A zoogeographic model for the evolution of diversity and endemism in Madagascar
The delineation of zoogeographic regions is essential for understanding the evolution of biodiversity. Madagascar, characterized by high levels of endemism and habitat diversity, presents unique challenges and opportunities for such studies. Traditional global zoogeographic classifications, largely based on vertebrates, may overlook finer‐scale ...

How many trees are there in the North American boreal forest?
Boreal forests, the largest terrestrial biome on Earth, are highly varied in local tree density. Despite previous attempts to estimate tree density in boreal forests, the accuracy of the estimation is unknown, leaving the question how many trees there are in boreal forests largely unanswered. Here, we compiled tree density data from 4367 plots in North

Orthodontic movement in deciduous teeth [PDF]
Deciduous teeth exfoliate as a result of apoptosis induced by cementoblasts, a process that reveals the mineralized portion of the root while attracting clasts. Root resorption in deciduous teeth is slow due to lack of mediators necessary to speed it up; however, it accelerates and spreads in one single direction whenever a permanent tooth pericoronal ...

Populations at the edge of a species' distribution often encounter more challenging environmental conditions than those at the core, requiring unique adaptations and strategies. However, the demographic processes driving these populations remain poorly understood.

Williams-Beuren Syndrome: A Case Report
Williams syndrome is a rare neurodevelopmental disorder caused by the spontaneous deletion of genetic material from the region q11.23 of one member of the pair of chromosome 7, so that the person is hemizygous for those genes.

Settling aerodynamics is a driver of symmetry in deciduous tree leaves [PDF]
Leaves shed by deciduous trees contain 40\% of the annually sequestered carbon, and include nutrients vital to the expansion and health of forest ecosystems. To achieve this, leaves must fall quickly to land near the parent tree -- otherwise, they are lost to the wind, like pollen or gliding seeds. However, the link between leaf shape and sedimentation

Abstract This study investigates the composition of smoke gases in forest and vegetation samples to draw conclusions about the actual smoke gas composition during wildfires. The focus is particularly on regions with extensive pine forests, like in Eastern Germany.

. Climatic changes in the northeastern US are expected to cause coniferous stands to transition to deciduous stands over the next hundred years. Mercury (Hg) sequestration in forest soils may change as a result.

How to Approach the Definition of WUI in Northern Europe
ABSTRACT This article aims to delineate the wildland–urban interface in the sparsely populated, limited‐resourced Scandinavian peninsula (excluding Finland). Common WUI mapping assumptions and how different thresholds capture the reality of building ignition from wildfire in this region are evaluated.
