Here we assess the role of weather conditions on the distribution and abundance of the enigmatic glossy ibis (Plegadis falcinellus) in Northeast Algeria in both wintering grounds and in breeding areas in a survey spanning from 2011 to 2019. During the study period, cooler years were wetter and warmer years were drier. The wintering population size in the region could be estimated to 200-300 individuals. The number of individuals in wintering grounds increased in recent years in one site (Berrihane), but it did not show a strong association with weather conditions prior to wintering. Four breeding colonies were detected in highly-vegetated ponds with in-water trees where the number of breeding pairs was the highest. Extinction was recorded for two colonies (50% of colonies) where one permanently disappeared and one exhibited a series of extinctions and recolonizations across years. The estimated colony size was larger at El Dakhla (60–105 pairs) than El Chatt (0–42 pairs), Fezara Lake (25–41 pairs), and Tonga Lake (0–2 pairs). Climate conditions seemed to correlate with the number of pairs in one site (El Chatt) such that warm and dry years were associated with lower number of individuals. We discuss that disturbance and pollution might play a role in colony establishment but the number of pairs is positively related to the extinction of a nearby colony, suggesting that those refuge colonies are crucial for the persistence of the species in the area. This study presents historical data on the occurrence and abundance of a relatively unstudied species and gives new information on its climatic sensitivity which might be helpful for predicting future climate change impacts.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"69 1","pages":"193 - 204"},"PeriodicalIF":0.5,"publicationDate":"2022-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45904073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Skinks were collected in savanna habitats in Namibia. In all these species, active foraging strategy predominates. All skink species preyed almost exclusively on insects. Four insect taxa comprised the bulk of diet in all five species investigated: Coleoptera, Orthoptera, Isoptera, Hymenoptera (Formicidae) and larvae. Their overall contribution ranged from 72.2% to 100.0% of all prey items in the diet of particular skink species. Most prey items were below 10 mm long, some were 11-20 mm in length. Both males and females fed on the same prey groups, but there were marked differences in the proportions of these groups. In general, males preyed more on beetles and grasshoppers, while females – more on ants. All main prey groups were recorded both in dry and in wet season in all five skink species. Food niche overlap was the highest between T. damarana and T. wahlbergii (0.84), and between T. binotata and T. punctulata (0.77).

Therefore, it is need to understand mechanisms that naturally increase the acquisition of nutrients by plants. Earthworms are crucial soil engineers that play a key role in soil functioning. In this study we have estimated the impact of three factors, earthworm species, ecological group, and soil type, on the ion content of casts of Eisenia nordenskioldi, E. ventripapillata, E. nana, Lumbricus rubellus, and Aporrectodea caliginosa. Laboratory experiments were performed in microcosms on three soil types. We analyzed five water-soluble cations and six anions in the earthworm casts by capillary zone electrophoresis to determine their content in casts compared to soil. For three of the five species studied this is the first information obtained on the matter. The obtained data demonstrated that soil type has the biggest impact on the observed changes in the cast ion content, probably due to the differences in the initial concentrations and soil properties. Within each soil type, the observed effects were mostly species-specific, and the species belonging to the same ecological group (endogeic and epi-endogeic) did not have similar effects. The exposure to different earthworm species resulted in pronounced differences in the concentrations of magnesium, calcium, ammonium, and chloride, while the soil type had the highest impact on sulfate, fluoride, acetate, and sodium ions. Therefore, the terms ‘ecological group’ and ‘functional group’ are not equivalent for earthworm casts, and replacing an earthworm species with another belonging to the same ecological group may result in changes of the soil ion composition.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"69 1","pages":"96 - 110"},"PeriodicalIF":0.5,"publicationDate":"2021-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41505578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the state of Chihuahua, Mexico, native grasslands have a great ecological importance due to their wide distribution; however, studies on the current and future potential distributions of grasslands, as well as their temporal dynamics based on climatic variability, are lacking. Thus, we analysed the potential distribution of five native grasses (Bouteloua curtipendula, Bouteloua gracilis, Leptochloa dubia, Digitaria californica and Setaria macrostachya) based on climatic factors. The present data of these species were consulted at the Global Biodiversity Information Facility (GBIF) and recorded with location information: latitude and longitude. This database was complemented with presence data of the five species from previous studies. To characterize the climate niche, the values of the climatic factors at the locations of the species presence, were obtained from the WorldClim. Then, current and future potential distributions of these native species, were generated based on three climate change scenarios, based on Representative Concentration Pathways - RCP2.6, RCP4.5 and RCP6.0). Under the RCP2.6 scenario, the estimated area of S. macrostachya was 12,525.5 ha, representing 7.4% of the state. For B. gracilis, the potential areas under the RCP4.5 and RCP6.0 scenarios were 20,391.49 and 23,079.08 ha, respectively. B. curtipendula represented the smallest area, with 4.6% under the scenario RCP2.6. The distribution of grassland species in northern Mexico is mainly determined by climatic factors; as it may apply for the rest of the grassland species within this area, so those results could increase our knowledge about their potential distribution.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"69 1","pages":"73 - 83"},"PeriodicalIF":0.5,"publicationDate":"2021-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45567621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2018 we found two unusually large clutches, one for each species (8 and 9 eggs, respectively), both containing two distinct egg morphs differing in coloration. Further detailed analysis of egg morphology and brood phenology (in the whitethroat) suggested that the eggs in each nest had been laid by different females. Surprisingly, two seemingly full sized clutches were laid in both nests, a pattern that is unusual in conspecific brood parasitism in passerines, whose nests are typically parasitized with single eggs. Alternatives to conspecific brood parasitism are therefore discussed. We argue that traditional field-based methods, when carefully used, may be sufficient to document brood parasitism recorded during occasional observations. We finally conclude that enlarged broods, resulting from conspecific brood parasitism, are probably more frequent than expected, but they may be often overlooked.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"69 1","pages":"124 - 133"},"PeriodicalIF":0.5,"publicationDate":"2021-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42457789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reveal the relationship between individual age and diameters at breast height (DBH) of D. involucrata，five populations were chosen in the largest distribution area of D. involucrata in Sichuan province. Dendrochronology and regression model was used to evaluate the distribution of the DBH and its relationship with the age, respectively. All 130 D. involucrata trees recorded in the studied plots, with the minimum DBH of 3.8 cm, and the maximum of 45.5 cm, corresponding to the minimum age of 4 years and the maximum age of 98 years. The results showed that in the first 11 DBH classes (DBH < 22 cm), the tree DBH increases relatively slowly with the growth of the age. After the 11th DBH class, the DBH class increases slowly with increasing tree age. The tree age exceeds 20 years, the increase in the DBH growth rates with tree age is similar among the five populations. The linear models were fitted to determine the regression equation for the DBH growth curve of D. involucrata, which can be well described by a parabolic model. Under normal forest stand development and growth conditions, the model can be widely applied to study the ages of individual D. involucrata.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"69 1","pages":"84 - 95"},"PeriodicalIF":0.5,"publicationDate":"2021-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42986789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three functional traits (leaf nitrogen content, LNC; specific leaf area, SLA; leaf dry matter content, LDMC) were measured and the community-level weighted means of the trait values were calculated by the species coverage values. Climate and terrain data were generated from the climate model ClimateAP and using ArcGIS. Finally, eight environmental factors, including climate, topographical, and soil factor, were recorded and the association with functional traits was analysed using a generalized additive model. Model testing indicated a good predictability for the SLA and LDMC while a relatively poor predictability was seen with LNC. Environmental factors that significantly impacted SLA included elevation, degree-days above 0°C, mean annual precipitation and total soil nitrogen content. In contrast, LDMC was significantly influenced by elevation, total soil nitrogen and phosphorous content while LNC was affected by elevation and degree-days above 0°C. High values of SLA and LNC were found in areas at lower elevations. The distribution of high LDMC values indicated that plant leaves have a relatively high tolerance and resistance to stress, which was better for plant to grow in the adverse environment. At the community level, clarifying plant functional traits distribution and their changes with environmental gradients is useful for the potential vegetation restoration.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"69 1","pages":"1 - 13"},"PeriodicalIF":0.5,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42417411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
