Mate-searching behavior in the invasive German wasp, Vespula germanica, in Patagonia por Martinez Von Ellrich, Andres, Masciocchi, Maite, Pisman, Natalia, Villacide, Jose Maria, Corley, Juan Carlos

“…In tethered flight assays, we established contrasting flight patterns in females and males that may partly explain how related individuals distribute spatially during the mating period. We also determined experimentally, in the field and in the laboratory via olfactometer assays, that gynes produce airborne pheromonal cues that attract drones and are important during mate location. …”

A review of the use of Near-Infrared Hyperspectral Imaging (NIR-HSI) techniques for the non-destructive quality assessment of root and tuber crops por Adesokan, M., Alamu, E.O., Otegbayo, B., Maziya-Dixon, B.

“…Hyperspectral imaging technology, which combines spectroscopy and imaging principles, has an advantage over conventional spectroscopy due to its ability to simultaneously evaluate the physical characteristics and chemical components of various food products and specify their spatial distributions. HSI has demonstrated significant potential for obtaining quick information regarding the chemical composition of the root and tuber, such as starch, protein, dry matter, amylose, and soluble sugars, as well as physical characteristics such as textural properties and water binding capacity. …”

Estimating multidimensional development resilience por Lee, Seungmin, Abay, Kibrom A., Barrett, Christopher B., Hoddinott, John F.

“…Univariate resilience measures constructed using consumption expenditure, dietary diversity and livestock asset holdings show distinct temporal and spatial distributional patterns. But while univariate measures are weakly correlated with one another and with different well-being metrics, multivariate measures exhibit much stronger rank correlations. …”

Sub-catchment level assessment of bench terrace impacts on runoff and erosion for upscaling in northern Tunisia. por Khelifa, Walid Ben, Hermassi, Taoufik, Strohmeier, Stefan, Habaieb, Hamadi

“…In the present study, Soil and Water Assessment Tool (SWAT) was used to investigate the spatially distributed effects of bench terraces and small reservoirs, so called hill lakes, by means of 1) calibration of a small-scale and homogenously treated sub-catchment (Sbaihia sub-catchment; 3.2 km2) and 2) up-scaling (Rmel watershed; 675 km2). …”

Mapping the irrigated rice cropping patterns of the Mekong delta, Vietnam, through hyper-temporal SPOT NDVI image analysis por Nguyen, T.T.H., Bie, C.A.J.M. de, Ali, A., Smaling, E.M.A., Hoanh, Chu Thai

“…Using the collected information of 112 farmers' fields belonging to the 26 selected classes, the map produced provides highly accurate information on rice cropping patterns (94% overall accuracy, 0.93 Kappa coefficient). We found that the spatial distributions of the triple and the double rice cropping systems are highly related to the flooding regime from the Hau and Tien rivers. …”

Structure and tree diversity of lowland limestone forest on Seram Island, Indonesia por Ranlund, Åsa

“…As one of few studies on limestone forest in Malesia this is also an example of what tree species might occur there. The distributions of tree species found in the study, based on a small sample, varied; some species have distributions towards New Guinea and Australia, others have Western distributions and some are restricted to the near region.…”

Combining remotely sensed surface energy fluxes and GIS analysis of groundwater parameters for irrigation system assessment por Alexandridis, T.K., Panagopoulos, A., Galanis, G., Alexiou, I., Cherif, I., Chemin, Yann H., Stavrinos, E., Bilas, G., Zalidis, G.C.

“…Despite being necessary for effective water management, the assessment of an irrigation system requires a large amount of input data for the estimation of related parameters and indicators, which are seldom measured in a regular and reliable manner. In this work, spatially distributed surface energy balance fluxes and geographical information systems analysis of multiple groundwater parameters were used to estimate water availability, supply, and demand, in order to calculate water-accounting indicators. …”
