Does past evolutionary history under different mating regimes influence the demographic dynamics of interspecific competition?

open access: yesEcology and Evolution, 2019
Interspecific interactions are contingent upon organism phenotypes, and thus phenotypic evolution can modify interspecific interactions and affect ecological dynamics.

Endothelial p130cas confers resistance to anti-angiogenesis therapy

open access: yesCell Reports, 2022
Summary: Anti-angiogenic therapies, such as anti-VEGF antibodies (AVAs), have shown promise in clinical settings. However, adaptive resistance to such therapies occurs frequently.

Sphingosine Phosphate Lyase Expression Is Essential for Normal Development in Caenorhabditis elegans [PDF]

open access: yes, 2003
Sphingolipids are ubiquitous membrane constituents whose metabolites function as signaling molecules in eukaryotic cells. Sphingosine 1-phosphate, a key sphingolipid second messenger, regulates proliferation, motility, invasiveness, and programmed cell ...

Interspecific Courtship Between Two Endemic Fireflies

open access: yesDiversity
Reproductive interactions between species could have negative effects on the fitness of the species involved, which can have important ecological and evolutionary consequences, such as population declines (including local extinction) or character ...

Direct and indirect effect of cannibalism and intraguild predation in the two sibling Harmonia ladybird beetles

open access: yesEcology and Evolution, 2020
In this study, we focused on the direct (i.e., predation) and indirect (i.e., potential threat from coexisting with a larger individual) effects of cannibalism and intraguild predation (IGP) during larval stages of two sibling ladybird beetles.

Asymmetric reproductive interference between specialist and generalist predatory ladybirds [PDF]

open access: yesJournal of Animal Ecology, 2012
Summary1. Closely related species often differ greatly in the quality and breadth of resources exploited, but the actual mechanisms causing these differences are poorly understood. Because in the laboratory specialized species often survive and perform as well or better on host species that are never utilized in nature, negative ecological interactions

Morphological variation and reproductive isolation in the Hetaerina americana species complex

open access: yesScientific Reports, 2022
Incomplete premating barriers in closely related species may result in reproductive interference. This process has different fitness consequences and can lead to three scenarios: niche segregation, sexual exclusion, or reproductive character displacement.

FABP4 as a key determinant of metastatic potential of ovarian cancer

open access: yesNature Communications, 2018
In ovarian cancer, metastatic phenotype may impact surgical outcomes. Here, the authors show miR-409-3p regulates FABP4 which can increase metastatic potential of ovarian cancer, and treatment with DOPC nanoliposomes containing either miR-409--3p mimic ...

Infanticide and infant defence by males--modelling the conditions in primate multi-male groups [PDF]

open access: yes, 2004
Infanticide by primate males was considered rare if groups contain more than one adult male because, owing to lower paternity certainty, a male should be less likely to benefit from infanticide.
