Conservation Biology; a crisis science/
Biologia da Conservação: ciência da crise

Semina: Ciências Agrárias, 2002
The science of conservation biology has been developed as an answer to the extinction crisis the world is currently facing. Conservation Biology is a synthesis of many different subjects, like Ecology, Population Biology, Anthropology, Taxonomy, all of ...

Preliminary Assessment of Trace Metal Pollution and Their Bioaccumulation in Mollusks Inhabiting the Intertidal Sediments of the Atlantic Coast of Accra, Ghana

Journal of Toxicology, 2022
The present study investigated the trace metal levels in sediments, enrichment in sediments, and its bioaccumulation in mollusks collected from the intertidal sediments of the coast of Accra, Ghana, which is influenced by anthropogenic activities.

Milk microbiomes of three great ape species vary among host species and over time

Scientific Reports, 2022
In mammalian neonates, milk consumption provides nutrients, growth factors, immune molecules, and microbes. Milk microbiomes are increasingly recognized for their roles in seeding infant gut microbiomes and priming immune development.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Interactions between reproductive biology and microbiomes in wild animal species

Animal Microbiome, 2021
Many parts of the animal body harbor microbial communities, known as animal-associated microbiomes, that affect the regulation of physiological functions.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Patterns of genetic diversity in African forest elephants living in a human‐modified landscape in southwest Gabon

Conservation Science and Practice, 2019
We investigated the patterns of genetic diversity and structure of African forest elephants in a human‐modified landscape in the Gamba complex of protected areas (GCPA), a tropical wilderness area along the southwest coast of Gabon.
