Correcting for unequal catchability in sex ratio and population size estimates
Wildlife populations often exhibit unequal catchability between subgroups such as males and females. This heterogeneity of capture probabilities can bias both population size and sex ratio estimates. Several authors have suggested that this problem can be overcome by treating males and females as separate populations and calculating a population estimate for each of them. However, this suggesti...
متن کاملInferring the depth distribution of catchability for pelagic fishes and correcting for variations in the depth of longline fishing gear
We introduce a new method that uses generalized linear mixed models to infer the depth distribution of pelagic fishes. It uses existing data from research surveys and observers on commercial vessels to estimate changes in catchability when longline fishing gear is lengthened to access deeper water. We infer the depth distribution of catchability for 37 fish species that are caught on pelagic lo...
متن کاملSpatial variation in hatch date distributions and origin of pelagic juvenile cod in Icelandic waters
Hatch date distributions, local spawning time and incubation temperatures at different spawning sites around Iceland were used to trace the most likely origin of 0-group cod. Length, age and hatch date frequency distributions were obtained from young larvae collected on the main spawning grounds off the south coast in 1995 and from pelagic 0-group cod captured in six nursery regions off the wes...
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولSpatial variation in abundance, size composition and viable egg production of spawning cod (Gadus morhua L.) in Icelandic waters
Changes in geographical location of spawning and/or in spatial abundance of spawners may influence offspring survival. In Iceland, the spatial dynamics of spawning cod (Gadus morhua L.) are complicated due to unequal distribution of size classes on the main spawning grounds. Information on abundance, age, and size distributions during peak spawning, potential fecundity, egg size, and estimated ...
