Conservation Status of Two Endemic Rattlesnakes
in the Gulf of California
$1000
Of the 47 rattlesnake species described for the genus Crotalus, 42 (89%) are distributed in Mexico, from which 15 species (36%) are found in northwest Mexico. Six are endemic to Gulf of California islands, which have historically suffered from illegal collecting. The effect of illegal collecting on these insular rattlesnake populations is unknown, especially those species found on small islands. This is the case for Crotalus thalassoporus that inhabits Isla El Piojo, and C. polisi on Isla Cabeza de Caballo, both in Bahía de Los Ángeles. These two species (formerly C. mitchelli) were described in 2018. The islands El Piojo and Cabeza de Caballo have surface areas of 79 and 73 Ha, respectively. This study will collect baseline data for population size, prey diversity and abundance, and habitat condition for these new species. The project will also involve inhabitants of nearby Bahía de Los Angeles, to ensure their active participation in the rattlesnakes’ conservation and preventing illegal collecting.
The Fund will grant transportation costs between La Paz and Bahía de Los Ángeles, boat travel to the islands, and an education effort with Bahía de Los Ángeles residents.

Do Water Catchments in the Sonoran Desert
Create Population Sinks?
$469
Land and wildlife managers construct artificial water sources (catchments) in the Sonoran Desert to benefit large mammals, but they attract both target and non-target species including breeding aggregations of anurans. Unlike natural ephemeral water sources, many catchments provide year-round water, often including underground reservoirs. Previous research has shown that water quality in catchments suffer from accumulation of ammonia ions at levels toxic to anurans, as well as harboring the pathogenic chytrid fungus Batrachochytrium dendrobatidis, which has been implicated in a world-wide amphibian die-off. The objective of this study is to determine if Sonoran Desert catchments create population sinks (where mortality rate exceeds reproduction rate) for desert anurans. To accomplish this, water quality, breeding effort, breeding success, and survival of larvae and adult anurans will be compared between man-made catchments and natural water sources.
The Fund grant will be used to purchase iButton temperature loggers.

Thermal Acclimation Potential of Southwestern Salamanders:
An Extinction Risk Assessment Under Climate Change
$1000
An ecophysiological risk model on Ambystoma salamanders, based on water temperatures, larval periods, and temperatures during breeding, predicts a higher risk of extinction for paedomorphic salamander species relative to metamorphic species. This study investigates a factor not assessed in the previous risk model: thermal tolerance plasticity and the capacity for within-generation acclimation in the Ambystoma genus. Metamorphic taxa like Ambystoma experience greater climate variation throughout their life stages, possibly having evolved higher levels of thermal plasticity. The objective of this portion of the larger study is to investigate the thermal capacities of Ambystoma mavortium and A. stebbinsi, to (1) determine if microhabitats exceed dehydration and thermal limits of salamanders, (2) experimentally measure species’ current temperature performance and within-generation acclimation potential, and (3) develop extinction risk models. These data will help to produce an improved extinction risk model for Ambystoma and Dicamptodon salamanders, which will be incorporated into a phylogenetic analysis to assess species extinction risk across North America.
Location of proposed field work: Southern Arizona, and northern Sonora.
The Fund grant will pay for researchers’ travel costs and shipment of specimens back to Santa Cruz, CA.
