High survival promotes bunchgrass persistence in old‐growth savannas under different fire regimes

open access: yesEcosphere
Clonal perennial grasses are a key functional group in fire‐prone, old‐growth grasslands and savannas. They are flammable and can resist extinction for decades.

Underestimation of avian diversity in the Tumbesian hotspot: Sampling gaps and conservation challenges

open access: yesConservation Science and Practice, EarlyView.
This study provides the first comprehensive reassessment of avian diversity in the Tumbesian region in over 30 years, documenting 931 species and identifying significant sampling gaps driven by geographic accessibility. We reveal a critical misalignment between biodiversity value and current protection coverage, particularly in humid forests which ...

Effect of patches of woody vegetation on the role of fire in tropical grasslands and savannas

open access: yes, 2014
In tropical grasslands and savannas, fire is used to reduce woody vegetation expansion. Woody vegetation in these biomes is often patchily distributed, and micro-climatic conditions can largely vary locally with unknown consequences for fire effects.

Tolerance for jaguars among ranching communities in the Colombian Llanos

open access: yesConservation Science and Practice, EarlyView.
Livestock protection measures are often implemented with the desired outcome of reducing retaliatory killings. We studied drivers of retaliatory killings in four communities in the Colombian Llanos and evaluated whether an electric fencing intervention would improve tolerance for jaguars.

1173. Ipomoea pandurata (L.) G. Mey

open access: yesCurtis's Botanical Magazine, EarlyView.
Summary Ipomoea pandurata is a Morning Glory from North America which develops a large storage root. There is much uncertainty about its discovery before its formal description in the middle of the 18th century. Originally described as a Convolvulus, almost a hundred years passed before its recognition as a species of Ipomoea.

Amazonian savannas are an integral part of Brazil’s Amazon “biome”: implications for environmental policies

open access: yesDiscover Conservation
Conservation policies in Brazil differ between the “biomes” into which the country has divided its territory since 2004. The Amazon biome is predominantly tropical forest but also includes unique savanna ecosystems, while the Cerrado biome is composed of

Social bees can enhance the persistence of plant–bee interactions during seasonal changes in seasonally dry tropical forests

open access: yesEcological Entomology, EarlyView.
Social bees, especially Meliponini, formed a persistent core that maintained plant–bee interactions across both dry and green seasons in the Caatinga. Persistence was not linked to broader diets; social bees used fewer plant species, despite availability, indicating selective tracking of temporally concentrated floral resources.
