If properly managed, these open spaces allow structurally diverse vegetation to grow at the road-verges, which may support greater invertebrate abundance and species richness, increasing overall forest biodiversity. We investigated spider diversity along road edges in young plantation forests in Ireland, the influence of road-verge vegetation and the consequences of doubling the standard forest road-width currently used in Ireland. Active ground-dwelling spiders were studied in eight Sitka spruce (Picea sitchensis) plantations using pitfall trapping one year after planting and five years after planting. A total of 16,741 spiders were caught, from which 141 species were identified from 14 families. Ten spider species of conservation importance were found in the road-verges demonstrating their importance as habitats for spider diversity. We found no difference in ground-dwelling spider diversity between road-verge and forest interior plots at this stage in the rotation. We found no advantage or disadvantage of increasing the road-width of forest roads for ground-dwelling spider diversity of young plantation forests. The findings of this study are discussed in the context of the management of plantation forests for biodiversity conservation and associated forest policy development.","PeriodicalId":55370,"journal":{"name":"Biology and Environment-Proceedings of the Royal Irish Academy","volume":"os-27 1","pages":"259 - 271"},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87210169","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}

Spider wasps (Hymenoptera: Pompilidae) are a globally diverse family of solitary wasps that prey exclusively upon spiders. Most species provision nests with a paralysed spider, which serves as the sole food source for developing larvae. Adults are mostly nectar-feeders and many species may contribute to pollination. Here we present the first complete catalogue of the spider wasps of Ireland, the recorded distribution and temporal activity of each species, and short accounts of other aspects of the ecology of Irish Pompilidae. Irish spider wasp records were collated from voucher specimens held by the National Museum of Ireland, published literature sources and records provided by the National Biodiversity Data Centre (ROI), CEDaR and the National Biodiversity Network (NBN) Atlas (NI) to produce maps of the known distribution of each species. Ireland is home to thirteen confirmed Pompilidae species that may be considered native, and an additional species for which the Irish status remains unconfirmed until further specimens can be collected. Brief accounts of the ecology and behaviour of each Irish species are provided.","PeriodicalId":55370,"journal":{"name":"Biology and Environment-Proceedings of the Royal Irish Academy","volume":"20 1","pages":"61 - 82"},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87334539","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}

Signs of otter presence were noted at 65% of 441 sites surveyed. This figure suggests a decline in signs of otters since the 1980s. Highest occurrence of signs of otters was around lakes, with coastal sites having the lowest occurrence. Percentage occurrence of signs of otter varied considerably with respect to catchment. The highest levels were in Lough Melvin, County Fermanagh, and around the Foyle catchment, County Londonderry; fewest signs occurred along the Antrim coast. Signs of otter occurrence were higher in larger rivers and at unpolluted sites (68%) as compared to polluted sites (57%). Over 50% of otter spraints were composed of stickleback (Gasterosteus aculeatus), salmonids and cyprinids, with stickleback constituting the most frequently occurring prey category. The frequency of occurrence of eels (Anguilla anguilla) in otter diet was found to be consistently higher in spraints collected from smaller streams across all land class groups. The frequency of occurrence of most prey items differed significantly with catchment with the exception of salmonids, which occurred consistently in spraints collected throughout all catchments in Northern Ireland. The current investigation confirms that otters remain widespread in Northern Ireland. However, otters may be feeding on less profitable prey items. Further investigations into the relationship between water quality, prey availability and prey selection are required to fully understand the factors affecting otter diet in Northern Ireland.","PeriodicalId":55370,"journal":{"name":"Biology and Environment-Proceedings of the Royal Irish Academy","volume":"139 1","pages":"57 - 63"},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80802686","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, the extraordinary rapid vegetative growth of P. crispus requires that the species be harvested at the appropriate time to ensure the effectiveness of pollutant removal and minimise the risk of secondary pollution. The efficiency utilisation of wetland plant resources with a large amount of biomass is important in encouraging the harvest and sustainable self-support management of constructed wetlands. To screen the metabolites of P. crispus for tumor cell cytotoxicity, the total secondary metabolites of P. crispus were extracted and separated into three parts by using petroleum ether, ethyl acetate (EtOAc), and n-butyl alcohol. Thereafter, the cytotoxicity assay was conducted by using ES-2 human ovarian cancer and MDA-MB-231 human breast cancer cell lines. Results indicated that the P. crispus EtOAc extract showed anti-tumor activities against MDA-MB-231 cells. Morphological observation, cell cycle, and death analysis were conducted to evaluate the cytotoxic activity. Results showed that the P. crispus EtOAc extract could change the cell morphology and block the MDA-MB-231 cell cycle at the S phase and that the mechanisms of cell death were apoptosis and necrosis. This study provides a scientific basis for the potential utilisation of the constructed wetland plant P. crispus and has implications for the management of sustainable constructed wetland operation.","PeriodicalId":55370,"journal":{"name":"Biology and Environment-Proceedings of the Royal Irish Academy","volume":"45 1","pages":"79 - 87"},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80983902","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}

Muscle tissues were collected during bimonthly samplings from March 2010 to February 2011 in the Navachiste Bay (southwestern area of the Gulf of California). The pesticides γ-HCH and dieldrin were the substances most frequently detected throughout the collection period, while endosulfan 1, endosulfan 2, endrin, heptachlor epoxide, γ-HCH and methoxychlor were identified in 80% of the samples analysed. Other pesticides were found in 20%-60% of samples. No correlation was found among water physicochemical parameters and OCP concentration. The one-way variance analysis between OCP concentrations and collection months revealed no significant differences. The correlation between OCP concentrations and the weight or size of the fish was not significant, although between size and weight there was a significant correlation. During the study period, as a whole, the pesticides that showed the highest concentrations above 0.3ppm per sample were α-HCH (MAY-JUN-2010), dieldrin (JAN-FEB-2011), dieldrin (JULAGO-2010), methoxychlor (two samples in MAR-ABR-2010) (0.568, 0.533, 0.533, 0.503 and 0.330ppm, respectively). The pesticides aldrin, dieldrin, endosulfan (1 and 2), heptachlor epoxide, DDT and α-HCH, are listed in Appendix III of the Rotterdam Convention, which means that their use is illegal in most signatory countries.

Cavan, Ireland were carried out in the mid to late 2000s. Vegetation change between a pre-restoration baseline and surveys carried out 7–13 years post-restoration are assessed and demonstrate that 5.0ha of Sphagnum-rich regenerating bog vegetation has developed across the 26.9ha study site since restoration works were implemented. Although the restoration measures have triggered Sphagnum regeneration, increased the number of positive indicators species of Active Raised Bog (ARB) and initiated the process of peat-formation, the vegetation still lacks the presence and/or abundance of some critical ARB indicators. Moreover, 56% of the site is still dominated by vegetation with a low Sphagnum cover; 44% by Calluna vulgaris dominated vegetation and 12% by Molinia caerulea dominated vegetation. The key importance of topography in determining restoration potential is highlighted as extremely fine variations in topography appear to have resulted in significant differences in the vegetation that has developed. Any further increase in the area of regenerating bog on the cutover is likely to require enhanced restoration works such as cell bunding and additional marginal berms, the design of which will be informed using the modelling techniques outlined. Although not yet considered ARB habitat, the 19% of the Killyconny cutover that is classed as regenerating is clearly of conservation significance as a peat-forming habitat that supports assemblages of several specialist species and demonstrates how restoration works that raise water levels can initiate Sphagnum regeneration in a relatively short period of time.","PeriodicalId":55370,"journal":{"name":"Biology and Environment-Proceedings of the Royal Irish Academy","volume":"83 1","pages":"121 - 95"},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83789295","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 effects were also investigated in Irish roach (Rutilus rutilus) sampled downstream of Irish WWTPs. Control roach were sampled from a pristine salmon fishery river (River Deel) located in the west of Ireland. Histopathological and macroscopic analyses of downstream trout showed no adverse reproductive effects, compared to control fish sampled upstream of the WWTP. Statistically significant (p <0.05) populations of wild roach from three sampled Shannon basin rivers were, however, observed to be phenotypically intersex (ovo-testis) when compared to the control river.
