Biodiversity loss disrupts seasonal carbon dynamics in a species-rich temperate grassland. [PDF]

Ecology
Abstract Biodiversity loss poses a significant threat to ecosystem functioning. However, much of the empirical evidence for these effects is based on artificial experiments that often fail to simulate the structure of natural communities. Hence, it is still unclear whether natural diversity losses would significantly affect the functioning of “real ...

The Influence of Plant Species Composition on an Endangered Grassland Specialist Reptile, the Hungarian Meadow Viper. [PDF]

Ecol Evol
The study investigated how the horizontal structure and functional composition of grassland vegetation influence the occupancy and density of the highly endangered Hungarian meadow viper. Using plant community data and viper surveys from 59 quadrats, the best models showed that vipers prefer wetter meadows with fewer and shorter plant species, and a ...

Mowing Modulates the Biotic Filter of Expansive Species. [PDF]

Ecol Evol
Management type and expansive species influence plant community diversity in complex ways. Overall increase of expansive species cover acts as biotic filter in reducing the alpha and beta taxonomic and phylogenetical diversity. However, the filtering effect is modulated by management type, being more intense under mown grasslands.

Sampling Big Sagebrush for Phytomass [PDF]

Journal of Range Management, 1977
Highlight: A double sampling procedure was employed for obtaining more reliable weight estimates for leaves, flowering stalks, live wood, dead wood, various combinations of the preceding, and total phytomass of sagebrush shrubs. Easily obtained dimension measurements were related to harvest categories using regression analyses. Volume (length x width x

Unveiling the Dietary Selection of Lowland Tapirs (<i>Tapirus terrestris</i>) in a Tropical Rainforest. [PDF]

Ecol Evol
Large terrestrial herbivores, such as lowland tapirs (Tapirus terrestris) present many dietary ecological roles in their habitat. In this article, we investigated the diet of lowland tapirs in a tropical rainforest combining different techniques such as DNA metabarcoding, fieldwork, and plant functional traits.

Phytomasse et productivité

BOIS & FORETS DES TROPIQUES, 1989
L'opération expérimentale mise en place dans la forêt guyanaise, appelée ECEREX, a permis d'y évaluer la phytomasse et de créer des liens entre celle-là et les données sylvicoles (hauteur de poitrine et surface terrière), valables pour la station considérée.La répartition de la phytomasse au sein des grands groupes végétaux montre la prédominance des ...

Dynamic bioproductivity of Scots pine stands within Northern Steppe of Ukraine conditions

Agrology, 2021
Dynamic changes in forest ecosystems, which can be both short-term and long-term, are assessed on the scale of long-term biologically determined stages, through the determination of age parameters.
