A Guide to Integrate Plant Cover Data From Two different Methods [PDF]
, 2020 There is a lack of consensus on how to monitor (measure) plant cover in tidal marshes. Multiple methods exist to estimate plant cover, which can confound interpretation when making comparisons across methods.

Reactive glass and vegetation patterns [PDF]
, 2002 The formation of vegetation patterns in the arid and the semi-arid climatic zones is studied. Threshold for the biomass of the perennial flora is shown to be a relevant factor, leading to a frozen disordered patterns in the arid zone. In this ``glassy'' state, vegetation appears as a singular plant spots separated by irregular distances, and an ...

The effect of vegetation patterns on Aeolian mass flux at regional scale: a wind tunnel study [PDF]
, 2012 Although insight on the effect of vegetation pattern on Aeolian mass transport is essential for re-planting degraded land, only limited knowledge on this effect is available.

American Journal of Botany, EarlyView.Abstract Premise Amphistomy, the presence of stomata on both leaf surfaces, can increase photosynthesis yet is uncommon across vascular plants. The relative infrequency of amphistomy is often attributed to high costs, such as transpirational water loss.

Une opérade anticyclique sur les arbustes [PDF]
arXiv, 2009 We define new combinatorial objects, called shrubs, such that forests of rooted trees are shrubs. We then introduce a structure of operad on shrubs. We show that this operad is contained in the Zinbiel operad, by using the inclusion of Zinbiel in the operad of moulds.

Stand-level drivers of tree-species diversification in Mediterranean pine forests after abandonment of traditional practices [PDF]
, 2015 The progressive abandonment of traditional forest management over the last few decades has led to significant densification processes in most Mediterranean pine stands.

American Journal of Botany, EarlyView.Abstract Premise Establishment of long‐lived perennial plants is a pivotal event that often leads to reproductive maturity. The population dynamics of the giant saguaro cactus (Carnegiea gigantea) have been investigated over large spatial areas, but establishment patterns have not been studied at the microsite (1 m) scale.
