SUMMARY Each spring, North American spotted salamander (Ambystoma maculatum) females each lay hundreds of eggs in shallow pools of water. Eggs are surrounded by jelly layers and are deposited as large gelatinous masses. Following deposition, masses are penetrated by a mutualistic green alga, Oophila amblystomatis, which enters individual egg capsules, proliferates and aggregates near the salamander embryo, providing oxygen that enhances development. We examined the effects of population density… 

Tables from this paper

Egg mass polymorphism in Ambystoma maculatum is not associated with larval performance or survival, or with cell density of the algal symbiont Oophila amblystomatis

TLDR
The data do not support the hypothesis that variation in predator density and light availability among microhabitats could maintain the two phenotypes within populations.

Heterotrophic Carbon Fixation in a Salamander-Alga Symbiosis

TLDR
The results confirm earlier studies suggesting a role of heterotrophic carbon fixation during vertebrate embryonic development and show that the considerable capacity of developing A. maculatum embryos for inorganic carbon fixation precludes the ability to distinguish any minor role of photosynthetically transferred carbon from algal symbionts to host salamanders using bicarbonate introduced to the egg system as a marker.

Phylogenetic Analysis of Algal Symbionts Associated with Four North American Amphibian Egg Masses

TLDR
Combined analysis shows that symbiotic algae found in egg masses of four North American amphibians are closely related to each other, and form a well-supported clade that also contains three strains of free-living chlamydomonads.

The Phenology of the Symbiotic Association between Ambystoma maculatum and Unicellular Algae (Oophila) Using Molecular Techniques

TLDR
Regression via linear mixed model estimation showed a positive relationship between the age of egg masses and the probability of algal DNA detection and a negative trend when comparing egg-mass age and qPCR cycle quantification value, which indicate an increase in both the probability that a given egg will contain algalDNA and the amount ofAlgal DNA an egg contains, if present, as age increases.

Dynamics of the growth, life history transformation and photosynthetic capacity of Oophila amblystomatis (Chlorophyceae), a green algal symbiont associated with embryos of the northeastern yellow spotted salamander Ambystoma maculatum (Amphibia)

TLDR
It is concluded that O. amblystomatis undergoes a life history transition in egg capsules and speculate that many of these symbionts become zygotes, rather than invading the embryo.

An advantage of clear over white egg mass morphs in metabolically demanding microhabitats suggests a role of symbiotic algae in the maintenance of a polymorphism in the spotted salamander (Ambystoma maculatum)

TLDR
When oxygen demand is high – such as in warm, shallow water – embryos from clear masses have higher survivorship than do those of white masses, supporting the hypothesis that the clear morph has a developmental advantage over the white morph that is mediated by algal symbionts.

Oophila is monophyletic within a three-taxon eukaryotic microbiome in egg masses of the salamander Ambystoma maculatum

TLDR
Assessment of diversity and relative abundance of algal and other unicellular eukaryotes in egg masses by subjecting DNA harvested from cells in egg capsules or water from breeding habitat to 18S amplicon sequencing provides a foundation for comparing microbial community structure within and among egg masses across the geographic range of the host.

Induction of Gametogenesis in the Cnidarian Endosymbiosis Model Aiptasia sp.

TLDR
It is found that simulating a lunar cycle with blue-wavelength light is necessary to promote abundant gamete production and synchronous release in well-fed animals and provides the requisite basis for further development of the Aiptasia model system.

Intracellular invasion of green algae in a salamander host

TLDR
The invasion of algae into salamander host tissues and cells represents a unique association between a vertebrate and a eukaryotic alga, with implications for research into cell–cell recognition, possible exchange of metabolites or DNA, and potential congruence between host and symbiont population structures.

Symbioses between salamander embryos and green algae

TLDR
Earlier research on this symbiosis between Ambystoma maculatum embryos and green algae is summarized and gaps in understanding are emphasized and various research avenues are suggested to address these unanswered questions.

Intermittent hypoxia in eggs of Ambystoma maculatum: embryonic development and egg capsule conductance

TLDR
Intermittent hypoxia caused comparable but less pronounced developmental delays than chronic Hypoxia and failed to elicit the measurable change in GO2 seen in ambystomatid salamander eggs exposed to chronic hypoxIA.

Observations on the Eggs of Ambystoma Maculatum with Especial Reference to the Green Algae Found Within the Egg Envelopes

TLDR
Algae probably "helps provide oxygen for the developing embryos in the presence of light and robs them of it in darkness" as well as on the possibility of a symbiotic relationship.

Annual Variation in Breeding Success of Two Syntopic Species of Ambystoma Salamanders

TLDR
Four years of monitoring the effects of temperature and egg mass distribution on breeding success in two populations of pond-breeding salamanders find the effect of oviposition site on egg mortality when eggs are attached to submerged substrates is reported.

TLDR
Analysis of a cylindrical egg mass model and measurement of oxygen gradients through egg masses indicated that diffusion alone was not adequate to deliver sufficient O2 to the innermost embryos at late developmental stages.

The work I wish to discuss is all concerned with the control of translocation of products of photosynthesis from the algae to the animals.

Ontogenetic influences on carbon flux in Aulactinia stelloides polyps (Anthozoa: Actiniaria) and their endosymbiotic algae

  • G. Smith
  • Environmental Science, Biology
  • 1986
TLDR
It is indicated that host developmental stage can influence zooxanthellae growth rates and consequently the rate of carbon flow within the association, which is dependent on the biosynthetic requirements of its developmental stage in addition to its nutritional status.
