plant_pol_vazquez: Vazquez & Simberloff plant-pollinator webs
Eight bipartite networks of plants and pollinators, from the Nahuel Huapi National Park and surrounding areas in Rio Negro, Argentina, from September 1999 to Feburary 2000. Edge weights represent the frequency of species interaction, and there is a common set of vertices across all eight webs.
This network has 144 nodes and 36 edges.

Weighted Food Webs Make Computing Phylogenetic Diversity So Much Harder
Phylogenetic trees represent certain species and their likely ancestors. In such a tree, present-day species are leaves and an edge from u to v indicates that u is an ancestor of v. Weights on these edges indicate the phylogenetic distance. The phylogenetic diversity (PD) of a set of species A is the total weight of edges that are on any path between the root of the phylogenetic tree and a species in A. Selecting a small set of species that maximizes phylogenetic diversity for a given phylogene…

Weekend #Plankton Factoid 🦠🦐
The poles are cold and dark half the year, so you might think these areas were low productivity. Nope. These are some of the highest productivity and efficient food webs on the planet, which is why whales will travel half the globe to feed here. When sunlight returns in spring, long days and nutrients drive intense blooms. There was a question of nutrient sources…

image/jpeg an illustration of the Arctic productivity cycle showing the sun rising higher in April to provide sunlight to support the growth of algae and phytoplankton. The summer sun drives production of dense bloos in June, leading to growth of grazing zooplankton which drives vertical flux of nutrients via fecal matter to the deep waters. Production gradually declines during as the phytoplankton use up nutrients and reduced sunlight. Illustration: Alexander Keck & Paul Wassmann (1993), modif…
