Interspecific resource competition effects on fisheries revenue. [PDF]

open access: yesPLoS ONE, 2012
In many fisheries multiple species are simultaneously caught while stock assessments and fishing quota are defined at species level. Yet species caught together often share habitat and resources, resulting in interspecific resource competition.

The importance of aboveground and belowground interspecific interactions in determining crop growth and advantages of peanut/maize intercropping

open access: yesCrop Journal, 2021
Intercropping of maize (Zea mays L.) and peanut (Arachis hypogaea L.) often results in greater yields than the respective sole crops. However, there is limited knowledge of aboveground and belowground interspecific interactions between maize and peanut ...

Effects of Intra- and Interspecific Plant Density on Rhizosphere Bacterial Communities [PDF]

open access: yesFrontiers in Microbiology, 2020
There have been very few studies on the effects of plant competition on the rhizosphere bacterial community. To investigate the impacts of intra- and interspecific plant competition, we analyzed the responses of rhizosphere bacterial communities to plant

Intraspecific Versus Interspecific Scaling of Metabolic Rate: Tests of the Metabolic Theory of Ecology Across Biological Hierarchies [PDF]

open access: yesBiology
The Metabolic Theory of Ecology (MTE) proposes universal constants for the scaling of metabolic rate (BMR) with body mass and temperature. However, the validity of these constants across different biological hierarchies, specifically within versus ...

Roles of clonal parental effects in regulating interspecific competition between two floating plants

open access: yesFrontiers in Plant Science, 2022
Parental effects can influence offspring fitness, which may further impact interspecific competition. However, few studies have tested the role of clonal parental effects in regulating interspecific interactions and examined the underlying mechanisms. We

Direct and indirect effects of climate change on a prairie plant community. [PDF]

open access: yesPLoS ONE, 2009
Climate change directly affects species by altering their physical environment and indirectly affects species by altering interspecific interactions such as predation and competition.

What Drives Life-History Variation in the Livebearing Fish Poeciliopsis prolifica? An Assessment of Multiple Putative Selective Agents

open access: yesFrontiers in Ecology and Evolution, 2021
Life-history traits are directly linked to fitness, and therefore, can be highly adaptive. Livebearers have been used as models for understanding the evolution of life histories due to their wide diversity in these traits.

Spatial co-occurrence patterns of sympatric large carnivores in a multi-use African system.

open access: yesPLoS ONE, 2023
Interspecific interactions can be a key driver of habitat use, and must be accounted for in conservation planning. However, spatial partitioning between African carnivores, and how this varies with scale, remains poorly understood.

Habitat isolation reduces intra- and interspecific biodiversity and stability

open access: yesRoyal Society Open Science, 2022
Fragmentation is predicted to reduce biodiversity and stability by increasing habitat isolation and impeding dispersal among patches. These effects may manifest at both the interspecific and intraspecific levels, yet few studies have simultaneously ...

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.
