Amphibians are an ecologically diverse class with a wide range of social and sexual behaviours, making them a compelling model to understand the potential adaptations of animals faced with the effects of human-induced rapid environmental changes (HIREC). Poison frogs (Dendrobatoidea) are a particularly interesting system, as they display diverse social behaviours that are shaped by conspecific and environmental interactions, thus offering a tractable system to investigate how closely related species may respond to the impacts of HIREC. Here, we discuss the potential impacts of global change on poison frog behaviour, and the future challenges this group may face in response to such change. We pay special attention to parental care and territoriality, which are emblematic of this clade, and consider how different species may flexibly respond and adapt to increasingly frequent and diverse anthropogenic stress. More specifically, we hypothesise that some parents may increase care (i.e. clutch attendance and distance travelled for tadpole transport) in HIREC scenarios and that species with more generalist oviposition and tadpole deposition behaviours may fare more positively than their less flexible counterparts; we predict that the latter may either face increased competition for resources limited by HIREC or will be forced to adapt and expand their natural preferences. Likewise, we hypothesise that human-driven habitat alteration will disrupt the acoustic and visual communication systems due to increased noise pollution and/or changes in the surrounding light environment. We highlight the need for more empirical research combining behavioural ecology and conservation to better predict species’ vulnerability to global change and efficiently focus conservation efforts.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"26 3","pages":"151 - 166"},"PeriodicalIF":1.1,"publicationDate":"2022-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42237249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Behavioural observation methods used so far are insufficient to unravel if females form a cohesive “harem,” simultaneous polyandry (promiscuity) occurs in the wild, and multipaternity occurs in each clutch. We used molecular markers to conduct for the first time a genotype-based sibship and parentage assignment analysis among reproductive individuals and their offspring, within and between nests, in a wild Greater Rhea population of central Argentina. In a 4800-ha area, we found five nests from which we collected complete clutches and feathers of incubating males. We successfully determined the genotypes of three males and all 141 offspring at 8 microsatellite loci. We inferred the parents involved in matings and their genotypes based on offspring’s genotypes. A total of 37 males and 47 females were engaged in the assigned pairings, and one incubating male did not fertilise any egg. We obtained three main novel results that enlighten the mating system of Rheas: (a) females do not form “harems”; (b) there is evidence of promiscuity; and (c) incubator male does not father the majority of offspring from his nest. The strategy of Greater Rheas is to copulate with several individuals simultaneously and lay eggs in different nests, independently of whether or not the incubating male fathers those eggs. These results provide a new and significant step in understanding the complex mating system of this ratite.\u0000</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"25 3","pages":"155 - 164"},"PeriodicalIF":1.1,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48201811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we use sightings data from research platforms and whale watching tours in six regions of Iceland from 2007 to 2020 to show that the occurrence of long-finned pilot and killer whales varied with region and season. Killer whales were regularly encountered in the south of Iceland during summer and west of Iceland during winter/spring. Long-finned pilot whales were only seen during the summer and were most often encountered in the south, west, and northwest of Iceland. Long-finned pilot whale occurrence in the south of Iceland appeared to increase during the study period but killer whale occurrence showed no noticeable changes. Long-finned pilot whales were sighted often in the areas that were also frequented by killer whales and interspecific interactions were commonly observed when both species co-occurred. Interactions appeared to be antagonistic, with killer whales often avoiding long-finned pilot whales and sometimes fleeing at high speed, similar to what has been described elsewhere in the North Atlantic. In the majority of interactions observed (68%), killer whales avoided long-finned pilot whales by moving away, but in 28% avoidance was at high speed with both species porpoising. This variability in the type of behavioural responses indicates that interactions may be more complex than previously described. We discuss regional trends in long-finned pilot whale and killer whale sightings and potential drivers of the observed interactions.\u0000</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"25 3","pages":"141 - 154"},"PeriodicalIF":1.1,"publicationDate":"2022-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10211-022-00394-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48157516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The following animal activities were observed: environmetal exploration, movement, swimming, stationary, grooming, play, flee, feeding, change of environment, mating behaviour and territorial marking. In case of the coypu, crepuscular and nocturnal activities were prevalent. Activity during daytime occurred mostly during winter days with low temperatures. On the other hand, American minks were mostly diurnal. The shift in behaviour compared to American minks in their native environment could be a sign of its adaptation to a new environment.

Mongooses are known to consume crabs (<i>Brachyura</i>), insects, and some small reptiles. However, this article presents the first record case of mongooses using stone anvil to crack open land hermit crabs. From our observations and field records, we determined that mongooses use flat rocks as anvils and their front paws to tap hermit crabs’ shells repeatedly to break the shells and remove the hermit crabs. We also observed that the mongooses only ate the abdomens of large hermit crabs. Additional studies are necessary to determine why the mongooses migrated to the coastal forest and how they learned to open hermit crab shells.

Our results indicate that scorpions from the Atlantic Forest tended to use their stinger more frequently than those from the Caatinga habitat. We also found that Caatinga scorpions moved approximately 40% more after prey capture than the Atlantic Forest species. Environmental pressures related to the metabolic costs of venom production and potential predation risk may partially explain the differential behavior observed in this study.
