Despite the widespread coexistence of three guilds of the bovid family — deer [red deer (Cervus elaphus) and roe deer (Capreolus capreolus)], gazelles [goitered gazelle (Gazella subgutturosa) and chinkara (Gazella bennettii)], and goats [bezoar goat (Capra aegagrus), Armenian mouflon (Ovis gmelini) and urial (Ovis vignei)] — in southwestern Asia, detailed information on their habitat selection and niche partitioning is lacking. We used species distribution models (SDMs) based on MaxEnt to assess the suitability of habitats for these species. The results showed that MaxEnt models with the area under the ROC curve (AUC) > 0.85 had a good predictive value. The highest and lowest habitat overlaps were obtained for red deer/roe deer (35.4%) and goitered gazelle/chinkara (3.6%), respectively. Our results provide information on habitat selection and niche partitioning in the studied bovids which can improve their conservation efforts.

We explored the unusual position, anatomy and evolutionary significance of the position of the horns in Bos taurus. In the genus Bos, the frontal bone, frontal sinus and parietal bones are shifted and repositioned. A new occipital (pseudo-occipital) crest forms at the edge of the calvaria. The true occipital crest has shifted to the back along with the parietal. The frontal sinus has overridden a parietal sinus. We compared this bone reorganization with the anatomy of deer (Dama and Odocoileus), a gazelle (Gazella dorcas) and a bovid (Eotragus clavatus) in which the bones are in the primitive positions. The fetal Bos has a fontanelle which is not seen in Gazella or Odocoileus. An evolutionary succession can be developed based on the backward shift of the frontal and horns in Bos taurus and other Bovini.

Invasive predators contributed to recent extinctions worldwide, including endemic birds. We monitored nests of two endemic birds in the Atlantic Forest, the serra antwren (Formicivora serrana littoralis) and the sooretama slaty antshrike (Thamnophilus ambiguus) during two consecutive breeding seasons, to estimate predation rates and identify the predators. As invasive marmosets apparently became locally common, we hypothesized that they would prey upon natural nests at a higher rate than native predators. We found 13 nests of the antwren and 15 of the antshrike, of which 100% and 73%, respectively, were preyed upon. Invasive marmosets preyed upon 13 of 16 nests (81%) with identified predators, affecting 90% and 67% of the antwren and the antshrike nests. This study documented that invasive primates negatively affect the breeding success of native birds in Brazil. We highlight the need for urgent measures to manage invasive marmosets to avoid the local extirpation of the endemic birds.

An accurate estimation of growth is crucial for any fish species that is a target in fishery. We applied a biphasic Lester model for pikeperch (Sander lucioperca) population that is a slow-growing one. In this model, age at maturity divide the growth into immature and matuire phases. Logistic regression models showed that both age and length were significant in males and females when using maturity as a dependent variable, and both of these variables differed between sexes. To estimate how the changes in used age at maturity affect the Lester model parameters, the effects of ages from 10% to 90% probability of maturity were analysed. The gonadosomatic index of males (max. 2%) and females (max. 8.6%) was used to select Lester models that also gave low estimates for the investments in reproduction (g). Low g values were found in the Lester models for ages from 60% to 90% probability of maturity in males, and from 30% to 70% in females.

Habitat associations of small mammals are an essential component of ecosystem functioning. We studied habitat associations of small mammals during an 8-year period in a hemiboreal forest–farmland landscape. We observed all five rodent and one shrew species in meadows, three species in forests, and two species in crop fields. Total abundance was evenly distributed across the three main habitat types but was biased towards habitat margins. The bank vole, Myodes glareolus, was associated with mature and middle-aged forests and avoided meadows; it was absent from crop fields. The yellow-necked mouse, Apodemus flavicollis, occurred in all three main habitat types, without significant associations. However, its relative abundance was significantly higher in dry natural meadows and mid-successional forests, and it also favored ecotones. The striped field mouse Apodemus agrarius preferred crop fields and unmanaged meadows over forests. The vital hemiboreal small mammal community requires the preservation of heterogeneous forest–farmland complexes.

Georthocladius meluensis and G. techensis are described and illustrated based on material collected from glacial springs and streams in Corsica and Eastern Pyrenees. The two new described species can be separated from other members of the genus by the shape of sensilla coeloconica, tergite IX, anal point, virga, inferior volsella and gonostylus. Currently, the genus Georthocladius is represented in Europe by three species: G. collarti (Goetghebuer, 1941), G. luteicornis (Goethghebuer 1941) and G. retezatiAlbu, 1972. As many characters in these species are similar, they all should be treated as one and the same species. Differential diagnosis, comments on the ecology of the two new species and key to known male adults from Europe are given.
