Spatial heterogeneity in light supply affects intraspecific competition of a stoloniferous clonal plant. [PDF]

open access: yesPLoS ONE, 2012
Spatial heterogeneity in light supply is common in nature. Many studies have examined the effects of heterogeneous light supply on growth, morphology, physiology and biomass allocation of clonal plants, but few have tested those effects on intraspecific ...

Warming mediates intraspecific multiple predator effects from an invasive crustacean [PDF]

open access: yes, 2021
Invasive alien species impacts might be mediated by environmental factors such as climatic warming. For invasive predators, multiple predator interactions could also exacerbate or dampen ecological impacts.

A direct comparison of the effects and mechanisms between species richness and genotype richness in a dominant species on multiple ecosystem functions

open access: yesEcology and Evolution, 2021
Both species (interspecific) richness and genotype (intraspecific) richness of dominant species have significant effects on ecosystem functioning directly or indirectly by regulating plant community functional structure.

The relative effects of interspecific and intraspecific diversity on microplastic trapping in coastal biogenic habitats [PDF]

open access: yes, 2022
Our understanding of how anthropogenic stressors such as climate change and plastic pollution interact with biodiver-sity is being widened to include diversity below the species level, i.e., intraspecific variation.

Intraspecific density effect on growth of Marphysa “sp.” Juveniles

open access: yesScientia Marina, 2021
There is growing demand for the territorial tube-building genus Marphysa (Eunicidae: Polychaete), commonly known in Portugal as “goose”, for use as fishing bait, and it is being harvested all around the world for that purpose. Effects of intraspecific density on juvenile growth were studied over a four-month period in laboratory facilities.

Persistence of deterrent larval tracks in Coccinella septempunctata, Cycloneda limbifer and Semiadalia undecimnotata (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2002
The persistence of oviposition-deterring effects of coccinellid and chrysopid larval tracks on females of three aphidophagous coccinellid species was compared.

Oviposition-deterring effects of conspecific and heterospecific larval tracks on Cheilomenes sexmaculata (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2006
The oviposition deterring effects of fresh larval tracks of Cheilomenes sexmaculata (F.), Ceratomegilla undecimnotata (Schneider), Cycloneda limbifer Casey, and Harmonia dimidiata (F.) on C. sexmaculata females were compared in standard laboratory choice

Cooperation and Lateral Forces: Moving Beyond Bottom-Up and Top-Down Drivers of Animal Population Dynamics

open access: yesFrontiers in Psychology, 2022
Biologists have long known that animal population dynamics are regulated by a combination of bottom-up (resource availability) and top-down forces (predation).

Nonlinear Effects of Intraspecific Competition Alter Landscape-Wide Scaling Up of Ecosystem Function

open access: yesAmerican Naturalist, 2020
A major focus of ecology is to understand and predict ecosystem function across scales. Many ecosystem functions are measured only at local scales, while their effects occur at a landscape level.

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 ...
