Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

Ecography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

The potential for flower nectar to allow mosquito to mosquito transmission of Francisella tularensis. [PDF]

PLoS ONE, 2017
Francisella tularensis is disseminated in nature by biting arthropods such as mosquitoes. The relationship between mosquitoes and F. tularensis in nature is highly ambiguous, due in part to the fact that mosquitoes have caused significant tularemia ...

Physicochemical Properties and Antioxidant Activity of Apocynum Honey in Different Regions of Xinjiang

Food Chemistry International, EarlyView.
ABSTRACT In this study, honey produced from Apocynum venetum L. was collected from BC (Bachu County), SY (Shaya County), and YL (Yuli County) in Xinjiang. The basic physical and chemical properties of the honey, and the contents of total phenols, total flavonoids, and amino acids were analyzed, and 16 types of polyphenols were quantified using triple ...

Draft genome of Rosenbergiella nectarea strain 8N4T provides insights into the potential role of this species in its plant host. [PDF]

, 2020
Background:Rosenbergiella nectarea strain 8N4T, the type species of the genus Rosenbergiella, was isolated from Amygdalus communis (almond) floral nectar. Other strains of this species were isolated from the floral nectar of Citrus paradisi (grapefruit),

Warming‐Mediated Decreases in Nectar Quality Translate Into Lower Energy Reserves of the Monarch Butterfly (Danaus plexippus)

Global Change Biology Communications, EarlyView.
Warming caused a significant decrease in monarch fat mass, likely due to an observed reduction in sucrose concentration caused by warming of the nectar. Since sucrose fuels fall migration and overwintering, our results suggest climate warming may reduce migration success and overwinter survival.

Morphological specialization influences nectar extraction efficiency of sympatric nectar-feeding bats [PDF]

Journal of Experimental Biology, 2012
SummaryMammals frequently use nectar as a supplementary food, while a predominantly nectarivorous lifestyle with morphological specializations for this feeding mode is rare within the class. However, Neotropical flower-visiting bats largely depend on nectar resources and show distinct adaptations to a nectar diet.

Functional Stability Despite Taxonomic Changes in Mixed‐Species Foraging Flock Participants Along an Elevational Gradient in Knuckles Montane Reserve, Sri Lanka 斯里兰卡纳克斯山地保护区 (Knuckles Montane Reserve) 海拔梯度上混合物种觅食群参与者的功能稳定性与分类变化

Integrative Conservation, EarlyView.
This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

Garden varieties: how attractive are recommended garden plants to butterflies? [PDF]

, 2015
One way the public can engage in insect conservation is through wildlife gardening, including the growing of insect-friendly flowers as sources of nectar. However, plant varieties differ in the types of insects they attract.
