Matrix population models from 20 studies of perennial plant populations

, 2012
Demographic transition matrices are among the most commonly applied population models for both basic and applied ecological research. The relatively simple framework of these models and simple, easily interpretable summary statistics they produce have ...

Signs in isotope shifts: a perennial headache [PDF]

arXiv, 2022
Signs of the different contributions to the isotope shift of an atomic line are discussed in details to clarify some confusing differences between the electronic parameters calculated with RIS (Naz\'e et al. Comput. Phys. Commun. 184 (2013) 2187 ; Ekman et al. Comput. Phys. Commun. 235 (2019) 433) and those appearing in other commonly used expressions.

A new concept for the control of Elytrigia repens in organic crop production [PDF]

, 2012
The control of perennial weeds in organic crop production needs reconsideration to minimise losses of nutrients through leaching. Long post-harvest periods with mechanical weed control hinder a plant cover with the purpose of taking up nutrients not ...

Management of fruit species in urban home gardens of Argentina Atlantic Forest as an influence for landscape domestication [PDF]

, 2017
Home gardens are considered germplasm repositories and places for experimentation, thus they are key sites for the domestication of plants. Domestication is considered a constant process that occurs along a continuum from wild to managed to domesticated ...

Using large language models to extract plant functional traits from unstructured text

Applications in Plant Sciences, EarlyView.
Abstract Premise Functional plant ecology seeks to understand how functional traits govern species distributions, community assembly, and ecosystem functions. While global trait datasets have advanced the field, substantial gaps remain, and extracting trait information from text in books, research articles, and online sources via machine learning ...

Building a botanical foundation for perennial agriculture: Global inventory of wild, perennial herbaceous Fabaceae species

Plants, People, Planet, 2019
Societal Impact Statement Agroecosystems are constantly evolving to meet the needs of a growing population in a sustainable manner. Concerns about ecological impacts of agriculture, including soil loss, have focused attention on crops that provide both ...

Scientific results of the Bryotrop expedition to Zaire and Rwanda : 7., life strategies of epiphytic bryophytes from tropical lowland and montane forests, ericaceous woodlands and the Dendrosenecio subpáramo of the eastern Congo basin and the adjacent mountains (Parc National de Kahuzi-Biega/Zaire, Forêt de Nyungwe/Rwanda) [PDF]

, 1995
Life strategies of epiphytic bryophytes are studied along an altitudinal gradient from the eastern Congo basin (tropical lowland zone) to the mountains of the East-African graben (tropical subalpine/alpine Zone; BRYOTROP III-transect).

Nitrogen transfer from forage legumes to nine neighbouring plants in a multi-species grassland [PDF]

, 2012
Legumes play a crucial role in nitrogen supply to grass-legume mixtures for ruminant fodder. To quantify N transfer from legumes to neighbouring plants in multi-species grasslands we established a grass-legume-herb mixture on a loamy-sandy site in ...

Morphology and paleoecology of a hybodontiform with serrated teeth, Priohybodus arambourgi, from the Late Jurassic of northeastern Brazil

The Anatomical Record, EarlyView.
Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

Towards angiosperms genome evolution in time [PDF]

arXiv, 2013
In this communication, direction of evolutionary variability of parameters of genome size and structurally functional activity of plants in angiosperm taxa among life forms, are analysed. It is shown that, in the Cretaceous-Cenozoic era, the nuclear genome of the plants tended to increase.
