Computation And Interpretation Of Biological Statistics Of Fish Populations
TLDR
This computation and interpretation of biological statistics of fish populations, but end up in harmful downloads so that people cope with some infectious bugs inside their laptop.Abstract:
Thank you for reading computation and interpretation of biological statistics of fish populations. As you may know, people have search numerous times for their favorite books like this computation and interpretation of biological statistics of fish populations, but end up in harmful downloads. Rather than enjoying a good book with a cup of coffee in the afternoon, instead they cope with some infectious bugs inside their laptop.read more

Climate-driven declines in arthropod abundance restructure a rainforest food web.
Bradford C. Lister,Andrés García +1 more
TL;DR: While El Niño/Southern Oscillation influences the abundance of forest arthropods, climate warming is the major driver of reductions in arthropod abundance, indirectly precipitating a bottom-up trophic cascade and consequent collapse of the forest food web.
Journal ArticleDOI
Estimating Fisheries Reference Points from Catch and Resilience
TL;DR: In this article, a Monte Carlo method (CMSY) was used for estimating fisheries reference points from catch, resilience and qualitative stock status information on data-limited stocks, which gave good predictions of the maximum intrinsic rate of population increase r, unexploited stock size k and maximum sustainable yield MSY when validated against simulated data with known parameter values.
Journal ArticleDOI
Direct and indirect responses of a freshwater food web to a potent synthetic oestrogen
Karen A. Kidd,Michael J. Paterson,Michael D. Rennie,Cheryl L. Podemski,Dave L. Findlay,Paul J. Blanchfield,Karsten Liber +6 more
TL;DR: The results demonstrate that small-scale studies focusing solely on direct effects are likely to underestimate the true environmental impacts of oestrogens in municipal wastewaters and provide further evidence of the value of whole-ecosystem experiments for understanding indirect effects of EDCs and other aquatic stressors.
Book ChapterDOI
Environmental Effects on Cephalopod Population Dynamics: Implications for Management of Fisheries
Paul G. Rodhouse,Graham J. Pierce,Owen C. Nichols,Warwick H. H. Sauer,Alexander I. Arkhipkin,Vladimir Laptikhovsky,Marek R. Lipinski,Jorge E. Ramos,Michaël Gras,Hideaki Kidokoro,Kazuhiro Sadayasu,João Pereira,Evgenia Lefkaditou,Cristina Pita,Maria A. Gasalla,Manuel Haimovici,Mitsuo Sakai,Nicola Downey +17 more
TL;DR: Assessment in many fisheries is complicated because cephalopods are ecological opportunists and stocks appear to have benefited from the reduction of key predator by overexploitation, so there is a particular need for a precautionary approach in these cases.
Oil Platforms off California are among the Most Productive Marine Fish Habitats Globally
Daniel J. Pondella,Jeremy T. Claisse,Milton S. Love,Laurel A. Zahn,Jonathan P. Williams,Chelsea M. Williams,Ann Scarborough Bull +6 more
TL;DR: The authors found that fish communities living on the complex hardscape habitat created throughout the water column by the structure of oil and gas platforms off California have the highest secondary production per unit area of seafloor of any marine ecosystem for which similar estimates exist.
