Background Insect pollinators play an important role in crop pollination, but the relative contribution of wild pollinators and honey bees to pollination is currently under debate. There is virtually no information available on the strength of pollination services and the identity of pollination service providers from Asian smallholder farming syst...
Article
Pollination by insects is key for the productivity of many fruit and non-graminous seed crops, but little is known about the response of pollinators to landscapes dominated by small-holder agriculture. Here we assess the relationships between landscape context, pollinator communities (density and diversity) and pollination of oilseed rape in 18 lan...

Full-text available
While the biocontrol potential of natural enemies is well established, it is largely unknown how landscape‐mediated effects on pest and natural enemy communities impact the cascade of biocontrol potential, crop injury, yield and profit, taking into account crop management and surrounding landscape composition. We compared natural biocontrol with ch...
Article
Measures of β‐diversity characterizing the difference in species composition between samples are commonly used in ecological studies. Nonetheless, commonly used dissimilarity measures require high sample completeness, or at least similar sample sizes between samples. In contrast, the Chord‐Normalized Expected Species Shared (CNESS) dissimilarity me...

Full-text available
Organic farming supports higher biodiversity than conventional farming, but at the cost of lower yields. We conducted a meta‐analysis quantifying the trade‐off between biodiversity and yield, comparing conventional and organic farming. We developed a compatibility index to assess whether biodiversity gains from organic farming exceed yield losses,...
Article
There is a global concern of pollinator declines and linked ecosystem service losses. However, although land-use changes are a primary threat to biodiversity, how land-use change affects pollinator communities, pollination networks and fruit-set of food crops is poorly understood. The impact of land-use changes is especially understudied in tropica...

Reforested areas can act as important carbon (C) sinks. In China, extensive reforestation has been carried out in mountainous regions, with resulting C storage affected by forest age, forest type and environmental settings. Evaluations of forest C sequestration therefore require a detailed spatio-temporal analysis of C storage dynamics. Here, we us...

Analysis of the complex relationships between plants and insects is important for biological research in our country. Although Chinese scholars tended to publish relevant literature in foreign journals, domestic journals were still the main targets for scientific research publications in this field. Studies on plant-insect relationships in domestic...
Article
Agricultural diversification is proposed as a solution to achieve food security and sustainability in intensified agriculture, but a large-scale policy implementation is lacking. As a leading agricultural producer, the integration of diversification in major policies in China could provide an important example of how to facilitate a sustainable foo...
Article
Sampling flower-visiting insects in agricultural fields at large spatial and temporal scales is significant for understanding local insect pollinator communities. The most commonly used method, pan trap, has been criticized due to its attractant bias. A window trap (also referred to as the flight-intercept trap) is a non-attractant sampling method,...
Article

Synthetic pesticides are core features of input-intensive agriculture and act as major pollutants driving environmental change. Agroecological science has unveiled the benefits of biodiversity for pest control, but research implementation at the farm-level is still difficult. Here we address this implementation gap by using a biblio-metric approach...
Article
1. Traditional smallholding-dominated agricultural landscapes in Southern China are increasingly homogenized and consolidated, resulting in large mono-cropped fields and impoverished pollinator communities. The exact impact of this farmland consolidation on composition and functional traits of wild bee communities remains poorly understood. 2. We s...

1. Environmental regime (or environmental legacy or historical legacy) is the environmental dynamic characteristics over a given (either long or short) time period, such as frequency of mean or extreme events and rate of change, which might be masked by using only contemporary variables. 2. We present SER, an R package for estimating environmental...
Article
Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we are limited in our capacity to understand the variation in pollination benefits to crop y...
