Detecting Pteridium arachnoideum and Tithonia diversifolia in a Multiclass Land‐Cover Framework in the Cerrado: A Deep Learning Time‐Series Benchmark With Spatial Cross‐Validation

open access: yesTransactions in GIS, Volume 30, Issue 2, April 2026.
ABSTRACT This study presents the first deep‐learning time‐series benchmark for detecting two encroaching species in the Brazilian Cerrado: the native super‐dominant fern Pteridium arachnoideum and the invasive alien shrub Tithonia diversifolia. We evaluate 43 architectures across six families (CNNs, RNNs, Transformers, and three hybrid groups) on ...

Contaminação por metais traço em mexilhões Perna perna da costa brasileira Trace metal contamination in mussel Perna perna from Brazilian coast

open access: yesCiência Rural, 2013
Os metais traço apresentam grande toxicidade quando presentes em teores elevados nos organismos humano e animal. No ambiente aquático, alguns elementos formam compostos orgânicos que bioacumulam nos tecidos de organismos vivos. Os moluscos bivalves se destacam, pois possuem grande participação na dinâmica de contaminantes metálicos no ambiente marinho ...

The skeletal muscle–adipose creatine metabolic axis: A novel paradigm for lipid metabolism reprogramming and obesity management

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 1700-1707, 1 April 2026.
Abstract The global prevalence of obesity and related metabolic disorders has spurred interdisciplinary research to develop new intervention strategies. Current research is increasingly focusing on the exercise‐induced browning of white adipose tissue and the mechanisms by which it improves energy metabolism.

Fouling organisms on Perna perna mussels: is it worth removing them?

open access: yesBrazilian Journal of Oceanography, 2007
Perna perna mussel spat were suspended from ropes on a long-line cultivation, at Coqueiro´s Beach, Anchieta, South-eastern Brazil, in order to quantify the fouling community structure and its effects on growth and biomass of mussels.

The Different Capability Of Metal Uptake In The Shell Of Perna Viridis Compared To The Different Soft Tissues: A Statistical Approach [PDF]

open access: yes, 2009
Distribution of metals in bivalves is usually examined based on different metal concentrations in the different tissues of the bivalves. Patterns of metal distribution between the shells and the different soft tissues of two geographical populations of ...

Evidence for the main foot protein gene in Perna perna (Mollusca, Mytilidae)

open access: yesGenetics and Molecular Research, 2008
Here, we investigated the gene that encodes the main protein component of the byssus in Perna perna (Ppfp) using a consensus fluorescent probe for the Mytilus group and by polymerase chain reaction amplification using specific and random primers. A 524-bp fragment resulting from polymerase chain reaction amplification was found to be homologous to the ...

Neurons characterization in the cerebral ganglia of the green-lipped mussel, Perna canaliculus, using antibodies raised against neuropeptides and neurotransmitters involved in gastropod egg-laying behaviour and bivalve reproduction and spawning [PDF]

open access: yes, 2007
Immunohistochemical techniques were used to characterise central neurons in the cerebral ganglia of both male and female Perna canaliculus. We used mollusc antibodies raised against neuropeptides and neurotransmitters known to control reproduction and ...

Genetic characterization and protein profiling of green mussel (Perna viridis (Linnaeus, 1758)) and brown mussel (Perna indica Kuriakose and Nair, 1976) [PDF]

open access: yes, 2008
The marine mussels of India are mainly of two species: Perna viridis [Linnaeus, 1758) (green mussel) and Perna indica Kuriakose and Nair (1976) [brown mussel).
