Spatial mechanisms promoting plant coexistence. the role of dispersal and competition [PDF]

open access: yes, 2009
One of the great challenges in ecology is to explain how large numbers of plant species are able to coexist in natural communities. The role of spatial structure for maintaining plant coexistence has so far mainly been explored by theory.

Intraspecific interference retards growth and development of cane toad tadpoles, but those effects disappear by the time of metamorphosis

open access: yesRoyal Society Open Science, 2023
Competition among larval anurans can occur via interference as well as via a reduction in per-capita food supply. Previous research on intraspecific interference competition in cane toad (Rhinella marina) tadpoles found conflicting results, with one ...

Bipolar patterns of intraspecific competition in bryozoans [PDF]

open access: yes, 2005
Polar shores probably represent the most dynamic and extremely disturbed environments on the globe. Nevertheless intense battles amongst sessile organisms for space are commonplace on hard substrata, mainly between fast-growing pioneer species.

Small-scale spatial pattern and dynamics of experimental plant communities [PDF]

open access: yes, 2007
Plant-plant interference is inherently local and seed dispersal generally limited. Both processes generate spatial and genetic structure within plant populations and communities that need to be better understood in order to predict dynamic community ...

Mathematical Model of Iteroparous and Semelparous Species Interaction

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2022
A species can be categorized based on its reproductive strategy, including semelparous and iteroparous. Semelparous species is a species that reproduces only once in its lifetime shortly before dying, while iteroparous species is a species that ...

Genetic divergence and aggressiveness within a supercolony of the invasive ant Linepithema humile [PDF]

open access: yesNeoBiota, 2022
Biological invasions constitute an opportunity to study the evolutionary processes behind species’ adaptations. The invasive potential of some species, like the Argentine ant (Linepithema humile), has likely been increasing because they show low ...

Virus infection suppresses Nicotiana benthamiana adaptive phenotypic plasticity. [PDF]

open access: yesPLoS ONE, 2011
Competition and parasitism are two important selective forces that shape life-histories, migration rates and population dynamics. Recently, it has been shown in various pathosystems that parasites can modify intraspecific competition, thus generating an ...
