The reasons for the resurgence of malaria in the African highlands have been subject of debate. Because vector abundance is important for malaria transmission, gaining a better understanding of vector biology is a key to understanding the mechanisms of highland malaria. We studied vector productivity in relation to the highland environment and compared productivity between lowland and highland ...

[1] Multiple end-member spectral mixture analysis (MESMA) was applied to the Clementine UVVIS global 1 km multispectral data set, and the resulting highland material fraction image was used to investigate highland contamination of mare surfaces by impact cratering. MESMA decomposes each pixel with the number of end-members fewer than the number of the spectral bands of Clementine UVVIS data. Th...

The present survey was carried out in Oak (Quercus brantii Lindl.) woodlands of Arghvan valley protected area, in Ilam province, western Iran. The main aim of this study was to survey the understory vegetation of oak in different classes of altitude (1400-1600, 1600-1800 and >1800 m) in the southern aspects, and their relationship with physical and chemical properties of soil. Four transects, w...

We analyze phylogenetic relationships among temperate, subtropical highland, and subtropical lowland species of the Drosophila takahashii and montium species subgroups based on sequence data of COI and Gpdh genes and discuss the evolution of temperate species in these subgroups with reference to their climatic adaptations. In the takahashii subgroup, D. lutescens (the temperate species) branche...

OBJECTIVE To examine the association between travel (recency of travel, transmission intensity at destination compared to origin and duration of travel) and confirmed malaria in Uganda. METHODS Health facility-based case-control study in highland (~2200 m), and highland fringe (~1500 m) areas with adjustment for other covariates. RESULTS In the highland site, patients who had travelled to a...

This chapter gives a brief analysis of basic factors influencing highland climates and peculiarities of atmospheric circulation caused by mountain systems. Special attention is paid to characteristics of highland climate which are manifested in regimes of temperature, precipitation, wind, solar radiation, etc. Typical and exclusive features of highland climates in different large-scale climatic...

Tropical highland regions are experiencing rapid climate change. In these regions the adaptation challenge is complicated by the fact that elevation contrasts and dissected topography produce diverse climatic conditions that are often accompanied by significant ecological and agricultural diversity within a relatively small region. Such is the case for the Choke Mountain watersheds, in the Blue...

This study aimed to quantify and map habitat quality in the Dire Legedadi watersheds between 1985 2022 using InVEST model. The purpose of this was assess spatiotemporal changes watersheds. result showed, 2022, both experienced a significant decline quality. extent high Legadadi watershed has decreased significantly from 206 km2 50.26 2022. Similarly, gradually declined 87.29 35.44 construction ...
