The Atlantic semi-deciduous rainforest or "seasonal semideciduous forest," typically occurs as the riparian zone along riverbanks within the Cerrado biome. These forests form transitional ecotones between the open savanna vegetation of the Cerrado and the denser, humid Atlantic Forest proper🧪

Zygentoma Compound eyes, rhabdomeric photoreceptors (microvillar rhabdoms) for light detection (typical arthropod photoreceptor type)
No ocelli
Rely more on antennae/cerci than vision
Lepismatidae (silverfish) - small functional compound eyes
Nicoletiidae (soil/cave) - eyes greatly reduced/ absent

The transition of vegetation from the lowly water-stressed forest with high tree cover to a savanna-grassland regime with low tree cover and the utilization of rootzone storage capacity to cope with the spatial change to a drier climate.

Silvery-white covering are flattened, overlapping scales; give Zygentoma metallic appearance. Scales modified setae; provide protection, reduce water loss
Prominent bristles on head and body; sensory functions, detecting air movement and vibrations
Particularly concentrated around sensory organs 🧪

The Cerrado accounts for approximately 5% of the world's species, making it the most biodiverse savanna on Earth.
Between 1998-2008 alone, 347 new vertebrate species were described in the Cerrado (222 fish, 40 amphibians, 57 reptiles, 27 mammals, 1 bird).

Brazil's CERRADO: 2M km² savannah with 12,000+ plant species (45% endemic). Called "upside-down forest" - roots reach 20m deep, storing 60% of biomass underground. Fire-adapted biodiversity hotspot. 50% destroyed, only 3% protected. One of Earth's most threatened ecosystems. Science🧪

ZYGENTOMA: The living fossils of the insect world!

Known as silverfish, these apterygote insects (wingless) have existed for over 400 million years virtually unchanged. They're detritivores that feed on carbohydrates like cellulose and starch. 🧪

Brazilian Atlantic Forest harbors 23 Neoponera ant species! These remarkable predators serve as forest health indicators while producing antimicrobial venom compounds with potential medical applications. New species still being discovered in this biodiversity hotspot. 🧪

I can think of at least one hypothesis. This could involve Batesian mimicry, since Euglosini bees have stings that can be used as a defence against predators. The sting of a female Euglosini is less painful than that of a honey bee and, unlike honey bees, these bees can sting repeatedly.

Ornidia flies don’t just look like orchid bees—they ACT like them, mimicking bee behavior with similar wing buzz and leg movements! Worldwide, synanthropic. "Green Jewel Flies" help in determining time of death through predictable patterns on decomposing matter. #Evolution #ForensicScience

The microscope. Not this specific lens.

Macroarthropods @macroarthropods.bsky.social · Jul 18

I love the colours of old lenses photos

Some lenses, such as this Super-Takumar 1:1.4/50mm are slightly radioactive. For this one, the radioactive coat results in beautiful yellowish photos. 🧪
