City of Seattle, Seattle Public Utilities, Amphibian Egg Mass Counts 2002 - Current, Cedar River Municipal Watershed, King County, WA
This data package contains survey data beginning in 2002 for amphibian egg masses in five small kettle lakes (known as "14 Lakes") in the Cedar River Municipal Watershed, located in King County, Washington, USA. These surveys are conducted annually and are intended to be continued. The lakes range in size from 0.8 to 4.3 acres, have no perennial inlet or outlet, and were formed through glacial outwash deposits. The lakes are located at an elevation of 800 feet and are well suited for pond breeding amphibians because the lakes have no fish. Surveys were conducted annually, typically during the last week of March or first week of April, to coincide with amphibian breeding seasons. Surveyors walked, waded, or paddled the perimeter of each of the lakes during a survey, and tallied the number and type of egg masses that were encountered. Red legged frogs (Rana aurora) were of specific interest for the surveys, though egg masses of other species were noted during some survey years. The lakes represent the largest known breeding concentration of red legged frogs in the municipal watershed. The water depth of the lakes fluctuates year-to-year, which affected the feasibility of surveys. Lower water levels correspond to easier survey conditions: steep slopes and thick vegetation make surveying challenging when the water is high. Surveys were periodically cancelled during years where high water made surveying difficult or during staffing shortages. Counts of red legged frog egg masses across all lakes ranged between 24 and 1778 in a given year.
Butterfly heavy metal content, wing size, egg count, and brain mass in the Minneapolis-St. Paul (MSP) Metropolitan Area
We collected 26 common species of butterflies across a gradient of lead pollution in the Twin Cities metropolitan area (Minneapolis and St. Paul, MN, USA). We measured their thorax lead concentrations and their body condition including wing area, number of eggs, and brain mass. We also quantified lead in the soil, host plant leaves, and air (through lichen bio-monitors) at sites where the butterflies were collected.

Data from: Egg mass polymorphism in Ambystoma maculatum is not associated with larval performance or survival, or with cell density of the algal symbiont Oophila amblystomatis
<p>These data are from a 2018 study of larval morphology, performance, and survival in the spotted salamander (<em>Ambystoma maculatum</em>). We examined larvae of two egg mass color morphs: clear and white. We also quantified the density of algal (<em>Oophila amblystomatis</em>) cells on the egg capsules of embryos. The data correspond to our publication in <em>Evolutionary Ecology</em>.</p>

Data from: Mortality and morphology in egg masses of unisexual and Jefferson Salamanders
<p><span>Unisexual <i>Ambystoma </i>salamander egg masses have often been observed to exhibit very high rates of embryo mortality. The ecological consequences and underlying mechanisms are of great concern to researchers and managers studying these and other members of the species complex, all of which are listed as rare species throughout much of their range. Substantial embryo mortality is commonly used by field ecologists as an indicator that unisexual salamanders are present in a pond; egg masses of unisexual salamanders appear otherwise very similar to those of <i>A. jeffersonianum</i> (Jefferson Salamander). Early researchers suggested that elevated mortality among unisexual salamanders was due to lack of fertilization caused by sperm limitation. However, recent work has suggested that embryo failure is due to genetic errors particular to the unisexual salamander lineage. Our goals in this study were to (1) identify when during development embryonic mortality occurs in unisexual salamanders, and (2) to develop a morphological metric to distinguish egg masses of unisexual and Jefferson salamanders. Collecting from sites across western Massachusetts, we reared 356 eggs from 11 egg masses of known species identity in the laboratory, examined field photographs of 96 egg masses of known species identity (based on mitochondrial sequencing and 6 microsatellite alleles), and examined 757 field photographs of egg masses of unknown species identity. We developed a simple, scale-independent metric to distinguish Jefferson Salamander egg masses from those of co-occurring unisexual salamanders. Among developing embryos beyond the earliest stages, we found no difference in mortality rates between unisexual salamanders and Jefferson Salamanders. However, we observed a large pulse of embryo mortality in the earliest stages of development, followed by a trickle of additional mortality at later stages. Our results suggest that the primary cause of embryo mortality in Massachusetts populations of unisexual salamanders involves failure of embryos to initiate development.</span></p>
