Primera cita del pez Indo-Pacífico Terapon jarbua (Osteichthyes: Terapontidae) en el Mediterráneo con comentarios sobre la amplia distribución de esta especie

The Indo-Pacific fish Terapon jarbua is recorded for the first time in the Mediterranean. This record is evidentially the result of T. jarbua entering the Mediterranean via the Suez Canal (Lessepsian migration). The present record increases the total number of known Lessepsian fish to 74. A comparison of Mediterranean and Red Sea specimens of T. jarbua with specimens from the Far East suggests the necessity for genetic studies in order to clarify the unity of this taxon.El pez indo-pacífico Terapon jarbua se ha recolectado por primera vez en el Mediterráneo. Este registro es evidentemente el resultado de la entrada de T. jarbua en el Mediterráneo vía el Canal de Suez (migración Lessepsiana). El presenta registro incrementa el número total de peces Lessepsianos a 74. La comparación de especímenes de T. jarbua mediterráneos y del mar Rojo de los de zona lejanas del Este sugiere la necesidad de estudios genéticos para poder clarificar la unidad de este taxon

Arnoglossus nigrofilamentosus n. sp., una nueva especie de platija (Teleostei: Bothidae) de las costas mediterráneas de Israel, probablemente un nuevo caso de migración lessepsiana

The filamentous flounder Arnoglossus nigrofilamentosus n. sp. is described from four specimens collected in the southeastern Mediterranean near Tel-Aviv, Israel on 5 May 2017. The new species is characterized as follows: second to sixth dorsal-fin rays elongate and filamentous, dorsal-fin rays 78-84, anal-fin rays 61-66, pectoral-fin rays on ocular side 12-13, on blind side 7-9, caudal-fin rays iii,11,iii , lateral-line scales 52-54, gill rakers 0 + 4-5, not serrated, interorbital a narrow bony ridge without scales in the middle, interorbital width 11% to 16% of upper orbit diameter, no enlarged teeth anteriorly in upper jaw, and prevomer small, not enlarged, weakly projecting into mouth cavity; body in fresh specimens pale (may have been dark before the epidermis was abrased), head, peritoneum and vertical fins black. The new species is described and compared with similar species. Though the species has not yet been observed in the northern Red Sea, it probably originates from the Gulf of Suez, so this finding represents a probable new case of Lessepsian migration.Se describe una nueva especie de platija filamentosa Arnoglossus nigrofilamentosus n. sp. A partir de 4 ejemplares capturados en el SE Mediterráneo cerca de Tel-Aviv, Israel, el 5 de mayo del 2017. La nueva especie se caracteriza por los radios dorsales 2 a 6, largos y filamentosos, 78-84 radios dorsales, 61-66 radios anales, 12-13 radios pectorales en el lado ocular y 7-9 en el lado ciego, iii+11+iii radios caudales, linea lateral con 52-54 escamas, 0+4-5 arcos branquiales, no serrados, una estrecha cresta interorbital, sin escamas en medio, anchura interorbitaria 11-16% el diámetro superior de la órbita, mandibular superior sin dientes alargados anteriormente, y prevomer pequeño, no alargado, débilmente proyectado en la cavidad bucal. En ejemplares frescos, el cuerpo es pálido (quizás oscuro antes de la abrasion de la piel durante la pesca), cabeza, peritoneo y aletas verticales negras. Se describe la nueva especie y se compara con especies próximas. Aunque la especie no se ha observado todavía en el Mar Rojo, probablemente es originaria del Golfo de Suez, lo que supondría un nuevo caso de migración lessepsiana

High-throughput data analysis in behavior genetics

In recent years, a growing need has arisen in different fields for the development of computational systems for automated analysis of large amounts of data (high-throughput). Dealing with nonstandard noise structure and outliers, that could have been detected and corrected in manual analysis, must now be built into the system with the aid of robust methods. We discuss such problems and present insights and solutions in the context of behavior genetics, where data consists of a time series of locations of a mouse in a circular arena. In order to estimate the location, velocity and acceleration of the mouse, and identify stops, we use a nonstandard mix of robust and resistant methods: LOWESS and repeated running median. In addition, we argue that protection against small deviations from experimental protocols can be handled automatically using statistical methods. In our case, it is of biological interest to measure a rodent's distance from the arena's wall, but this measure is corrupted if the arena is not a perfect circle, as required in the protocol. The problem is addressed by estimating robustly the actual boundary of the arena and its center using a nonparametric regression quantile of the behavioral data, with the aid of a fast algorithm developed for that purpose.Comment: Published in at http://dx.doi.org/10.1214/09-AOAS304 the Annals of Applied Statistics (http://www.imstat.org/aoas/) by the Institute of Mathematical Statistics (http://www.imstat.org

Dynamic management for business processes modeling & execution in workflows

Contemporary workflow-management systems cannot represent change or evolution of business processes. When a change is needed due to external reason, an offline procedure is invoked in order to create a new workflow engine template for the future instances in the workflow enactment module. The standard interfaces do not deal with the business process metadata in a way that can actually change it as a reaction to inbound knowledge. There are many relevant cases, especially in the virtual enterprise arena, where the business process is not deterministic and is influenced by external parameters (such as the selection of virtual partners), so the knowledge of what should be done is available, however it is external to the system. There is a need to develop a modeling mechanism that enables to transfer process definitions in an automatic way, without the need for human interference. One way of confronting with these issues is the use of a rule-based engine to monitor business process execution. This engine will contain internal meta-rules that refer to metadata entities, i.e. rules that describe how to act on other rules (business process routing) when a change is detected, while executing all needed consistency checks

The Indian scad (Decapterus russelli), (Osteichtyes: Carangidae), a new Indo-Pacific fish invader of the eastern Mediterranean

The Indian scad, Decapterus russelli, is recorded for the first time from the Mediterranean. The presence of this Indo-Pacific species on the Mediterranean coast of Israel is evidently due to migration from the Red Sea via the Suez Canal. The collection of six specimens in the Mediterranean suggests that this species is well established in the Levant.La macarela índica, Decapterus russelli, se recolectó por primera vez en el Mediterráneo. La presencia de especies Indo-Pacíficas en la costa Mediterránea de Israel se debe evidentemente a migración desde el mar Rojo vía el Canal de Suez. La captura de seis especimenes en el Mediterráneo sugiere que esta especie está bien establecida en el Levant

Comparison of morphomeristical variations of Mediterranean and Red Sea populations of the Suez Canal migrant Sargocentron rubrum

Nine morphomeristical characters of squirrelfish, Sargocentron rubrum (Forsskal 1775) were compared between Mediterranean and Red Sea populations to examine changes caused by different environments. The significantly lower number of lateral line scales and vertebrae in the Mediterranean fishes is attributed to the higher temperature during the spawning season. The significant difference of the proportion of suborbital spinulation and the shape of the anterior tip of the nasal bone is inferred to be due to a founder effect. No significant difference was found in the relationship between eye diameter and preopercular spine length and standard length, nor in the number of dorsal and anal rays and nostril spinulation.peer-reviewe
