P resorption efficiency (53.87%) and seasonal lignin change (69.87) were higher on the southern slope. As a result, the slope aspect affects the foliar N, P, and lignin concentrations. Also, foliar lignin concentration was negatively correlated with N resorption efficiency and positively correlated with P resorption efficiency.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"70 1","pages":"89 - 102"},"PeriodicalIF":0.5,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46146885","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}

The results showed that the total number of nematodes in most of the film mulched (FM) fields was lower than in no film mulched (nFM) fields. Most of soil chemical properties showed no significant difference between nFM samples and FM samples. Only 0–10 cm soil layer in nFM samples had significantly higher urease activity than in FM samples in June. Plastic film mulching may have an adverse effect on soil quality.

Species of the Lasius subgenus Chthonolasius Ruzs., which live cryptically underground, have not been considered regular mutualists of those aphids. They often nest close to the known mutualists with which they are through their mutual colony developments intimately interrelated – as temporary social parasites of L. brunneus or temporary hosts of L. fuliginosus. Such a constellation raises the question about contacts of L. (Chthonolasius) species with Stomaphis aphids. Here, we describe modes of interaction between L. (Chthonolasius) umbratus (Nyl.) and S. graffii Cholod. which is usually hosted by L. (L.) brunneus. Our field data from Poland and elsewhere in Europe, together with published information, support our view that also L. (Ch.) umbratus and other underground-living species of the subgenus Chthonolasius are true mutualists of Stomaphis which take care of the aphids. Such ants differ by their protective behaviour from ants which prey on or only exploit aphids. The co-occurrence of L. (Chthonolasius) species with Stomaphis aphids has hitherto been relatively rarely reported, which probably is due to the cryptic lifestyle of these ants. We discuss the complex interrelations among the above Lasius F. species which belong to separate levels of social parasitism, and their relations with Stomaphis aphids. We also suggest that L. (Chthonolasius) species, which in the socially-parasitic hierarchy are located between Lasius s. str. and L. (Dendrolasius), may serve as transmitters of Stomaphis aphids from the former to the latter species.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"70 1","pages":"44 - 55"},"PeriodicalIF":0.5,"publicationDate":"2022-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46362533","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}

This study is an updated review of the allometric equations, biomass allocation data and productivity estimations in Pinus massoniana forests of China published in articles during the period from 1982 to 2019. Different allometric equations of Pinus massoniana showed site-specific dependences. The aboveground and total tree biomass were expressed as power equations of mean age for Pinus massoniana forests. The mean value of aboveground tree biomass, total tree biomass and ecosystem biomass across all ages for Masson pine forests was 109.81, 127.65 and 138.76 Mg/ha, respectively. The mean proportion of stem, branch and foliage to aboveground tree biomass for Pinus massoniana was 77.1%, 15.9% and 7%, respectively. The tree root biomass continuously increased with the aboveground tree biomass and a power relationship was found between the tree root biomass and aboveground tree biomass for Pinus massoniana forests. The tree net primary productivity increased with aboveground tree biomass for Pinus massoniana forests, and the relationship was expressed as a linear equation. The mean tree, litter and ecosystem net primary productivity was 7.04, 4.88 and 8.30 Mg/ha/year, respectively.

Thus, the presence of feral dogs in nature reserves poses a major problem for wildlife conservation. In this study, we recorded the effects of free-roaming dogs (Canis familiaris) on wildlife species in a protected Mediterranean forest reserve in southern Turkey. By using camera traps and line transects we sought to understand how the presence of feral dogs impacted the main wildlife species in the study area. Applying presence-absence transect surveys and camera trapping techniques to estimate animal occurrence we covered approximately 97,00 ha and recorded 4209 images over a 154-week period. We found that the presence of feral dogs was significantly correlated with the movement of frequently observed wildlife species. Based on transect surveys, the species significantly affected by dog presence were fallow deer (Dama dama), wild boar (Sus scrofa), beech marten (Martes foina), badger (Meles meles), and red fox (Vulpes vulpes). Based on the camera trap data, fallow deer were negatively affected and wild boar not affected by dog occurrence while wild goat (Capra aegagrus) and caracal (Caracal caracal) were positively affected. The occurrence of wild boars, wild goats, hares, beech martens, red foxes and caracals across our study area increased with distance from agricultural land, while the occurrence of deer decreased. Overall, our findings suggest that the presence of dogs has a strong influence on wildlife in our study reserve. Since protected areas often are a final refuge for many of the species observed in this study, there is a need to take urgent measures to prevent feral dog impacts on wildlife and to reduce feral dog populations in wildlife reserves.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"70 1","pages":"56 - 67"},"PeriodicalIF":0.5,"publicationDate":"2022-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45437504","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}

However, both environmental and ontogenic factors may influence leaf size and/or shape, which may alter the coefficient of LA models. We carried an investigation along an altitudinal gradient in the Sergyemla Mountains, southeast Tibet. In August 2009, we selected nine sites at about every 50 m in altitude from 4,250 m to 4,640 m a.s.l. A total of 4,245 different leaf-aged Rhododendron aganniphum var. schizopeplum (a dominant overstory species) leaves were measured. Compared with the single dimensional models, the two-dimensional model encompassing both L and W (model 5) reflected higher R2 (0.98–0.99) and lower MSE (1.19–3.21) across different leaf age groups for each site, implying that such model could provide the best fit for LA estimation. Analysis of covariance further illustrated that two leaf dimensions model was irrespective of leaf age effects in eight out of the nine sites. Leaf shape (L:W ratio) varied between sites and tended to decrease at higher altitudes (4500–4640 m a.s.l.), leading to significant differences in coefficients of the two-dimension model between every two adjacent sites. For overstory species in alpine habitats, altitude rather than leaf age may affect leaf shape which alters the coefficients of LA estimation models. Since leaf shape of different species (overstory species versus understory ones) may show different responses to a certain environmental gradient, researchers must pay attention to the variation of leaf shape when estimating species-specific LA by measuring L and W, especially when leaves of the top overstory species were collected at different sites.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"70 1","pages":"33 - 43"},"PeriodicalIF":0.5,"publicationDate":"2022-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46487076","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}

We used UV light traps at one burned site and two neighboring unburned sites with a similar character as the burned site before the fire event. We analyzed moth assemblages using several species diversity indices – index of dominance, Shannon-Wiener index and Shannon-Wiener evenness, Simpson index, and Chao1 nonparametric estimation. We detected 67 species at the burned site, and 97 and 106 at the unburned sites. The three most frequently trapped species at all sites were Macaria liturata, Buphalus piniaria and Thera obeliscata, representing common forest geometrid moths. We observed a decline in species number and abundance at the burned site compared to the unburned sites, probably due to the direct mortality of larvae. On the contrary, the burned site was more diverse according to the diversity indices. The fire disrupted the original character of the coniferous forest, which was proved by a decline of species feeding on conifers and Vaccinium spp. The burned site attracted species associated with dry habitats such as Eublemma purpurina, Charissa obscurata and Scopula rubiginata. Even though wildfires are viewed negatively in general, they might temporarily enhance diversity in a homogeneous landscape.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"69 1","pages":"156 - 171"},"PeriodicalIF":0.5,"publicationDate":"2022-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47828673","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 this field study, the carbon storage in overstory, understory, litter layer of plants and soil carbon in forests was investigated in 26-28 year-old Masson pine (Pinus massoniana) pure and mixed forests along a latitudinal gradient (20–30 °N) crossing Hunan and Guangxi provinces of China, during the period of May 2015–August 2017. We found that the total carbon storage in Masson pine forests ranged 88.92–149.41 Mg/ha, of which 54.03% occurred in aboveground compound and 45.97% occurred belowground. The overall total carbon storage distribution was 34.62–68.72 Mg/ha, 3.82–10.19 Mg/ha, 2.37–3.96 Mg/ha, and 6.06–12.08 Mg/ha in stems, branches, leaves, and roots, respectively. The carbon storage in the overstory of forest stands and forest soils significantly decreased with increasing latitude, while the carbon storage in the understory and litter of the forest stands significantly increased as the latitude increased. The overall carbon storage significantly decreases by 8.26 Mg/ha in Masson pine forests as the latitude increased by one degree. The carbon storage increased by 8.43% in Masson pine mixed forests compared to the pure forest stands after the transformation from the pure forest stands into the mixed forest stands ∼ 15 years later. The results of changes in carbon storage in the studied forests with the latitudinal gradient could be attributed to variations in hydrothermal conditions with changing latitudes. The forest structure with different tree species composition was another important factor regulating carbon storage in forest ecosystems at the same latitude. The results provided a scientific basis for better understanding of latitudinal variation and spatial distribution of carbon storage in Masson pine forest stands with optimal forest stand structures in subtropical region of China.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"69 1","pages":"137 - 155"},"PeriodicalIF":0.5,"publicationDate":"2022-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47568521","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}
