[求助] freshwater biology

最近我在看淡水生态学报中的这篇文章：Life history traits and abundance can predict local colonisation and extinction rates of freshwater mussels，其中在这段当中Mantle
lures, found in the Lampsilini, are pigmented modifications of the mantle that mimic prey items (i.e. minnows,crayfish) of predacious fish. These flaps surround the swollen gills (marsupia) where the female broods the glochidia. Gravid females extend their posterior shell margins above the substratum and periodically move the mantle flaps to resemble swimming prey fish. When a host fish attacks the mantle flaps, the gills are ruptured and glochidia are released and carried onto the gills by respiratory currents (Barnhart et al., 2008). Mantle magazines, found in the Quadrulini, function similarly to lures. For this analysis, I defined no active host attraction (NA) to include mussel species that broadcast free larvae [e.g. Megalonaias nervosa (Rafinesque)], those that release larvae into a mucus web [e.g. Pyganodon grandis (Say)] and those that deposit loose conglutinates without specialised adaptations to attract host fish [e.g. Amblema plicata (Say)]. I defined active host attraction (A) as species that attract hosts via conglutinates, mantle lures or mantle magazines 由于几个单词不知道该怎么翻译，以至于半天搞不懂其意思，希望能有个懂生态学的大神能帮我理解下这段话。
