1. The use of marine reserves as tools either for conservation or fisheries management requires rigorous empirical evidence for the recovery of exploited species within them. 2. The relative density and size structure of snapper Pagrus auratus (Sparidae), an intensively exploited reef fish species, were measured, using baited underwater video, inside and outside three northern New Zealand marin...

Link ratio techniques can be regarded as weighted regressions. We extend these regression models to handle different exposure bases and modeling of trends in the incremental data, and we develop a variety of diagnostic tools for testing the assumptions of these models. This “extended link ratio family” (ELRF) of regression models is used to test the assumptions made by standard link ratio techn...

This paper addresses the issue of biases in the loss reserving process, some of which may be intentional. Using an empirical analysis of data from 169 companies over a seventeen year period, it is observed that the level of loss reserves exhibits cyclical behaviour, is different for companies of different sizes and is different for reinsurers than for direct insurers. Furthermore, after these f...

Currently, the classification criterion of reserves were determined by the scope of the values of criteria such as geological attributes, reservoir phydical parameters and etc., which required all attribute values of one block were just right in the existing range of criteria, otherwise it would be difficult to divide the hard-to-recover reserves into different categories. To solve this problem...

Since seed reserves can influence seed germination, the quantitative and qualitative differences in seed reserves may relate to the germination characteristics of species. The purpose of our study was to evaluate the correlation between germination and seed reserves, as well as their mobilization during germination of six grassland species (Chloris virgata, Kochia scoparia, Lespedeza hedysaroid...

Regulatory capital guidelines allow for loan loss reserves to be added back as capital. The evidence in this paper suggests that the influence of loan loss reserves added back as regulatory capital (hereafter referred to as “add-backs”) on bank risk cannot be explained by either economic principles underlying the notion of capital, or accounting principles underlying the recording of reserves. ...

Establishment of marine protected areas, including fully protected marine reserves, is one of the few management tools available for local communities to combat the deleterious effect of large scale environmental impacts, including global climate change, on ocean ecosystems. Despite the common hope that reserves play this role, empirical evidence of the effectiveness of local protection against...

White-nose syndrome (WNS) is a new disease of bats that has devastated populations in eastern North America. Infection with the fungus, Geomyces destructans, is thought to increase the time bats spend out of torpor during hibernation, leading to starvation. Little is known about hibernation in healthy, free-ranging bats and more data are needed to help predict consequences of WNS. Trade-offs pr...
