The gastropod fauna of the Epipalaeolithic shell midden in the Vestibulo chamber of Nerja Cave (Málaga, southern Spain)
2011
The sedimentary record of the Vestibulo, Mina and Torca chambers in the ancient entrance of Nerja Cave (Malaga, southern Spain) developed between around 30 and 3.6 ka cal BP. The long record of human occupation shows a dominance of terrestrial snails associated with the Gravettian, with a continuation of these types in the Solutrean when marine shells begin to be introduced. During the Magdalenian, marine bivalves are dominant. Marine molluscs reach a maximum during the Epipalaeolithic, giving rise to a shell midden formed primarily by Mytilus edulis and diverse species of Patella. The Epipalaeolithic shell midden occurs in Unit 4 and can be dated to the PleistoceneeHolocene boundary. This …
The Role of Spatial Exploration and Territoriality in Establishing Gilthead Seabream (Sparus aurata) Hierarchies, and Their Effects upon Underlying S…
2023
Territoriality, spatial exploration and social hierarchy are strictly related behaviors in gregarious fishes, and are often under-appreciated in farms where the individuals are confined within crowded spaces. In this study, we investigated the role of spatial exploration, elucidating the importance of time upon forming the social organization, and the role of the territoriality in gilthead seabream (Sparus aurata), using two experimental approaches. In the first approach, three fish were placed sequentially in the aquarium with an interval of two days (sequential model), while in the second (simultaneous model), two fish were simultaneously placed in an aquarium divided by a barrier which w…
Forehead Patch Size Predicts the Outcome of Male–Male Competition in the Pied Flycatcher
2013
Males of many animal species express ornaments that affect their reproduction opportunities through male–male competition or female mate choice. Such ornaments can, for example, inform conspecifics about the fighting ability, condition or territory ownership of the bearer. Pied flycatcher (Ficedula hypoleuca) males have a conspicuous white forehead patch that varies greatly in size. We examined whether the white forehead patch is an intrasexually selected trait in a Finnish population. We artificially manipulated forehead patch size to represent two naturally occurring extremes and competed males against each other in the presence of a female. Males with a large forehead patch were more agg…
Unipedal vertical jumping performance in soccer players
2011
Introduction: The muscular strength between the dominant and non-dominant legs of soccer players has been the centre of research that has highlighted contradictory results. Several researchers have reported symmetry between the dominant and non-dominant legs, whereas others suggest the existence of a significant asymmetry. Kicking and cutting skills in soccer are clearly unilateral, require asymmetrical motor patterns and can lead to the development of asymmetrical adaptations in the musculoskeletal function of the lower limbs (Fousekis et al., 2010). The purpose of this study was to examine the flight time [FT] and jump height [JH] during a vertical one-legged countermovement jump by domin…
Do native white-clawed crayfish impact macroinvertebrate assemblages in Mediterranean limestone headwaters?
2019
Crayfish are among the largest aquatic macroinvertebrates in rivers and streams. Their trophic ecology is important for the understanding of the functioning of benthic communities. This is relevant in key areas, such as headwaters, as they partly condition the processes occurring downstream. To shed light on the effects of native white-clawed crayfish,Austropotamobius pallipes, on local macroinvertebrate assemblages from running headwaters, a three-month mesocosm-based field study was designed. Collection and subsequent analysis of benthic samples under different crayfish density levels yielded a set of metrics indicative of short-term impacts at general and taxonomic scales. Neither signif…
Increasing temperature and productivity change biomass, trophic pyramids and community‐level omega‐3 fatty acid content in subarctic lake food webs
2021
Climate change in the Arctic is outpacing the global average and land-use is intensifying due to exploitation of previously inaccessible or unprofitable natural resources. A comprehensive understanding of how the joint effects of changing climate and productivity modify lake food web structure, biomass, trophic pyramid shape and abundance of physiologically essential biomolecules (omega-3 fatty acids) in the biotic community is lacking. We conducted a space-for-time study in 20 subarctic lakes spanning a climatic (+3.2 degrees C and precipitation: +30%) and chemical (dissolved organic carbon: +10 mg/L, total phosphorus: +45 mu g/L and total nitrogen: +1,000 mu g/L) gradient to test how temp…
Dzimuma attiecību loma un savstarpējā apmierinātība transkulturālās romantiskajās partnerattiecībās starp indonēzijas sievietēm un rietumu pasaules v…
2022
Šajā pētījumā “Dzimtes attiecību loma un amierinātība romantiskajās partnerattiecībās starp Indonēzijas sievietēm un rietumu pasaules vīriešiem” tiek pietuvināti apskatītas romantiskās partnerattiecības starp indonēziešu sievietēm un Rietumu pasaules vīriešiem jeb bule. Mērķis bija noskaidrot kāda ir dzimumu loma savstarpējā dinamika partnerattiecību kontekstā, kādi sociāli, ekonomiski un politiski aspekti ir iesaistīti vietējo sieviešu izvēlē par labu bule vīriešiem un kādi ir šo partnerattiecību modeļi un pieredzes. Uzmanība tiks vērsta pret iepriekš minētajām izpausmēm šajās attiecībās. Indonēzijas salā Bali, līdz ar tās aktualitāti kā tūrisma galamērķim, novērojama cilvēku sociālā, kult…
Personality predicts social dominance in female zebra finches, Taeniopygia guttata, in a feeding context.
2011
6 pages; International audience; Although personality has been defined as a suite of correlated behaviours, most studies of animal personality actually consider correlations between a few traits. We examined the repeatability and correlational structure of five potential personality traits (activity, neophobia, exploratory tendencies, risk-taking behaviour and obstinacy), in female zebra finches. In addition, we assessed to what extent personality influenced social dominance in a feeding context in this gregarious species. All personality traits were found to be highly repeatable within individuals. In addition, except for obstinacy, all of them were related to each other, thus defining a b…
Roy’s Inglish in The God of Small Things: A Language for Subversion, Reconciliation and Reassertion
2011
Abstract:In The God of Small Things, Arundhati Roy separates English from Englishspeakers. She reappropriates the language not only to portray complex characters and narrative themes, but also to create a postcolonial discourse that criticizes, questions and subverts the old dominance of the imperial colonizer. Mainly addressed to a western audience, the use of Inglish in this novel is a crucial factor to reveal the development of a hybrid conscience, reassert the Indian identity and make the reader feel displaced from their native tongueKeywords: English language, postcolonial, hybridity, Indian identity, discourseTítulo en español: El Inglish de Roy en The God of Small Things: Una lengua …
Does Car Sharing Contribute to Urban Sustainability from User-Motivation Perspectives?
2021
Mobility, its current state and development perspectives in the future creates challenges with respect to sustainability, the first of which is the uncontrolled increase in greenhouse gas emissions in the last few decades, while road transport is one of the “sinners” creating long-term negative impact. The second is the dominance of car travel and car usage in the passenger transportation segment before the latest COVID-19 pandemic accelerated environmental problems. Although recent trends show new, greener patterns in consumption, there is still a relatively low share of consumers acknowledging the importance of sustainable and green preferences. This research study aims to investigate car…
