Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3515-3545, December 2022., 2022 Glacial geomorphology and postglacial landforms, derived from LiDAR‐based digital terrain models, together with radiocarbon‐dated sediment sequences, form the basis for landscape reconstruction spanning c. 2000 years (10,500–8500 cal. bp). After formation of streamlined terrain and ribbed moraine tracts followed intense glaciofluvial activity at ...

The Pollination of the Primrose [PDF]
Nature, 1909 IN NATURE of May 20 the reviewer, in the course of his appreciative and interesting notice of my book, “Life-histories of Familiar Plants,” states:—“We notice that, without stating definitely what insect pollinates the primrose, the author refers to the bee or moth as doing it, in a misleading way. He would have been wiser to ask readers to notice what

Continuous limits of large plant-pollinator random networks and some applications [PDF]
arXiv, 2022 We study a stochastic individual-based model of interacting plant and pollinator species through a bipartite graph: each species is a node of the graph, an edge representing interactions between a pair of species. The dynamics of the system depends on the between- and within-species interactions: pollination by insects increases plant reproduction rate

Flower Pollination Algorithm for Global Optimization [PDF]
Unconventional Computation and Natural Computation 2012, Lecture
Notes in Computer Science, Vol. 7445, pp. 240-249 (2012), 2013 Flower pollination is an intriguing process in the natural world. Its evolutionary characteristics can be used to design new optimization algorithms. In this paper, we propose a new algorithm, namely, flower pollination algorithm, inspired by the pollination process of flowers.

Earth Surface Processes and Landforms, Volume 48, Issue 1, Page 198-214, January 2023., 2023 The Atlantic coast of NW Spain, where shingle beaches appear today, has suffered an important mobilization of dunes from a sea level about −120 m (bpsl), 20 ky ago. This aeolization caused the collapse of coastal/fluvial ecosystems (as forests) until the Late Holocene.

Linking Land Cover Data and Crop Yields for Mapping and Assessment of Pollination Services in Europe
Land, 2013 Pollination is a key ecosystem service as many crops but in particular, fruits and vegetables are partially dependent on pollinating insects to produce food for human consumption.
