Yeakel et al. (1) find that wild mammal extinction in ancient Egypt during the Holocene was nonrandom and coincided with abrupt climatic changes and a local cultural collapse. The authors provide compelling evidence that the deterioration of the natural Egyptian ecosystem gradually progressed during the Holocene. The extinction patterns provided vividly show that decreasing predator and prey (u...

Alveolar echinococcosis (AE) caused by Echinococcus multilocularis can infect humans as a dead-end host. They matured in canid’s intestine (e.g. foxes, jackals, wolves, dogs, cats, etc.). AE is seen across the world. It has a high prevalence in the central and northern parts of Europe, North America and Asia. The prevalence of AE was low in the past, even in hyper endemic regions. But in ...

The present study determined the occurrence of Trichinella spp. in captured and some perished wildlife animals which included 70 hedgehogs, 19 red foxes, 13 common jackals and 8 crested porcupines in northwestern Libya. Muscle samples of these animals were examined by trichinoscopy. Trichinella larvae were detected only in 4 (5.7%) of the hedgehogs (Erinaceus algirus) and 2 (10.5%) of the red f...

trichinellosis is both of veterinary and medical importance in countries where pig breeding and pork consumption exists. in iran, people are forbidden to consume pork because of the religious regulations. therefore, there have not been any human cases over the past decades except a doubtful case based on serological test. although there are some sylvatic trichinellosis in wild life in different...

An approach to modelling food web biomass flows among live and dead compartments within and among species is formulated using metaphysiological principles that characterise population growth in terms of basal metabolism, feeding, senescence and exploitation. This leads to a unified approach to modelling interactions among plants, herbivores, carnivores, scavengers, parasites and their resources...

Visual Analytics is a relatively new field which tries to combine and intertwine visual and analytical methods in an interactive manner. Because of the complex structure of time, the application of visual analytics methods to timeoriented data is a very promising approach for insight generation. To show how this can be applied, on top of real world data we created a fictitious scenario where ev...
