Analysis of spatiotemporal partitioning is pivotal to shed light on interspecific coexistence. Most research effort has involved large-sized carnivores and their prey, whereas little attention has been devoted to lagomorphs. We assessed spatiotemporal overlap among the European brown hare Lepus europaeus and its potential competitors and predators through camera-trapping in an area in Central Italy. We estimated the interspecific patterns of the spatiotemporal activity rhythms of brown hares, its potential predators (the red fox Vulpes vulpes, the pine marten Martes martes, the domestic cat Felis catus, and the domestic dog Canis familiaris), and a competitor, the roe deer Capreolus capreolus. Brown hare activity was studied in natural conditions as well as in a fenced area that excluded terrestrial predators and competitors. Free-ranging hares developed a more nocturnal behavior to avoid diurnal predators (i.e., domestic carnivores and martens). Although high temporal overlap was observed between free-ranging brown hares and both red foxes (82%) and roe deer (81%), hares avoided fox by being more active on darkest nights, as well as avoided roe deer through spatial partitioning. We suggest that hares may adapt their spatiotemporal behavior to avoid potential predators and competitors.

The genus Hystrix includes eight species of porcupines distributed in Eurasia and Africa, across a broad latitudinal gradient. Our aim was to assess whether porcupine skulls: (1) allow for a reliable interspecific distinction; (2) change in size proportionally with body size; (3) follow the Bergmann's rule. We measured 235 Hystrix skulls from museums and private collections. We tested for differences in skull size and we assessed whether variability in skull shape allows species recognition through a multivariate approach. All Hystrix species considered could be reliably identified by skull shape. Skull size was correlated with body size and species differed in skull shape and size, with skulls of Hystrix javanica and Hystrix africaeaustralis being respectively the smallest and the largest ones. Within Hystrix cristata, the Mediterranean and the sub‐Saharan clades differed for both skull size and shape. Using skull size, we could distinguish among African, mainland Italian and Sicilian populations. Skull size of this species decreased in size for increasing latitude values, contrary to prediction by the Bergmann's rule. Such latitudinal pattern may depend on the adaption of H. cristata to Equatorial African conditions, where the species evolved. In Italy (where H. cristata was introduced in the VI Century AD) and in North Africa, a smaller body size may be due to the local climate, or to a ‘founder effect’.

Due to the urbanization and human invasion of the natural environments, great changes have been occurred on the food composition and feeding ecology of several animals especially those are sharing human his habitat in fields, wadis and gardens. The desert hedgehogs Paraechinus aethiopicus populations inhabiting different localities in Saudi Arabia were studied by using stomach contents analysis between February 2015 and October 2019. Precise analysis of stomach contents of 55 hedgehogs showed that the food of P. aethiopicus is highly diverse and highly influenced with effect of human on the environment including cooked rice, insects, plant materials, eggshells, worms, garbage and remnants of mammals and birds. Diet composition showed seasonal variations that are apparently associated with changes in the availability of different food items. The present results clearly showed that P. aethiopicus is an omnivorous mammal, capable of adapting to a great variety of dietary compositions in the study sites.

The Egyptian red fox (Vulpes vulpes aegyptiaca) and Egyptian Baladi dog (Canis familiaris) are two members of the Family Canidae that are widely distributed in Egypt. The skulls of different Canid species vary greatly in their size and shape; therefore, they can be used as a tool to study the evolution and evolutionary history of these animals. The craniometric measurements are crucial for species identification and determination of the specific sites for nerve blocks. The present study compared the craniometric measurements of the red fox and Baladi dog skulls by measuring 47 parameters on each skull and calculation of 8 indices. The red fox skull had significantly lower values of 41 craniometric measurements (approximately 87% of the measurements done), including skull length, width, and height, cranial length and width, palatal and mandibular length, and dental measurements. In contrast, the red fox had significantly higher values of only 3 measurements (approximately 6% of the measurements done) including the tympanic bulla measurement. While only three skull measurements did not differ significantly between the red fox and dog. Statistics revealed that domestic dog had significantly higher values of foramen magnum and palatine indices, and significantly lower value of nasal index than those of red fox. The present work reported variations in the gross and craniometric measurements of skull between the red fox and dog. The measured cranial parameters of both adult animals provide valuable information that can be used in ecological studies, comparative anatomy, and clinical veterinary sciences.

Insect fauna of Libya is poorly studied. The insect fauna recorded from Misurata, northwestern Libya is represented by 16 orders, 59 families and 77 genera all are arranged alphabetically. The verification and corrections will be available in a detailed work revising different insect orders and families of Libya. This work is considered the first checklist of insects in Libya at all.
