This is actually not a gall as other answers have suggested. This is likely a fungus called Cedar-apple rust (Gymnosporangium juniperi-virginianae). The fungus only thrives in the presence of both Juniperus virginiana (Eastern red cedar) and apple (Malus spp.) trees. The leaf in the picture belongs to some species of the apple genus and the growths are ...

Albizia julibrissin (Persian silk tree) is doubly compound (AKA bipinnate) and has a conspicuous pink/white fluffy flower. This tree is an Asian native, but it's a commonly cultivated (and equally commonly escaped) plant in the U. S. Should be able to find it in numerous locations. Look in yards and along roads. ...

Forest Succession 101 Pines are actually fast-growing, shade-intolerant, early-successional species. When land is allowed to lay fallow after being cleared by fire, wind storms, human land use or other major disturbance, the successional sequence will begin. At first only herbs and grasses grow, but eventually these are shaded out by shrubs and tree ...

Phylogeny and evolution of ferns (monilophytes) with a focus on the early leptosporangiate divergences: The monilophytes (= Infradivision Moniliformopses, sensu Kenrick and Crane, 1997⇓) share a distinctive vasculature, having protoxylem confined to lobes of the xylem strand (Stein, 1993⇓), therefore the Latin moniliformis appellation for ...

There are at least three possible explanations (and quite likely more): 1) You may be correct in suggesting that the OTT isn't "very coherent."* In other words, they may have a little work to do. I don't know enough about the site to offer a solid opinion. 2) The OTT may be unintentionally repeating someone else's error(s). 3) The OTT has to work with the ...

Trees fruit before the monsoon season to maximize seed germination and seedling recruitment. previous studies have shown that in many species, fruiting occurs just before the wet season such that seeds germinate and establish during the wet season when conditions are most favourable. Smythe N. 1970 Relationships between fruiting seasons and seed dispersal ...

To my knowledge, Populus is one of the main model species when it comes to perennials and trees. It is for instance used in several sequencing projects, and to study accelerated breeding in strains that are promoted to flower at a very early age. Excluding trees, other perennial species that has been described as model species are Panicum virgatum ...

From what I know of ant-Acacia mutualisms, I've never heard of an ant gall in an Acacia. The link in your question also never mentions a gall. You've likely confused either domatia or Beltian bodies as a gall. Both differ greatly from galls in that domatia or Beltian bodies are created by the plant and not by the insect. Domatia are small plant-made ...
