Genetic diversity of Iberian populations ofBemisia tabaci(Hemiptera: Aleyrodidae) based on random amplified polymorphic DNA-polymerase chain reaction
2001
The genetic structure of six Iberian populations of the whitefly Bemisia tabaci, two of them biotype Q, one biotype B, and the other three a mixture of both, has been studied using random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR). A total of 336 individuals was completely discriminated by means of 234 scored bands. Separate analyses of molecular variance of haploid males and diploid females using the pairwise number of differences between haplotypes showed that biotypes contribute significantly more to the observed variability than populations within biotypes. On average, gene flow between two biotypes of the same population is lower than between populations of identica…

High rates of short-term dynamics of forest ecosystem services
2021
Currently, the main tools for assessing and managing ecosystem services at large scales are maps providing snapshots of their potential supply. However, many ecosystems change over short timescales; thus, such maps soon become inaccurate. Here we show high rates of short-term dynamics of three key forest ecosystem services: wood production, bilberry production and topsoil carbon storage. Almost 85% of the coldspots and 65% of the hotspots for these services had changed into a different state over a ten-year period. Wood production showed higher rates of short-term dynamics than bilberry production and carbon storage. The high rates of dynamics mean that static snapshot ecosystem service map…
High boreal forest multifunctionality requires continuous cover forestry as a dominant management
2021
Intensive extraction of forest resources lowers biodiversity and endangers the functioning of forest ecosystems. As such, alternative management regimes have emerged, aspiring to promote forest biodiversity and nature protection in managed forests. Among them, continuous cover forestry, (i.e. selective logging), has received considerable attention and is being promoted by some researchers and NGOs. Yet, the full consequences of banning clear-cuts (i.e. rotation forestry) and replacing it entirely with continuous cover forest remains uncertain. We explore how restricting forest management alternatives (either rotation forestry or continuous cover forestry) will affect landscape-scale forest …
Review of the genus Prolactistes (Heteroptera: Cydnidae), with two new combinations, first Indonesian records and a key to species of the genus
2020
Two species of the genus ParaethusJ. A. Lis, 1994 (Hemiptera: Heteroptera: Cydnidae: Cydninae: Geotomini) are transferred to ProlactistesJ. A. Lis, 2001, resulting in the following new combinations: Prolactistes jani(J. A. Lis, 1995), comb. nov., and Prolactistes lisi(Magnien, 2014), comb. nov. Diagnostic characters for Prolactistes, and a key for its three species are provided. The present note also reports the first Indonesian record for Prolactistes australisJ. A. Lis, 2001 (Ambon Island, Timor) and P. lisi(Ambon Island), both known previously only from Australia.
A Multi-Criteria Decision Support System for Strategic Planning at the Swiss Forest Enterprise Level: Coping With Climate Change and Shifting Demands…
2021
Sustainable forest management plays a key role for forest biodiversity and the provisioning of ecosystem services (BES), including the important service of carbon sequestration for climate change mitigation. Forest managers, however, find themselves in the increasingly complex planning situation to balance the often conflicting demands in BES. To cope with this situation, a prototype of a decision support system (DSS) for strategic (long-term) planning at the forest enterprise level was developed in the present project. The DSS was applied at three case study enterprises (CSEs) in Northern Switzerland, two lowland and one higher-elevation enterprise, for a 50-year time horizon (2010 to 2060…
Global distributions of diazotrophs abundance and biomass - Depth integrated values computed from a collection of source datasets - Contribution to t…
2013
The MAREDAT atlas covers 11 types of plankton, ranging in size from bacteria to jellyfish. Together, these plankton groups determine the health and productivity of the global ocean and play a vital role in the global carbon cycle. Working within a uniform and consistent spatial and depth grid (map) of the global ocean, the researchers compiled thousands and tens of thousands of data points to identify regions of plankton abundance and scarcity as well as areas of data abundance and scarcity. At many of the grid points, the MAREDAT team accomplished the difficult conversion from abundance (numbers of organisms) to biomass (carbon mass of organisms). The MAREDAT atlas provides an unprecedente…

Two Host Clades, Two Bacterial Arsenals: Evolution through Gene Losses in Facultative Endosymbionts.
2015
International audience; Bacterial endosymbiosis is an important evolutionary process in insects, which can harbor both obligate and facultative symbionts. The evolution of these symbionts is driven by evolutionary convergence, and they exhibit among the tiniest genomes in prokaryotes. The large host spectrum of facultative symbionts and the high diversity of strategies they use to infect new hosts probably impact the evolution of their genome and explain why they undergo less severe genomic erosion than obligate symbionts. Candidatus Hamiltonella defensa is suitable for the investigation of the genomic evolution of facultative symbionts because the bacteria are engaged in specific relations…
Intervención terapéutica y coordinación familiar en los inicios comunicativos de un caso de atención temprana
2020
En este estudio de caso se aborda la intervención realizada en un centro de diagnóstico y atención temprana, a una alumna de dos años con hemiparesia lateral izquierda y dificultades en la manipulación y comunicación. Aplicando a lo largo de cuatro meses el sistema de Comunicación Total de Benson Schaeffer con el apoyo del método TEACCH, se pretende superar las graves limitaciones comunicativas de la alumna. El procedimiento metodológico utilizado es mixto y las técnicas de investigación empleadas son la aplicación de un test estandarizado, la entrevista, los registros de observación y el análisis documental. A partir del test cumplimentado por la madre que establece la evaluación inicial d…
