Unravelling Darwin's entangled bank: architecture and robustness of mutualistic networks with multiple interaction types

Unravelling Darwin's entangled bank: architecture and robustness of mutualistic networks with multiple interaction types.

Trying to unravel Darwin's entangled bank further, we describe the architecture of a network involving multiple forms of mutualism (pollination by animals, seed dispersal by birds and plant protection by ants) and evaluate whether this multi-network shows evidence of a structure that promotes robustness. We found that species differed strongly in their contributions to the organization of the m...

Coevolution and the architecture of mutualistic networks.

Although coevolution is widely recognized as an important evolutionary process for pairs of reciprocally specialized species, its importance within species-rich communities of generalized species has been questioned. Here we develop and analyze mathematical models of mutualistic communities, such as those between plants and pollinators or plants and seed-dispersers to evaluate the importance of...

study of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives

برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...

The architecture of weighted mutualistic networks

Several ecosystem services directly depend on mutualistic interactions. In species rich communities, these interactions can be studied using network theory. Current knowledge of mutualistic networks is based mainly on binary links; however, little is known about the role played by the weights of the interactions between species. What new information can be extracted by analyzing weighted mutual...
