Natural selection on traits and trait plasticity in Arabidopsis thaliana varies across competitive environments

open access: yesScientific Reports, 2020
Interspecific competition reduces resource availability and can affect evolution. We quantified multivariate selection in the presence and absence of strong interspecific competition using a greenhouse experiment with 35 natural accessions of Arabidopsis

Female Fighting and Host Competition Among Four Sympatric Species of \u3ci\u3eMelittobia\u3c/i\u3e (Hymenoptera: Eulophidae) [PDF]

open access: yes, 2018
Melittobia is a genus of parasitic wasps well known for high levels of inbreeding and violent male combat. Casual observations of groups of sisters of M.

Detritus type alters the outcome of interspecific competition between Aedes aegypti and Aedes albopictus (Diptera : Culicidae) [PDF]

open access: yes, 2008
Many studies of interspecific competition between Aedes albopictus (Skuse) and Aedes aegypti (L.) (Diptera: Culicidae) larvae show that Ae. albopictus are superior resource competitors to Ae. aegypti.

Interspecific competition influences fitness benefits of assortative mating for territorial aggression in eastern bluebirds (Sialia sialis).

open access: yesPLoS ONE, 2014
Territorial aggression influences fitness and, in monogamous pairs, the behavior of both individuals could impact reproductive success. Moreover, territorial aggression is particularly important in the context of interspecific competition.

Nestedness in mutualistic networks [PDF]

open access: yes, 2013
James et al. (2012) presented simulations that apparently falsify the analytical result by Bastolla et al. (2009), who showed that nested mutualistic interactions decrease interspecific competition and increase biodiversity in model ecosystems.

INTERSPECIFIC COMPETITION, ISLAND BIOGEOGRAPHY AND NULL HYPOTHESES [PDF]

open access: yesEvolution, 1980
We conducted a field study of some of Darwin's Finches (Geospiza species) in order to assess the relative importance of interspecific competition and habitat features in determining the observed biogeographic, ecological and morphological characteristics of these species (Abbott et al., 1977). Strong et al. (1979) have criticized one of our methods and

A Local Replacement of \u3ci\u3eBombus Ternarius\u3c/i\u3e by \u3ci\u3eBombus Terricola\u3c/i\u3e in Northern Wisconsin (Hymenoptera: Apidae) [PDF]

open access: yes, 2017
During the last few years, the bumblebee Bombus ternarius Say has markedly decreased in numbers in Vilas County in northern Wisconsin while Bombus terricola Kirby has increased. The great ecological similarity of these species suggests that interspecific

Influence of Temperature on the Interaction for Resource Utilization between Fall Armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae), and a Community of Lepidopteran Maize Stemborers Larvae

open access: yesInsects, 2020
Intra- and interspecific interactions within communities of species that utilize the same resources are characterized by competition or facilitation.

Alien plant fitness is limited by functional trade‐offs rather than a long‐term increase in competitive effects of native communities

open access: yesEcology and Evolution, 2023
Alien plants experience novel abiotic conditions and interactions with native communities in the introduced area. Intra‐ and interspecific selection on functional traits in the new environment may lead to increased population growth with time since ...

Ecological Opportunity In Adaptive Radiation Of Galapagos Endemic Land Snails [PDF]

open access: yes, 2009
The classic evolutionary hypothesis of ecological opportunity proposes that both heterogeneity of resources and freedom from enemies promote phenotypic divergence as a response to increased niche availability.
