Facultative symbiont infections affect aphid reproduction.
PLoS ONE, 2011 Some bacterial symbionts alter their hosts reproduction through various mechanisms that enhance their transmission in the host population. In addition to its obligatory symbiont Buchnera aphidicola, the pea aphid Acyrthosiphon pisum harbors several ...

European Journal of Entomology, 2015 Facultative parthenogenesis is important for mayflies with short alate stages because females are able to reproduce without mating. We studied facultative parthenogenesis in Ephoron eophilum, a mayfly with an extremely short alate stage.

Is facultative sex the best of both worlds in the parasitoid wasp Lysiphlebus fabarum? [PDF]
Royal Society Open ScienceThe prevalence of sexual reproduction has long puzzled evolutionary biologists. This is because asexual parthenogenesis is a more efficient mode of reproduction, and all-else-being-equal, should predominate over sex.

Mechanism of facultative parthenogenesis in the ant Platythyrea punctata
Evolutionary Ecology, 2010 Thelytokous parthenogenesis, the production of diploid female offspring from unfertilized eggs, can be caused by several cytological mechanisms, which have a different impact on the genetic variation on the offspring. The ponerine ant Platythyrea punctata is widely distributed throughout the Caribbean Islands and Central America and exhibits ...

Geographical Divergence and Environmental Drivers of the Symbiotic Bacterial Community Structure in a <i>Koelreuteria</i>-Feeding Aphid Species Complex. [PDF]
Ecol EvolThis study investigates the symbiotic bacteria in the Periphyllus koelreuteriae aphid species complex, revealing an inverse relationship between the dominant symbionts Buchnera and Serratia. The relative abundance of these symbionts is strongly influenced by latitude and minimum winter temperature, suggesting that heat stress drives their ...

Sex at the margins: parthenogenesis vs. facultative and obligate sex in a Neotropical ant [PDF]
Journal of Evolutionary Biology, 2012 AbstractGeographic parthenogenesis is a distribution pattern, in which parthenogenetic populations tend to live in marginal habitats, at higher latitudes and altitudes and island‐like habitats compared with the sexual forms. The facultatively parthenogenetic ant Platythyrea punctata is thought to exhibit this general pattern throughout its wide range ...

Does ecology shape geographical parthenogenesis? Evidence from the facultatively parthenogenetic stick insect Megacrania batesii [PDF]
Ecology and EvolutionClosely related sexual and parthenogenetic species often show distinct distribution patterns, known as geographical parthenogenesis. Similar patterns, characterized by the existence of separate sexual and parthenogenetic populations across their natural ...

Distribution and Infestation of Gamasid Mite Androlaelaps fahrenholzi (Haemolaelaps glasgowi) on Small Mammals Across Five Provincial Regions of Southwest China. [PDF]
Vet Med SciAndrolaelaps fahrenhoizi, a potential vector of zoonotic diseases, is widely distributed in southwest China, predominantly infesting A. agrarius mice. The mite infestation is aggregated, and has environmental heterogeneity and age bias of hosts. Abundant A.

PLoS ONE, 2019 Reptiles show varying degrees of facultative parthenogenesis. Here we use genetic methods to determine that an isolated, captive female Asian water dragon produced at least nine offspring via parthenogenesis. We identified microsatellites for the species
