Dyslexia Skelley and Gasca-Álvarez, new genus (Coleoptera: Erotylidae: Erotylinae: Erotylini), is described and illustrated. The genus is comprised of four new species, all described by Skelley and Gasca-Álvarez: D. belamyi, D. dathomirria, D. pulcricolor, and D. tomasi. The unique broad head structures of this genus are characterized and compared with other genera. Problems associated with the taxonomy of Erotylini are discussed. Resumen. Se describe y se ilustra a Dyslexia Skelley y Gasca-Álvarez, nuevo género (Coleoptera: Erotyli­dae: Erotylinae: Erotylini). El género está formado por cuatro especies nuevas, todas descritas por Skelley y Gasca-Álvarez: D. belamyi, D. dathomirria, D. pulcricolor, y D. tomasi. Las estructuras únicas de la cabeza ancha de este género son caracterizadas y comparadas con otros géneros. Se discuten problemas relacionados con la taxonomía de Erotylini

A Survey of the Reef-Related Medusa (Cnidaria) Community in the Western Caribbean Sea

The species composition, distribution, and abundance of medusae collected during a 4-day plankton survey in a reef system of the Mexican Caribbean were studied. Highest mean medusae abundance was observed over the fore-reef zone and in daytime samples. Lowest abundances occurred in the reef lagoon and at dusk. Seventeen species were identified, with Liriope tetraphylla, Aglaura hemistoma, Cubaia aphrodite, and Sarsia prolifera being the most abundant. They belong to a group of medusae dominant along the world\u27s second largest barrier reef. Cluster analysis revealed primary (fore-reef) and secondary (reef lagoon, channel) oceanic groups, showing the strong oceanic influence along and across the reef system. Day-to-day variation in the reef medusan community seemed relatively unimportant. The community structure of the reef medusa fauna appeared to be quite uniform despite the expected migratory behavior of these predators, tidal exchange across the reef, introduction of oceanic species, and time of day. The species composition was most closely related to that of the Campeche Bank and oceanic Caribbean waters. Dominance of oceanic medusae within the reef lagoon was attributed to the narrowness of the continental shelf and the mesoscale hydrological features of the zone

Language and translation practices of Spanish-language newspapers published in the U.S. borderlands between 1808 and 1930

This article examines the impact of the anglicizing language policies implemented after the annexation of the U.S. borderlands to the United States on language use by describing the language and translation practices of Spanish-language newspapers published in the U.S. borderlands across different sociohistorical periods from 1808 to 1930. Sixty Hispanic-American newspapers (374 issues) from 1808 to 1980 were selected for analysis. Despite aggressive anglicizing legislation that caused a societal shift of language use from Spanish into English in most borderland states after the annexation, the current study suggests that the newspapers resisted assimilation by adhering to the Spanish language in the creation of original content and in translation

A remarkable teratological specimen of \u3ci\u3eTrichiotinus rufobrunneus\u3c/i\u3e (Casey) (Coleoptera: Scarabaeidae: Cetoniinae: Trichiini)

An unusual eye malformation observed in Trichiotinus rufobrunneus (Casey) (Coleoptera: Scarabaeidae: Cetoniinae: Trichiini), is described and illustrated. The functionality of the ectopic compound eye is discussed. According to label data, larval association with oak rotten log habitats is reported. Se describe e ilustra una malformación inusual en los ojos de Trichiotinus rufobrunneus (Casey, 1914). Se discute la funcionalidad de los ojos compuestos ectópicos. De acuerdo con los datos de etiqueta, se reporta la asociación de la larva con madera de roble en descomposición

Optimal Harvesting Time in Aquaculture Assuming Nonlinear Size-Heterogeneous Growth

This study explores the optimal harvesting time in a size-heterogeneous population dynamics. The model includes the effect of population density in both the mortality rate and individual growth. An application to specific conditions of shrimp culture in Mexico is presented. The optimal harvesting rule is numerically found for different economic and productive scenarios. Parallel results are also obtained under the hypothesis of homogeneous population growth, which has been traditionally considered in the economic literature. In general, the discounted net revenue of the firm is underestimated if the size-heterogeneity phenomenon is not taken into account, while the calculated harvesting time shortens the predictions based on the homogeneous growth hypothesis. These results reveal that optimal management rules are significantly mistaken if the size-heterogeneity phenomenon is not taken into account.Keywords: Aquaculture, Aquaculture Efficiency and Management, Fisheries Economic

Littlestock Brook natural flood management pilot: hydrological and water quality monitoring and analysis report

The Littlestock Brook Natural Flood Management (NFM) trial was a pilot project that ran from 2016 to 2022. Key objectives were to reduce flood risk to Milton-under-Wychwood and enhance the river environment. Through partnership working the Environment Agency collaborated with Wild Oxfordshire, the Evenlode Catchment Partnership, Bruern Estate and the local community to deliver NFM measures. UKCEH has undertaken a detailed monitoring campaign to assess the effectiveness of the measures on reducing flood flows and improving water quality. This report describes the monitoring network, observational methods, equipment adopted, the data processing and analysis undertaken
