The reptile species assessed by IUCN are only a fraction of those at risk of extinction. Thus, conservation planning and management decisions are hindered by the lack of ecological information on the species' distribution patterns and their habitat requirements. Pleske's racerunner (Eremias pleskei) is a rare and critically endangered species known to occur exclusively in the eastern Anatolian Montane Steppe ecoregion. In this study, we used ten species distribution model algorithms and 62 climate change scenarios (from 19 global climate models under four representative concentration pathways) to predict future habitat suitability for Pleske's racerunner in the Anatolian Montane Steppe ecoregion. Our results indicate that this species may in future migrate from its current distribution range towards the central and western areas of the Anatolian Montane Steppe ecoregion. Our results also show that the variation in the temperature-related variables in suitable habitats will increase in future as compared with the current conditions. It seems that due to climate change, in future, deserts will be appropriate for this species. The same mechanisms, however, will make some of its current habitats unsuitable. Dealing with uncertainties in climate change and species distribution modeling is a major challenge when planning strategies for species' conservation. We recommend conservation measures to be implemented to make sure that E. pleskei's current habitats remain suitable for it also in future.","PeriodicalId":50968,"journal":{"name":"Annales Zoologici Fennici","volume":"56 1","pages":"106 - 93"},"PeriodicalIF":0.7,"publicationDate":"2019-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41458291","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}

However, there is little information on the ability of individuals to change their feeding strategy in time because most studies do not evaluate prey availability and its effect on individual behaviour. To better understand how variation in prey availability may affect the feeding strategy of newts, we studied the Alpine newt, Ichthyosaura alpestris, during April and June in 2015, when we monitored prey availability and the species dietary habits. In April at low prey diversity, the newts were generalists, i.e., their diet overlapped almost completely with prey availability. In June when prey diversity was high, the newts became specialists. At the individual level, 9 out of 15 recaptured newts shifted from a generalist to a specialist feeding strategy from April to June, suggesting a rapid behavioural change in response to increasing prey diversity, in accordance with optimal foraging theory. These results stress the importance of sampling the same individuals several times during an extended period of time to better understand the patterns of diet variation in amphibians.","PeriodicalId":50968,"journal":{"name":"Annales Zoologici Fennici","volume":"56 1","pages":"17 - 24"},"PeriodicalIF":0.7,"publicationDate":"2019-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49427685","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}

During four consecutive years (2009–2013), we determined territory size of the serra antwren, a highly territorial bird, that occupies permanent territories in the restinga habitat. We studied seasonal variation and relationship between territory size, number of neighboring territories and floaters (mature individuals without fixed territories), and body size of the territory holders. We also estimated population density using a capture–recapture method. Territory size was smaller during the breeding season with its size affected by number of neighboring territory holders and year. Densities were estimated to be 1.6–5.8 indiv. ha–1, which were 2 to 6 times higher than the value previously estimated by fixed-radius point counts (0.93 indiv. ha–1). This may be due to the high number of floaters, potentially important but usually neglected in density estimates. Neighboring territory holders affected more than floaters territory size, possibly because of their similar individual qualities.","PeriodicalId":50968,"journal":{"name":"Annales Zoologici Fennici","volume":"56 1","pages":"51 - 64"},"PeriodicalIF":0.7,"publicationDate":"2019-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43638460","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}

For the pine marten (Martes martes), rodents such as bank voles are the primary prey; however, the pine marten can switch to a variety of secondary prey items (e.g., birds, fruit and frogs) when the rodent abundance is low. We measured frog ilia found in pine marten scats during several consecutive years to assess whether the body mass of consumed frogs varied with changes in rodent abundance. Rodent density was inversely related to the frequency of occurrence of frogs in the marten's diet. Moreover, during the years with low rodent abundance, pine martens ate smaller frogs than in the years with high rodent availability. The average frog weight (18 g) during the years with high rodent density was similar to average vole weight, suggesting that prey of this size has an optimal ratio of foraging effort to energetic gain. During the lean years, martens preyed on frogs smaller than the average vole weight, and during spring this frog size-group is usually the most abundant in the environment. Our results suggest that functional responses of predators to low abundance of primary prey involve not only a prey-switch but also a decrease in the size of secondary prey consumed. Fluctuations in the proportion of frogs eaten in relation to yearly rodent density can affect both marten and frog population demography.","PeriodicalId":50968,"journal":{"name":"Annales Zoologici Fennici","volume":"56 1","pages":"41 - 49"},"PeriodicalIF":0.7,"publicationDate":"2019-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46631065","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 research was based on 239 ring recoveries during non-breeding periods from 92 ringing sites in Poland. We used location of ringing sites, age of bird, and year of recapture to explain variation in the observed distances between breeding and stop-over as well as wintering areas. We found variation in the location of non-breeding areas of grey herons from northern and southern Poland. Migration distance of grey herons increased with latitude, with birds from northern Poland spending the non-breeding period further away than birds from southern Poland. Considering possible shortening of the migration distance due to climate change, we analysed frequency of recoveries from the vicinity of the breeding site, Mediterranean and sub-Saharan zones. Despite reported claims of climate change leading to migration distance becoming shorter, we found that distance to those areas was not affected significantly by year. In contrast to previous studies made in western Europe, age of bird did not affect migration distance.","PeriodicalId":50968,"journal":{"name":"Annales Zoologici Fennici","volume":"55 1","pages":"277 - 285"},"PeriodicalIF":0.7,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5735/086.055.0601","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43469642","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}
