Early departures and delayed arrivals: Holocene dynamics of temperate tree species in the boreal‐temperate ecotone

open access: yesJournal of Ecology, Volume 113, Issue 9, Page 2460-2475, September 2025.
As temperate tree species require warmer temperatures than boreal species, some thermophilous species, such as white pine, increased in abundance at their northern edge during historically warmer periods. Our data reveal that not all temperate species behaved accordingly: maples were scarce during the warm mid‐Holocene, while their abundance increased ...

The Adaptive Significance of Tail‐Flagging: A Test in European Rabbits (Oryctolagus cuniculus)

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
European rabbits use their white tails to warn others of danger and ward off predators, revealing the dual function of a single animal signalling behaviour. Using both field observations and phylogenetic analyses, we show that tail‐flagging may alarm other rabbits before escape and deter predators during escape.

Evaluation of the genotoxic and teratogenic potential of a municipal sludge and sludge-amended soil using the amphibian Xenopus laevis and the tobacco: Nicotiana tabacum L. var. xanthi Dulieu [PDF]

open access: yes, 2003
The toxic, genotoxic and teratogenicpotential of amunicipal sewage sludge was assessed using the micronucleus assay on the larvae of the amphibianXenopuslaevis and with the tobacco somatic mutation test using the yellow–green xanthiDulieu mutant a1+/a1 ...

Characterization of soil fertility in Coffee (Coffea spp.) production areas in Côte d'Ivoire [PDF]

open access: yes, 2019
With the depletion of forest reserves, coffee growing based on extensive and shifting cultivation mode is no more reproductive. Thus, soils of different coffee growing areas were studied in order to diagnose the fertility level, their potential for ...

Ratio of natural isotopes of nitrogen. I. Primary results: soils of Dombes [Translation from: Revue d'Ecologie et de Biologie du Sol 14, 279-287, 1977]

open access: yes, 1980
Utilization of the heavy isotope of nitrogen as a tracer has found numerous applications in soil biology. It allows better definition of different stages of the nitrogen cycle, in particular the immobilization-mineralization cycle. In this work, the authors report the results of calculations of natural isotope ratios of nitrogen in samples of water ...
