If some individual plants of a species consistently attracted one type of pollinator, while other individual plants of that same species consistently attracted a different type of pollinator, what could be the possible consequence?

In which nations is grazing land being used sustainably? In which nations is forest land being used sustainably?

Bean beetles, Callosobruchus maculatus, get their lifetime nutrition from the bean seeds (family Fabaceae) on which their mother lays her eggs. The specific bean on which each egg is laid determines the future success of the larva that develops from that egg. Choosing where to lay an egg is the most important decision a female bean beetle will make for her offspring, yet even within one bean species the seeds available may be very different in quality. Seeds vary in size (even if from the same plant), so the amount of resource available to larvae on different beans will not be the same. Seed mass may vary by as much as 50% among mung beans purchased in a local store, a species on which Callosobruchus develops normally and may complete its lifecycle.   During adulthood the primary activity of the beetle is____________________________.     seeking shelter     feeding their young     eating     mating     drinking

The large and heavy seeds of the limber pine (Pinus flexilis) lack the wings on seeds characteristic of most pines. The seeds are the primary food source for Clark’s nutcracker which harvests seeds after the cones open. It then caches thousands of seeds each summer and fall in locations far from the original tree to eat later in the year. During years when many cones and seeds are produced, the nutcracker caches 3-5x the number of seeds actually eaten. When they are present, tree squirrels remove the cone before it opens before the seeds are fully developed, and will eat the seeds immediately or cache the cone for later consumption.  Question:  Scientists were interested to see whether the two seed harvesters would affect seed and cone traits. They compared cone and seed traits in areas that had nutcrackers but tree squirrels were either present or absent. Where squirrels were present, cone mass was larger but there were fewer seeds per cone, and smaller kernels per seed. What do the…
