The mid-Miocene Zhangpu biota reveals an outstandingly rich rainforest biome in East Asia

Science Advances, 2021
The Zhangpu biota provides a new insight into biodiversity redistribution during the Mid-Miocene Climatic Optimum. During the Mid-Miocene Climatic Optimum [MMCO, ~14 to 17 million years (Ma) ago], global temperatures were similar to predicted ...

Transboundary priorities for protection of frigatebird non-breeding habitat in a heavily impacted region

Global Ecology and Conservation, 2021
Species that inhabit spatially-distinct regions at different stages of their lifecycle pose challenges to conservation managers, particularly when distributions span international or jurisdictional boundaries.

Amazon rainforest photosynthesis increases in response to atmospheric dryness

Science Advances, 2020
Models show that increasing air dryness reduces photosynthesis in the Amazon rainforest, while observations show the opposite. Earth system models predict that increases in atmospheric and soil dryness will reduce photosynthesis in the Amazon rainforest,

Population collapse in Congo rainforest from 400 CE urges reassessment of the Bantu Expansion

Science Advances, 2021
Settlement of the Central African rainforest before transatlantic slave trade was not a continuous but spread-over-spread process. The present-day distribution of Bantu languages is commonly thought to reflect the early stages of the Bantu Expansion, the

Global restoration opportunities in tropical rainforest landscapes

Science Advances, 2019
Assessment of socioenvironmental benefits and feasibility identifies priority areas for restoring global tropical rainforests. Over 140 Mha of restoration commitments have been pledged across the global tropics, yet guidance is needed to identify those ...

Heteroleptic and Homoleptic Iron(III) Spin-Crossover Complexes; Effects of Ligand Substituents and Intermolecular Interactions between Co-Cation/Anion and the Complex

Inorganics, 2017
The structural and magnetic properties of a range of new iron(III) bis-tridentate Schiff base complexes are described with emphasis on how intermolecular structural interactions influence spin states and spin crossover (SCO) in these d5 materials.

New records of Dipsas welborni Arteaga & Batista, 2023, Gelanesaurus flavogularis (Altamirano-Benavides, Zaher, Lobo, Grazziotin, Sales-Nunes & Rodrigues, 2013), and Synophis insulomontanus Torres-Carvajal, Echevarría, Venegas, Chávez & Camper, 2015 in the Cordillera de Colán, Peru [PDF]

Check List
A herpetological survey during recent expeditions to the foothills of the Cordillera de Colán in the Amazonas region of Peru resulted in new records and extensions of the geographical distribution of three poorly known species of reptiles ...

Quantifying the Aerodynamic Power Required for Flight and Testing for Adaptive Wind Drift in Passion-Vine Butterflies Heliconius sara (Lepidoptera: Nymphalidae)

Insects, 2023
Although theoretical work on optimal migration has been largely restricted to birds, relevant free-flight data are now becoming available for migratory insects. Here we report, for the first time in passion-vine butterflies, that Heliconius sara migrates

Record-breaking warming and extreme drought in the Amazon rainforest during the course of El Niño 2015–2016

Scientific Reports, 2016
The El Niño-Southern Oscillation (ENSO) is the main driver of interannual climate extremes in Amazonia and other tropical regions. The current 2015/2016 EN event was expected to be as strong as the EN of the century in 1997/98, with extreme heat and ...
