Eutrophication boosts the competitive advantage of invasive gibel carp over endangered crucian carp [PDF]

NeoBiota
Anthropogenic eutrophication poses a significant threat to freshwater environments globally. It also influences the population dynamics of invasive and native species, yet the cumulative effects of eutrophication and invasive species on native organisms ...

Effect of interspecific competition among whiteflies (Homoptera: Aleyrodidae) on crops and ornamental plants in Southwestern Nigeria

Journal of Applied Sciences and Environmental Management, 2021
Whiteflies that are pests of many crops and ornamental plants produce migratory forms during dense populations with different species sharing the same host plant. Fields surveys of these pests were conducted from 8 sampling sites within the five states (

Arboreal twig-nesting ants form dominance hierarchies over nesting resources. [PDF]

, 2019
Interspecific dominance hierarchies have been widely reported across animal systems. High-ranking species are expected to monopolize more resources than low-ranking species via resource monopolization. In some ant species, dominance hierarchies have been

Influence of temperature on intra- and interspecific resource utilization within a community of lepidopteran maize stemborers [PDF]

, 2016
Competition or facilitation characterises intra-and interspecific interactions within communities of species that utilize the same resources. Temperature is an important factor influencing those interactions and eventual outcomes. The noctuid stemborers,

Interspecific competition changes photosynthetic and oxidative stress response of barley and barnyard grass to elevated CO2 and temperature

Agricultural and Food Science, 2018
This work focuses on the investigation of competition interaction between C3 crop barley (Hordeum vulgare L.) and C4 weed barnyard grass (Echinochloa crus-galli L.) at 2 times higher than ambient [CO2] and +4 0C higher ambient temperature climate ...

Breakthrough of interspecific chimerism: blocking apoptosis

Cell Regeneration, 2021
On January 28 in Nature online, Zheng et al. (Nature, 2021 (Online ahead of print)) reported that they developed an ingenious method of interspecies PSC co-culture system in vitro which unfolded interspecific cell competition.

Who bullies whom at a garden feeder? Interspecific agonistic interactions of small passerines during a cold winter [PDF]

, 2015
Interspecific agonistic interactions are important selective factors for maintaining ecological niches of different species, but their outcome is difficult to predict a priori.

Physical habitat quality and interspecific competition interact to influence territory settlement and reproductive success in a cavity nesting bird

Frontiers in Ecology and Evolution, 2014
Determining how to best measure habitat quality is essential for many conservation plans and basic ecological questions. Territory quality is thought to be a product of physical habitat characteristics (i.e.

A comparative study of the function of heterospecific vocal mimicry in European passerines [PDF]

, 2007
Although heterospecific vocal imitation is well documented in passerines, the evolutionary correlates of this phenomenon are poorly known. Here, we studied interspecific variation in vocal mimicry in a comparative study of 241 European songbirds.
