African forest elephants are really slow breeders

In this post, Associate Editor Johan du Toit discusses new Policy Direction “Slow intrinsic growth rate in forest elephants indicates recovery from poaching will require decades” by Andrea Turkalo, Peter Wrege, and George Wittemyer, published today. Intrinsic population growth is related to body mass The rate at which a population grows (r) under ideal conditions with no resource limitation, disease, or predation, is governed by … Continue reading African forest elephants are really slow breeders

Hunting and hiking are not so bad for wildlife populations

In this post Roland Kays discusses his paper ‘Does recreation or hunting affect wildlife communities in protected areas?‘ published today in Journal of Applied Ecology. Public wild lands have dual mandates to protect animals and provide recreational opportunities for people. These goals could be at odds if recreation, ranging from quiet hiking to legal hunting and trapping, hurts the wildlife community.  Past studies have clearly … Continue reading Hunting and hiking are not so bad for wildlife populations

The ecology behind mosquito–Wolbachia interactions: implications for a novel strategy for biocontrol of arboviruses

In this post Penelope Hancock discusses her paper ‘Density-dependent population dynamics in Aedes aegypti slow the spread of wMel Wolbachia‘ published in Issue 53:3 today. Aedes aegypti mosquitoes, the primary vector of dengue and zika, are the current target of a novel biocontrol strategy involving Wolbachia bacteria. Mosquitoes infected with Wolbachia are less able to transmit viruses to humans. Releases of Wolbachia bacteria into field … Continue reading The ecology behind mosquito–Wolbachia interactions: implications for a novel strategy for biocontrol of arboviruses

New spatio-temporal model improves the ability of fishery managers to set sustainable catch limits

In this post Associate Editor Andre Punt discusses a paper he recently handled by James T. Thorson, Jason Jannot and Kayleigh Somers ‘Using spatio-temporal models of population growth and movement to monitor overlap between human impacts and fish populations‘ In many jurisdictions, including the U.S., conservation management of fish stocks involves comparing catches with estimates of an overfishing limit (OFL). The OFL is a catch … Continue reading New spatio-temporal model improves the ability of fishery managers to set sustainable catch limits

Engineering soil complexity

In this post Kirsty Lees discusses the recent paper from Alice Johnston and colleagues ‘Effects of agricultural management practices on earthworm populations and crop yield: validation and application of a mechanistic modelling approach’ Healthy soils are essential to the provision of ecosystem services; however, increasing intensification has resulted in soil degradation in many arable systems threatening water quality, carbon storage and ultimately food security. Any … Continue reading Engineering soil complexity

Eagles and power lines: the applied value of long-term data

In this post Associate Editor Jeroen Minderman discusses a paper he recently handled by Clément Chevallier and colleagues ‘Retrofitting of power lines effectively reduces mortality by electrocution in large birds: an example with the endangered Bonelli’s eagle’ I have spent much of the past few years studying the effects of wind turbines and wind farms on bird and bat populations, and as a result when … Continue reading Eagles and power lines: the applied value of long-term data

From economy to ecological management: Portfolio theory enlightens the performance of social-ecological systems

This guest post from David Angeler (@DGAngeler), Associate Editor for Journal of Applied Ecology on the paper “Performance of salmon fishery portfolios across western North America” by Jennifer Griffiths et al. (@JenAquatic @mark_scheuerell @SteveLindley831) Ecologists and managers are well aware of the reciprocal dependence of systems between people and nature. However, the linkages between social-ecological systems are complex and therefore difficult to measure. This limits … Continue reading From economy to ecological management: Portfolio theory enlightens the performance of social-ecological systems
