Fish communities in the shallow waters (9–20 m depth) of outer Malangen (69 o N), Northern Norway was studied to investigate effects season, bottom substrate associations and population dynamic parameters on fish assemblages. In four fieldtrips during one year at locations, were sampled by trammel nets composition monitored underwater video. A total 16 species caught, including from Pleuronecti...

—Linnaeus described 37 species of flower flies (Diptera: Syrphidae). His collection was studied, and the current status of all his flower fly names is given. Six new synonyms are established (Scaeva annulipes Zetterstedt = Eriozona erratica (Linnaeus), Musca citrofasciata DeGeer = Xanthogramma /estiva (Linnaeus), Xylota curvipes Loew = Chalcosyrphus femoratus (Linnaeus), Chrysogaster chalybeata...

This study investigated the feeding habits of Raja miraletus Linnaeus, 1758 and Dipturus oxyrinchus (Linnaeus, 1758). For purpose this study, specimens were obtained monthly from commercial trawlers operating around Gökçeada Island in Northern Aegean Sea between February 2019 2020. A total 29 (24 female 5 male) brown rays (Raja miraletus) 36 (20 16 longnosed skates (Dipturus oxyrinchus) capture...

Entomological collections are an invaluable source of data, due to the variety species they contain, capturing biodiversity a given time. Thus, entomology part Division Zoology Collection (Faculty Science, Department Biology), in Zagreb, established 1890, is important asset for all faunistic research and any overview historical changes composition, as well resource education young scientists. H...

We investigated the ecological requirements in emergence phase of two congeneric species Aeshnidae, Aeshna grandis (Linnaeus 1758) and A. juncea 1758), occurring syntopy at southernmost limit their range. sampled exuviae peak three lakes NW Italy. In each lake we defined 30 to 50 sampling plots along borders where checked for presence collected data on microhabitat composition. By modeling resp...

The prevalence of animal rabies differs in each area of Mongolia. Wolves (Canis lupus Linnaeus, 1758), foxes ( Vulpes vulpes Linnaeus, 1758), corsac foxes (Vulpes corsac Linnaeus, 1768) and manuls (Felis manul Pallas, 1778) are considered to be the infective wild animals in natural foci. Amongst livestock, cattle have had the most rabies cases, followed by camels, sheep, goats and horses. The p...

To assess the relationship between predation risk perceived by elk (Cervus elaphus L., 1758) as evidenced by vigilance, we conducted focal animal observations in elk winter range.We stratified our observations in Glacier National Park, Montana, USA, andWaterton Lakes National Park, Alberta, Canada, in valleys with three wolf (Canis lupus L., 1758) population levels (Saint Mary Valley: no wolf; ...

BACKGROUND Chrysomelid beetles associated with willow (Salix spp.) were surveyed at 41 sites across Europe, from Greece (lat. 38.8 °N) to arctic Norway (lat. 69.7 °N). NEW INFORMATION In all, 34 willow-associated chrysomelid species were encountered, of which eight were very abundant. The abundant species were: Crepidodera aurata Marsham, 1802 at 27 sites, Phratora vitellinae (Linnaeus, 1758)...

Rising ocean temperatures are causing marine fish species to shift spatial distributions and ranges, and are altering predator-prey dynamics in food webs. Most documented cases of species shifts so far involve relatively small species at lower trophic levels, and consider individual species in ecological isolation from others. Here, we show that a large highly migratory top predator fish specie...

Food acquisition and predation avoidance are key drivers of herbivore behaviour. We investigated the interaction of top-down (predator) and bottom-up (food, fire, thermal) effects by measuring the relationship between wolf (Canis lupus L., 1758) predation risk perceived by elk (Cervus elaphus L., 1758) and elk landscape use. We conducted fecal pellet and wolf scat surveys in three valleyswith t...
