The Meladema Laporte, 1835 (Coleoptera, Dytiscidae) of the Sahara Desert
Meladema Laporte, 1835 is a genus of large diving beetles, found in the Western Palaearctic, from the Canary Islands and Madeira to western Turkey (Bilton & Ribera 2017). The genus currently contains four species: the widespread M. coriacea Laporte, 1835, distributed from the Canary Islands to Turkey and ranging from southern France and the central Balkans south to the central Sahara, two Atlantic Island endemics, M. imbricata (Wollaston, 1871) from the western Canary Islands and M. lanio (Fabricius, 1775) from the main island of Madeira, and a fourth, recently described species, M. lepidoptera Bilton & Ribera, 2017 from the Tyrrhenian Islands (Corsica, Sardinia, Elba, Montecristo) and parts of the Italian mainland (Bilton & Ribera 2017). </jats:p
Toward a New Understanding of Creative Dynamics: From One-Size-Fits-All Models to Multiple and Dynamic Forms of Creativity
This article proposes an alternative to a managerial best practice approach to creativity based on the notion of creativity as a singular concept. Our alternative draws on three fundamental ideas that are emerging in different pockets of the creativity literature in a way that can be readily conceptualized and applied in practice. The first idea is that creativity is really about creativities , or a cluster of different and discrete qualities that can be combined to suit the context in which they operate. The second is that creativity is not static: it is about creativitying , or the action and the practice of combining these creativities, which evolve over time. The third is that being creative in organizations is not an individual act: rather, it is the multiple activities of groups as they go about creativitying
The exotic weevil Stenopelmus rufinasus Gyllenhal, 1835 (Coleoptera: Curculionidae) across a "host-free" pond network
The presence of the exotic weevil Stenopelmus rufinasus (Coleoptera: Curculionidae) is closely related to the occurrence of
the exotic red water fern, Azolla filiculoides. In this paper, we present the first records of S. rufinasus in Doñana National
Park (SW Spain), based on sampling of macroinvertebrates in 91 temporary ponds, including monthly samples of 22 ponds,
during two successive years (2005-2007). The exotic weevil was present in 21% of the sampled ponds where the host plant, A.
filiculiodes, was not detectable. Because A. filiculoides can reach high densities in an adjacent area of marsh, we suggest that
the occurrence of the exotic weevil in these ponds is a consequence of dispersal from nearby marshes. Our study demonstrates
that S. rufinasus adults can occur at relatively high densities in ponds where the host plant is not present, suggesting that such
apparently “host-free” sites may act as stepping stones for the spread of this speciesLa presencia de la especie de gorgojo exótico Stenopelmus rufinasus (Coleoptera: Curculionidae) está íntimamente rela-
cionada con la planta acuática exótica Azolla filiculoides. En este estudio se registró por primera vez la presencia de S.
rufinasus en el Parque Nacional de Doñana (SO España) tras realizar un muestreo de macroinvertebrados en 91 lagunas
que incluye muestreos mensuales de 22 de las mismas durante dos años consecutivos (2005-2007). El gorgojo exótico estuvo
presente en el 21% de las lagunas muestreadas a pesar de que su supuesto hospedador, A. filiculiodes, no fue detectado.
Dado que A. filiculiodes puede alcanzar grandes densidades en la marisma adyacente, sugerimos que la presencia del gor-
gojo exótico en las lagunas temporales se debe a su dispersión desde la marisma. Este estudio demuestra que individuos
adultos de S. rufinasus pueden aparecer con densidades relativamente altas en lagunas donde su hospedador potencial no
está presente, lo que sugiere que estos sitios libres de hospedador podrían actuar como zonas de paso para la dispersión de
la especiePeer reviewe
