Intracapsular algae provide fixed carbon to developing embryos of the salamander Ambystoma maculatum.
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 emb...
متن کاملObservations on the Eggs of Ambystoma Maculatum with Especial Reference to the Green Algae
Those who have observed large numbers of eggs of the spotted salamander (Amnbystorna maculatum) have undoubtedly seen many masses colored a delicate or even a vivid green. The color of these egg masses is due to unicellular green algae which thrive in the egg envelopes, eventually giving to the jelly a green appearance. Often the algal growth, especially within the innermost jelly envelope, is ...
متن کاملThreat of predation alters aggressive interactions among spotted salamander (Ambystoma maculatum) larvae
Intraspecific aggression represents a major source of mortality for many animals and is often experienced alongside the threat of predation. The presence of predators can strongly influence ecological systems both directly by consuming prey and indirectly by altering prey behavior or habitat use. As such, the threat of attack by higher level predators may strongly influence agonistic interactio...
متن کاملAnalysis of Spotted Salamander (Ambystoma maculatum) Growth Rates Based on Long-Bone Growth Rings
—Amphibians experience indeterminate growth, but although factors affecting larval growth are relatively well studied, less is known about correlates of postmetamorphic growth. We measured areas between lines of arrested growth (inter-LAG) to determine yearly growth rates to test whether the postmetamorphic growth of 32 Spotted Salamanders (Ambystoma maculatum) was related to age, sex, or year ...
متن کاملFine-scale spatial genetic structure and dispersal among spotted salamander (Ambystoma maculatum) breeding populations.
We examined fine-scale genetic variation among breeding aggregations of the spotted salamander (Ambystoma maculatum) to quantify dispersal, interpopulation connectivity and population genetic structure. Spotted salamanders rely on temporary ponds or wetlands for aggregate breeding. Adequate breeding sites are relatively isolated from one another and field studies suggest considerable adult site...
