Occurrence and distribution of sarcoptic mange in wild Neotropical canids

Medical and Veterinary Entomology, EarlyView.
Sarcoptic mange affects most Neotropical canid species across multiple countries. It represents a widespread yet largely overlooked conservation threat with potential for cross‐species transmission. Coordinated monitoring and management efforts are needed to understand and mitigate its impacts. Abstract Sarcoptic mange, a contagious skin disease caused

Automated extraction of leaf mass per area from digitized herbarium specimens

New Phytologist, EarlyView.
Summary The digitization of vast herbarium collections has made millions of plant specimen images freely available online, which can now be used to generate phenotypic datasets of unprecedented scope. Here, we assess the potential of computer vision tools to automate the extraction of predicted leaf mass per area (LMApred) from digitized herbarium ...

Widespread forest-savanna coexistence but limited bistability at a landscape scale in Central Africa

Environmental Research Letters
Tropical forest and savanna frequently coexist under the same climatic conditions, which has led to the hypothesis that they could represent alternative ecosystem states, stabilized by internal feedbacks.

Bringing Fire Back: How Prescribed Fires Shape Ant Communities in a Fire-Suppressed Neotropical Savanna

Diversity
We evaluated the effects of different fire regimes on the ground-ant community from a savanna (Cerrado) reserve in southern Brazil, where a process of woody encroachment has been taking place. Ants are a dominant faunal group in tropical savannas.

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

Plant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

Not only reseeder or resprouter plants: Trait syndromes and post‐fire responses of three iconic Mediterranean woody species

Plant Biology, EarlyView.
Post‐fire plant functional strategies of Mediterranean woody species can be less fixed than often thought when intraspecific variability of fire‐related traits is considered. Abstract Fire can profoundly affect ecosystem dynamics, species distribution and plant traits, especially in open biomes.

Effects of Managed Disturbances on Plant Community Structure and Nutritional Function in the Tropical Savanna Habitat of the Endangered Eld’s Deer (Rucervus eldii)

Agronomy
Managed disturbances and their consequences for plant community structure, productivity, and foliar nutrients in the habitat of the endangered Eld’s deer remain inadequately characterized.

A climate‐sensitive tropical urbanism under extreme heat†

Singapore Journal of Tropical Geography, EarlyView.
Tropical urban dwellers face twin climate challenges that impinge on their quality of life: climate overheating and the urban heat island (UHI). The latter superimposed on the former to lead to high levels of thermal discomfort, carbon and energy consequences.
