Efficient use of harvest data: a size‐class‐structured integrated population model for exploited populations

چکیده
Many animal populations are subject to hunting or fishing in the wild. Detailed knowledge of demographic parameters (e.g. survival, reproduction) and temporal dynamics such is crucial for sustainable management. Despite their relevance management decisions, structure size exploited often not known, data limited. Recently, joint analysis different types data, as population counts, reproductive capture–mark–recapture within integrated models (IPMs) has gained much popularity it may allow estimating structure, well key rates, while fully accounting uncertainty. IPMs built so far have typically been age-structured models. However, age harvested individuals usually difficult and/or costly assess therefore available. Here, we introduce an IPM structured by body classes, which allows making efficient use commonly available accurate information on missing. The model jointly analyzes size-at-harvest capture–mark–recapture–recovery reproduction from necropsies, illustrate its applicability a case study involving heavily hunted wild boar. This species increased abundance over last decades despite intense harvest, provides insights into roles natural mortality, growth, maturation schedules output compensating loss hunting. Early high contributed boar persistence strong pressure. We thus demonstrate potential size-class-structured tools investigate with limited age, highlight both this framework other follow-up analyses highly relevant

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
