Previous work (Newmeyer and Taylor 1967) showed that a nontandem duplication, Dp(IL-->IR)H4250, is regularly produced by recombination in crosses heterozygous for the effectively terminal pericentric inversion In(IL-->IR)H4250. The duplications initially have strongly inhibited growth because they are heterozygous for mating type, which behaves like a vegetative-incompatibility (het) locus. Suc...

LULC factors in Tikrit city (Iraq) and the neighboring municipalities are studied among 1989, 2002 2015 using various techniques of remote sensing, geographical information system (GIS), fuzzy analytical hierarchy process (FAHP). Satellite imagery with GIS helped to assess standard changes long term period. FAHP permitted estimating importance by determination suitable weight for used then prod...

The increasing population, depletion of natural resources, semi-arid climatic and poor soil health conditions in Jhajjar district Haryana have drawn major attention towards the changes Land Use/Land Cover (LULC). region's population is mainly dependent upon agrarian economy; thus, sustainable agricultural production a thrust area research. present study analyses LULC during two decades 2000 – 2...

Mitigating the negative impacts of declining worldwide forest cover remains a significant socio-ecological challenge, due to the dominant role of human decision-making. Here we use a Markov chain model of land-use dynamics to examine the impact of governance on forest cover in a region. Each land parcel can be either forested or barren (deforested), and landowners decide whether to deforest the...

Quantifying the temporal and spatial changes due to watershed interventions is important for assessing effectiveness of natural resource management practices on vegetative cover sediment management. This study assessed performance in a target site (Aba Gerima) compared collateral impacts neighbouring watersheds Ethiopia terms land-use land-cover change. Changes extent cropland, grassland shrubl...

We examine Land Use Cover Change (LULCC) in the Dedza and Ntcheu districts of Central Malawi model anthropogenic environmental drivers. present an integrative approach to understanding heterogenous landscape interactions short- long-term shocks how they inform future land management policy Malawi. Landsat 30-m satellite imagery for 2001, 2009, 2019 was used identify quantify LULCC outcomes base...

BACKGROUND Zika virus (ZIKV; genus Flavivirus, family Flaviviridae) is maintained in a zoonotic cycle between arboreal Aedes spp. mosquitoes and nonhuman primates in African and Asian forests. Spillover into humans has been documented in both regions and the virus is currently responsible for a large outbreak in French Polynesia. ZIKV amplifications are frequent in southeastern Senegal but litt...

Generally unseen and infrequently measured, submarine groundwater discharge (SGD) can transport potentially large loads of nutrients and other land-based contaminants to coastal ecosystems. To examine this linkage we employed algal bioassays, benthic community analysis, and geochemical methods to examine water quality and community parameters of nearshore reefs adjacent to a variety of potentia...
