We evaluated the effect of ENSO 2015/16 on the water relations of eight tree species in seasonally dry tropical forests of the Yucatan Peninsula, Mexico. The functional traits: wood density, relative water content in wood, xylem water potential and specific leaf area were recorded during the rainy...

This contribution is part of a series devoted to the phylogeny and taxonomy of powdery mildews, with an emphasis on North American taxa. An overview of Cystotheca species is given, including references to ex-type sequences or, if unavailable, proposals for representative reference sequences for...

This review of Neotropical Burseraceae emphasizes developments since the last major review of the family in 2011. The Burseraceae comprise a Laurasian group (represented by Eocene fossils in the Northern Hemisphere) that originally dispersed through Central America into Amazonia. During cooling and ...

Given the outstanding global progress of research on the hydraulic pathway in plants, and its important role as an indicator of plant mortality risk, we reviewed: (1) the adaptive basis of hydraulic traits and their importance for overall plant function; (2) the number of primary scientific...

We describe two new fossil woods from the San Carlos Formation (Upper Cretaceous), Chihuahua State, Mexico. The first wood resembles the fossil genus Metcalfeoxylon in having solitary vessels, scalariform perforation plates, vessel-ray parenchyma pits of similar size as the intervessel pits, axial...

Oaks are a dominant woody plant genus in the northern hemisphere that occupy a wide range of habitats and are ecologically diverse. We implemented a functional trait approach that included nine functional traits related to leaves and stems in order to explain the species coexistence of 21 oak...

Hydnobolites oaxacanus is described using molecular and morphological data. This new species is characterized by the whitish ascomata with orange spots, grey gleba, and 4-spored asci with ascospores of 17-45 × 15-20 µm. The new species differs from other American Hydnobolites such as H....

Lasiocarpus is a genus of bisexual, dioecious, or trioecious shrubs or small trees of Malpighiaceae endemic to the seasonally dry tropical forests of the Pacific slopes of Mexico. In this paper the monophyly of this genus is tested using a molecular phylogeny based on three plastid (ndhF, matK, ...

At the regional scale, abiotic environmental heterogeneity related to elevation and climatic profiles influences patterns of diversity and species composition. At the local scale, little is known about the influence of biotic environmental heterogeneity (habitat diversity) on the diversity,...

The growth and development of a plant is highly dependent on the availability of soil moisture, soil nutrients and water content in the plant cell. The plant cell requires 85-89% water to maintain its dynamic vital activity and enzymatic processes. Therefore, there is a great necessity to maintain...
