A hysteretic model predicts a time lag in the response of herbaceous layer variables (e.g., cover, diversity) to decreasing N deposition. To the contrary, virtually all such variables displayed a surprising sensitivity to decreased N. ABSTRACT Increases in nitrogen (N) emissions during the 20th century resulted in the atmospheric deposition of N ...

True and False Foodplants of \u3ci\u3eCallosamia Promethea\u3c/i\u3e (Lepidoptera: Saturniidae) in Southern Michigan [PDF]
A survey in 1980 of the associations of over 400 cocoons of Callosamia promethea Drury in vegetation along and adjacent to southern Michigan roadsides gave evidence for seven species of true larval foodplants (not including two others known in the area ...

Summary Roots are responsible for soil water uptake, yet little is known about how variation in fine‐root traits relates to whole‐tree water movement, particularly during periods of drought. By combining a 3‐yr dataset monitoring sap flow rates with measures of fine‐root biomass, length, and morphology across 10 tree species, we addressed hypotheses ...

Structure and sequence evolution in the pennycress (Thlaspi arvense) pangenome
Summary Eukaryotic genomes harbor many forms of variation, including nucleotide diversity and structural polymorphisms, which experience natural selection and contribute to genome evolution and biodiversity. Harnessing this variation for agriculture hinges on our ability to detect, quantify, catalog, and deploy genetic diversity. Here, we explore seven

Dendrológiai kertek a 19. századi magyarországi kertépítészetben = Dendrological gardens in 19th century garden architecture in Hungary [PDF]
Disszertációm elsődleges célja, hogy összegyűjtsem azokat a még létező és már nem létező magyar tájképi kerteket, amelyek növényalkalmazásában és kerti térkompozíciójának kialakításában a különböző egzóta fafajok jelentős szerepet játszottak.
