Query: Estimating animal utilization distributions from multiple data types: a
  joint spatio-temporal point process framework   Models of the spatial distribution of animals provide useful tools to help
ecologists quantify species-environment relationships, and they are
increasingly being used to help determine the impacts of climate and habitat
changes on species. While high-quality survey-style data with known effort are
sometimes available, often researchers have multiple datasets of varying
quality and type. In particular, collections of sightings made by citizen
scientists are becoming increasingly common, with no information typically
provided on their observer effort. Many standard modelling approaches ignore
observer effort completely, which can severely bias estimates of an animal's
distribution. Combining sightings data from observers who followed different
protocols is challenging. Any differences in observer skill, spatial effort,
and the detectability of the animals across space all need to be accounted for.
To achieve this, we build upon the recent advancements made in integrative
species distribution models and present a novel marked spatio-temporal point
process framework for estimating the utilization distribution (UD) of the
individuals of a highly mobile species. We show that in certain settings, we
can also use the framework to combine the UDs from the sampled individuals to
estimate the species' distribution. We combine the empirical results from a
simulation study with the implications outlined in a causal directed acyclic
graph to identify the necessary assumptions required for our framework to
control for observer effort when it is unknown. We then apply our framework to
combine multiple datasets collected on the endangered Southern Resident Killer
Whales, to estimate their monthly effort-corrected space-use.
