This case study describes the diagnosis of clinical toxoplasmosis in two meerkats (Suricata suricatta) from the Safari-zoological center, Tel Aviv-Ramat Gan. The meerkats showed neurological signs such as incoordination, lethargia, anorexia and one of them died. Gross pathology revealed diffuse...

Animals play an important role in the seed dispersal of many plants. It is increasingly recognized, however, that the actions of a single disperser rarely determine a seed's fate and final location; rather, multiple abiotic or animal dispersal vectors are involved. Some carnivores act as secondary...

Plants with animal-dispersed fruits seem to overcome the barriers that limit their spread into new habitats more easily than other invasive plants and, at the same time, they pose special difficulties for containment, control or eradication. The effects of animals on plant propagules can be very...

The fish Perccottus glenii was introduced into Europe one hundred years ago from Eastern Asia, with several initial introduction points. We used parasitological analysis to verify homogeneity-of-origin of P. glenii populations in the middle part of a large river basin where this invasive fish was...

Climate change is an additional stressor in a complex suite of threats facing freshwater biodiversity, particularly for cold-water fishes. Research addressing the consequences of climate change on cold-water fish has generally focused on temperature limits defining spatial distributions, largely...

Trichinellosis is one of the most important foodborne zoonotic diseases, with worldwide distribution. While human risk for trichinellosis has historically been linked to pork, modern pork production systems and slaughter inspection programs have reduced or eliminated pork as a source for...

Disturbances, or changes in disturbance regimes, can promote invasions, but invasives can also be seen as drivers of disturbances. Non-native species can either change an existing disturbance regime or introduce disturbance regimes that are novel to the invaded system. Changes in disturbance...

The invasion of ecosystems by non-native species may alter the nitrogen (N) cycle through different nonexclusive mechanisms. Dramatic alterations occur in an ecosystem when the invasive species possesses a new strategy to acquire this nutrient, such as N₂ fixation ability. Gradual alterations are...

Land-use change and invasive species pose major threats to ecosystems globally. These stressors can act together, with disturbance due to changes in land-use facilitating invasion. We examined the potential for agricultural land use to facilitate the establishment and population growth (abundance)...
