The abundance distribution of bee species is also typically highly skewed, making it difficult to accurately assess diversity when rarer species are unlikely to be caught. The effective number of species, or Hill numbers, provides a way forward by basing the response metric on the ...
Colony growth of the bumblebee, Bombus terrestris, in improved and conventional agricultural and suburban habitats Many bumblebee species are declining at a rapid rate in the United Kingdom and elsewhere. This is commonly attributed to the decline in floral resources th... D Goulson,W Hughes,L...
A.A small number of bee species are essential for crops such as apples and strawberries.B.The bees busied themselves at making honey.C.So,it really seems time to give bees a second chance.D.In fact,they are the world's most important pollinators....
The approach is illustrated by application to the problem of finding the number of species in a data set of Australasian tetragonula bees. Requirements here include two new statistics formalising the largest within-cluster gap and cluster separation. Due to the typical nature of expert knowledge, ...
speciesTribolium castaneumHerbst, 179724. CNV can be reliably detected using droplet digital PCR (ddPCR). However, the hardware is prohibitively expensive for widespread use25. The main objective of our work was therefore to develop method of sex detection in CPB larvae based on CNV using ...

D.To reduce the difficulty of the experiment. 4. What does the study find? A.Most animals create their own cultures. B.Strings are particularly attractive to bees. C.Animals may have good social learning ability. D.Bumblebees may be smarter than other bee species. ...
英语阅读解析高手进The Book Of Life So far,scientists have named about 1.8 million living species(物种),and that‘s just a small number of what probably exists on Earth.With so many plants,animal,and other living things covering the planet
The steady increase in sequenced genomes in re- cent years has provided a wealth of information available to address these questions. Here, we report the identification and prediction through extensive data mining of one or more additional SMC genes from 34 species. Our phylogenetic analysis of ...
£120bn ($150bn) and contribute around £690m ($850m) to the UK economy every year.So, bees are worth protecting, and although a small number of bee species are vital for crops such as oilseed rape, apples and strawberries, experts say we should be taking care of all our bees. ...
