  Title Dog rivalry impacts following behavior in a decision-making task involving food Type Journal Article
  Year 2017 Publication Animal Cognition Abbreviated Journal Anim. Cogn.  
  Volume Issue Pages 1-13  
  Keywords  
  Abstract Dogs learn a great deal from humans and other dogs. Previous studies of socially influenced learning between dogs have typically used a highly trained demonstrator dog who is unfamiliar to the observer. Because of this, it is unknown how dynamics between familiar dogs may influence their likelihood of learning from each other. In this study, we tested dogs living together in two-dog households on whether individual dogs’ rivalry scores were associated with performance on a local enhancement task. Specifically, we wanted to know whether dog rivalry impacted whether an observer dog would approach a plate from which a demonstrator dog had eaten all available food, or whether the observer dog would approach the adjacent plate that still contained food. Dog rivalry scores were calculated using the Canine Behavioral Assessment and Research Questionnaire and indicated each dog’s tendency to engage aggressively with the other household dog. Low-rivalry dogs were more likely to approach the empty plate than high-rivalry dogs when the observer dog was allowed to approach the plates immediately after the demonstrator had moved out of sight. This difference between low- and high-rivalry dogs disappeared, however, when observer dogs had to wait 5 s before approaching the plates. The same pattern was observed during a control condition when a human removed the food from a plate. Compared to low-rivalry dogs, high-rivalry dogs may pay less attention to other dogs due to a low tolerance for having other dogs in close proximity.

  Title Framing pictures: A conceptual framework to identify and correct for biases in detection probability of camera traps enabling multi-species comparison Type Journal Article
  Year 2019 Publication Ecology and Evolution Abbreviated Journal Ecol Evol  
  Volume Issue Pages  
  Keywords animal characteristics; detectability; environmental variables; mammal monitoring; reuse of data; trail camera  
  Abstract Abstract Obtaining reliable species observations is of great importance in animal ecology and wildlife conservation. An increasing number of studies use camera traps (CTs) to study wildlife communities, and an increasing effort is made to make better use and reuse of the large amounts of data that are produced. It is in these circumstances that it becomes paramount to correct for the species- and study-specific variation in imperfect detection within CTs. We reviewed the literature and used our own experience to compile a list of factors that affect CT detection of animals. We did this within a conceptual framework of six distinct scales separating out the influences of (a) animal characteristics, (b) CT specifications, (c) CT set-up protocols, and (d) environmental variables. We identified 40 factors that can potentially influence the detection of animals by CTs at these six scales. Many of these factors were related to only a few overarching parameters. Most of the animal characteristics scale with body mass and diet type, and most environmental characteristics differ with season or latitude such that remote sensing products like NDVI could be used as a proxy index to capture this variation. Factors that influence detection at the microsite and camera scales are probably the most important in determining CT detection of animals. The type of study and specific research question will determine which factors should be corrected. Corrections can be done by directly adjusting the CT metric of interest or by using covariates in a statistical framework. Our conceptual framework can be used to design better CT studies and help when analyzing CT data. Furthermore, it provides an overview of which factors should be reported in CT studies to make them repeatable, comparable, and their data reusable. This should greatly improve the possibilities for global scale analyses of (reused) CT data.

  Title Typologie der deutschen Pferdehaltung – Eine empirische Studie mittels Two-Step-Clusteranalyse Type Journal Article
  Year 2016 Publication Zeitschrift für Agrarpolitik und Landwirtschaft Abbreviated Journal Z. Agrarpolit. Landwirtsch.  
  Volume 94 Issue 3 Pages  
  Keywords  
  Abstract In der deutschen Pferdebranche besteht u. a. hinsichtlich der Ausrichtung, Lage, Größe und ökonomischen Zielsetzung von Pferdehaltern eine große Heterogenität, gleichzeitig sind die Strukturen in diesem Sektor bislang kaum wissenschaftlich erfasst. Aus diesem Grund wird im vorliegenden Beitrag die Vielzahl unterschiedlicher Erscheinungsformen in der Pferdehaltung mittels einer empirisch gestützten Typologie systematisch beschrieben. Mittels einer standardisierten Onlinebefragung wurden 1.110 private, landwirtschaftliche und gewerbliche Pferdehalter sowie pferdehaltende Vereine befragt. Abgefragt wurden neben der Organisationsform, Bestandsgröße und der Ausrichtung auch Aspekte wie u. a. die Ausstattung der Anlage, die angewandten Haltungssysteme für die Pferde sowie Angaben zur zukünftige Entwicklung und den wahrgenommenen aktuellen sowie zukünftigen Herausforderungen in der Pferdehaltung. Mittels einer Clusteranalyse konnten sechs Typen herausgearbeitet werden: ländliche Hobbypferdehaltung, stadtorientierte Hobbypferdehaltung, Hobby-Zuchtpferdehaltung, Zuchtpferdehaltung, Pensionspferdehaltung und diversifizierte Pferdehaltung. Dabei sind die drei erstgenannten Typen der Liebhaberei zuzuordnen und die drei letztgenannten Typen werden mit Gewinnerzielungsabsicht betrieben. Die ermittelten Typen unterscheiden sich teilweise signifikant u. a. hinsichtlich ihrer Größe, den angewandten Haltungssystemen, der Anzahl an Betriebszweigen oder auch ihren zukünftig geplanten Entwicklungen. Die vorliegende Studie zeigt somit, dass beispielsweise bei der Entwicklung politischer Maßnahmen im Bereich der Pferdehaltung die Auswirkungen für einzelne Pferdehalter sehr unterschiedlich ausfallen können und es daher notwendig ist, die unterschiedlichen, real existierenden Betriebstypen zu berücksichtigen.

  Title Wolf depredation on livestock in central Greece Type Journal Article
  Year 2009 Publication Mammal Research Abbreviated Journal Mamm. Reas.  
  Volume 54 Issue 1 Pages 11-22  
  Keywords  
  Abstract We studied wolfCanis lupus Linnaeus, 1758 -- livestock conflict in central Greece by investigating patterns of 267 verified wolf attacks on livestock for 21 months. Wolves attacked adult goats 43% and cattle 218% more than expected, whereas sheep 41% less than expected from their availability. Wolves killed less than four sheep or goats in 79%, and one cow or calf in 74% of depredation events, respectively. We recorded higher attack rates during wolf post-weaning season. Wolf attacks on strayed, or kept inside non predator-proof enclosures, sheep and goats, were on average two to four times respectively more destructive than those when livestock was guarded by a shepherd. Sheepdog use reduced losses per attack. Optimal sheepdog number ranged from 3 to 9 animals depending on flock size. Losses per attack were positively related to the number of wolves involved. Total losses per farm were positively correlated with the size of livestock unit but percentage losses per capita increased with decreasing flock size. Management implications to mitigate livestock depredation are discussed.
