This section introduces important animals that are not regarded as causing fairy circles. It is rather assumed they take advantage of resources and structures provided by Some them directly use the Sand termites a food resource (e.g. Aardvark), others occupy various positions within webs at circles Seothyra spiders feeding on Tetramorium ants which forage Psammotermes). Others seem to simply ma...

Chemical immobilization is an important tool for the capture, study, and management of wildlife. Increased regulation traditional opioids has necessitated a search alternative drugs in wildlife capture. Butorphanol–azaperone–medetomidine (BAM) one promising that been used range taxa, though often on medium-size mammals using ground-based methods. We tested efficacy BAM via remote delivery from ...

Zebrafish larvae show characteristic prey capture behavior in response to small moving objects. The neural mechanism used to recognize objects as prey remains largely unknown. We devised a machine learning behavior classification system to quantify hunting kinematics in semi-restrained animals exposed to a range of virtual stimuli. Two-photon calcium imaging revealed a small visual area, AF7, t...

ABSTRACT We study the capture of interstellar objects (ISOs) by a planet–star binary with mass ratio q ≪ 1, semimajor axis ap, orbital speed vc, and eccentricity ep. Very close (slingshot) wide encounters planet are amenable to analytical treatment, while numerically obtained cross-sections σ closely follow results even in intermediate regime. Wide interactions can only generate energy changes ...

Trap-awareness and related phenomena whereby successive capture events are not independent is a feature of the majority of capture-recapture studies. This phenomenon was up to now difficult to incorporate in open population models and most authors have chosen to neglect it although this may have damaging consequences. Focusing on the situation where animals exhibit a trap response at the occasi...

Jolly (1982, Biometrics 38, 301-321) presented modifications of the Jolly-Seber model for capture-recapture data, which assume constant survival and/or capture rates. Where appropriate, because of the reduced number of parameters, these models lead to more efficient estimators than the Jolly-Seber model. The tests to compare models given by Jolly do not make complete use of the data, and we pre...

Detection of animals which are persistently-infected with bovine virus diarrhoea virus (BVDV) is of prime importance in the control of pestivirus infections in cattle, as these animals constitute the main reservoir of the virus. Identification of such animals can be readily performed using crude whole blood samples with a sandwich enzyme-linked immunosorbent assay (ELISA) requiring only approxi...

How can stakeholders within the fisheries community engage in constructive ethical discussions? Drawing on experiences from previous debates surrounding the human use of animals, this paper presents a proactive approach whereby stakeholders can create a framework for ethical discussion of capture fisheries.
