Artificial propagation is commonly used to reduce extinction risk for native, imperiled fish species. Thus, identifying stocking strategies that most effectively augment adult abundance a critical aspect of successful adaptive management. The threatened June sucker ( Chasmistes liorus) , endemic Utah Lake, UT, USA, experienced major declines in following extensive ecosystem degredation. Over 80...

Abundance estimates are essential for fisheries management, but estimating the abundance of open populations with low recapture rates has historically been unreliable. However, by using mark-recapture data modulated survivability parameters obtained from analysis acoustic telemetry data, more accurate can be made species that exhibit these characteristics. One such is Atlantic sturgeon, which w...

Population estimates for female or immature male sperm whales (Physeter macrocephalus) in a region within the Azores archipelago are given, based on photo-identification studies with mark-recapture analysis. The study area encompassed Central Group of islands and island São Miguel. Data indicate that recapture rate animals likely to be females differs from other animals, this heterogeneity is i...

Determining population trends is critical for evaluating management actions and prioritizing species protections. In this study, we used empirical data to produce an estimate of the trend sub-adult adult white sharks in central California. We unique dorsal fin morphology build a mark-recapture set modified Jolly-Seber model (POPAN formulation) annual abundance then investigate growth rates usin...

Juvenile survival and recruitment can be more sensitive to environmental, ecological and anthropogenic factors than adult survival, influencing population-level processes like recruitment and growth rate in long-lived, iteroparous species such as southern right whales. Conventionally, Southern right whales are individually identified using callosity patterns, which do not stabilise until 6-12 m...

“When you are high, it is tremendous. Shyness goes, the right words and gestures are suddenly there, the power to seduce and captivate others a felt certainty. Feelings of ease, intensity, power, well-being, financial omnipotence and euphoria now pervade one’s marrow. But somehow, this changes. The fast ideas are far too fast and there are far too many, overwhelming confusion replaced by fear a...

Maxillectomy often leads to oralnasal or excessive oral-pharyngeal communication. The remaining teeth may need further preparation for various reasons, including crown or fixed dental prosthesis restoration. High-volume water is used in conjunction with highspeed tooth preparation to avoid the excessive heat generation that could endanger the health of the pulp. The water aerosol generated by t...

The photooxidation of thebaine (3) with a sun lamp affords two main products: hydrodibenzofuran 10 (major) and benzofuran 11 (minor). The latter compound becomes predominant if a Hg lamp is used instead of a sun lamp. The formation of 10 proceeds via an endoperoxide intermediate that undergoes oxidation at the nitrogen atom. Protection of the nitrogen either by protonation or quaternization pre...

Mark-recapture models are extensively used in quantitative population ecology, providing estimates of population vital rates, such as survival, that are difficult to obtain using other methods. Vital rates are commonly modeled as functions of explanatory covariates, adding considerable flexibility to mark-recapture models, but also increasing the subjectivity and complexity of the modeling proc...
