Challenges for freshwater invertebrate conservation
Freshwater invertebrate conservation faces 5 important challenges. First, ;10,000 species of freshwater invertebrates around the world may already be extinct or imperiled. Second, human pressures on freshwater resources are intense and will increase in the coming decades, putting yet more species at risk. Third, scientific knowledge about freshwater invertebrates, although substantial and usefu...
متن کاملConservation of progesterone hormone function in invertebrate reproduction.
Steroids play fundamental roles regulating mammalian reproduction and development. Although sex steroids and their receptors are well characterized in vertebrates and several arthropod invertebrates, little is known about the hormones and receptors regulating reproduction in other invertebrate species. Evolutionary insights into ancient endocrine pathways can be gained by elucidating the hormon...

system service. It is estimated that 60 to 80 percent of the world’s 250,000 flowering plants depend on animals—mostly insects—for pollination (Kremen et al. 2007). Eighty-seven of the world’s 124 most commonly cultivated crops are animal pollinated, and insectpollinated forage plants such as alfalfa and clover provide feed for livestock. Roughly thirtyfive percent of global crop production is ...
متن کاملBruce Nicklas: Pioneering studies on spindle forces
B y the 1960s, researchers had developed the microscopy techniques needed to observe and record live cells undergoing cell division. But the mechanisms used by the mitotic apparatus to faithfully distribute DNA into daughter cells remained mysterious. Bruce Nicklas is responsible for many of the groundbreaking studies that helped sweep the veil of mystery away from chromosome segregation. By pu...
متن کاملStudies on Invertebrate Hemoglobins (erythrocruorins)
1. Two high molecular invertebrate hemoglobins (the erythrocruorins of Lumbricus terrestris and of Nereis virens) as well as the low molecular erythrocruorin of Glycera dibranchiata Ehlers were studied. Their physical chemical properties were compared with those of vertebrate hemoglobin. 2. The hemin of the blood pigment of Glycera dibranchiata Ehlers was shown to be identical with that of vert...
