Synthetic Microplastic Abundance And Composition Along A Longitudinal Gradient Traversing The Subtropical Gyre In The North Atlantic Ocean, Winnie Courtene-Jones, Simon Van Gennip, Juliette Penicaud, Emily Penn, Richard C. Thompson

School of Biological and Marine Sciences

Plastic pollution has been reported in the North Atlantic Ocean since the 1970s, yet limited data over subsequent decades pose challenges when assessing spatio-temporal trends in relation to global leakages and intervention strategies. This study quantified microplastics within the upper ocean along a longitudinal transect of the North Atlantic and its subtropical gyre. Microplastics were sampled from surface and subsurface (−25 m) water using a manta trawl and NIKSIN bottle respectively. The surface water polymer community varied significantly between geographic positions (‘inshore’, ‘gyre’, ‘open ocean’), and was significantly influenced by fragment quantity. Compared to other positions, the North Atlantic gyre …

Human Affinity For Rivers, Yichu Wang, Alistair G.L. Borthwick, Jinren Ni Jan 2022

Human Affinity For Rivers, Yichu Wang, Alistair G.L. Borthwick, Jinren Ni

School of Engineering, Computing and Mathematics

Human civilization prospers along rivers worldwide. Here, we investigated human–river relations by revealing the linkage between water and habitability for human settlements, and socioeconomic and cultural development across China. We found that human–water co-occurrence relationships are self-similar over sub-basins for different scales of stream-order in the river networks. According to the earlier complete demographic census conducted during the reign of the Qing Dynasty (1776), there has been a general tendency for inhabitants to live close to rivers, characterized by population density associated with habitability cored by water under a near-natural state, which still remains to date (2019) even after long-term …

School of Biological and Marine Sciences

Black cumin (Nigella sativa) is an important medicinal plant in the pharmacological industry. It is cultivated on a commercial scale, but its seeds have a slow, unsynchronized germination rate. Enhancing seed germination is crucial for improving the production of black cumin. The influence of presowing treatments [gibberellic acid (GA3), potassium nitrate, salicylic acid, and stratification at 4 °C] on seed germination was assessed. Seed germination was determined daily for 30 days, and germination parameters, including final germination percentage (FGP), corrected germination rate, number of days to reach 50% of FGP, and seedling length vigor index, were evaluated. Endogenous contents of …

School of Biological and Marine Sciences

Marine ecosystems have been used, impacted by, and managed by human populations for millennia. As ecosystem degradation has been a common outcome of these activities, marine management increasingly considers ecosystem restoration. Currently, there is no coherent data recording format or framework for marine restoration projects. As a result, data are inconsistently recorded and it is difficult to universally track progress, assess restoration's global effectiveness, reduce reporting bias, collect a holistic suite of metrics, and share information. Barriers to developing a unified system for reporting marine restoration outcomes include: reaching agreement on a framework that meets the needs of all users, …

Individual And Collective Behaviour Of Fish Subject To Differing Risk-Level Treatments With A Sympatric Predator, Alexander D.M. Wilson, Timothy M. Schaerf, Ashley J.W. Ward Jan 2022

Individual And Collective Behaviour Of Fish Subject To Differing Risk-Level Treatments With A Sympatric Predator, Alexander D.M. Wilson, Timothy M. Schaerf, Ashley J.W. Ward

School of Biological and Marine Sciences

The ability to adapt behaviour according to context is vital to the success of many organisms, particularly when it comes to mitigating risk, across time and space, in unpredictable environments. While many studies have examined the role of predation threat in shaping behaviour, very few have quantitatively investigated prey responses across different elements of perceived risk or ecological contexts. Here, we present a detailed analysis of how mosquitofish (Gambusia holbrooki) adapt their individual and collective behaviour in five experimental treatments designed to replicate different core elements of predator threat. As risk increased, within and across treatments, fish decreased movements across …

Borrowed Capital And Factors Affecting Its Utilization Among Rice Farmers In The Province Of Albay, Philippines, Elmer A. Lorenzana

Journal of Public Affairs and Development

Agricultural credit programs provide opportunities for farmers to acquire the necessary farm inputs and apply appropriate technologies. However, it remains a challenge for farmers to use the credit for what it was intended for. This study aimed to measure the factors affecting the utilization of borrowed capital of 233 randomly selected rice farmers from the province of Albay using binary logit as its analytical procedure. The factors influencing the utilization of borrowed capital are the type of the optimization behavior of the farmers, sex, family size, and farm size. The output maximizers and the male farmers have a higher probability …

Introduction: Dural tails are thickened contrast-enhancing portions of dura associated with some meningiomas. Prior studies have demonstrated the presence of tumor cells within the dural tail, however their inclusion in radiation treatment fields remains controversial. We evaluated the role of including the dural tail when treating a meningioma with stereotactic radiation and the impact on tumor recurrence.

Methods: This is a retrospective, single-institution, cohort study of patients with intracranial World Health Organization (WHO) grade 1 meningioma and identified dural tail who were treated with stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT) from January 2012 to December 2018. SRS and …

Open educational resources, or OER, are teaching materials that reside in the public do-main and are available under an open license. While the creation of high-quality materials and cyberinfrastructure to share these resources is important, OER are much more than static resource repositories. Vibrant OER communities function as collaboration hubs and often include librarians, instructional technologists, instructors, education researchers, funders, open-source software developers, and college administrators. Together, these in-dividuals work as a community to respond to changes in the education landscape, support student learning impacts both in terms of cost savings and student retention, and solve issues related to broadly …

Geography

Amplified by warming temperatures and drought, recent outbreaks of native bark beetles (Curculionidae: Scolytinae) have caused extensive tree mortality throughout Europe and North America. Despite their ubiquitous nature and important effects on ecosystems, forest recovery following such disturbances is poorly understood, particularly across regions with varying abiotic conditions and outbreak effects. To better understand post-outbreak recovery across a topographically complex region, we synthesized data from 16 field studies spanning subalpine forests in the Southern Rocky Mountains, USA. From 1997 to 2019, these forests were heavily affected by outbreaks of three native bark beetle species (Dendroctonus ponderosae, Dendroctonus rufipennis and Dryocoetes …
