Diclidophora luscae (Monogenea: Diclidophoridae) in pouting, Trisopterus luscus (Linnaeus, 1758) from the northeast Atlantic; epidemiology, morphology, molecular and phylogenetic analysis

Diclidophora (Monogenea) species are gill parasites with a stenoxenic specifcity occurring only in Gadiformes. Epidemiologi‑cal, morphological, molecular and phylogenetic studies were performed on 594 Diclidophora specimens collected from 213 Trisopterus luscus captured in the northeast Atlantic of the Portuguese coast during 2012, 2013 and 2020. Prevalence, parasite abundance and infection intensity were determined. Positive correlation between fsh weight and length and infection intensity was observed. The efects of preservation on the parasite morphological features were studied, highlighting that specimen’s identifcation should be reinforced by molecular studies. A sequence of D. luscae capelanii from T. capelanus captured in the Mediterranean Sea included in the 28S rDNA molecular analysis was nested within a robust D. luscae clade. Data analysis suggested that this species is in fact D. luscae, which is compatible with T. luscus and T. capelanus. The identity of fsh hosts was confrmed by barcoding. For the frst time, data on the infection parameters is shown, highlighting the importance of including this parasite in the monitoring plans for a holistic approach with possible efects for the management of pouting resources aiming of attaining sustainable development and biodiversity conservation measures, according to the 14th objective of the 2030 agendainfo:eu-repo/semantics/publishedVersio

Recursos forrageiros regionais conservados como feno para a alimentação de bovinos na região de Corumbá, MS.

A produção de feno para fornecimento ao gado durante a estação seca, com o uso de espécies forrageiras regionais com ampla distribuição nos assentamentos rurais da região de Corumbá/MS, representa uma alternativa simples e economicamente viável para aumentar à produtividade dos rebanhos leiteiros, além de se configurar em uma etapa da transição agroecológica, ou seja, a substituição de insumos externos por alternativas disponíveis localmente.bitstream/CPAP-2010/57325/1/CT87.pd

A serologia para avaliação do papel dos predadores em olival biológico

A oliveira, sendo uma planta mediterrânica, encontra-se bem adaptada em Portugal. Apesar de ser uma cultura com poucos problemas fitossanitários, por vezes e sujeita à acção de algumas pragas e doenças. De entre as pragas de artrópodos destacam-se a traça da oliveira, Prays oleae (Bern.), a mosca da azeitona, Bactrocera oleae (GmeL) e a cochonilha negra, Saissetia oleae (Oliv.). No entanto, as populações destes inimigos podem ser mantidas abaixo do nível económico de ataque por factores abióticos e/ou por outros artrópodos, espécies predadoras e parasitóides, que contribuem para a estabilidade da biocenose no olival A valorização destes auxiliaras é, assim, um factor preponderante na protecção contra pragas da oliveira, nomeadamente em modo de produção biológico

Duality, Quantum Skyrmions and the Stability of an SO(3) Two-Dimensional Quantum Spin-Glass

Quantum topological excitations (skyrmions) are analyzed from the point of view of their duality to spin excitations in the different phases of a disordered two-dimensional, short-range interacting, SO(3) quantum magnetic system of Heisenberg type. The phase diagram displays all the phases, which are allowed by the duality relation. We study the large distance behavior of the two-point correlation function of quantum skyrmions in each of these phases and, out of this, extract information about the energy spectrum and non-triviality of these excitations. The skyrmion correlators present a power-law decay in the spin-glass(SG)-phase, indicating that these quantum topological excitations are gapless but nontrivial in this phase. The SG phase is dual to the AF phase, in the sense that topological and spin excitations are respectively gapless in each of them. The Berezinskii-Kosterlitz-Thouless mechanism guarantees the survival of the SG phase at $T \neq 0$, whereas the AF phase is washed out to T=0 by the quantum fluctuations. Our results suggest a new, more symmetric way of characterizing a SG-phase: one for which both the order and disorder parameters vanish, namely $= 0$, $=0$, where $\sigma$ is the spin and $\mu$ is the topological excitation operators.Comment: 10 pages, 1 figur

Report on Tests and Measurements of Hadronic Interaction Properties with Air Showers

We present a summary of recent tests and measurements of hadronic interaction properties with air showers. This report has a special focus on muon density measurements. Several experiments reported deviations between simulated and recorded muon densities in extensive air showers, while others reported no discrepancies. We combine data from eight leading air shower experiments to cover shower energies from PeV to tens of EeV. Data are combined using the z-scale, a unified reference scale based on simulated air showers. Energy-scales of experiments are cross-calibrated. Above 10 PeV, we find a muon deficit in simulated air showers for each of the six considered hadronic interaction models. The deficit is increasing with shower energy. For the models EPOS-LHC and QGSJet-II.04, the slope is found significant at 8 sigma.Comment: Submitted to the Proceedings of UHECR201
