Dear all,

Next week Prof. Justin Kitzes 
<http://www.kitzeslab.org/people/>*//*(/University of Pittsburgh/, /PA/, 
/USA/) will give a talk as part of the iDiv Seminar Series:

*"**Predicting species loss in multi-patch networks: Two new approaches 
from spatial macroecology"*
*Wednesday, 22 May 2019*
12.30 pm
BBZ large lecture hall (BIO CITY)
*Abstract *Given the rapid pace of global biodiversity loss, a key 
challenge for ecology and conservation biology is to develop methods 
that can predict how global change drives changes in biodiversity. 
Pattern-based models based in spatial macroecology, including the 
species-area relationship and species distribution models, are widely 
used to relate species loss to changes in available habitat, 
particularly when detailed data on species’ life history traits are not 
available. A key shortcoming of these approaches, however, is that they 
are often designed to make predictions for a single location on a 
landscape, and do not predict total richness or diversity across a 
network of patches. Here, I describe two new approaches that 
specifically address this multi-patch question. First, I describe the 
results of a nearly decade-long quest to determine whether and how 
patterns of spatial scaling (how diversity in a single plot changes with 
the area of that plot - a single patch metric) are fundamentally related 
to patterns of spatial turnover (how shared diversity between two plots 
changes with the distance between those plots - a two-patch metric). We 
have determined that for individual species, these two patterns are 
quantitatively and exactly linked, such that either pattern can be 
derived from the other. This relationship provides insight into the 
relationship between alpha and beta diversity and points the way towards 
deriving multi-patch variations of species-area relationships that can 
predict changes in diversity in fragmented habitats. Second, I describe 
new ideas for a very general, constraint-based approach to species 
distribution modeling that is designed to predict the occurrence of a 
species simultaneously across many grid cells. This method is based on a 
frequentist interpretation of Jaynes' Maximum Entropy principle and can 
be used to predict the conditional occurrence of a species in a cell 
given its known presence in other cells, or the joint occurrence of a 
species across many cells simultaneously. We are currently exploring 
computational methods for the calculation of these probabilities in 
realistically large landscapes.

*Justin's research* combines methods from spatial ecology, data science, 
and conservation biology in order to better measure, understand, and 
predict biodiversity loss. His specific areas of interest include 
macroecology, the species-area relationship, community turnover in space 
and time, acoustic recording technology, bird and bat call 
classification, software development, reproducible research, and 
sustainability accounting.

*Meeting Justin?***Justin will be at iDiv on Wednesday, leaving at 
15:00. Tuesday afternoon is also possible. If you'd like to meet him, 
let me know and I will arrange a meeting for you.
