Evolutionary Dynamics of Predator-Prey Systems: An Ecological Perspective [PDF]

open access: yes, 1996
Evolution takes place in an evolutionary setting that typically involves interactions with other organisms. To describe such evolution, a structure is needed which incorporates the simultaneous evolution of interacting species.

Nitrogen deposition modulates invasibility and stability of plant communities in microplastic-contaminated wetlands

open access: yesGlobal Ecology and Conservation
Invasive plant species pose a significant threat to the integrity and biodiversity of local ecosystems. Microplastic pollution and nitrogen deposition, as detrimental consequences of human activities, impact the growth of wetland plants.

Regime shift by an exotic nitrogen-fixing shrub mediates plant facilitation in primary succession.

open access: yesPLoS ONE, 2015
Ecosystem invasion by non-native, nitrogen-fixing species is a global phenomenon with serious ecological consequences. However, in the Mediterranean basin few studies addressed the impact of invasion by nitrogen-fixing shrubs on soil quality and ...

Taxonomic revision of the genus Alternanthera (Amaranthaceae) in Italy [PDF]

open access: yes, 2015
A taxonomic revision of the genus Alternanthera (Amaranthaceae) in Italy is here presented. Field surveys were carried out during the period 2007–2013.

Adaptive Dynamics and Evolving Biodiversity [PDF]

open access: yes, 2004
Population viability is determined by the interplay of environmental influences and individual phenotypic traits that shape life histories and behavior.

Universal Power Laws Govern Intermittent Rarity in Communities of Interacting Species [PDF]

open access: yes, 1998
The temporal dynamics of many populations involve intermittent rarity, that is, the alternation, over variable periods of time, of phases of extremely low abundance, and short outbreaks.

Effects of temporal variability on rare plant persistence in annual [PDF]

open access: yes, 2004
Traditional conservation biology regards environmental fluctuations as detrimental to persistence, reducing long-term average growth rates and increasing the probability of extinction.

Positive diversity-invasibility relationship in species-rich semi-natural grassland at the neighbourhood scale [PDF]

open access: yes, 2017
Background and Aims Attempts to answer the old question of whether high diversity causes high invasion resistance have resulted in an invasion paradox: while large-scale studies often find a positive relationship between diversity and invasibility, small-

Nutrient enrichment, propagule pressure, and herbivory interactively influence the competitive ability of an invasive alien macrophyte Myriophyllum aquaticum

open access: yesFrontiers in Plant Science
IntroductionFreshwater ecosystems are susceptible to invasion by alien macrophytes due to their connectivity and various plant dispersal vectors. These ecosystems often experience anthropogenic nutrient enrichment, favouring invasive species that ...

A graphical theory of competition on spatial resource gradients

open access: yes, 2011
Resource competition is a fundamental interaction in natural communities.However little is known about competition in spatial environments where organisms are able to regulate resource distributions.
