground species, neglecting the subnivium, a crucial under-snow habitat.
  • The subnivium provides a thermally stable refugium for the majority of overwintering species.

Purpose of the Study:

  • To highlight the ecological importance of the subnivium and the threats it faces due to climate change and human activities.
  • To propose management strategies for conserving subnivium environments and their dependent species.
  • To develop and apply a model for identifying areas vulnerable to subnivium loss.

Main Methods:

  • Literature review on the impacts of altered snow conditions on wildlife.
  • Development of a spatially explicit model to predict subnivium presence.
  • Case study analysis in the Chequamegon National Forest, Wisconsin.

Main Results:

  • Identified that forest management, winter recreation, and activities like road maintenance can negatively impact subnivium conditions through snow compaction.
  • The spatially explicit model identified specific landscapes where human activities pose a threat to subnivium persistence.
  • Demonstrated the utility of modeling approaches for informing subnivium conservation.

Conclusions:

  • Immediate recognition, conservation, and management of the subnivium are crucial due to rapid climate change.
  • Managers should implement regional conservation plans and monitor land cover impacts on subnivium conditions.
  • Controlling activities that disturb and compact snow is essential for subnivium protection.
