On the distribution of gymnosperm genera, their areas of endemism and cladistic biogeography [PDF]

open access: yes, 2002
A distributional analysis of 81 gymnosperm genera was undertaken. On the basis of the congruence in the distribution of these genera, nine areas of endemism were recognised.

Repetitive Elements, Sequence Turnover and Cyto-Nuclear Gene Transfer in Gymnosperm Mitogenomes [PDF]

open access: yes, 2022
Among the three genomes in plant cells, the mitochondrial genome (mitogenome) is the least studied due to complex recombination and intergenomic transfer.

The most threatened plants receive the least scientific attention

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Plants sustain all life, providing the energetic and structural basis of ecosystems, but they face a growing risk of extinction. Reversing this decline requires an understanding of how scientific knowledge is distributed among species, and identification of the biases and gaps that hinder effective responses to the threats they face. However, we reveal

Microsatellite analysis reveals significant genetic differentiation and conservation challenges in the threatened conifer Amentotaxus yunnanensis H. L. Li

open access: yesEnvironmental Research Communications
Habitat loss due to deforestation and overexploitation are major causes threatening the long-term survival of Amentotaxus yunnanensis , a vulnerable conifer native to Vietnam.

The complete mitochondrial genome of Taxus cuspidata (Taxaceae): eight protein-coding genes have transferred to the nuclear genome

open access: yesBMC Evolutionary Biology, 2020
Background Gymnosperms represent five of the six lineages of seed plants. However, most sequenced plant mitochondrial genomes (mitogenomes) have been generated for angiosperms, whereas mitogenomic sequences have been generated for only six gymnosperms ...

Response of Fecal Bacteria and Fungi to Tannin‐Rich Diets in Sika Deer (Cervus nippon): Evidence from Both Feeding Experiments and Field Investigations

open access: yesIntegrative Zoology, EarlyView.
Feeding with tannin‐rich diets altered the fecal microbial composition and increased the relative abundance of tannin‐degrading microbes. We hypothesize that fecal bacteria and fungi may play important roles in helping herbivores adapt to tannin‐rich diets but respond to different tannin concentrations varies.

Living on the edge – physiological tolerance to frost and drought explains range limits of 35 European tree species

open access: yesEcography, EarlyView.
Species distribution models are key to evaluate how climate change threatens European forests and tree species distributions. However, current models struggle to integrate ecophysiological processes. Mechanistic models are complex and have high parameter requirements.

Richness and Current Status of Gymnosperm Communities in Aguascalientes, Mexico [PDF]

open access: yes, 2017
The gymnosperm diversity of Aguascalientes, Mexico, is presented. Fifteen species from five genera and three families are reported, two of Coniferales (Cupressaceae and Pinaceae) and one of Gnetales (Ephedraceae).
