Ligia italica Fabricius is a day-active isopod on the shores of Madeira. The population migrates up and down the shore with the tide, browsing on lichens and macroalgae. Shore bird predation is negligible; foraging wall lizards are the only daytime predators. Ligia italica retreats into crevices at night. It exploits plant material within supralittoral and intertidal pools and enters pools with salinities as high as 74‰. Ligia italica emerges from pools at intervals to breathe in air; such emersion lasts no more than two minutes. Ligia italica on Madeira has no colour change ability, the isopods remaining dark grey/black whatever the background.
Atlantic bonito, Sarda sarda, is one of the representatives of the Scombridae family in the Adriatic Sea. Larvae and juveniles have been found and described in the area, but no information has been published regarding adults spawning in the Adriatic Sea. To explore the strong possibility that Atlantic bonito are reproducing in the Adriatic Sea, 122 specimens of adult Atlantic bonito were collected from a purse seine net ‘palamidara’ over four seasons in 2017. The fork length of the analysed specimens varied from 37.5 to 60.8 cm, with a mean of 48.83 ± 5.59 cm, while total body weight varied between 742.68 and 3102.59 g, with a mean value of 1700.49 ± 543.82 g. Gonadosomatic index values showed an increasing trend from autumn (0.123 for males, 0.897 for females) until spring, while in the summer, they reached their maximum values (3.609 for males, 5.604 for females). This trend was also confirmed by histological and macroscopic analyses of gonads, which suggested that the Atlantic bonito spawning season is in the spring-summer in the Adriatic Sea. Hence, this confirms that this species is spawning in the Adriatic Sea.
The first record of the ophiuroid family Ophiohelidae from the Mediterranean Sea is reported. It consists of the description of the new record of Ophiomyces grandis from the Mallorca Channel seamounts in the Balearic Islands, western Mediterranean, where it shows high abundances. We present both the morphological description of the individuals collected and, for the first time, the cytochrome oxidase subunit I (COI) sequence of this species. The morphological traits of our specimens match the available descriptions of O. grandis. On the other hand, molecular analyses show a large genetic distance between O. grandis and Ophiomyces delata, the two species being very similar morphologically. Despite the high abundances of O. grandis reported here, previous surveys in the Mallorca Channel seamounts using ROV did not detect it, emphasizing the importance of beam trawl sampling to improving the biodiversity description of these geomorphological sea bottom features.
Conferences are an excellent opportunity to hear about the latest news in your field. They are also a great chance to meet like-minded people, share experiences, discuss ideas and gain inspiration. Friendships, collaborations, new research directions, invitations and job offers can all arise from conversations at conferences. Conferences range from small regional or national gatherings to huge international meetings. They may address a particular topic or may be a more general meeting of a learned society, including symposia on a variety of topics as well as society business meetings. Conferences may have only one session, with all delegates in the same room at the same time or may have multiple concurrent sessions in a conference venue where all the rooms and corridors look the same and it’s very easy to get lost. Most conferences include keynote or plenary presentations by major researchers in the field. This is a great chance to meet the people whose articles you have read and admired. In this chapter, I cover preparing and submitting an abstract, then attending a conference. Next, I provide general advice on presentations, then cover preparing and presenting oral and poster presentations. I end with conference etiquette.
Good research design includes choosing what to measure and how to measure it. We can’t measure everything. Fortunately, clear predictions dictate the measurements we need to make to test them. This chapter provides general advice on methods, then covers the importance of the validity, accuracy, sensitivity of the measures we use. I end with a reminder that methods must also be feasible.
Disseminating our findings is part of the scientific process, so that others know what we found. Not making our results available leads to duplication of effort because other researchers don’t know we did the work. Publication bias arises when researchers don’t publish findings because they are non-significant. We may need to publish to advance our career, but this is not the purpose of scientific articles. Confusing these two aims can lead to questionable research practices. This chapter goes through the of submitting a manuscript to a peer-reviewed journal. Peer review involves the scrutiny and evaluation of our work by experts. I begin with how to choose a journal, and things to consider before you submit, then I explain the cover letter, submission, and the review process. I explain the editor’s decision, what to do if your manuscript is rejected, revising your manuscript and resubmitting it. Finally, I cover what happens after your manuscript is accepted.
The ability to write is an essential component of research. We write to communicate with readers. Our readers include funding bodies, thesis examiners, manuscript editors, reviewers, or readers of a journal. In each case, we write to convince a reader of our argument. In reports, we also write to allow a reader to check and interpret our findings for themselves. Good writing conveys information to readers as clearly and simply as possible. Poor writing obscures meaning, frustrates the audience and puts them off reading our work. Poorly crafted writing can make the reader suspect that our science may also be confused. To avoid this, write clearly, simply, precisely and concisely. Writing takes practice. In this chapter I cover general points, which apply to all scientific writing. I begin with advice on drafting, and the need to revise, obtain feedback and revise your draft again. This iterative process can come as a surprise to students accustomed to submitting work for a deadline, then forgetting about it. I then cover general style, followed by specific topics including structure and clarity.
A clearly formulated research question is vital in science because it determines the data we need to collect, the methods we use, and, ultimately, the success of a project. Developing a research question is an iterative process of reading and thinking, as we define a problem and specify the contribution we hope to make to resolving it. This is not easy, and we learn through experience, and (if we’re lucky) from our mentors. In this chapter I first explain research questions and the case studies we use to address them, then look at where questions come from. I examine what makes a good research question and end with why reading is essential to the development of research ideas
Fieldwork can be exciting, and even addictive, but it can also be daunting and dangerous. Fieldsites range from a tent to established research stations. You may be close to home, or on the other side of the world. National researchers may be just as foreign to a local area as non-national researchers. You may be in a familiar environment or in a very unfamiliar one. Fieldwork often involves sharing living space with other people, and with wildlife. In this chapter I begin with what it takes to be a fieldworker, then cover permissions and logistics, field kit, personal safety, the social context, LGBTQIA+ concerns, natural hazards, physical health, mental health, and returning home.
Primates are an order of mammals which share a set of traits inherited from a common ancestor that distinguishes them from all other mammals. These derived traits are not all unique to primates and none of the individual traits is shown by all primates. Primates range in body mass from the 30 g Madame Berthe's mouse lemur to around 250 kg for a male Grauer's gorilla. This variation in size is in line with that found in other mammalian orders and is closely associated with what they eat (diet), how they move (locomotion), and their behaviour. In this chapter, I provide a general introduction to the primates and their evolutionary adaptations (traits produced by natural selection for their current function), including their distribution and habitats, adaptations to life in the trees, diet and dietary adaptations, brains and sensory traits, life history and reproduction, behaviour and locomotion, social behaviour and interactions with other species. I then survey the major groups of primates. Throughout the chapter, I highlight terms that are common in the literature but are problematic.
Data analysis and interpretation allow you to test your predictions and interpret your results. This is an exciting time and can be daunting because it’s a big change from data collection. It’s very unlikely that you will have collected exactly the data you set out to collect, but your analysis plan will keep you on track and avoid the dangers of aimlessly exploring your dataset. You will probably need further statistical advice at this stage. This chapter guides you through data preparation, initial data analysis, hypothesis testing, calculating your effect sizes and confidence intervals, interpreting your results and extrapolating from them.
The Bay of Málaga is located in a high biodiversity and productivity area that harbours a wide variety of commercial species exploited by different fishing fleets. Benthic and demersal fauna from circalittoral soft bottoms have been studied using a benthic dredge (BD) (8 sampling stations) and an otter trawl (OT) (8 sampling stations on a seasonal basis). Some sediment and water column variables, as well as the trawling activity, have also been studied and used for analysing their linkage with the fauna. A total of 287 species have been found in these bottoms and fish, molluscs and crustaceans represented the most diverse and abundant faunistic groups. A new record of the decapod Hippolyte leptometrae for Spanish waters is also included in this study. Some multivariate analyses using BD samples indicated the presence of three assemblages, but these seem to represent different facies of a single benthic community due to the absence of acute sediment changes and significant differences in the fauna. OT samples only displayed differences related to seasons but not to sediment types or depth. These seasonal differences seem to be linked to biological and ecological features of both dominant and/or commercial species. Mud and organic matter contents (%OM) in sediment, as well as the temperature, were the main variables linked to the spatial distribution of the benthic community identified with BD, whereas medium and coarse sand as well as gravel contents were the main variables linked to the changes of the epibenthic and demersal assemblage resulting from OT samples. The information of this study is of importance for improving the knowledge on the biodiversity of circalittoral soft bottoms of the Mediterranean and Alboran Sea as well as for the potential creation of a Marine Fisheries Reserve in the Bay of Málaga.
Once you have a research question, hypotheses and predictions, study design, detailed methods and data analysis plan, you have all you need to write a research proposal. Writing a proposal clarifies your thoughts and ensures that they are feasible. You can share a proposal with other people to get feedback on your plans and use it to underpin funding applications. Whatever you propose to study, you are likely to need funding for equipment, supplies, transport, and other expenses. You may also need to cover tuition fees and living expenses. When you apply for funding you enter a competition. Most applications are unsuccessful. Some of the factors affecting success are out of your hands, such as the success rate, and luck. Some, however, are not, and excellent proposals share characteristics. In this chapter, I explain how you can improve your chances of obtaining funding by applying to appropriate organisations, tailoring your proposal carefully, following guidelines, and seeking feedback while preparing your application. I provide general points on writing and details of each section of a proposal. Finally, I address how to deal with the outcome of the funding decision. I focus on relatively small grants appropriate for PhD students and post-doctoral scholars. Much of the advice also applies to PhD project proposals.
