Animals often use signals to resolve aggressive interactions without resorting to physical aggression. For instance, in many bird species, melanin-based plumage traits serve as “badges of status” in settling conflicts in dominance hierarchies in winter flocks. Whether such badges are also functional as a signal in territorial interactions however is less studied. Here we ask whether the “black tie” of the great tits,Parus major,is used to assess territorial intruders by male great tits.Specifically, weperformedplayback experimentson territorial males, in which we coupled song playback with3D printed Great Tit models with narrow and wideblackties. We also includeda negative control (a monochrome gray 3D model)to ask whether great tits perceived the hand-painted 3D models as conspecific intruders. We predicteda more robust territorial response to the models with larger black-tie. Our study is expected to contribute to a better understanding the relationship between territory defense and plumage ornamentation in Great Tits.The use of 3D printed models also provide new opportunities to study the coloration signals in animals.

How lamprey muscle responds to perturbations during rhythmic motions: Phase-dependent system identification via harmonic transfer functions Nicole, Danos; Wagenbach, Christopher; Ankaralı, Mustafa Mert; Cowan, Noah; Tytell, Eric (2016-01-07) Animals can move robustly through unpredictable and complex environments. This work seeks to determine how the muscular system of the lamprey,Ichthyomyzon unicuspis, responds to deviations from a steady rhythm. In particular, we aim to understand how the muscle itself, separately from the nervous system, can react to and compensate for perturbations during periodic motion. We dissected a small section of axial musculature, approximately 5-10 mm in length, and performed standard work loop methods. We imposed...
A self-adaptive landmark-based aggregation method for robot swarms Sadeghi Amjadi, Arash; Raoufi, Mohsen; Turgut, Ali Emre (2021-01-01) Aggregation, a widely observed behavior in social insects, is the gathering of individuals on any location or on a cue. The former being called the self-organized aggregation, and the latter being called the cue-based aggregation. One of the fascinating examples of cue-based aggregation is the thermotactic behavior of young honeybees. Young honeybees aggregate on optimal temperature zones in the hive using a simple set of behaviors. The state-of-the-art cue-based aggregation method BEECLUST was derived base...
The Dilemma of Species Protection in Action Demirbaş Çağlayan, Semiha; Bilgin, Cemal Can (null; 2018-07-20) Species action plans (SAPs) can be effective tools in nature conservation. These guideline documents inform the status and threats of species and their habitats, and they identify and prioritize actions to enhance the species populations. They both disseminate and make use of useful relevant information by involving local stakeholders, natural resource managers, conservationists and decision makers. The Turkish Ministry of Forestry and Water Affairs aims to complete 100 SAPs between 2013 and 2023. Until mid...
Study of effects of selective hunting on a bear population through pva simulation Ağzıtemiz, Mehmet Melih; Bilgin, Cemal Can; Department of Biology (2008) Management of big wildlife such as bears can be a difficult task, especially in the face of human-wildlife conflict and demands of the hunting industry. The Brown Bear (Ursus arctos) population at Yusufeli County (Artvin, northeastern Turkey) has recently been the focus of scientific, social and economic concerns. This study population of c. 140 individuals occurs within 800 km2 of forested and alpine land. Legal hunting of male bears was allowed in 2007 after an interval of four years. This study aims to f...
Effects of different long-day photoperiods on somatic growth and gonadal development in Nile tilapia (Oreochromis niloticus L.) Rad, F; Bozaoglu, S; Gozukara, Se; Karahan, Arzu; Kurt, G (2006-05-31) Long-day photoperiods are considered as an effective managerial tool in manipulating somatic growth and reproduction in a number of fish species. Effects of three different artificial long-day photoperiods on somatic growth and gonadal development of Nile tilapia (Oreochromis niloticus L.) were investigated in this study. Swim-up fry with a mean initial weight of 0.06 g were exposed to 24L:0D, 20L:4D and 18L:6D artificial photoperiods and ambient light regime (control) for 24 weeks at 27.0 +/- 1 degrees C. ...
