When tropical and subtropical congeners met: Multiple ancient hybridization events within Eriobotrya in the Yunnan‐Guizhou Plateau, a tropical‐subtropical transition area in China [PDF]

open access: greenMolecular Ecology, 2021
Global climate changes during the Miocene may have created ample opportunities for hybridization between members of tropical and subtropical biomes at the boundary between these zones. Yet, very few studies have explored this possibility.

The Relationship between Tropical Cyclone Rainfall Area and Environmental Conditions over the Subtropical Oceans [PDF]

open access: bronzeJournal of Climate, 2018
In this study, the variation of tropical cyclone (TC) rainfall area over the subtropical oceans is investigated using the Tropical Rainfall Measuring Mission precipitation data collected from 1998 to 2014, with a focus on its relationship with environmental conditions. In the subtropics, higher moving speed and larger vertical wind shear significantly

Serological Survey of Hantavirus in Inhabitants from Tropical and Subtropical Areas of Brazil [PDF]

open access: goldAdvances in Virology, 2016
Brazil has reported more than 1,600 cases of hantavirus cardiopulmonary syndrome (HPS) since 1993, with a 39% rate of reported fatalities. Using a recombinant nucleocapsid protein ofAraraquaravirus, we performed ELISA to detect IgG antibodies against hantavirus in human sera.

Models of Duricrust Formation in Tropical and Subtropical Areas

open access: gold, 2022
<div>Ferruginous duricrust formation takes place by dissolution and accumulation of iron during the wet season and precipitation during the dry season. However, the formation of iron duricrusts has always been the centre of much debate. They commonly form as hard iron layers in tropical and subtropical environments with strong climatic ...

Deforestation leakage undermines conservation value of tropical and subtropical forest protected areas [PDF]

open access: hybridGlobal Ecology and Biogeography, 2020
AbstractAimThe establishment of protected areas is among the most widespread responses to mitigate species loss. Although protected areas are often assumed to have conservation benefits, negative impacts have also been documented. One potential negative outcome is leakage, whereby protected areas displace land‐use activities harmful to conservation ...

Comparing Models for Duricrust Formation in Tropical and Subtropical Areas

open access: gold, 2023
Duricrusts are hard elemental layers forming in tropical and subtropical regions. Different types of duricrusts exist, including calcretes, silcretes and ferricretes (or iron duricrusts), that differ by their composition and, most likely, their formation mechanism.

The Impact of the Green Revolution on Plant Protection in Tropical and Subtropical Areas [PDF]

open access: bronzeBulletin of the Entomological Society of America, 1972
The earliest use of the term “integrated control,” at least in its pest control sense, dates from June of 1954 (Smith and Allen, 1954). Thus, the history of integrated control would appear to have spanned little more than 17 years. Until now, most discussions of the origins of integrated control have emphasized the over-dependence on and the over-use ...

Scoring systems for prediction of malaria and dengue fever in non-endemic areas among travellers arriving from tropical and subtropical areas [PDF]

open access: hybridEmergency Medicine Journal
BackgroundFever is a common symptom among travellers returning from tropical/subtropical areas to Europe, and promptly distinguishing severe illnesses from self-limiting febrile syndromes is important but can be challenging due to non-specific clinical presentation.MethodsA cross-sectional study enrolled adults and children who sought care during 2015 ...

Incidence of respiratory viruses among travelers with a febrile syndrome returning from tropical and subtropical areas [PDF]

open access: bronzeJournal of Medical Virology, 2008
AbstractFifty million people are estimated to travel from industrial countries to the tropics annually. In spite of exhaustive studies and widely different diagnosis among returned patients, some cases of febrile illnesses remain without an etiological diagnosis, suggesting that these cases could be due to viral respiratory tract infections.

Stalagmite water content as a proxy for drip water supply in tropical and subtropical areas

open access: gold, 2012
. In this pilot study water was extracted from samples of two Holocene stalagmites from Socotra Island, Yemen, and one Eemian stalagmite from southern continental Yemen. The amount of water extracted per unit mass of stalagmite rock, termed "water yield"
