Journal ArticleDOI
The importance of correcting for sampling bias in MaxEnt species distribution models
Stephanie Kramer-Schadt,Jürgen Niedballa,John D. Pilgrim,Boris Schröder,Boris Schröder,Jana Lindenborn,Vanessa Reinfelder,Milena Stillfried,Ilja Heckmann,Anne K. Scharf,Dave M. Augeri,Susan M. Cheyne,Andrew J. Hearn,Joanna Ross,David W. Macdonald,John Mathai,James A. Eaton,Andrew J. Marshall,Gono Semiadi,Rustam Rustam,Henry Bernard,Raymond Alfred,Hiromitsu Samejima,J. W. Duckworth,Christine Breitenmoser-Wuersten,Jerrold L. Belant,Heribert Hofer,Andreas Wilting +27 more
TL;DR: It is concluded that a substantial improvement in the quality of model predictions can be achieved if uneven sampling effort is taken into account, thereby improving the efficacy of species conservation planning.
Journal ArticleDOI
MHC-dependent mate choice is linked to a trace-amine-associated receptor gene in a mammal
Pablo Sandro Carvalho Santos,Pablo Sandro Carvalho Santos,Alexandre Courtiol,Andrew J. Heidel,Oliver P. Höner,Ilja Heckmann,Martina Nagy,Frieder Mayer,Matthias Platzer,Christian C. Voigt,Simone Sommer,Simone Sommer +11 more
TL;DR: The results suggest that TAARs and olfactory cues may be key mediators in mammalian MHC-dependent mate choice, and may help identify the ligands involved in the chemical communication between potential mates.
Journal ArticleDOI
Population expansion and individual age affect endoparasite richness and diversity in a recolonising large carnivore population
Ines Lesniak,Ilja Heckmann,Emanuel Heitlinger,Emanuel Heitlinger,Claudia A. Szentiks,Carsten Nowak,Verena Harms,Anne Jarausch,Ilka Reinhardt,Gesa Kluth,Heribert Hofer,Oliver Krone +11 more
TL;DR: It is indicated that (1) immigrated wolves increase parasite diversity in German packs, and (2) prevalence of wolf-associated parasites had declined during wolf absence and has now risen during recolonisation.
Journal ArticleDOI
Complementing GPS cluster analysis with activity data for studies of leopard (Panthera pardus) diet
Marlen Fröhlich,Marlen Fröhlich,Anne Berger,Stephanie Kramer-Schadt,Ilja Heckmann,Quinton Martins +5 more
TL;DR: In this article, the authors explored a novel approach of combining both GPS cluster and activity data analysis to study the hunting activity of a single female leopard in the Cederberg Mountains of the Western Cape, South Africa.
Journal ArticleDOI
Recolonizing gray wolves increase parasite infection risk in their prey
Ines Lesniak,Ilja Heckmann,Mathias Franz,Alex D. Greenwood,Alex D. Greenwood,Emanuel Heitlinger,Emanuel Heitlinger,Heribert Hofer,Heribert Hofer,Oliver Krone +9 more
TL;DR: The results of this study demonstrate that predator–prey interactions influence parasite prevalence, if both predator and prey are part of the parasite life cycle, and mesopredators do not necessarily replace the apex predator in parasite transmission dynamics for particular parasites.
