Seasonal and long-term variability of phytoplankton in the Middle Caspian was studied based on remote sensing data sea by SeaWiFS MODIS-Aqua scanners 1998–2021 results field observations 2004–2021. The seasonal chlorophyll “a” (CHL) calculated from satellite using a regional algorithm indicated that autumn winter seasons were main production periods year. In summer, period stagnation observed g...

A TU M N 2 0 1 4 THIS EDITION OF THE CSAE NEWSLETTER PRESENTS research being undertaken as part of the Improving Institutions for Pro-poor Growth (IIG) research programme, funded by the UK Department for International Development. The current phase of the iiG studies the means by which firms and markets can foster growth and development. The programme is organized around a range of empirical re...

In northern Europe, replacing winter barley with winter wheat as the preceding crop for winter oilseed rape (Brassica napus L.; WOSR) often results in a delayed WOSR sowing and poor autumn growth. Based on data from a field experiment running in 2009/2010, 2010/2011, and 2012/2013, this study aims (i) to investigate how a delayed sowing method affects seed yield, N offtake with the seeds, and a...

A total of 1,496 rodents and insectivores were live-trapped at Yeoncheon-gun (n = 351), Paju-shi (804), and Pocheon-gun (343), Gyeonggi-do (Province), and examined for intestinal helminths, including Neodiplostomum seoulense, seasonally from December 2004 to September 2005. Six species of rodents, including Apodemus agrarius (1,366), Mus musculus (32), Micronytus fortis (28), Eothenomys regulus...

During 2004, four experiments were carried out, one each season, in order to determine the species composition and seasonal dynamics of Calliphoridae in a rural area of Córdoba (Argentina). Two pigs (Sus scrofa L.), weighing approximately 8 Kg each, were used in each experiment. They were killed with a blow to the head and immediately placed in a variant of the Schoenly et al. (1991) trap. One ...

The TROpospheric WAter RAdiometer (TROWARA) is a ground-based microwave radiometer with an additional infrared channel observing atmospheric water parameters in Bern, Switzerland. TROWARA measures with nearly all-weather capability during dayand nighttime with a high temporal resolution (about 10 s). Using the almost complete data set from 2004 to 2016, we derive and discuss the diurnal cycles ...

ISSN 1808-7035. The seasonal variability of the benthic community in a shallow sublittoral site was analyzed at the Laguna Estuarine System, a chocked lagoon in South Brazil. Seasonal replicate samples for t...

Hamilton and Brown suggested that bright autumn coloration in trees is an energetically expensive and therefore honest (handicap) signal of defensive commitment against insects. If this is so, one should expect that the intensity of the proposed signal should depend strongly on tree health. However, to the best of our knowledge, the link between vigour and autumn colour has never been tested. W...

Purpose: Increasing salt of water is a world-wide problem, heavy metals belonging to the most important matrials. The progress of industries has led to increased emission of pollutants and salt of water into ecosystems. Tajan is one of navigable river in the Northh of Iran. Along the Tajan agricultural industries units such as piping, steel, paint making, paper mill, fish cultivation, abbottior...

We investigated the distribution, photoproduction, microbial uptake, and air–sea exchange of carbon monoxide (CO), a key photoproduct of chromophoric dissolved organic matter (CDOM), in open waters of the southeastern Beaufort Sea in autumn 2003 and spring 2004. Diurnal cycles of surface water CO concentration ([CO]) occurred in autumn but not in spring. In both seasons [CO] was well above air-...
