Barnaby & Grimes is an important species for forest plantation programmes in Malaysia and is widely used in the wood industry. However, its root interactions have not been widely investigated due to the limited methodologies and information about the root distribution of trees and crops in forest plantation and agroforestry systems. This study was conducted to determine the rhizotron-scale root interactions of F. moluccana at different tillage and nitrogen concentrations under four different treatments: control, tillage, fertiliser, and tillage with fertiliser. The rhizotron-scale experiment was conducted at a greenhouse where F. moluccana (Batai) seedlings were transplanted in transparent rhizotron tubes (onemetre-high transparent polycarbonate solid sheet) using topsoil and river sand to simulate natural growing conditions. Root Intensity (RI), Root Length Density (RLD), Specific Root Length (SRL), dried shoot bio-mass and root biomass were recorded. Root biomass and SRL were notably higher (25–50 cm depth) at 6 WAT (Weeks After Transplanting), and the shoot biomass (tillage + fertiliser) was significantly higher at 14 WAT. However, plants treated with different tillage and nitrogen concentrations showed no significant impact on the RI and RLD. Fertiliser treatment only, and tillage with fertiliser treatment, showed greater root distribution at the rhizotron scale. These findings contribute to forest plantation and natural forest rehabilitation efforts by helping optimise the soil resources within ecosystems for sustainable forest management.","PeriodicalId":52505,"journal":{"name":"Folia Oecologica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139635649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the effects of stand types on litterfall, litter decomposition, and forest C storage in Pinus densiflora S. et Z. and Quercus variabilis Blume stands in southern Korea. The aboveground C storage by tree biomass was not affected (P > 0.05) by stand types (P. densiflora: 79.49 Mg C ha–1; Q. variabilis: 96.37 Mg C ha–1). However, total C inputs by litterfall were significantly higher for the P. densiflora (4,473 kg C ha–1 year–1) than for the Q. variabilis (2,633 kg C ha–1 year–1) stands. Organic C over litter decomposition processes was more rapidly mineralized in the leaf litter of Q. variabilis than in needle litter of P. densiflora, but C storage on the forest floor was not affected by different stand types. Total soil C storage was not significantly different between the Q. variabilis (55.71 Mg C ha–1) and P. densiflora (80.49 Mg C ha–1), whereas the C concentrations at each soil depth were significantly higher in the P. densiflora than in the Q. variabilis stands, except for the subsurface depth (30–50 cm). These results indicate that the distribution of C storage in P. densiflora and Q. variabilis stands is less susceptible to interspecific differences, such as litterfall inputs and decomposition rates.","PeriodicalId":52505,"journal":{"name":"Folia Oecologica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139636893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also evaluated the level of knowledge of operators about these threats. Experts identified five priority target-specific threats: Roads and Railroads; Invasive-Non Native/Alien species; Other Ecosystem modifications; Recreational Activities, and Storms and Flooding. Storms and Flooding and Invasive-Non Native/Alien species appeared the threats with significant highest magnitude. Knowledge of threats is comparable without significant difference among them. However, Storms and Flooding and Roads and Railroads are the threats having both the highest level of knowledge by experts and the highest magnitude. At the opposite, Mowing was the less known threat regarding its regime and showed the lowest magnitude.

This research was motivated by strong invasive trends, risks for native vegetation and a lack of data on giant hogweeds in Ukraine. We presented phytosociological tables of giant hogweeds communities, maps of their modern distribution in Ukraine, a dendrogram of similarity of the communities, phytoindicative evaluation, and proportions of diagnostic species in the syntaxa. According to our survey and literature data, there are 102 locations of H. mantegazzianum and 405 locations of H. sosnowskyi throughout most of Ukraine, except for the steppe zone, where the limiting factor is the arid climate. The amplitudes of both studied Heracleum species have a significant overlap in the factors of humidity, nitrogen, and salt regime. There are differences between the species in the factors of light, temperature and continentality. The amplitudes of the studied species are the widest for moisture and the narrowest range for soil acidity. Both species favour soils enriched in nitrogen. Based on the phytosociological survey, the species forms two distinct associations Urtico dioicae-Heracleetum sosnowskyi and Urtico dioicae-Heracleetum mantegazzianii and also occurs with lower abundance in communities belonging to 8 vegetation classes. The obtained data can be used to carry out preventive measures against the further spread of giant hogweeds in new habitats with varying degrees of anthropogenic transformation.","PeriodicalId":52505,"journal":{"name":"Folia Oecologica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139634542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used light and electron microscopy to determine the form and position of the stomata in relation to the leaf epidermal cells. The length, width, shape, area, perimeter, and stomatal density were all measured. Our findings revealed that the stomata type of A. negundo varengiayum, A. campestre, A. hyrcanum, A. mazandaranicum and A. monsspesulanum is anomocytic, A. platanoides and A. cappadocicum have anomocytic stomata with wavy subsidiary cells, while A. palmatum has anisocytic stomata and A. velutinum has parasitic stomata. A. negundo has actinocytic stomata. Regarding the location of stomata relative to adjacent epidermal cells, we identified three types. In the first type, the stomata were flush with adjacent epidermal cells (A. cappadocicum, A. negundo, A. platanoides). In the second type, the stomata were higher (A. negundo variegatum), and in the third type, the stomata were lower (A. velutinum, A. monspesulanom, A. campestre, A. mazandaranicum, A. hyrcanum). The principal component analysis was used to determine the essential stomatal traits in differentiating between species. We also investigated the distribution of trees in the coordinate axis space based on two main components and performed cluster analysis based on stomatal characteristics. A. platanoides, A. negundo, A. negundo variegatum were in one cluster, while the other species were in separate clusters. The calculation of dissimilarity among the studied species revealed the lowest similarity between A. negundo and A. hyrcanum and the highest similarity between A. campestre and A. mazandaranicum. The results of the discriminant analysis identified stomatal density as the essential factor in differentiation between the studied species.","PeriodicalId":52505,"journal":{"name":"Folia Oecologica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139633715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is known to weave its nests from leaf strips from a variety of tree species (mainly coconuts trees, oil palm trees) associated with human settlement areas, grasses, and other available plants. In this regard, this bird was considered a pest for its impact on different economic activities. Although extensive literature is already available on the parasitic role of village weavers, there is still a lack of analytical data that outlines which tree species are used for nesting and in what proportion, as well as the related implications in terms of economic impacts. Here, we carried out the first comprehensive arrangement of trees used by this species for nesting in Southern Nigeria (West Africa), checking for possible different impacts on stakeholders. In April 2021, we searched for village weaver nesting in 95 sites in 77 communities from 24 local government areas in Southern Nigeria, during 14 field surveys. Within each site, we collected GPS coordinates and counted the number of active nests, nesting birds and occupied trees. We recorded a total of 5,776 nests and 2,140 birds in 94 plants belonging to 23 tree species selected for nesting. Oil palm (Elaeis guineensis; n = 45) was the most used tree species, as 2,990 (51.77%) nests and 873 (40.79%) birds were recorded.

The medium supplemented with 4.0 mg l−1 DIC in combination with 1.0 g l−1 CH gave the highest callus weight (287 mg), while the maximum response rate and the number of shoots per jar (86.67% and 15.07 shoots/jar) were found in MS media equipped with 4 mg l−1 DIC and 0.5 mg l−1 CH combination. The total amount of phenolic compounds was significantly reduced to 0.82 and 0.79 mg GAE g–1 in shoots cultured in the medium equipped with 4.0 mg l−1 DIC with 0.5 and 1.0 g l−1 CH, which is reflected in the rate of browning. The results showed that the highest shoots content of endogenous IAA (3.71 and 3.50 μg g−1), were obtained in response to 4 mg l−1 DIC + 1.0 g l−1 CH and 4.0 mg l−1 DIC + 0.5 g l−1 CH, respectively.

The objective of this paper was to analyze the changes of litter mixture effects on decomposition between different soil fauna treatments (macrofauna inclusion vs macrofauna exclusion) and successional stages (mature forests vs secondary forests) in upper Andean tropical forests along time by using a reciprocal translocation experiment of 1,344 litterbags that ran for 18 months with six common native Andean species. Thought t-tests, linear regressions, and linear mixed models, I found that litter mixture effects vary among sites and increase with time in secondary forests until the year of decomposition in litterbags with macrofauna exclusion. Mature forests exhibited strong antagonistic effects, while pronounced synergistic effects were observed in secondary forests. Although soil macrofauna did not increase significantly litter decomposition and synergistic effects in the mixtures at any of the stages of decay, it is likely that soil macrofauna may impact litter mixtures through top-down effects within soil food webs, rather than exerting a direct effect in the litter consumption as has been reported in tropical lowland ecosystems. Overall, this study supports the idea that litter mixtures exhibit significant variability across sites, can change with successional stage, and are influenced by soil fauna depending on the stage of decay in tropical Andean montane forests.","PeriodicalId":52505,"journal":{"name":"Folia Oecologica","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139639133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
