Animals living in urban areas experience additional stress compared to those inhabiting
more natural habitats. This could influence their physical state and ability to cope with …

Identifying factors influencing infection patterns among hosts is critical for our understanding
of the evolution and impact of parasitism in natural populations. However, the correct …

Host abundance might favour the maintenance of a high phylogenetic diversity of some
parasites via rapid transmission rates. Blood parasites of insular lizards represent a good …

Modern studies have shown how parasites add extra complexity to ecosystems through their
potential effects on hosts. Blood parasites are common in lizards and various studies have …

Background Blood parasites of the genus Karyolysus Labbé, 1894 (Apicomplexa: Adeleida:
Karyolysidae) represent the protozoan haemogregarines found in various genera of lizards …

Blood parasites such as haemogregarines and haemosporidians have been identified in
almost all groups of vertebrates and may cause serious damages to their hosts. However …

Parasites are able to negatively affect the locomotor performance of their hosts, and
consequently, their biological fitness. In this study, we examine the relationship between …

Nowadays it is widely accepted that parasites play a significant role in the community
structures in which they occur, and ultimately upon ecosystems. Furthermore, infection by …

In animals, developmental stability is frequently assessed by the level of fluctuating
asymmetry. Several environmental and genetic stress factors can increase the …

The ability of vertebrates to evolve different defence strategies in response to varying
parasitism regimes remains poorly understood. Hosts may adopt two different strategies to …
