This systematic review of peer reviewed articles on attitudes towards gray wolves (Canis lupus), shows that attitudes are mainly measured either by mean values of attitudes or by proportional differences in attitudes. This may impact on how attitudes are perceived and interpreted across studies and areas. However, independent of method used, we found that people living in areas where wolves always have existed, are more negative towards wolves compared to people living in areas where there are no wolves, or where wolves have recovered after years of absence. People who express fear, or being directly affected by having wolves, such as farmers and hunters, report more negative attitudes compared to other groups of respondents. For wolf conservation we recommend politicians and management authorities to prepare local societies of the different consequences of living in wolf areas. We recommend using dialogues and conflict management methods to minimize the level of conflicts.

Communication between dogs and humans is a topic of growing interest, and the \"unsolvable task\" is a common method used to measure human-directed communication. In this task, dogs learn how to solve a problem to obtain a reward. After a fixed number of trials, the reward becomes impossible to access, arguably leading to communicative attempts from the dog. Although useful to observe dogs\' communicative behaviors in a fairly naturalistic situation, the methodology varies among studies regarding apparatus, number of trials, and other factors. The proxies used, for instance, gaze duration or frequency of gaze alternation, also vary, and there are discrepancies and a debate regarding what the task actually measures. Therefore, in this study, we reviewed the usage of the unsolvable task in canids of the genus Canis, searching Web of Science and Scopus for the terms \"dog*\", \"Canis\", \"dingo*\", \"wolf\" or \"wolves\" in the title and \"unsolvable task\" or \"impossible task\" in the topic. We included thirty-five studies in this review and discussed their different methodologies and proxies, such as different apparatuses, number of solvable trials, and different interpretations of \"looking back\", pointing out how they can affect results and hinder comparisons. Lastly, we used current data to propose strategies to homogenize the use of this important paradigm, with an ethogram of possible behaviors and their interpretation and a predefined set of methodological aspects for future research.

Fatalities due to animal attacks are rare in forensic medical work but have been known to pose problems due to their potential to mimic homicide. This review summarizes reported cases of fatal attacks by large mammals that inhabit the Nordic wilderness, namely brown bear, moose, wild boar, and wolf, and attempts to elucidate injury patterns that can guide the forensic pathologist to identifying the species and modus operandi of the attacker. A tendency toward a species-specific injury pattern was observed. Injuries by bear and especially wolf are dominated by biting whereas moose and wild boar do not seem to bite their victims. The bear uses its paws, both for hitting, resulting in crush injury and fractures, and clawing with resulting excoriations and possible penetrating injuries. Crush injuries and fractures appear, on the other hand, to be minimal or absent in attacks by wolf and wild boar.
