Aquatic and Littoral Successions in Various Post‐Mining Sites—Patterns and Possible Use in Ecological Restoration

Land Degradation &Development, EarlyView.
ABSTRACT Vegetation succession in aquatic and littoral habitats has received much less attention than terrestrial habitats have. We sampled differently aged successional stages at five different types of post‐mining sites, that is, sandpits, stone quarries, clay quarries, brown coal spoil heaps and black coal subsidences, across the Czech Republic ...

The phenological phases of flowering and pollen seasons of spring flowering tree taxa against a background of meteorological conditions in Kraków, Poland

Acta Agrobotanica, 2016
The aim of the study was to compare phenological observations of pollen seasons of selected early spring trees. Special attention was paid to meteorological conditions which favored or did not favor tree flowering and pollen release.

Temporal variation of the total nitrogen concentration in aereal organs of nitrogen fixing and non fixing riparian species [PDF]

, 1992
Changes in nitrogen concentration was determinated in samples of Alnus glutinosa, Elaeagnus angustifolia, Populus x canadiensis and Ailanthus altissima leaves, petioles and branches periodically during a year.

Species identity and spatial scale drive context‑dependent tree diversity effects in a Finnish forest experiment

Oikos, EarlyView.
Tree species diversity is known to affect tree growth and leaf traits, which in turn can influence various ecosystem processes. However, the reported direction of these tree diversity effects is inconsistent, indicating that their outcomes depend strongly on ecological context.

Evaluation of seed morphology characteristics of Alnus taxa in Iran

Turczaninowia, 2021
Alnus Mill. is a problematic genus of Betulaceae, and there are several intrageneric classifications for the genus. Alnus species are widely distributed in the Hyrcanian forest of Iran, and different species with some intraspecific taxonomic ranks ...

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

People and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Detecting social‐ecological fit in Natura 2000 governance and management: Evidence from LIFE projects focused on forest protected habitat types

People and Nature, EarlyView.
Abstract Protected areas represent complex social‐ecological systems that require governance and management approaches that valorise and enhance positive relationships between people and nature. This study analyses the alignment between social and ecological systems to detect the social‐ecological fit of projects focused on biodiversity conservation ...

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects

Wildlife Biology, EarlyView.
Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)
