Comparative Life Histories of Two Sympatric Ambystoma Species at a Breeding Pond in Massachusetts
—Spotted Salamanders (Ambystoma maculatum) and members of the Blue-Spotted Salamander complex (Ambystoma laterale-jeffersonianum complex) often share terrestrial and wetland habitats, allowing controlled comparison of their life-history strategies. We examined population sizes, sex ratios, breeding frequencies, recruitment rates, and age structures, in sympatric populations of Spotted Salamande...
متن کاملDemographic Approaches to Assessing Climate Change Impact: An Application to Pond-Breeding Frogs and Shifting Hydropatterns
Applications of conservation science to aquatic ecosystems have traditionally focused on water quality and quantity issues, the establishment of protected areas, the need for restoring impaired or reduced hydrological function (including fl ow regime), and the improvement of connectivity that has been damaged by freshwater infrastructure (Brönmark and Hansson 2002; Brinson and Malvarez 2002). A...
متن کاملSeasonal Spatial Patterns of Two Sympatric Frogs: California Red-legged Frog and American Bullfrog
—The introduced American Bullfrog (Lithobates catesbeianus) has been implicated in the decline of native amphibians. Bullfrogs have become widespread in California and are a threat to the native California Red-legged Frog (Rana draytonii). The two species are ecologically similar, and the bullfrog is a predator to the red-legged frog that may influence its habitat use patterns. We analyzed the ...
متن کاملBaseline Susceptibility of Different Geographical Strains of Anopheles stephensi (Diptera: Culicidae) to Temephos in Malarious Areas of Irana
BACKGROUND Malaria still remains a public health problem in Iran. There are different vector control interventions such as insecticide spraying. The present study was carried out to determine the susceptibility status of Anopheles stephensi larvae to temephos as a national plan for monitoring and mapping of insecticide resistance. METHODS Eight different localities in two main malarious provi...
متن کاملShadowed by scale: subtle behavioral niche partitioning in two sympatric, tropical breeding albatross species
BACKGROUND To meet the minimum energetic requirements needed to support parents and their provisioned offspring, the timing of breeding in birds typically coincides with periods of high food abundance. Seasonality and synchrony of the reproductive cycle is especially important for marine species that breed in high latitudes with seasonal booms in ocean productivity. Laysan and black-footed alba...
