I RUSTICA MUNERA DI CORIDONE (A MARGINE DI VERG., ECL. 2, 45-55)

2022

Within the second Eclogue, the rustica munera offered by Corydon to Alexis (vv. 45-55), while obeying a somewhat conventional plot, reveal a complex intertextual stratigraphy. Unexpectedly, δωροφόροι of di vine rank join the shepherd in paying homage to the ephebe, bringing bas kets full of lilies and a garland of flowers and herbs, to which fruits and branches of laurel and myrtle will be added. The tradition of the rubrics of στεφανωτικὰ ἄνθη, testified by Athenaeus in the 15th book of the Deipno sophistae, allows us to test both the rate of conventionality of the entire ecphrasis, and the variations made by Vergil to the lists of flowers and herbs, as well as Greek poetry as well as genr…

Analisi preliminare dello stato di conservazione in situ ed ex situ di 28 specie prioritarie di Allium L. in Italia

2020

Partendo da una checklist aggiornata delle Crop Wild Relatives presenti in Italia, si sono così selezionati i taxa a più alta priorità di conservazione del genere Allium L. (pari a 28 taxa endemici e/o inseriti nelle più recenti Liste Rosse). Si è proceduto alla determinazione della loro distribuzione sulla base di database online, fonti di erbario e bibliografiche per le quali si è effettuato il relativo georeferenziamento. Per gli scopi del presente studio, una volta riportati su mappa i punti corrispondenti alle località di rinvenimento dei taxa oggetto d’analisi, si è poi sovrapposto un layer contenente tutte le aree protette presenti sul territorio (Riserve, Parchi, siti Natura2000, ec…

Monitoring of 24-Hours Activity in a Population of Wild Boar (Sus scrofa)

2017

The aim of the study was to determine 24-hour activity of the Wild Boar at the baiting sit established in a forest ecosystem next to large scale plantations, moistly of maize. The study was based on 24-hours monitoring by camera traps. This pilot study was conducted during a year (from May 2015 to June 2016) in western Poland. Recording the exact time and date of each observation made it possible to determine the 24-hour rhythm of the studied species. Moreover, we obtained information on the seasonal change of the structure and size of the packs, and on the frequency of their occurrence at the baiting site. Changes in the size of packs over the year matched directly the animals’ breeding cy…

Monitoring wild boar (Sus scrofa) populations

2017

Celem pracy była ocena liczebności populacji dzika (Sus scrofa) z uwzględnieniem struktury wiekowo-płciowej. Badania przeprowadzono na podstawie monitoringu z wykorzystaniem fotopułapek. Obserwacje prowadzono od maja 2015 do czerwca 2016 roku w zachodniej części Polski na terenie Opolszczyzny w Nadleśnictwie Prószków, w obwodzie łowieckim Nr 48. Sezonowe wahania częstości bytowania osobników reprezentujących poszczególne klasy wiekowo-płciowe były zauważalne w składzie i wielkościach pojawiających się watah. Prowadzenie rocznych obserwacji za pomocą fotopułapek pozwala przewidywać tendencję zmian wielkości pogłowia w przyszłych sezonach na podstawie liczebności pasiaków. Z kolei zarejestrow…

Global research priorities for sea turtles: Informing management and conservation in the 21st century

2010

Over the past 3 decades, the status of sea turtles and the need for their protection to aid population recovery have increasingly captured the interest of government agencies, non-governmental organisations (NGOs) and the general public worldwide. This interest has been matched by increased research attention, focusing on a wide variety of topics relating to sea turtle biology and ecology, together with the interrelations of sea turtles with the physical and natural environments. Although sea turtles have been better studied than most other marine fauna, management actions and their evaluation are often hindered by the lack of data on turtle biology, human-turtle interactions, turtle popula…

Parasites as indicators of social structure and stock identity of marine mammals

1995

Abstract Introduction: the use of parasites as biological indicators of marine mammals has not yet received all the necessary attention. The aim of this review is to show the value of parasite data in studies of stock identity and social structure. Methods: the application of the technique to marine mammals is hampered by the lack of control over sampling conditions and the paucity of information about the biology of their parasites. Relevant criteria for, suitable parasite tags are discussed. Case studies: previous work on marine mammals is presented to illustrate the usefulness and limitations of parasite data. A study of pilot whales revealed that differences in helminth infections betwe…

Determinants of jaguar occupancy at the northern range edge

2020

Identifying factors promoting jaguar (Panthera onca) occupancy is crucial for planning effective conservation and management actions that can contribute to long-term population viability. We used camera-trapping and modeled factors affecting detection and occupancy for jaguars in Sonora at 149 sites during August-November 2008 and 2009. We measured 24 covariates presumed to affect detection (n = 6) and occupancy (n = 18) at camera sites, including sampling period and various habitat characteristics. We obtained 29 jaguar detections at 19 sites (naive occupancy = 0.12) in 5455 trap-days of effort. Jaguar detectability (p = 0.16 +/- 0.05) was negatively affected by human presence and varied b…

Numerical response of predators to large variations of grassland vole abundance, long-term community change and prey switches

2020

AbstractVoles can reach high densities with multi-annual population fluctuations of large amplitude, and they are at the base of large and rich communities of predators in temperate and arctic food webs. This status places them at the heart of management conflicts wherein crop protection and health concerns are often raised against conservation issues. Here, a 20-year survey describes the effects of large variations in grassland vole populations on the densities and the daily theoretical food intakes (TFI) of vole predators based on roadside counts. Our results show how the predator community responds to prey variations of large amplitude and how it reorganized with the increase in a domina…

The wild boar (Sus scrofa, Linnaeus, 1758) as an important reservoir host for Alaria alata in the Baltic region and potential risk of infection in hu…

2020

Abstract Alaria alata trematode is widely distributed throughout Europe and has a complex life cycle in which wild boar serve as a reservoir host. The primary aims of the present study are to establish the occurrence of A. alata mesocercariae in naturally infected wild boar in Latvia and to assess the risk for humans to acquire A. alata infection via consumption of wild boar meat. By summarizing long-term data using the Trichinella inspection method from 2014 to 2019, the overall A. alata prevalence was 8.3%, of which significantly higher A. alata prevalence was observed during the summer seasons. Additionally, 43.9% (n = 485) of wild boar were found to be infected with A. alata using Alari…
