Antimicrobial Residues in a Key Cerrado River: Distribution, Persistence, and Effects on Zebrafish Embryo‐Larval Development

Environmental Toxicology, EarlyView.
ABSTRACT The current study aimed to quantify the antimicrobials amoxicillin (AMX), cefazolin (CFZ), chloramphenicol (CHL), metronidazole (MTZ), and sulfamethoxazole (SX) in effluents and surface water of an important Cerrado river, calculate their half‐lives, and analyze their ecotoxicity following single and combined exposures.

Updates on Breeding Success and Conservation Challenges for White‐Rumped Vulture (Gyps bengalensis) in Rampur Valley, Nepal 尼泊尔兰普尔山谷白腰兀鹫繁殖成功研究进展及其保护挑战

Wildlife Letters, EarlyView.
This study investigates the breeding success of the critically endangered White‐rumped Vulture in Khaireni Community Forest, and examines local knowledge and perceptions toward its conservation. We found that 71% of active nests were successful, with breeding success significantly influenced by the proximity to carcass deposition sites.

Hurricane Disturbance and Tropical Tree Species Diversity

Science, 2000
The debate over the maintenance of high diversity of tree species in tropical forests centers on the role of tree-fall gaps as a primary source of disturbance. Using a 10-year data series accumulated since Hurricane Joan struck the Caribbean coast of Nicaragua in 1988, we examined the pattern of species accumulation over time and with increased ...

Isoprene emission from tropical tree species

Environmental Pollution, 2005
Foliar emission of isoprene was measured in nine commonly growing tree species of Delhi, India. Dynamic flow enclosure technique was used and gas samples were collected onto Tenax-GC/Carboseive cartridges, which were then attached to the sample injection system in the gas chromatograph (GC).

A Recount of Tropical Tree Species

Science, 2010
If aliens visited earth, perhaps they would wonder how many distinct life forms our planet has. With their advanced intellect and technology, they might well have the answer. It is clear from R. M. May's Perspective “Tropical arthropod species, more or less?” (2 July, p. [41][1]) that we do not.

MICROPROPAGATION OF TROPICAL TREE SPECIES

Acta Horticulturae, 2013
Tree species are important in tropical regions as a source of timber, nutrition, medicine, fuel, income and livestock food. Many vegetable species are not adapted to production in tropical climates, further highlighting the importance of tropical fruit species in these regions.

Towards quantifying tropical tree species richness in tropical forests

International Journal of Remote Sensing, 2009
This letter reports tests of whether the normalized difference vegetation index (NDVI) from Landsat Enhanced Thematic Mapper Plus (ETM+) and radar backscatter (C-, L-and P-bands) from Airborne Synthetic Aperture Radar (AIRSAR) imagery can be used to estimate tree species richness from 25 1-ha plots within continuous lowland forest types (dry, moist ...

Tropical tree species differ in damage and mortality from lightning

Nature Plants, 2022
Lightning is an important agent of mortality for large tropical trees with implications for tree demography and forest carbon budgets. We evaluated interspecific differences in susceptibility to lightning damage using a unique dataset of systematically located lightning strikes in central Panama. We measured differences in mortality among trees damaged
