Predatory interaction of marine mammals with longline fisheries is observed globally, leading to partial or complete loss of the catch and in some parts of the world to considerable financial loss. Depredation can also create additional unrecorded fishing mortality of a stock and has the potential to introduce bias to stock assessments. Here we aim to characterise depredation in the Patagonian ...

Genetic markers are increasingly used for ascertaining the population of origin of individuals or mixtures of individuals in Pacific salmon mixed stock fisheries. Multilocus genotype data from single nucleotide polymorphisms (SNPs) are especially useful for admixture analyses. SNPs can be discovered in non-model organisms with relative ease and may be characterized in coding regions of the geno...

Schizothorax curvifrons is a morphometrically and meristically most variable and economically valuable promising fish food from Kashmir Valley. Since there is a lack of information on stock structure of wild populations on this species, this study was aimed to investigate the intraspecific variation of this important snowtrout. For this, two rivers and one lake in Kashmir Himalaya were sampled ...

Savannas and adjacent vegetation types like gallery forests are highly valuable ecosystems contributing to several ecosystem services including carbon budgeting. Financial mechanisms such as REDD+ (Reduced Emissions from Deforestation and Forest Degradation) can provide an opportunity for developing countries to alleviate poverty through conservation of its forestry resources. However, for avai...

Non-linear external habit persistence models, which feature prominently in the recent “equity premium” asset pricing and macroeconomics literature, generate counterfactual predictions in the cross-section of stock returns. In particular, we show that in the absence of crosssectional heterogeneity in firms’ cash-flow risk, these models produce a “growth premium,” that is, stocks with high price-...

We show that a simple structural model of credit risk is able to generate credit yield spreads for the low-rated bonds close to the historical spreads once the recent trends in the stock volatility are taken into account. We study the idiosyncratic and market volatility of stock returns in the cross-section of credit ratings. We find that the increase in the level of the firm-specific volatilit...

China’s rapid urbanization has led to increasing steel consumption for buildings and civil engineering infrastructure. The in-use steel stock in the same is considered to be closely related to social welfare and urban metabolism. Traditional approaches for determining the in-use steel stock are labor-intensive and time-consuming processes and always hindered by the availability of statistical d...
