Early warning indicators in aquatic ecosystems

In this post Craig Allen and Hannah Birge discuss a paper from Sarah Burthe and colleagues ‘Do early warning indicators consistently predict nonlinear change in long-term ecological data?’ Complex systems of humans and nature rarely change in gradual, expected ways. Instead, changes often occur suddenly, with major, non-linear losses of human and ecological capital. Once these unexpected changes occur, it can be difficult to restore … Continue reading Early warning indicators in aquatic ecosystems

Bird communities in a land of droughts and flooding rains: riparian tree cover as climate refugia

In this post Dale Nimmo, Angie Haslem and Andrew Bennett discuss their recent paper ‘Riparian tree cover enhances the resistance and stability of woodland bird communities during an extreme climatic event’ You can also watch a slide cast about this research and related papers, in the form of an Australian bush poem. Something alarming happened in the woodlands of southern Australia last decade. The birds … Continue reading Bird communities in a land of droughts and flooding rains: riparian tree cover as climate refugia

The role of subordinate plant species in supporting soil food web stability

In this post Associate Editor Paul Kardol discusses a paper he recently handled by Yuanhu Shao and colleagues ‘Subordinate plants sustain the complexity and stability of soil micro-food webs in natural bamboo forest ecosystems’ Is it the dominant plant species that rule the system? Some theories suggest so. But, the idea that only the dominants are important is too simplistic and there is increasing evidence … Continue reading The role of subordinate plant species in supporting soil food web stability

How network analyses can help to find out what happens to ostrich farming after an avian influenza outbreak

In this post Craig Allen and Hannah Birge discuss a paper from Christine Moore, John Grewar and Graeme S. Cumming ‘Quantifying network resilience: comparison before and after a major perturbation shows strengths and limitations of network metrics’ Humans are very good at creating mental models to simplify nature’s complexity, to make its many parts and interactions more understandable. Approaches that exemplify this include hierarchy theory, panarchy … Continue reading How network analyses can help to find out what happens to ostrich farming after an avian influenza outbreak

Ecological considerations for an urban marine environment

In this post Filippo Ferrario discusses his recent paper ‘The overlooked role of biotic factors in controlling the ecological performance of artificial marine habitats’ Summer is going to be over soon and many of us have spent the vacation enjoying sea beaches, practising aquatic sports or looking for a pristine marine landscape, where to hike or a wonderful sunset to cherish. Did you realize how … Continue reading Ecological considerations for an urban marine environment

Defining a successful river restoration project

In this post Associate Editor Tadeu Siqueira discusses a paper he recently handled by Daniel Hering and colleagues ‘Contrasting the roles of section length and instream habitat enhancement for river restoration success: a field study of 20 European restoration projects’ Streams and rivers are among the most degraded ecosystems in the world. In comparison to oceans, these ecosystems contain a tiny portion of the total … Continue reading Defining a successful river restoration project

Making the most of pollinators to improve and predict crop yields

In this post Lucas Garibaldi discusses his recent Review article ‘Trait matching of flower visitors and crops predicts fruit set better than trait diversity‘ Sustainable management of agroecosystems is a global challenge, with more than 35 % of the Earth’s land area covered by farmland. It has been suggested that species diversity is critical for sustainability because it increases the level and stability of agroecosystem … Continue reading Making the most of pollinators to improve and predict crop yields

Ancient woodland restoration

In this post Beth Atkinson discusses her recent paper ‘A comparison of clearfelling and gradual thinning of plantations for the restoration of insect herbivores and woodland plants’ Forests are valued across the globe for their history and heritage, as well as their importance for biodiversity. They display their historical use, for example through coppice stools, and are evocative like perhaps no other habitat, conjuring images … Continue reading Ancient woodland restoration

A more natural method of biocontrol

In this post Associate Editor Yann Clough discusses a paper he recently handled by Mattias Jonsson and colleagues ‘Experimental evidence that the effectiveness of conservation biological control depends on landscape complexity’ Brassica crops worldwide are attacked by a range of herbivorous insects, and frequent insecticide use is common. New research shows that the natural biological control of pests can be achieved by establishing strips of … Continue reading A more natural method of biocontrol

Satellite-tagging the black kite

In this post Fabrizio Sergio discusses his recent paper ‘No effect of satellite tagging on survival, recruitment, longevity, productivity and social dominance of a raptor, and the provisioning and condition of its offspring’ Ecologists are using ever smaller and more sophisticated electronic devices to track the movements of animal species, even small songbirds and butterflies, all around the globe. These studies are producing leapfrog advances … Continue reading Satellite-tagging the black kite
