Fire is a globally important driver of ecosystem composition, structure and function

In fire-prone landscapes, appropriate fire management may help bring native mammals back from the brink of extinction. In a new paper, Shaw et al. use prescribed burning to understand how small mammal populations recover after fire, so that recovery mechanisms can be incorporated into management strategies. Fire plays a pivotal role in ecosystems around the world, influencing where species are found, their abundance in the … Continue reading Fire is a globally important driver of ecosystem composition, structure and function

Mikakati madhubuti ya kudhibiti Mathenge (Prosopis juliflora) yaonyesha mafanikio makubwa katika kuboresha maisha ya wananchi wa Kaunti ya Baringo, Kenya

This post is also available in English (here) and Amharic (here).   Mabadiliko ya tabia ya nchi, uharibifu wa mazingira na ueneaji wa mimea vamizi kama Mathenge (Kitaalamu Prosopis juliflora) ni tishio kubwa kwa upatikanaji endelevu wa kipato kwa jamii zinazoishi maeneo makame. Changamoto hizi pia zinaathiri mifumo ya kiikolojia katika kutoa huduma kama malisho kwa mifugo ambayo ni rasilimali muhimu kwa wafugaji na wakulima. … Continue reading Mikakati madhubuti ya kudhibiti Mathenge (Prosopis juliflora) yaonyesha mafanikio makubwa katika kuboresha maisha ya wananchi wa Kaunti ya Baringo, Kenya

Spatially explicit scenarios for management of an invasive woody weed in Baringo County, Kenya, reveal significant livelihood benefits

This post is also available in Amharic (here) and Swahili (here). A new study by Eschen and colleagues suggests that clearing the invasive woody weed, Prosopis julifora, and subsequently restoring this land into grassland may have significant financial benefits for local stakeholders and contribute to climate change mitigation in Baringo County, Kenya. Climate change, land degradation, and invasive alien species (IAS), such as Prosopis julifora, … Continue reading Spatially explicit scenarios for management of an invasive woody weed in Baringo County, Kenya, reveal significant livelihood benefits

Rethinking biodiversity conservation in cultural landscapes: land management interventions informed by biodiversity audits work

To address biodiversity declines within semi‐natural habitats, land management must cater for diverse taxonomic groups. Through one of the largest multi-taxa experiments yet attempted in a European grassland, Hawkes and colleagues show that interventions inspired by history and autecological knowledge enhance priority biodiversity. Conservationists have traditionally focused on the idea that ‘mimicking’ elements of history will support large numbers of species that benefit from human … Continue reading Rethinking biodiversity conservation in cultural landscapes: land management interventions informed by biodiversity audits work

Tropical riparian forests in danger from large savanna wildfires

In their latest research, Flores and colleagues combine satellite image analysis with detailed field assessments, to quantify the impact caused by large wildfires on riparian forests in the Chapada dos Veadeiros National Park (CVNP). Large savanna wildfires are increasing across the tropics because of a synergism between climate change and unsustainable management practices. In Brazil, for instance, savannas of the Cerrado and Pantanal have recently … Continue reading Tropical riparian forests in danger from large savanna wildfires

Investigating the effects of fire management on savanna biodiversity with grid‐based spatially explicit population simulations

The development of effective fire management regimes is a global challenge. New research from Davies and colleagues aims to develop a flexible modelling approach to investigate how the spatiotemporal application of fire influences savanna biodiversity. Despite the integral role that fire plays in the functioning of ecosystems around the world, there remain few areas where the occurrence of fire has not been disrupted, in some … Continue reading Investigating the effects of fire management on savanna biodiversity with grid‐based spatially explicit population simulations

Weathering the storm: plant community flood resilience in intensively managed grasslands and the role of the plant economic spectrum

As flooding events increase in frequency and severity, how will managed grasslands weather the storm? Can we use the traits or ‘strategies’ of the plants that make up these grasslands to predict their resilience? Natalie Oram and colleagues address this issue in their new Journal of Applied Ecology article. Here they discuss their work further. Long story short: in flooded conditions, resource-conservative plant communities are … Continue reading Weathering the storm: plant community flood resilience in intensively managed grasslands and the role of the plant economic spectrum

Age is a better indicator of biodiversity for road verges than surrounding landscape

In their recently published article, Alistair Auffret and Evelina Lindgren show how historical maps can be a useful tool to identify which road verges can best support grassland habitats. Here the authors provide a summary of their work Road verges are by now quite well known to provide valuable habitat for grassland species if they are managed appropriately (Phillips et al., 2019; Vanneste et al., … Continue reading Age is a better indicator of biodiversity for road verges than surrounding landscape

Conservando flores conservamos polinizadores?

An English version of this post is available here. La mayoría de los esfuerzos para promover la conservación de polinizadores están enfocados en mantener o incrementar el rango de plantas con flores disponibles para ellos. La razón es simple: las plantas con flores proveen néctar y polen, recursos esenciales para su subsistencia. Sin embargo, los polinizadores dependen de otros recursos que probablemente también determinan su … Continue reading Conservando flores conservamos polinizadores?
