The spread of non‐native species

Biological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Struktur Komunitas Perifiton Dibagian Hulu Sungai Cisadane, Kawasan Taman Nasional Gunung Halimun Salak, Jawa Barat [PDF]

, 2017
Perifiton is one community of organisms that can adapt and thrive in the river, and relatively settled in one location. Riparian vegetation in the Mountain Halimun-Salak National Park could be expected to affect the community structure of periphyton. The

Stand-level drivers of tree-species diversification in Mediterranean pine forests after abandonment of traditional practices [PDF]

, 2015
The progressive abandonment of traditional forest management over the last few decades has led to significant densification processes in most Mediterranean pine stands.

The As and Bs of titi monkey linguistics: why emotional communication is not the enemy

Biological Reviews, EarlyView.
ABSTRACT The alarm call sequences of titi monkeys (genera Plecturocebus, Callicebus and Cheracebus) have sparked important debates over whether they exhibit parallels with human language. Some researchers consider these sequences to involve both semantics and syntax, while others argue that the sequences convey semantic information without syntax.

Comparison of Assimilation Rates in Leaves at Various Nodes in Canopies of Three Spring Wheat Cultivars with Different Plant Forms

Plant Production Science, 1998
This study was conducted to reveal the ideotype of wheat (Triticum aestivum L.) canopy structure for high yield and biornass productivity. The assimilation rate and nitrogen contents of the flag, second, third and lower leaves and the ear of the main ...

Spatial metrics in fire ecology: seeking consistency amidst complexity

Biological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Canopy Structural Changes in Black Pine Trees Affected by Pine Processionary Moth Using Drone-Derived Data

Drones
Pine species are a key social and economic component in Mediterranean ecosystems, where insect defoliations can have far-reaching consequences. This study aims to quantify the impact of pine processionary moth (PPM) on canopy structures, examining its ...

Tropical forest canopies and their relationships with climate and disturbance: results from a global dataset of consistent field-based measurements

Forest Ecosystems, 2018
Background Canopy structure, defined by leaf area index (LAI), fractional vegetation cover (FCover) and fraction of absorbed photosynthetically active radiation (fAPAR), regulates a wide range of forest functions and ecosystem services.

Low Diversity of Intertidal Canopy-Forming Macroalgae at Urbanized Areas along the North Portuguese Coast

Diversity, 2020
Canopy-forming macroalgae are the main component in some of the most diverse and productive coastal habitats around the world. However, canopy-forming macroalgae are very sensitive to anthropogenic disturbances.
