Vulture Exclusion Halves Large Carcass Decomposition Rates and Doubles Fly Abundance. [PDF]

Ecol Evol
We experimentally excluded vultures from pig carcasses (Sus scrofa) in Costa Rica, under different habitats and across seasons with the aim to assess the impact of vulture population decline on carrion decomposition and insect abundance. Vulture exclusion halved carcass decomposition rates and doubled fly abundance, while dung beetle abundance remained

Detecting mass mortality events in wildlife populations. [PDF]

Conserv Biol
Abstract Reports in the literature of mass mortality events (MMEs) involving diverse animal taxa are increasing. Yet, many likely go unobserved due to imperfect detection and infrequent sampling. MMEs involving small, cryptic species, for instance, can be difficult to detect even during the event, and degradation and scavenging of carcasses can make ...

EFECTO DE BORDE SOBRE EL PROCESO DE DESCOMPOSICIÓN DE HOJARASCA EN BOSQUE NUBLADO [PDF]

Acta Biológica Colombiana, 2011
Los fragmentos de bosque son delimitados por bordes y rodeados de matriz circundante. La interacción entre estas comunidades disimiles en estructura y composición, se define como efecto de borde.

Combining surface and soil environmental DNA with artificial cover objects to improve terrestrial reptile survey detection. [PDF]

Conserv Biol, 2022
Abstract Reptiles are increasingly of conservation concern due to their susceptibility to habitat loss, emerging disease, and harvest in the wildlife trade. However, reptile populations are often difficult to monitor given the frequency of crypsis in their life history.

Soil carbon storage is related to tree functional composition in naturally regenerating tropical forests. [PDF]

Funct Ecol, 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Regenerating tropical forests are increasingly important for their role in the global carbon cycle. Carbon stocks in above‐ground biomass can recover to old‐growth forest levels within 60–100 years.

Ectomycorrhizal fungi and the nitrogen economy of Nothofagus in southern Patagonia. [PDF]

Ecol Evol
Ectomycorrhizal fungi play essential roles in nitrogen cycling and plant nutrient uptake at high latitudes. However, they have disproportionately been studied in boreal forests dominated by evergreen conifers. We characterized ectomycorrhizal associations and the nitrogen economy of co‐occurring deciduous and evergreen angiosperms from the genus ...

No home‐field advantage in litter decomposition from the desert to temperate forest

Functional Ecology, Volume 37, Issue 5, Page 1315-1327, May 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Litter decomposition rates are determined by the interplay of climate, decomposer organisms and litter quality. It has been suggested that the decomposer community may be locally adapted to litter quality, providing a home‐field advantage (HFA) resulting in accelerated ...

Trait functional diversity explains mixture effects on litter decomposition at the arid end of a climate gradient

Journal of Ecology, Volume 110, Issue 9, Page 2219-2231, September 2022., 2022
Litter mixing did not have strong effects on decomposition rates across the studied climatic gradient overall, and the direction and intensity of the mixture effects were context dependent. The effects were stronger and more negative in the dryer ecosystems.

Structural and compositional dimensions of phytochemical diversity in the genus Piper reflect distinct ecological modes of action

Journal of Ecology, Volume 110, Issue 1, Page 57-67, January 2022., 2022
Crude extract 1H NMR diversity synthesizes the compositional diversity and structural complexity of phytochemical mixtures. Plants can develop chemical diversity through different combinations of structural and compositional biosynthetic mechanisms; thus, methods incorporating both dimensions of phytochemical diversity can provide new theoretical ...

Descomposición Primaria [PDF]

, 2022
Por el Teorema fundamental de la Aritmética todo número entero n > 1 se puede descomponer de modo ́unico como producto de un número finito de números primos, es decir, como producto de un número finito de números primarios (potencia de primos).
