THE ECOLOGY OF MUTUALISM [PDF]

open access: yes, 1982
Elementary ecology texts tell us that organisms interact in three fundamen­ tal ways, generally given the names competition, predation, and mutualism. The third member has gotten short shrift (264), and even its name is not generally agreed on.

Estimation of photosynthetic capacity using MODIS polarization: 1988 proposal to NASA Headquarters [PDF]

open access: yes
The remote sensing community has clearly identified the utility of NDVI (normalized difference vegetation index) and SR (simple ratio) and other vegetation indices for estimating such metrics of landscape ecology as green foliar biomass, photosynthetic ...

Disentangling the relationship between environmental drivers and productivity in subalpine wet grasslands

open access: yesFrontiers in Plant Science
IntroductionGrasslands exhibit significant variability in productivity across fine spatial scales, which is crucial for understanding terrestrial carbon cycling, particularly under global climate change.

Microparticles from dental calculus disclose paleoenvironmental and palaeoecological records

open access: yesEcology and Evolution
Plants have always represented a key element in landscape delineation. Indeed, plant diversity, whose distribution is influenced by geographic/climatic variability, has affected both environmental and human ecology.

Ecological aspects of plants introduction on the position of system analysis

open access: yesІнтродукція Рослин, 2010
Some debatable questions of plant ecology are analyzed. The necessity of selection of independent sections of ecology is discussed. The specific methods of ecology and possibility of their use on different stages of plant introduction process are ...

Implications of Liebig’s law of the minimum for tree-ring reconstructions of climate

open access: yesEnvironmental Research Letters, 2017
A basic principle of ecology, known as Liebig’s Law of the Minimum, is that plant growth reflects the strongest limiting environmental factor. This principle implies that a limiting environmental factor can be inferred from historical growth and, in ...
