Abstract The paper focuses on research improving the water supply of drainage systems humid areas in context anthropogenic climate change. aim is to elaborate ways for increasing available and restoring active regulation reclaimed lands a changing climate. Reclaimed are main factor sustainable agricultural production Ukraine guarantors its stability. area drained about 3.2 million hectares, inc...
A new species of Chydoridae cladoceran (Crustacea: Cladocera: Chydoridae) is described from the Cerrado (a Brazilian tropical savanna ecoregion), Central Brazil. Ephemeroporus quasimodo sp. nov. differs from other species of the genus in a high dorsal keel on carapace and posterior part of the head shield, which resembles a hunchback. Parthenogenetic females, ephippial females and males are des...
A total of 12 gnat species are reported for the first time from Finland (3 Cecidomyiidae, 1 Keroplatidae, 8 Mycetophilidae), and the occurrence of Macroceranigropicea Lundström in Finland is verified. All material was collected from the Finnish Lapland, mainly from the north boreal ecoregion. Two of the recorded species are likely to be pyrophilous, associated with forest fire sites. A photo of...
Species distribution models (SDMs) have been widely employed to evaluate species–environment relationships. However, when extrapolated over broad spatial scales or through time, these decline in their predictive ability due variation how species respond environment. Many assume relationships remain constant space and hindering accurately forecast distributions. Therefore, there is growing recog...

Cynomops planirostris (Peters, 1866) was previously known in Argentina only from the provinces of Salta and Jujuy northwest Misiones northeast. Here, we newly report this species province Corrientes Humid Chaco ecoregion. We also offer information on natural history bat assemblage present study area. This record increases number bats to 34.
Dryland net primary productivity (NPP) is sensitive to temporal variation in precipitation (PPT), but the magnitude of this ‘temporal sensitivity’ varies spatially. Hypotheses for spatial sensitivity have often emphasized abiotic factors, such as moisture limitation, while overlooking biotic vegetation structure. We tested these hypotheses using spatiotemporal models fit remote-sensing data set...
A Brazilian Porcupine, Coendou prehensilis (Linnaeus, 1758), was encountered and photographed at night on a recently cleared forest path in Presidente Hayes Department, Paraguay. Although C. is widespread has been reported from variety of ecoregions habitats, this record western Paraguay the first South American Humid Chaco ecoregion.
