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}

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.

Observational data were collected during two consecutive 5-day periods: control and treatment. Scan samples within a 2-h observational session were carried out, recording capybara incursions into a 15 m × 15 m marked perimeter and alertness behavioral state. During the treatment period, 30 g of jaguar feces were added daily every 5.0 m around the perimeter in four selected areas (around Lake Paranoa, Brasilia, Brazil) frequented by capybara. The presence of predator feces induced changes in capybaras’ behavior as there was a decrease in actual presence at the sites as a whole with the presence of jaguar feces. Of those capybaras that did continue to visit a site, incursions into the marked perimeter were initially greatly reduced, but did rebound relatively rapidly over the trial period. Although our results showed that capybaras recognize jaguar’s feces as a predator threat, odor habituation may limit the repellent’s efficacy at a local level, but appeared to have a longer term effect on the overall numbers of capybara visiting a site in general. Improvements in this technique will be required for it to become practicable, to reinforce capybaras’ aversion to predators, to decrease their habituation to predator’s feces, and to provide more humanitarian control.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"24 3","pages":"205 - 216"},"PeriodicalIF":1.1,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s10211-021-00377-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41953389","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}

It is an opportunistic breeder, adapted to transient breeding opportunities in its native sub-Saharan African range, which is often climatically unpredictable. The least equatorial range of invasive waxbills is now in Europe, in the Iberian Peninsula, where they experience predictably seasonal climate. Previous reports of waxbill breeding phenology in two different regions in Iberia show a very long breeding season, but differ in whether or not peak breeding coincides with the Spring breeding of native passerines. Using field data from over 20 sites across climatically different regions in their Iberian range, we show that waxbills have a long breeding season extending until Autumn, but with a clear Spring peak around May, both in regions with hotter and milder summers. Nest monitoring in a large mesocosm with over 50 waxbills, across 3 years, confirmed these field observations and showed what appears to be year-to-year plasticity in phenology, which may include smaller nesting peaks outside Spring. This behavioural flexibility, together with the long breeding season of waxbills in the Iberian temperate climate, likely facilitates their invasion success.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"24 3","pages":"197 - 203"},"PeriodicalIF":1.1,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s10211-021-00376-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45171332","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}

But knowledge about the potential influence of human presence on social associations and interactions is rare, albeit differences may result in changing impacts on the environment, such as habitat utilization and feeding damage. Therefore, we investigated differences in the space use and social association of red deer. We studied two radio-collared herds of non-migratory populations in two study areas, which were comparable in landscape structure and vegetation structure, but differed in accessibility for visitors and the extent of their presence. Between the two study sites we compared the home range size, the differences in the extent of home range overlap within each study site and the space–time association (Jacobs Index) of individuals. Additionally, we present data on seasonal variations of home range sizes and social association all year round. In order to compare human activity in the study sites, we used the data from our long-term camera trap monitoring. The herd in the area with more human activity had significantly smaller home ranges and had greater year-round social associations in almost all seasons, except summer. We assume that smaller home ranges and higher association between animals may result in a higher feeding pressure on plants and a patchier utilization in areas with higher disturbances.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"24 3","pages":"185 - 195"},"PeriodicalIF":1.1,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s10211-021-00375-w","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43858927","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}
