Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1476-1499, September 2026.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

The potential effect of megafaunal extinctions on modern conservation of horse chestnut Aesculus hippocastanum

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1563-1566, September 2026.
Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

Road air pollution harms the reproductive success of a bee‐pollinated wildflower: A dusty threat to biodiversity

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1567-1571, September 2026.
Dust, a common form of air pollution, is particularly problematic on roadsides, which are important habitats for plants and pollinators. We investigated whether and how road dust affects plant sexual reproduction using Primula chungensis in a biodiversity hotspot. Our study provides compelling evidence that road dust can harm plant reproductive success

USING STUDY PAGES IN A BILINGUAL DICTIONARY IN GERMAN LANGUAGE CLASSES

open access: yesMetodički Vidici, 2013
The starting point is the assumption that bilingual dictionaries are not used very often during German language classes. The influence of electronic media results in the fact that paper dictionaries are not in use and students do not know how to make use

The Effect of Some Forage Additives Used in Feeding of Weaned Pigs

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The experiment was carried out over a group of 50 weaned piglets, allotted into two equal groups The control group (C) received a basal diet supplemented with a 2% premix – vitamins and microelements as oxides and salts mixed with maize flour-based diet;

Small‐scale adaptation to geothermal soil heating in a perennial herb revealed by combining crosses and transplantations

open access: yesNew Phytologist, Volume 251, Issue 5, Page 3008-3020, September 2026.
Path diagrams showing the results of piecewise structural equation models examining how fitness (total number of seeds in flowering individuals) of Cerastium fontanum depended on temperature at planting site, temperature difference, mating type, and flowering time (FFD, first flowering date) in each of the two study years.

The incredible vulnerability that reproduction poses for plant species in a warming world

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3111-3118, September 2026.
Generalized plant responses to heat stress across whole‐plant and reproductive scales. Summary Temperatures are rising globally and threatening the persistence of natural plant populations. Elevated temperatures disrupt gametogenesis, fertilization, and seed filling, often at lower thresholds than those affecting photosynthesis, growth, or survival ...
