Most available studies have examined behavioral traits which favor invasive species on the later stages of invasion, however, our knowledge on earlier stages, namely, when alien species face novel environments and must exploit new resources, remains obscure. Here, we focus on one crucial behavioral trait, finding food. The Italian wall lizard (<i>Podarcis siculus</i>) has been widely introduced and established viable populations in S. Europe and N. America. We examined whether <i>P. siculus</i> has enhanced exploratory behavior and abilities to find food compared to two native congeneric species with which it may come in contact in the near future, an insular endemic (<i>P. milensis</i>) and a widely distributed lizard (<i>P. erhardii</i>). We performed a Y-maze experiment, in which we varied arm markings in a standard way to prevent learning. <i>Podarcis siculus</i> was more efficient than its congenerics in finding and consuming food. This exploitative superiority was persistent, more frequent and repetitive. Interesting behavioral differences were also detected within the native species. Some <i>P. milensis</i> individuals showed no interest in exploring the maze, while few <i>P. erhardii</i> individuals remained rather indifferent to food even after detecting it. Our results suggest that the invasive <i>P. siculus</i> displays behavioral traits that could provide better opportunities for survival in the new environment and thus facilitate establishment even in the presence of congenerics. This provides further support to the idea that behavior plays a crucial role in animal invasions.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"25 1","pages":"43 - 55"},"PeriodicalIF":1.1,"publicationDate":"2021-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10211-021-00385-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50011742","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}

However, system perturbations, such as the removal of individuals, may cause instability, which varies according to the group’s resilience. If the hierarchy undergoes a restructuring, this can occur through a dynamic process of self-organization (Social Dynamics hypothesis) or through the influence of individuals’ attributes (Previous Attributes hypothesis). We analyzed the resilience of the white-lipped peccary hierarchy after the alpha’s death and observed how the rise of a new dominant occurred. Additionally, we evaluated the validity of these two hypotheses in the restructuring of the system. We observed the group of white-lipped peccary males of the Municipal Zoo of Curitiba, PR, Brazil, from May to October 2018. We recorded and analyzed the agonistic and affiliative interactions, and we collected data from the attributes: weight, testicle size, testosterone serum and age, before and after the dominant’s death (August). Due to this perturbation, the hierarchy started to show instability, but proved to be resilient. There was an increase in agonism and more than one individual pleading for the new dominant position, which was occupied by a subordinate male. Affiliative interactions were also important in the rise of the new alpha. The hierarchy was well ordered by the social dynamics among individuals, but weight and testicular volume were also correlated with the status of the individuals before, and with the serum testosterone after the alpha’s death. Thus, both hypotheses affected the restructuring of this system.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"25 2","pages":"65 - 77"},"PeriodicalIF":1.1,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45462405","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}

Nonetheless, the strategies employed by floral visitors to collect floral resources are extremely complex, and commonly involve theft or robbery in addition to pollination. We describe here the behavioral repertory of <i>Apis mellifera</i> during the collection of the floral resources, and evaluated the robbing rates of <i>A. mellifera</i> on the buds and flowers of <i>Pyrostegia venusta</i> during periods of intense and sparse flowering. We recorded the behaviors exhibited by foraging bees while collecting floral resources, quantified the numbers of floral buds and flowers with perforations in their corolla tissues, and determined whether that damage reduced nectar production. The evaluations were conducted during two distinct periods: during the period of intense flowering of <i>P. venusta</i>, and during the period of sparse flowering. Nectar robbing was observed during 93.4% of the visits of foraging <i>A. mellifera</i> bees, while nectar theft was observed during only 0.7% of the visits, and pollen theft during 5.9%. The robbing of floral buds and flowers was most intense during the period of heavy flowering. Flowers that had been intensely robbed secreted significantly less nectar than those non-robbed. The unusual nectar robbing activities of <i>A. mellifera</i>, especially during the period of intense flowering indicates an optimization of access to larger volumes of food resources. Our results therefore point to a major limitation of nectar per floral unit during the intense flowering period of <i>P. venusta</i> due to the high activity of nectar robbing by <i>A. mellifera</i> bees.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"25 1","pages":"25 - 32"},"PeriodicalIF":1.1,"publicationDate":"2021-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s10211-021-00383-w","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50102266","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}

The most studied species were greater and American flamingos, but there is a recent rise in studies on Chilean and Andean flamingos in Latin America. Most ethological studies on this group included quantitative analyses, ignoring a more qualitative perspective of the individuals’ displays. Behavior description can also help in comparative studies between flamingo species and other water birds. Expanding research to Andean, James’s, and lesser flamingos is a priority, since their populations are more vulnerable.

While it is known that some species adjust acoustic signals to communicate more effectively in noisy habitats, we know very little about how the receivers of these signals might be impacted by anthropogenic noise. Here, we investigated female and male <i>Litoria fallax</i> frogs’ ability to distinguish between high- and low-quality acoustic signals during the presence of background traffic noise and without. We performed a controlled behavioural experiment whereby frogs were presented with simultaneously broadcasted attractive and unattractive calls from opposing directions, once with background traffic noise and once without. We found that females in particular chose the unattractive call significantly more often (and males significantly less often) when noise was being broadcast. This indicates that anthropogenic noise potentially affects receiver responses to acoustic signals, even when calls are not acoustically masked, with potential consequences for maladaptive mating behaviours and population outcomes.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"24 3","pages":"217 - 226"},"PeriodicalIF":1.1,"publicationDate":"2021-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s10211-021-00378-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50007822","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}
