Variation in performance of beech saplings of 7 European provenances under shade and full light conditions

, 2001
The use of beech seedlings from South-East European and North-West (NW) provenances for underplanting in coniferous forests in North-West Europe was investigated by means of experimental shading.

Unbiased inference of plant flowering phenology from biological recording data

, 2015
Phenology is a key indicator and mediator of the ecological impacts of climate change. However, studies monitoring the phenology of individual species are moderate in number, taxonomically and geographically restricted, and mainly focused on spring ...

Lagging spawning and increasing phenological extremes jeopardize walleye (Sander vitreus) in north‐temperate lakes

Limnology and Oceanography Letters
The phenology of critical biological events in aquatic ecosystems is rapidly shifting due to climate change. Growing variability in phenological cues can increase the likelihood of trophic mismatches (i.e., mismatches in the timing of peak prey and ...

Reestablishment and a new name for Actinostemon grandifolius (Müll.Arg.) Pax

Nordic Journal of Botany, EarlyView.
The genus Actinostemon has undergone several changes in its circumscription due to persistent difficulties in its taxonomic placement. The taxonomic history of the genus is controversial and marked by nomenclatural issues, particularly involving its type species, Actinostemon grandifolius Klotzsch, including incorrect synonymizations and the ...

The Statistical Analysis of Insect Phenology

Weintroduce two simple methods for the statistical comparison of the temporal pattern of life-cycle events between two populations. The methods are based on a translation of stagefrequency data into individual Ôtimes in stageÕ.

Novelty for the flora of Espírito Santo, Brazil: a new species of Ouratea Aubl. (Ochnaceae)

Nordic Journal of Botany, EarlyView.
Here, we describe and illustrate the new species Ouratea oberdanii Fraga & Deccache, which is named after Dr Oberdan José Pereira. This new species is found in the mountainous regions of the evergreen Atlantic Forest in the Brazilian state of Espírito Santo. Ouratea oberdanii is similar to O. linearis (A.Gray) Sastre & Offroy and O.

Cybianthus anthuriophyllus (Primulaceae), a new record for the flora of Colombia: distribution modeling and conservation assessment

Nordic Journal of Botany, EarlyView.
Cybianthus anthuriophyllus (Primulaceae) was previously known from eastern Ecuador and northern Peru. Here we document the first confirmed occurrences of this species in Colombia and develop a distribution model based on collections from the Andean–Amazonian foothills of Caquetá, Cauca, and Putumayo departments, in order to clarify its conservation ...

Landscape diversity facilitates population growth and abundance of polyphagous Lygus pratensis in cotton fields of northern Xinjiang

New Plant Protection, EarlyView.
Increased landscape diversity showed significantly positive effects on the population growth rate and abundance of polyphagous Lygus pratensis in cotton fields, which may be attributed to the enhanced continuity and heterogeneity of host plant resources in more diverse agricultural landscapes.

Inferring breeding phenology and reproductive success from the emergence of juveniles in population monitoring

Oikos, EarlyView.
Phenological shifts caused by climate change are increasingly documented in wild populations. These events may be inferred by examining changes in population abundance and age structure throughout the breeding season, often using citizen science. However, several gaps still limit optimal use of such data.
