Third-instar Oestrus caucasicus larvae (n = 236) obtained from Iberian ibex, Copra pyrenaica, were reared in a laboratory to obtain adult flies. They were maintained at a temperature of 21.9 +/- 2.7 degrees C and a relative humidity of 38.9 +/- 8.0 %. In all, 78 imagos emerged (33.1 %), with a sex-ratio at emergence not differing significantly from 1:1; 25 larvae did not complete pupariation. A...
Resonant orbits have been widely employed in mission design for planetary flyby trajectories (JEO) and, more recently, as a source of long-term stability (IBEX). Yet, resonant orbits have not been explored extensively as transfer mechanisms between non-resonant orbits in multi-body systems. To highlight the benefit of employing resonant orbits for transfers and given the increased interest in e...
We adapt smoothing methods to histogram-valued time series (HTS) by introducing a barycentric histogram that emulates the "average" operation, which is the key to any smoothing filter. We show that, due to its linear properties, only the Mallows-barycenter is acceptable if we wish to preserve the essence of any smoothing mechanism. We implement a barycentric exponential smoothing to forecast th...
A computer program, VVF, has been developed to assess the suitability of a territory as habitat for a species. It integrates several types of Habitat Suitability models into a Geographical Information System. In addition to standard GIS functions, VVF allows a user to create, modify and store new Habitat Suitability models for different species, to create Habitat Suitability maps by running Hab...
The PNAS article by Stiner et al. (1), “A forager–herder trade-off, from broad-spectrum hunting to sheep management at Aşıklı Höyük, Turkey,” adds a major new element to our evidence for—and understanding of— the appearance of the first animal herding in southwest Asia, involving the earliest management of caprines (managed caprines including sheep and goat), as well as an important methodologi...
this syndrome is a shock-like hyper metabolic myopathy triggered in susceptible animals by stress. capture myopathy (c.m.) is a commonly occurring condition in mammals following trapping and transportation. in this case 12 to 24 hours after transportation of red deer (cevus elaphus) and wild goats (capra ibex) clinical signs such as: muscular tremor, ataxia, recumbency, hyperthermia, tachyca...
We analyze the hedging effectiveness of positions that replicate stock indexes using corresponding futures contracts through the application of a dynamic, stochastic hedging strategy proposed by Lafuente and Novales (2003). Conclusive gains do not emerge in any of the markets analyzed over the period considered, relative to the use of a constant unit hedge ratio. These findings are consistent w...
The aim of the present study is to develop an assay for the specific identification of meat from Capreolus capreolus, Cervus elaphus, Capra ibex, Rupicapra rupicapra, targeting sequences of the cytochrome b (cyt b) gene of mitochondrial DNA. The assay is also intended to enable differentiation between meat from these wild species as well as Ovis aries, Capra hircus, Bubalus bubalis, Bos taurus ...
