Because species, populations and ecological processes occur at a range of spatial scales, it is vital to incorporate a multi-scale approach into an assessment of ecological condition and conservation measures (Poiani et al. 2000). This is consistent with the National Forest Management Act which requires the maintenance of viable and well distributed populations throughout all national forest la...

Most hatchery programs for anadromous salmonids have been initiated to increase the numbers of fish for harvest, to mitigate for habitat losses, or to increase abundance in populations at low abundance. However, the manner in which these programs are implemented can have significant impacts on the evolutionary trajectory and long-term viability of populations. In this paper, we review the poten...

Mathematical modelling of dynamical systems often yields partial differential equations (PDEs) in time and space, which represent a conservation law possibly including a source term. Uncertainties in physical parameters can be described by random variables. To resolve the stochastic model, the Galerkin technique of the generalised polynomial chaos results in a larger coupled system of PDEs. We ...

Conservation of genetic resources is connected with numerous problems which solution is crucial for the success of the entire program. At present the only effective method of long-term conservation of genetic material is its deep freezing in liquid nitrogen at -196°C. Some positive results were also obtained with the use of liquid oxygen which allows the use of lower temperatures. Cryo-conserva...

Across large parts of the world, wildlife has to coexist with human activity in highly modified and fragmented landscapes. Combining concepts from population viability analysis and spatial reserve design, this study develops efficient quantitative methods for identifying conservation core areas at large, even national or continental scales. The proposed methods emphasize long-term population pe...

Electronically signed documents can lose value of evidence because the security of cryptographic algorithms decreases in the course of time. In this paper we describe legal, technical and user-oriented requirements for long-term conservation of provability of electronically signed documents, which were systematically examined in the project “ArchiSig Conclusive and secure long term archiving of...

Studies of conservation in small scale societies typically portray indigenous peoples as either sustainably managing resources, or forsaking long-term sustainability for short-term gains. To explain this variability, we propose an alternative framework derived from a co-evolutionary perspective. In environments with long histories of consistent interaction, we suggest that local species will fr...

Long-term research should play a crucial role in addressing grand challenges in environmental stewardship. We examine the efforts of five Long Term Ecological Research Network sites to enhance policy, management, and conservation decisions for forest ecosystems. In these case studies, we explore the approaches used to inform policy on atmospheric deposition, public land management, land conserv...
