Functional Response and Intraspecific Competition in the Fall Armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae) [PDF]
Insects, 2020 Functional responses of the fall armyworm (FAW) larvae at each stage, and their intraspecific competition associated with cannibalism, provide insights into developing pest management strategies for the FAW.

Testing the relationship between intraspecific competition and individual specialization across both behavior and diet [PDF]
Ecology and Evolution, 2021 Individual specialization within populations is increasingly recognized as important in both ecology and evolution, but researchers working on intraspecific variation in behavior and diet infrequently interact.

Uric acid metabolism modulates diet-dependent responses to intraspecific competition in Drosophila larvae [PDF]
iScience, 2022 Summary: Intraspecific competition drives ecological specialization, and niche expansion. In holometabolous insects, larval intraspecific competition (“crowding”) has lasting fitness consequences for individuals and shapes adaptive responses.

Intraspecific competition for host resources in a parasite. [PDF]
Curr Biol, 2021 Intraspecific competition among parasites should, in theory, increase virulence, but we lack clear evidence of this from nature.1-3 Parasitic plants, which are sessile and acquire carbon-based resources through both autotrophy (photosynthesis) and heterotrophy (obtaining carbon from the host), provide a unique opportunity to experimentally study the ...

Neighborhood Diversity Promotes Tree Growth in a Secondary Forest: The Interplay of Intraspecific Competition, Interspecific Competition, and Spatial Scale [PDF]
PlantsUnderstanding the biodiversity–productivity relationship (BPR) is crucial for biodiversity conservation and ecosystem management. While it is known that diversity enhances forest productivity, the underlying mechanisms at the local neighborhood level ...

Intraspecific competition and individual behaviour but not urbanization affect the dietary patterns of a generalist avian predator [PDF]
Scientific Reports, 2023 Urbanization has reshaped ecosystems and changed natural processes, driving an intense transformation of biomes, biotic community composition and diversity. Despite the growing interest in studying urban ecology over the last decades, the consequences of

Effects of Temporal Heterogeneity of Water Supply and Spatial Heterogeneity of Soil Nutrients on the Growth and Intraspecific Competition of Bolboschoenus yagara Depend on Plant Density [PDF]
Frontiers in Plant Science, 2019 Clonal plants may face various types of resource heterogeneity in their natural habitats; as such, spatial or temporal resource heterogeneity can affect the growth of clonal plants.

Feeding strategies and intraspecific competition in German yellowjacket (Vespula germanica). [PDF]
PLoS ONE, 2018 The German yellowjacket (Vespula germanica) is an opportunist predator and a scavenger, whose eclectic diet also includes honey, brood, dead and live honey-bees.

Effects of intraspecific competition on the life cycle of the stonefly,
BMC Ecology, 2008 Background Considerable variation of life cycle duration in given insect species has been frequently recorded. Splitting of populations into cohorts with different life cycle lengths may occur, sometimes even between siblings from the same batch.

Robust coexistence in competitive ecological communities [PDF]
Nature CommunicationsDarwin already recognized that competition is fiercest among conspecifics, a principle that later made intraspecific competition central to ecological theory through concepts such as niche differentiation and limiting similarity.
