Accurately assessing the natural variation in biodiversity is crucial as a baseline for monitoring trends and attributing them to natural or anthropogenic drivers. To assess this baseline, we estimated the species richness, composition and abundance of plants, beetles and ants in Evolution Canyon II (Israel), a protected reserve in the Eastern Medi...

The State of Nature Reports have been published since 2010 by Hamaarag. The reports present ecosystem trends and processes in Israel and provide a glimpse into the state of nature in Israel. The State of Nature Report 2023 – Biodiversity Volume is largely based on analyses of data accumulated during the first decade of the National Terrestrial Moni...

The State of Nature Report organizes and presents spatial and temporal information on the threats to our ecosystems and the significant processes impacting both ecosystems and biodiversity. The report aims to provide a scientific basis for developing informed, sustainable management regimes for open landscapes and biodiversity in Israel. Trends and...

The carabids of the tribe Platynini from the southern Levant (Egypt: Sinai Peninsula, Israel, Jordan) and adjacent regions of Egypt, Lebanon, Syria, Iraq, and Saudi Arabia are reviewed in terms of species taxonomy, ecological, distributional traits, and conservation biology. In addition to a classical dichotomous identification key to the 14 specie...

eight species of the ground beetle genus Calosoma are reported from the southern levant (egypt (sinai), Israel, Jordan) and adjacent areas in egypt, Iraq, le ba-non, saudi arabia, and syria. the reports of one species were probably due to mislabelling. an illustrated identification key for the species in the region is provided. the current state of...

Careful consideration of the cost-effectiveness of wildlife-friendly practices is key to promote fit-for-purpose agro-ecological policies, but quantitative evaluations of economic costs and ecological benefits compared to other land management alternatives are scarce. We compared the cost-effectiveness of uncultivated field-margins, a widespread wi...

In the face of the decline of many insects, there is an increasing demand for contemporary, fast and cost-effective approaches to monitor the development of populations and species. Numerous scientists favor molecular methods, especially those involving barcoding of the CO1 gene, as an alternative to classical, morphology-based species identificati...

The south-west Palaearctic Graphipterus serrator group is revised. The systematic concept of the G. serrator group has undergone many changes during the last two centuries, and several different classifications have been published in recent decades. Here, the numerical taxonomy approach is used with the morphologi¬cal characterization similarity le...

The tiger beetles of the southern Levant (Egypt: Sinai, Israel, Jordan) and adjacent regions of the neighboring countries Lebanon, Syria, Iraq, Saudi Arabia and Egypt are reviewed in terms of species taxonomy, ecological and distributional traits and conservation biology. An illustrated dichotomous identification key from the species of this region...

Based on the study of approximately 400 specimens, we give an overview of the systematics and taxonomy, distribution, dispersal power, and habitat preferences of the carabids belonging to the tribes Anthiini, Helluonini, Dryptini, and Zuphiini in the southern Levant (Egypt: Sinai, Israel and Jordan). We provide identification keys for the members o...

The members of the carabid beetle tribe Cyclosomini s.l. in Israel and adjacent regions (Lebanon, Syria, Jordan and Egypt) are studied in terms of taxonomy, ecology (including the traits power of dispersal, especially hind wing development, and phenology), and distribution patterns. Material from museum collections and the authors’ field trips is a...

Based on the study of approximately 700 specimens, we give an overview of the systematics and taxonomy, distribution, dispersal power, and habitat preference of the ground beetles belonging to the tribe Trechini in Israel. We provide an identification key to all Trechini species in Israel (and the adjacent regions in Lebanon, Syria, Jordan and Egyp...

The way information is represented by sequences of action potentials of spiking neurons is determined by the input each neuron receives, but also by its biophysics, and the specifics of the circuit in which it is embedded. Even the "code" of identified neurons can vary considerably from individual to individual. Here we compared the neural codes of...

A comparison between codewords of different sexes. Matrix of the Jensen Shannon distances between 8-letter word distributions of each pair of flies, similar to figure 2B, but clustered according to sex. Bars show mean values+SEM of the distances within each of the two clusters. (TIF)

תקציר אובדן והרס בתי גידול נתפס כגורם המשמעותי ביותר לצמצום מגוון המינים בעולם. מרבית המחקרים בנושא זה עוסקים בהשפעות ישירות ועקיפות של פעילות האדם על מצב בית הגידול, אולם, במקרים מסוימים, דווקא הפסקה בפעילות אדם מסורתית היא הגורם לאבדן בית גידול ייחודי. במחקר זה נבחנה השפעת תהליך אובדן בית הגידול החולי כתוצאה מהפסקת רעייה על הרכב חברת פרוקי-הרגליי...
