Guppies inhabit streams in Trinidad and habitats can be categorised into high and low predation areas. Experimental transplants of guppies from high to low predation streams were performed in 2008 and 2009. All introduced fish were adult and individually marked at introduction and mark-recapture data is collected each month, along with individual level data is also collected as well as location in the steam data.\u00a0She<\/span> discussed the challenges of analysing these data and presented modelling approaches for answering key ecological questions.<\/p>\n Natoya<\/strong> gave a talk on Abundance estimation using integrated modelling of unmarked animal data from camera traps<\/strong>.<\/p>\n She talked about\u00a0using camera trap data to estimate animal density when the animals do not have unique markings, using the random encounter model.<\/p>\n Byron<\/strong> gave a talk on Modelling\u00a0meetkats<\/strong><\/p>\n He presented results from a multi-state analysis of Meerkats. Interesting features include the facts that the animals live in social groups, and are cooperative breeders: usually only the dominant female in each group reproduces, and other females assist the dominant female. There is a remarkable discrepancy in lifespans, with the dominant females greatly outliving other females.<\/p>\n Anita<\/strong> gave a talk on Detecting heterogeneity in capture-recapture models: diagnostic goodness-of-fit tests<\/strong><\/p>\n Capture-recapture models have increased in complexity in order to be more biologically realistic. It is possible to fit many models to the same dataset, and the best model is generally chosen using information criteria, which will select the least worst model among the subset of tested models. Hence, it is important to check that candidate models fit the data adequately. She\u00a0presented work investigating\u00a0the use of diagnostic goodness-of-fit tests to find out whether this type of heterogeneity can be detected and specifically identified: for instance, does heterogeneity in capture affect the tests differently from a combination of trap-dependence and transience?\u00a0She derived a specific diagnostic test for heterogeneity in capture and use simulation to assess its performance.<\/p>\n![\"NatoyaNCSE\"](\"http:\/\/blogs.kent.ac.uk\/seak\/files\/2015\/08\/NatoyaNCSE.jpg\")
