A multistate dynamic site occupancy model for spatially aggregated sessile communities
Keiichi Fukaya, J. Andrew Royle, Takehiro Okuda +2
Markov community models have been applied to sessile organisms because such models facilitate estimation of transition probabilities by tracking species occupancy at many fixed obs…
Exploitation dynamics of fish stocks
Hiro-Sato Niwa
I address the question of the fluctuations in fishery landings. Using the fishery statistics time-series collected by the Food and Agriculture Organization of the United Nations si…
Power-law scaling in dimension-to-biomass relationship of fish schools
Hiro-Sato Niwa
Motivated by the finding that there is some biological universality in the relationship between school geometry and school biomass of various pelagic fishes in various conditions,…
Space-irrelevant scaling law for fish school sizes
Hiro-Sato Niwa
Universal scaling in the power-law size distribution of pelagic fish schools is established. The power-law exponent of size distributions is extracted through the data collapse. Th…
Power-law versus exponential distributions of animal group sizes
Hiro-Sato Niwa
There has been some confusion concerning the animal group-size: an exponential distribution was deduced by maximizing the entropy; lognormal distributions were practically used; a…
