How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Article
Full-text available
Adult wasps primary food resource is larval saliva. This liquid secretion consists mainly of amino acids and carbohydrates processed from the prey brought to the colony by the foragers. However, adults also regularly consume floral nectar. The nectar's most abundant proteinogenic amino acid is proline, and the two most abundant non-proteinogenic am...
Article
Full-text available
Despite posing a serious threat to global biodiversity, national and international management efforts have not been able to limit the spread of most invasive species. In highly dispersive species, local invasions may be followed by regional range expansion that crosses international borders. In such cases, independent management efforts of the inva...
Article
Juvenile hormone (JH) is a modulator of many physiological transitions in insects, including molting, metamorphosis, diapause, and reproduction. These processes often include metabolic changes. Here we show that JH accelerates metabolic rate in bumble bees (Bombus terrestris). We reduced JH levels in worker bumble bees by removing their corpora all...
Article
Aim Patterns of separation among males and females, known as sexual segregation, are traditionally correlated with elevation or latitude in animals. Alternatively, in humans, spatial and behavioural segregation is driven by inherent sex-based differences in thermal preference, although the cause and adaptive value of these differences remain unclea...
Article
Full-text available
Invasive species present an opportunity to test the association between selective forces and adaptive morphological traits because these species can experience rapid changes when introduced to new environments. One such invader is the common myna (Acridotheres tristis), a broadly ranging avian species that has been introduced on most continents and...
Article
Certain behavioural traits, including innovation and reduced neophobia, may facilitate successful invasions by allowing first arrivals to overcome the challenges of a novel environment. However, the extent to which these traits occur in invasive populations in comparison with native populations, and whether these traits' prevalence remains consiste...
Article
Full-text available
Estimating the potential distribution of invasive species has been primarily achieved by employing species distribution models (SDM). Recently introduced joint species distribution models (JSDM) that include species interactions are expected to improve model output. Here we compare the predictive ability of SDM and JSDM by modelling the distributio...
Article
Full-text available
Determining the distribution and potential ranges of detrimental invasive species has become an essential task in light of their impacts on the environment. However, this effort has been challenging, especially for global invaders. Our goal was to test whether potential ranges of global invaders can be predicted, and examine the factors that shape...
Article
Full-text available
Background: Genetic knowledge, which plays important functions in our understanding of science, health, social groupings, and even behaviour, has been evaluated in past studies with various populations. This wide reach of genetics means that different types of items are used to assess genetic knowledge, which restricts meaningful comparisons acros...
Article
Aim Despite the common myna's widespread distribution, and the significant impact it has caused in parts of its non‐native range, there have been no comprehensive genomic studies of its invasion of any region. We aimed to characterize the common myna invasion of the Australian continent to understand its population genetic landscape, introduction h...
Article
Populations found at the edge of a species range often have decreased genetic diversity, which together with high gene flow may reduce the ability of a species to adapt to local environmental conditions. The Dead Sea Sparrow Passer moabiticus occupies a disjointed range, where the Israeli populations are considered peripheral and fragmented. The sp...
Article
The Platyceps rhodorachis species complex encompasses a widespread group of morphologically similar colubrid snakes. The number and identities of species from this complex in Israel have recently been debated. Studies from the previous decade concluded that there are two species in Israel and its vicinity (compared with one previously recognized),...
Article

The Israeli population of Eurasian otter (Lutra lutra) marks the Palearctic southern boundary of the species' distribution in the Levant. During the 20th century, the otter population in Israel experienced a dramatic decline due to anthropogenic habitat alterations. Currently, the otter population in Israel is estimated at about 100 individuals and...

The golden jackal and red fox are among the wildlife species protected by Israeli law as enforced by the Israel Nature and Parks Authority. In 1964, as a part of a management program to control rabies in Israel, a poison eradication campaign was launched to exterminate golden jackals, considered to be the main reservoir of the disease. The program...

The project explores the factors that shape the range of the Common Myna, a broad-ranging avian invader, by studying the extrinsic (environmental) and intrinsic (behavioral, genomic, morphological) characteristics of native and introduced common mynas.
