🌍 Conservation conclusions:
✅ Protecting connectivity between parks and water bodies is key.
✅ Planting tall native trees promotes higher functional diversity.
✅ Creating ecological corridors between small and large parks supports species dispersal. #EcologicalRestoration

🦋 How do small or fragmented parks affect butterflies?
Smaller and fragmented parks show lower diversity and more homogenized species assemblages.
⚠️ We need parks with native vegetation and proximity to water bodies to promote biodiversity!

🌳 What influences butterfly diversity in urban parks?
✔️ The height of native trees is strongly associated with functional diversity.
✔️ Connectivity between parks enhances both taxonomic and functional diversity.

🌱 Why is it important?
Preserving Amazonian ecosystems requires enhancing forest connectivity and restoring native vegetation at the forest edges to mitigate the negative impacts of habitat fragmentation. 🐸🌐

✔️ Forest edges act as ecological filters, limiting the colonization of pasture species into forest interiors via environmental gradients and functional competition.
September 2, 2025 at 5:46 PM
✔️ In pastures, environmental filtering plays a major role in shaping amphibian assemblages, while limiting similarity governs the assemblage in forest interiors.
✔️ Functional diversity is more influenced by landscape connectivity, leaf litter depth, and humidity rather than edge effects alone

🌱💡 What role do functional pollinator ecology studies play in adaptation to socio-environmental change? How can we integrate this scientific knowledge into public policies? #ScientificEducation #SocialChange #EnvironmentalPolicy #Pollination #Ecology

💡 Functional traits related to the amount of body hair in bees, which aid in pollen adhesion, showed no correlation with the total pollen amount, nor with granadilla pollen. #FunctionalTraits #Pollination #Biodiversity #Bees #Sustainability

🐝 The invasive species Apis mellifera, while the most abundant and large-bodied bee, DOES NOT carry pollen from native species nor from granadilla, making it a POOR pollinator for these crops. #Pollination #ApisMellifera #InvasiveSpecies #Ecology #Biodiversity

🔬 Body size in NATIVE bees is crucial for efficient pollen transport. Studies on insect pollinators can boost productivity and protect biodiversity. 🌻📚 #Sustainability #Pollinators #Ecology #AgriculturalEcology #Biodiversity

1. Anuran diversity was more influenced by landscape configuration (e.g., number of patches, water bodies) than composition.
2. Abundance was linked to structurally complex vegetation (e.g., rosettes, scrublands).

✔️ At 50m, larger contiguous habitats increased abundance, while fragmentation reduced it.
✔️ At 100m to 200m water bodies and scrubby vegetation like Chusquea spp. were key for species persistence, such as Dendropsophus molitor, which need water for larval development. @amphibianspecies.bsky.social

✔️ Landscape configuration is a crucial factor for species persistence.
✔️ Limited mobility: Species success depends on their movement between vegetation mosaics in these high-altitude ecosystems.
✔️ Conservation efforts should focus on maintaining connectivity and vegetation complexity.

✔️ Landscape configuration (number of water bodies, patches of dense scrub with Chusquea spp.) had a greater impact on anuran diversity than habitat composition.
✔️ Abundance: Positive correlation with complex vegetation types like rosettes and dense scrublands.

🔍 Conserving permanent, shaded water bodies surrounded by intact forest is key for protecting larval amphibians like E. bivocata.
🌿 Changes in vegetation cover alter pond microhabitats and reduce their suitability.

Lithobates vaillanti inhabits ponds in secondary vegetation and in recently cleared forest areas with silty substrate and leaf litter in secondary/tallied forest (24°C)

🌿 Species-specific pond preferences in rainforest:
✔️ Exerodonta bivocata: permanent ponds with flow, rocks, and decapods in shaded primary forest (22°C)
✔️ Incilius valliceps: temporary ponds without predators, pH 7.2, in secondary forest with branches and litter
