Coordination of cortex modifications in time, space, and under stress. [PDF]
New PhytolSummary In roots, cell‐type‐specific differentiation enables specialized responses to environmental stress. The cortex, located between the vasculature and epidermis, is a key site for stress‐responsive modifications. The distinct specializations of the cortex are controlled by developmental, positional and environmental signals.

Human-Induced Downsizing of Animal Communities Weakens Trait Matching Between Tropical Plants and Frugivores. [PDF]
Ecol LettWe assess the impact of human‐induced ‘downsizing’ of animal communities on plant–frugivore trait matching—the alignment between fruit size and frugivore body mass—using a global dataset on plant and animal traits and 102 ecological networks across the tropics.

Robust activity-dependent mitochondrial calcium dynamics at the AIS is dispensable for action potential generation. [PDF]
J PhysiolAbstract figure legend In cortical layer (L)5 pyramidal neurons we found that mitochondria in the axon initial segment (AIS) are distributed non‐uniformly and display robust calcium (Ca2+) uptake during action potential (AP) firing. Because the AIS is the site for the initiation of APs, which are shaped by cytosolic Ca2+ levels, we hypothesized that ...

Ecological predictors of plant responses to sequential herbivory: a meta-analysis. [PDF]
New PhytolSummary Plants evolved alongside herbivores for over 400 million years and show remarkable plasticity in responses to attack by multiple herbivores. However, it is often debated which herbivore traits predict plant responses and it is poorly understood how plant life‐history traits contribute to the variation observed in plant responses.

First Measurements of Mixed Floral Traits Influencing <i>Anacardium occidentale</i> (Anacardeacae) Attractiveness to Bees in Côte d'Ivoire: Conservation and Agricultural Implications. [PDF]
Ecol EvolThis paper will contribute to include/use the bees' floral preference (floral traits related to bee' visitations) to find and validate genetic markers that would enable breeding high‐yielding cashew plants and preserving pollinators. ABSTRACT In Sub‐Saharan Africa, cashew plants face challenges in suitable pollination and good agronomic performances ...

How chronic anthropogenic noise can affect wildlife communities
Frontiers in Ecology and Evolution, 2023 Anthropogenic noise is a major pollutant in terrestrial and aquatic ecosystems. Since the industrial revolution, human activities have become increasingly noisy, leading to both acute and chronic disturbance of a wide variety of animals.

The Thomisidae and Philodromidae (Arachnida: Araneae) of the Galápagos Islands (Ecuador) [PDF]
, 2013 Two new species of Thomisidae are described (Mecaphesa reddelli sp. nov. and Tmarus galapagosensis sp. nov.). Of a third species, Mecaphesa inclusa (Banks, 1902), three colour variations are described.

A new Oligocene site with terrestrial mammals and a selachian fauna from Minqar Tibaghbagh, the Western Desert of Egypt [PDF]
Acta Palaeontologica Polonica, 2017 A new fossil site at Minqar Tibaghbagh, east of Siwa, in the Egyptian Western Desert is described. This represents the first place in Egypt outside the Fayum Depression yielding Paleogene, terrestrial mammals.
