A hypothesis of a redistribution of North Atlantic swordfish based on changing ocean conditions

Conflicting trends in indices of abundance for North Atlantic swordfish starting in the mid-to late 1990s, in the form of fleet specific catch-per-unit-effort (CPUE), suggest the possibility of a spatial shift in abundance to follow areas of preferred temperature. The observed changes in the direction of the CPUEs correspond with changes in trends in the summer Atlantic Multidecadal Oscillation (AMO), a long term mode of variability of North Atlantic sea surface temperature. To test the hypothesis of a relation between the CPUE and the AMO, the CPUEs were made spatially explicit by re-estimating using an “areas-as-fleets” approach. These new CPUEs were then used to create alternative stock histories. The residuals of the fit were then regressed against the summer AMO. Significant, and opposite, relations were found in the regressions between eastern and western Atlantic areas. When the AMO was in a warm phase, the CPUEs in the western (eastern) areas were higher (lower) than predicted by the assessment model fit. Given the observed temperature tolerance limits of swordfish, it is possible that either their preferred habitat, prey species, or both have shifted spatial distributions resulting in conflicting CPUE indices. Because the available CPUE time series only overlaps with one change in the sign of the AMO (~1995), it is not clear whether this is a directional or cyclical trend. Given the relatively localized nature of many of the fishing fleets, and the difficulty of separating fleet effects from changes in oceanography we feel that it is critical to create CPUE indices by combining data across similar fleets that fish in similar areas. This approach allowed us to evaluate area-specific catch rates which provided the power to detect basin-wide responses to changing oceanography, a critical step for providing robust management advice in a changing climate.Postprin

However, our current knowledge of pollen is rather limited with respect to its extinction capacity, its optical properties and how these vary with atmospheric water content. Understanding their water absorption capacity can improve our understanding of their radiative effects and, thus, improve climate models. In this work, an electrodynamic Paul trap was coupled to a cavity ring down spectroscopy (CRDS) to directly measure the ring down time () of four individual types of pollen particles: Olea, Fraxinus, Populus and Salix exposed to changing relative humidity (RH). Resonant structures in values between ∼90 and 45 % RH indicated that pollen was wettable at high RHs. was used to calculate light extinction cross-section at 532 nm as a function of RH. Optical growth factor () was evaluated as the ratio between and From , the semi-empirical single hygroscopicity parameter () was found to be 0.038–0.058 for the four pollen types. Under controllable treatment of the water content and an adequate selection of complex refractive index , CRDS- data was fitted to theoretical from Mie theory. The reasonable agreement achieved allowed for gaining knowledge about the and how particle size shrugged during dehydration. As a result, a climate-lowering effect of Olea pollen particles, which contain a fraction of scattered aerosol, should be considered in the models.Spanish Ministry of Science and Innovation (PID2020-12001-5RB-I00)Junta de Andalucía Excellence: ADAPNE (P20-00136), AEROPRE (P-18-RT-3820), FEDER Una manera de hacer Europa, EQC2019-006423-P, INTEGRATYON (PID2020-117825GB-C21, PID2020-117825GB-C22)European Union's Horizon 2020 CTRIS.IMP 871115ATMO-ACCESS 101008004ACTRIS-España (RED2022-134824-E)FEDER/Junta de Andalucía-Consejería de Transformación Económica, Industria, Conocimiento y Universidades DEM3TRIOS (A-NM-430-UGR20)University of Granada LS2022-1, PP2022.PP.3

Assessment of oceanographic services for the monitoring of highly anthropised coastal lagoons: The Mar Menor case study

Ocean monitoring systems are designed for continuous monitoring to track their evolution and anticipate environmental issues. However, they are often based on IoT systems that offer little spatial coverage and are hard to maintain. Satellite remote sensing offers good geographical coverage but they also face several challenges to become a monitoring system. This paper introduces an easy-to-use software tool to crawl water-quality data from up to 6 satellite instruments from the ESA and NASA. Particularly, Chl-a data is deeply analyzed in terms of reliability and data coverage for a highly anthropised coastal lagoon (Mar Menor, Spain), where serious socio-environmental issues are happening. Our results show a good linear correlation between in situ data and SRS data, reaching values close to 0.9, and stating the relevance of organic matter inputs from ephemeral streams in Chl-a concentrations. Moreover, temporal granularity is increased from 5 to 1.5 days by combining SRS sources.Preprin

Accesibilidad a Internet: requisitos para la calidad en la docencia e investigación

A good Internet platform for teaching and research must be accessible, independently of the computer platform used, language and other peculiarities (personal or external). This work analyzes the current limitations of Internet access, as well as the potentialities that would represent an access being truly independent of the computer platform, discapacities, availability and speed of access, language and legislation. Thus, the benefits for a more accesible network for lecturing and investigation, overcoming the geographic location or possible discapacity, would be immediate and would have a broad impact spectrum. A more accesible Internet would enhace not only the dissemination of the information, approaching us to the 'global village', but also others aspects like university principles and values that sould be considered: an improvement of the equality of opportunities and the access to the culture and the education, that are the basis of the progress and the individual and collective liberties.Una buena plataforma de docencia e investigación en la red debe ser accesible, independientemente del entorno informático, idioma y condicionantes( personales o externos). Es este trabajo se analizan, por una parte, las limitaciones actuales que se presentan en el acceso a Internet, y por otra las potencialidades que tendría un acceso un acceso independiente de las plataforma informáticas, discapacidades, disponibilidad y velocidad de acceso, idioma y legislación. Así, los beneficios para la docencia y la investigación de una red más accesible, por encima de la localización geográfica o posible discapacidad, serán inmediatos y redundaría en otros campos. Una Internet más accesible abriría una nueva vía no sólo para la difusión de la información, acercándonos a la 'aldea global', sino también para otros aspectos de lo que entenderemos como principios y valores universitarios y que deben ser considerados: una mejora en la igualdad de oportunidades y en el acceso a la cultura y la formación, que son las bases del progreso y de las libertades tanto individuales como colectivas

A shoot Fe signaling pathway requiring the OPT3 transporter controls GSNO reductase and ethylene in arabidopsis thaliana roots

Ethylene, nitric oxide (NO) and glutathione (GSH) increase in Fe-deficient roots of Strategy I species where they participate in the up-regulation of Fe acquisition genes. However, S-nitrosoglutathione (GSNO), derived from NO and GSH, decreases in Fe-deficient roots. GSNO content is regulated by the GSNO-degrading enzyme S-nitrosoglutathione reductase (GSNOR). On the other hand, there are several results showing that the regulation of Fe acquisition genes does not solely depend on hormones and signaling molecules (such as ethylene or NO), which would act as activators, but also on the internal Fe content of plants, which would act as a repressor. Moreover, different results suggest that total Fe in roots is not the repressor of Fe acquisition genes, but rather the repressor is a Fe signal that moves from shoots to roots through the phloem [hereafter named LOng Distance Iron Signal (LODIS)]. To look further in the possible interactions between LODIS, ethylene and GSNOR, we compared Arabidopsis WT Columbia and LODIS-deficient mutant opt3-2 plants subjected to different Fe treatments that alter LODIS content. The opt3-2 mutant is impaired in the loading of shoot Fe into the phloem and presents constitutive expression of Fe acquisition genes. In roots of both Columbia and opt3-2 plants we determined 1-aminocyclopropane1-carboxylic acid (ACC, ethylene precursor), expression of ethylene synthesis and signaling genes, and GSNOR expression and activity. The results obtained showed that both 'ethylene' (ACC and the expression of ethylene synthesis and signaling genes) and 'GSNOR' (expression and activity) increased in Fe-deficient WT Columbia roots. Additionally, Fe-sufficient opt3-2 roots had higher 'ethylene' and 'GSNOR' than Fe-sufficient WT Columbia roots. The increase of both 'ethylene' and 'GSNOR' was not related to the total root Fe content but to the absence of a Fe shoot signal (LODIS), and was associated with the up-regulation of Fe acquisition genes. The possible relationship between GSNOR(GSNO) and ethylene is discussed

Ethylene and phloem signals are involved in the regulation of responses to Fe and P deficiencies in roots of strategy I plants

Iron (Fe) and phosphorus (P) are two essential mineral nutrients whose acquisition by plants presents important environmental and economic implications. Both elements are abundant in most soils but scarcely available to plants. To prevent Fe or P deficiency dicot plants initiate morphological and physiological responses in their roots aimed to specifically acquire these elements. The existence of common signals in Fe and P deficiency pathways suggests the signaling factors must act in conjunction with distinct nutrient-specific signals in order to confer tolerance to each deficiency. Previous works have shown the existence of cross talk between responses to Fe and P deficiency, but details of the associated signaling pathways remain unclear. Herein, the impact of foliar application of either P or Fe on P and Fe responses was studied in P- or Fe-deficient plants of Arabidopsis thaliana, including mutants exhibiting altered Fe or P homeostasis. Ferric reductase and acid phosphatase activities in roots were determined as well as the expression of genes related to P and Fe acquisition. The results obtained showed that Fe deficiency induces the expression of P acquisition genes and phosphatase activity, whereas P deficiency induces the expression of Fe acquisition genes and ferric reductase activity, although only transitorily. Importantly, these responses were reversed upon foliar application of either Fe or P on nutrient-starved plants. Taken together, the results reveal interactions between P- and Fe-related phloem signals originating in the shoots that likely interact with hormones in the roots to initiate adaptive mechanisms to tolerate deficiency of each nutrient
