High redundancy model ecology
WebFeb 17, 2024 · The mechanism underlying this pattern is suggested as a combination of two factors, high levels of disturbance restricting species to all but the most disturbance tolerant, and low levels of disturbance allowing increased competitive exclusion ( Mouillot et … WebIn ecosystems with high redundancy, losing a species (which lowers overall functional diversity) will not always lower overall ecosystem function due to high functional overlap, and thus in this instance it is most important to conserve a group, rather than an individual.

Webredundancy, in the context of ocean biogeochemistry, has previously been defined as the ‘ability of one microbial taxon to carry out a process [i.e. a function] at the same rate as another under the same environmental conditions’ (Allison & Martiny, 2008). In an oceanic context, ecological redundancy could similarly be defined as ‘ability

Resilience-based management has become a common tool for environmental managers (Anthony et al., 2015; Berkes, 2012; McLeod et al., 2024; McLeod & Leslie, 2009).Although preserving biodiversity continues to be a paramount goal of management agencies, maintaining the ecological functioning of the ecosystems …
WebJun 23, 2024 · In areas with more favourable environmental conditions (e.g. high precipitation and warm temperatures), which permit the coexistence of a greater number of species with contrasting ecological strategies, functional redundancy may be either high or low as multiple ecological strategies may be represented by many species (high … church christmas programs 2021 near meWebAug 19, 2011 · The relationship between species diversity and FD is also influenced by the sensitivity of the FD metric to functional differences between species.
