Distribution of flying insects across landscapes with intensive agriculture in temperate areas
Ecological Indicators, 2021 The abundance of insects has been strongly decreasing over the last decades, at least in the temperate zones of North America and Europe. This decrease has generally been attributed to increased human activity, especially increased agricultural ...

Local competition and metapopulation processes drive long-term seagrass-epiphyte population dynamics [PDF]
, 2013 It is well known that ecological processes such as population regulation and natural enemy interactions potentially occur over a range of spatial scales, and there is a substantial body of literature developing theoretical understanding of the interplay ...

A positive relationship between the abundance of ammonia oxidizing archaea and natural abundance δ15N of ecosystems [PDF]
, 2013 We present a significant relationship between the natural abundance isotopic composition of ecosystem pools and the abundance of a microbial gene. Natural abundance 15N of soils and soil DNA were analysed and compared with archaeal ammonia oxidizer ...

The relationship between natural resource abundance and happiness for lower middle-income countries [PDF]
BIO Web of ConferencesThe resource curse, a concept linking natural resource wealth to poor economic performance, is well-documented. Separately, emerging studies suggest economic growth correlates with increased happiness. However, the intersection of these two areas—natural

Can Rock-Rubble Groynes Support Similar Intertidal Ecological Communities to Natural Rocky Shores?
Land, 2020 Despite the global implementation of rock-rubble groyne structures, there is limited research investigating their ecology, much less than for other artificial coastal structures. Here we compare the intertidal ecology of urban (or semi-urban) rock-rubble

Meta-analysis reveals that seed-applied neonicotinoids and pyrethroids have similar negative effects on abundance of arthropod natural enemies [PDF]
PeerJ, 2016 Background Seed-applied neonicotinoids are widely used in agriculture, yet their effects on non-target species remain incompletely understood. One important group of non-target species is arthropod natural enemies (predators and parasitoids), which ...

The new face of isotopic NMR at natural abundance [PDF]
Magnetic Resonance in Chemistry, 2016 The most widely used method for isotope analysis at natural abundance is isotope ratio monitoring by Mass Spectrometry (irm‐MS) which provides bulk isotopic composition in 2H, 13C, 15N, 18O or 34S. However, in the 1980s, the direct access to Site‐specific Natural Isotope Fractionation by Nuclear Magnetic Resonance (SNIF‐NMRTM) was immediately ...

Conformational studies of various hemoglobins by natural-abundance 13C NMR spectroscopy [PDF]
, 1972 Studies of variously liganded hemoglobins (both from human and rabbit) by natural-abundance 13C NMR spectroscopy have revealed apparent conformational differences that have been interpreted on the basis of two quaternary structures for the α2ß2 tetramer,

Biological nitrogen fixation of Biserrula pelecinus L. under water deficit
Plant, Soil and Environment, 2012 The present work studied the effects of water deficiency conditions on the biological nitrogen fixation of three native rhizobia (SafPt12, SafPt6, and AjuPt16) isolated from Biserrula pelecinus L., and a reference strain Mesorhizobium ciceri biovar ...
