#杏鮑菇竟然會吃蟲❓❓❓❓❓
#顯微鏡下的大逃殺
#火爆開演中📣📣📣📣

🎥🎥主演：

線蟲 (門) ----地球上數量最多的動物，個性歡脫無腦，到處破壞闖禍，但容易受騙。

真菌----杏鮑菇、線蟲捕捉菌等等，個性沉靜腹黑，擅長設套、下毒，殺蟲不眨眼！

🎥🎥劇情簡介：

地球土壤中充滿線蟲，真菌處處都能遇上線蟲。當真菌感覺環境中的養分不足，開始飢餓了，即會獵殺身邊的線蟲補充營養。

中研院薛雁冰助研究員發現，不同真菌竟不約而同「獨立」演化出不同的吃蟲技巧，像是線蟲捕捉菌會設陷阱、杏鮑菇會下毒。

這個現象不但有趣，也有機會發展生物防治，因為寄生性線蟲也可能被相同機制殺死。人類只要從線蟲的天敵身上偷學幾樣殺蟲絕招，即有機會開發更有效的寄生蟲治療藥物......

Abstract
Community ecology is traditionally species-based and assumes that species comprise identical individuals. However, intraspecific variation is ubiquitous in nature because of ontogenetic growth and critical in food-we dynamics. To understand individual interaction-mediated food webs, researchers have recently focused on body size as the most fundamental biological aspect and assessed a parameter called the predator–prey mass ratio (PPMR). Herein, I review the conceptual development of the PPMR and suggest four major concerns regarding its measurement: (1) PPMR should be measured at the individual level because species-averaged values distort actual feeding relationships, (2) individual-level PPMR data on gape-unconstrained predators (e.g., terrestrial carnivores) are limited because previous studies have targeted gape-limited fish predators, (3) predators’ prey size selectivity (preferred PPRM) is conceptually different from dietary prey size (realized PPMR) and should be distinguished by incorporating environmental prey abundance information, and (4) determinants of preferred PPMR, rather than those of realized PPMR, should be identified to describe size-dependent predation. Future studies are encouraged to explore not only predation but also other interaction types (e.g., competition, mutualism, and herbivory) at the individual level. However, this is not likely to occur while ecological communities are still considered to be interspecific interaction networks. To resolve this situation and more comprehensively understand biodiversity and ecosystem functioning, I suggest that community ecology requires a paradigm shift in the unit of interaction from species to individuals, similar to evolutionary biology, which revolutionized the unit of selection, because interactions occur between individuals.
