The quill mite fauna of the Syringophilidae family (Acariformes: Prostigmata), which is associated with palaeognathous birds of the Tinamiformes order, remains poorly studied. Thus far, only two species of syringophilid mites have been documented on four species of tinamous. In this study, we present a description of a new species, sp.

Article Synopsis
  • Over 200 animal species can get infected with tularemia, but in Europe, hares and small rodents like common voles are major sources of human infections.
  • A study in the Czech Republic over 17 years revealed that hare populations significantly predict human tularemia cases, explaining 33% of yearly variations, while common voles and climate variability had little impact.
  • Despite a decline in hare numbers, human tularemia prevalence didn't decrease as expected, highlighting the importance of ongoing monitoring of hare infections as a cost-effective way to assess tularemia risk.

We studied the quill mite fauna of the family Syringophilidae, associated with bee-eaters. We examined 273 bird specimens belonging to nine closely related species of the genus , representing two phylogenetic sister clades of a monophyletic group. Our examination reveals the presence of two species of the genus , as follows: (1) a new species sp.

Article Synopsis
  • A zoophilic dermatophyte, typically known for causing rodent favus, has been associated with human infections from 2016 to 2020, particularly in the Olomouc region, which indicates a potential local outbreak.
  • Most human cases of infection were linked to contact with infected cats or dogs, highlighting the importance of direct animal-to-animal transmission.
  • Antifungal susceptibility testing revealed that terbinafine, amorolfine, ciclopirox, and efinaconazole were the most effective treatments, while fluconazole and ketoconazole showed reduced effectiveness.

Hunters in Europe gather non-survey game species population estimates to inform wildlife management, however, the quality of such estimates remains unclear. We compared estimates of game density, realized annual intrinsic growth rates, and period mean growth rates between hunter obtained data and data obtained by targeted survey methods for four species in Poland from 1960 to 2014. Raw hunter estimates were strongly positively correlated to spotlight counts of red fox (18 years of monitoring), strip counts of brown hare (21 years) and grey partridge (25 years), male call counts of partridge (24 years), and complete counts of roe deer (49 years), and not related to spotlight counts of brown hare (15 years).

The boreal forest is one of the largest terrestrial biomes on Earth. Conifers normally dominate the tree layer across the biome, but other aspects of ecosystem structure and dynamics vary geographically. The cause of the conspicuous differences in the understory vegetation and the herbivore-predator cycles between northwestern Europe and western North America presents an enigma.

The seasonal timing of avian reproduction is supposed primarily to coincide with favourable feeding conditions. Long-term changes in avian breeding phenology are thus mostly scrutinized in relation to climatic factors and matching of the food supplies, while the role of nesting mortality is largely unexplored. Here we show that higher seasonal mean daily mortality rate leads to a shift in the distribution of breeding times of the successful nests to later dates in an an open-nesting passerine bird, the red-backed shrike Lanius collurio.
