Inbreeding vs outbreeding depression in a marine species with low dispersal potential

C Montecinos, C Álvarez, R Riera, A Brante - Marine Ecology, 2021 - Wiley Online Library
Inbreeding depression strongly affects the biological fitness of organisms throughout their
life cycle. These negative effects are more pronounced in species with low dispersal …

Lessons from the study of plant mating systems for exploring the causes and consequences of inbreeding in marine invertebrates

KC Olsen, WH Ryan, ET Kosman, JA Moscoso… - Marine Biology, 2021 - Springer
Many benthic marine invertebrates resemble plants in being modular and either sessile or
sedentary, and by relying on an external vector to disperse their gametes. These shared …

Mate choice in the face of both inbreeding and outbreeding depression in the intertidal copepod Tigriopus californicus

CA Palmer, S Edmands - Marine Biology, 2000 - Springer
In species vulnerable to both inbreeding and outbreeding depression, individuals might be
expected to choose mates at intermediate levels of genetic relatedness. Previous work on …

Self-fertilization and inbreeding depression in three ascidian species that differ in genetic dispersal potential

AL Phillippi, PO Yund - Marine Biology, 2017 - Springer
Although self-fertilization can mitigate the costs of sexual reproduction, many hermaphroditic
marine invertebrates avoid selfing, presumably because of inbreeding depression …

Brothers are better than nothing: first report of incestuous mating and inbreeding depression in a freshwater decapod crustacean

C Tropea, A Marciano, LSL Greco - Zoology, 2022 - Elsevier
This study aimed at evaluating the effect of one generation of full-sibling mating on traits
related to the fitness of the gregarious freshwater shrimp Neocaridina davidi, both under …

Effect of inbreeding on reproduction and juvenile performance in two marine gastropods with contrasting reproductive patterns

W Li, JA Pechenik - Marine Ecology Progress Series, 2007 - int-res.com
Many species avoid inbreeding through dispersal of individuals away from their natal groups
or sites. Benthic marine invertebrates with long free-living larval stages generally possess …
