Residuos de pesticidas organoclorados en yema de huevo (I)
, 1979 The incidence of several organochlorinated pesticides in fifty poultry eggs yolk, has been investigated. The sampling for this study has been radomly performed from a comercial channel of the local market. The incidence of lindane, heptachlor, aldrin, dieldrin, p-p"DDE, p-p"TDE and p-p"DDT has been observed with 6, 8, 38, 49, 49, 6 and 49 of fifty ...

New Phytologist, Volume 250, Issue 6, Page 3646-3660, June 2026.Field sampling sites and mesocosm experimental design. Summary Increasing frequency and intensity of droughts threaten grassland ecosystems. Semi‐natural grasslands vary in age from ancient to younger sites established on former arable land. While species richness and composition are known to affect drought resilience, little is known about how ...

Reduced snow cover at the alpine treeline: resistance and recovery of saplings
New Phytologist, Volume 250, Issue 3, Page 1492-1509, May 2026.Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

Cold hardiness dynamics predict budbreak and associated low‐temperature threats in grapevine
New Phytologist, Volume 250, Issue 4, Page 2203-2220, May 2026.Summary Dormant buds of temperate woody perennial plants must attain cold hardiness to survive winters and timely lose it in spring to break bud while avoiding damage from low temperatures and late frosts. Therefore, we asked: Can a cold hardiness model be used to predict budbreak?

PEP725: 15 years of driving European and global phenology science
New Phytologist, Volume 250, Issue 2, Page 717-734, April 2026.Summary Phenology – the timing of seasonal biological events – is a sensitive indicator of climate change and ecosystem dynamics. Long‐term, broad‐scale phenological data are crucial for understanding and predicting plant responses to environmental change.
