Conservation implications of shifting habitat use in migrating insects: Selection patterns in a threatened damselfly show that season‐specific actions are needed

open access: yesInsect Conservation and Diversity, EarlyView.
Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

The Log-Behavior of Some Sequences Related to the Generalized Leonardo Numbers

open access: yes
Summary: Let \(\{\mathcal{L}_{k,n}\}_{n \geq 0}\) denote the generalized Leonardo sequence, where \(k\) is a fixed positive integer. In this paper, we discuss the log-behavior of some sequences related to \(\mathcal{L}_{k,n}\). For example, we show that the sequences \(\{\sqrt[n]{\mathcal{L}_{k,n}}\}_{n\geq 9}\) and \(\{\mathcal{L}^n_{k,n}\}_{n \geq 3}\

Passive transponder implantation in Theraphosidae: A tool for traceability and conservation

open access: yesInsect Conservation and Diversity, EarlyView.
PIT TAG microchip implantation was successfully performed in multiple tarantula species, showing high tolerance, rapid recovery from anaesthesia and no mortality associated with the procedure. Microchips remained stable and detectable after successive ecdysis events, with no negative effects on feeding behaviour, development, courtship, mating success ...

Pairwise Imitation and Tournament Graphs

open access: yesInternational Economic Review, EarlyView.
ABSTRACT This paper investigates strategic dynamics under the behavioral rule of pairwise interact and imitate (PII), which requires minimal information and emphasizes outperforming opponents in pairwise interactions. We characterize PII using weak tournament graphs and, for a broad class of dynamics, establish a one‐shot stability result for ...

The Role of Dice in the Emergence of the Probability Calculus

open access: yesInternational Statistical Review, EarlyView.
Summary The early development of the probability calculus was clearly influenced by the roll of dice. However, while dice have been cast since time immemorial, documented calculations on the frequency of various dice throws date back only to the mid‐13th century.

The Role of Newsreels in the Modernization of Cities: More than just Propaganda

open access: yes, 2015
The film propaganda of newsreels (i.e. news presentations screened in cinemas and associated with weekly programming) constitute an archive of particularly important documents for those researching urban subjects (e.g.

A new, conspicuously pigmented Pyrrhulina (Teleostei: Characiformes: Lebiasinidae) from the Río Tigre, Loreto, Peru

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of Pyrrhulina is described based on morphological and molecular evidence. Pyrrhulina punctata is distinguished from all congeners by the presence of a series of 7 to 16 irregular blotches of dark pigmentation on the flanks, equally marked in juveniles and adult specimens, the presence of 26–28 lateral‐line scales, 17–21 maxillary

Recensione dell'Articolo: (Vlasiou, M.; Yechiali, U. - " M/G/∞polling systems with random visit Times " - Probab.Engrg.Inform.Sci. 22 (2008), no.1, 81–105.)

open access: yes, 2009
In this paper the authors define an infinite server polling system. They propose to use the model to simulate the behaviour of vehicular traffic in a cross-road which is controlled by a semaphore system.

A new Hyphessobrycon (Characiformes: Acestrorhamphidae) of the Hyphessobrycon agulha lineage of Hyphessobryconinae from the lower Aripuanã basin, Brazil, with comments about the lineage

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of Hyphessobrycon is described from a tributary of Rio Jatuarana, lower Rio Aripuanã basin, Rio Madeira basin, Apuí, Amazonas. The new species is part of the Hyphessobrycon agulha lineage, with the typical midlateral narrow black stripe immediately followed dorsally by an iridescent stripe.
