Evolutionary History, Habitat Disturbance Regimes, and Anthropogenic Changes: What Do These Mean for Resilience of Pacific Salmon Populations?

Ecology and Society, 2009
Because resilience of a biological system is a product of its evolutionary history, the historical template that describes the relationships between species and their dynamic habitats is an important point of reference.

Habitat disturbance and hydrological parameters determine the body size and reproduction strategy of alluvial ground beetles

ZooKeys, 2011
Environmental variability is the main driver for the variation of biological characteristics (life-history traits) of species. Therefore, life-history traits are particularly suited to identify mechanistic linkages between environmental variability and ...

The Influence of Urbanization and Fire Disturbance on Plant-floral Visitor Mutualistic Networks

Diversity, 2020
The biodiversity loss resulting from rising levels of human impacts on ecosystems has been extensively discussed over the last years. The expansion of urban areas promotes drastic ecological changes, especially through fragmentation of natural areas ...

The timing of life history events in the presence of soft disturbances [PDF]

Journal of Theoretical Biology, 2016
We study a model for the evolutionarily stable strategy (ESS) used by biological populations for choosing the time of life-history events, such as arrival from migration and breeding. In our model we account for both intra-species competition (early individuals have a competitive advantage) and a disturbance which strikes at a random time, killing a ...

Natural Disturbances Regime as a Factor of Korean Pine-Broadleaved Forest Stand Shaping in the South of the Russian Far East [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2015
Using dendroecological approach we reconstructed disturbance history of a mixed Korean pinebroadleaved stand in the south of the Russian Far East. Our results show that during the last two centuries there were no mass disturbances, which may lead to ...

Nitrous oxide fluxes from tropical peat with different disturbance history and management [PDF]

Biogeosciences, 2012
Tropical peatlands are one of the most important terrestrial ecosystems in terms of impact on the atmospheric greenhouse gas composition. Currently, greenhouse gas emissions from tropical peatlands following disturbances due to deforestation, drainage or

Intermediate Anthropogenic Disturbances Boost Taxonomic and Phylogenetic Diversities but Reduce Functional Diversity in Subtropical Forests of Eastern China

Plants
Anthropogenic disturbances significantly impact plant biodiversity in subtropical forests. While prior research has primarily concentrated on taxonomic diversity, other dimensions of biodiversity, such as phylogenetic and functional diversities, remain ...

Historical exposure to wastewater disposal reinforces the stability of sediment bacterial community in response to future disturbance

Blue-Green Systems, 2021
Given that long-term treated wastewater discharge may alter the microbial community of the recipient coast, it is important to evaluate whether and how the community's stability is impacted.

TYPE OF DISTURBANCE AND ECOLOGICAL HISTORY DETERMINE STRUCTURAL STABILITY

Ecological Applications, 2007
This study aims to reveal whether complexity, namely, community and trophic structure, of chronically stressed soil systems is at increased risk or remains stable when confronted with a subsequent disturbance. Therefore, we focused on a grassland with a history of four centuries of patchy contamination.

“It is not important whether he hates or not. Muselmänner disturbed him”– a Category of Disturbance in the Narrations about a Muselmann in the Literature of the Shoah

Poznańskie Studia Polonistyczne. Seria Literacka, 2015
In the literary recollections of camp survivors the figure of the Muselmann is a recurring motif. The author puts forward a thesis about the existence of a dominating, prototypical narration about a Muselmann, which occurs not only in literary texts but ...
