Discordance of Dopaminergic Dysfunction and Subcortical Atrophy by α‐Synuclein Status in Sporadic and Genetic Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is characterized by predominantly neuronal α‐synuclein pathology and dopaminergic dysfunction. Cerebrospinal fluid (CSF) seeding amplification assays (SAA) detect α‐synuclein aggregates in vivo, but not all patients with PD have a positive SAA.

Change in liana density over 30 years in a Bornean rain forest supports the escape hypothesis

open access: yesEcosphere, 2021
Liana dynamics may influence tree dynamics and vice versa. Only long‐term studies can perhaps disentangle them. In two permanent plots of lowland dipterocarp forest at Danum, a liana census in 1988 was repeated in 2018.

Dicrananthera hedyotidea C. Presl. (Melastomataceae) in Maranhão state, Brazil: first record and ecological niche model of the species

open access: yesNordic Journal of Botany, EarlyView.
Dicrananthera C. Presl. is a monospecific genus of the tribe Marcetieae, comprising perennial herbs typically occurring in areas adjacent to wetlands. The species exhibits a disjunct distribution, with confirmed records in both the Amazon and Atlantic Forest domains.

Colonization of Mangrove Forest at Abandoned Shrimp-pond of Segara Anakan-cilacap [PDF]

open access: yes, 2014
During the 1996 to 1997, large areas of mangrove forest in the Segara Anakan were cleared and converted into intensive shrimp-ponds. After one to two years, these shrimp-ponds failed and were abandoned.

Taxonomic novelties in subgenus Euphorbia (Euphorbiaceae) from South India

open access: yesNordic Journal of Botany, EarlyView.
Extensive floristic explorations throughout southern India have uncovered some noteworthy taxonomic additions within the subgenus Euphorbia (Euphorbiaceae). Three distinct taxa of Euphorbia are described and illustrated herein as E. sankarensis, E. bahalita and E. tortilis var. mysorensis.

Plant and insect functional traits influence herbivore performance under climate change

open access: yesOikos, EarlyView.
Climate change is expected to disrupt many trophic interactions, including those between insect herbivores and their host plants, which could have detrimental effects at the ecosystem level. However, the response of insect herbivory to climate change can vary widely across species, and an understanding of the mechanisms underlying this variation is ...

The diversity and distribution of lianas under various disturbance regimes in Chilimo dry Afromontane forest, Ethiopia

open access: yesGlobal Ecology and Conservation, 2020
Lianas contribute substantially to plant diversity and to local people’s livelihood in tropical forests around the world. However, their species composition and the factors that determine their distribution in dry Afromontane forests are less explored ...

Sparse halves in dense triangle-free graphs [PDF]

open access: yes, 2015
Erd\H{o}s conjectured that every triangle-free graph $G$ on $n$ vertices contains a set of $\lfloor n/2 \rfloor$ vertices that spans at most $n^2 /50$ edges.

Unraveling the spatial landscape of dystrophinopathies: a transcriptomic approach to Becker and Duchenne muscular dystrophies

open access: yesThe Journal of Pathology, EarlyView.
Abstract Dystrophinopathies are caused by pathogenic variants in the DMD gene, resulting in partial (Becker) or complete loss (Duchenne) of dystrophin. Becker (BMD) and Duchenne muscular dystrophy (DMD) are characterized by progressive muscle wasting, fatty replacement, fibrosis, and loss of function.
