A critical discovery of the Critically Endangered catfish <em>Trichogenes claviger</em>, endemic to Brazil's Atlantic Forest, expands its known range by over 18 times, from 8 km² to 16 km². Initially described in 2010, this species was thought to be confined to a single, highly threatened locality until recent observations confirmed its presence across multiple sites within the Mata de Kaetés Private Natural Heritage Reserve and surrounding areas. The study highlights the pivotal role of local communities and conservation units in identifying and protecting threatened biodiversity, including the identification of nursery grounds harboring hundreds of individuals. This finding underscores the importance of community engagement and targeted mapping efforts for species preservation in Brazilian biodiversity hotspots.

A groundbreaking discovery in the conservation of ancient artifacts reveals that all identified mummies from the 18th through 21st Dynasties, except Tutankhamun's, were successfully reburied in secret caches (KV 35 or TT 320) during Butehamon's tenure as royal scribe and overseer of the treasury under Pinudjem I. This study sheds light on the historical significance of these caches, which not only preserved royal mummies but also facilitated the plundering of valuables for priestly rulers. The research employs a meticulous analysis of original materials and techniques used in construction, providing insights into both the history of the Theban necropolis and the nature of past and current deterioration problems. This approach offers a unique perspective on the end of the New Kingdom's tomb-making era and the transition to mummy reburial practices.

A novel conservation approach for the mural paintings at Amenemhat's tomb (TT 340) in Deir el-Medina, Western Thebes, Egypt, has been successfully demonstrated. The study identified Klucel G 1% as highly effective for consolidating weak painting layers and Bio Estel for fragile mud plaster layers. Additionally, a specific mortar blend was found suitable for filling gaps and cracks, significantly advancing the preservation of ancient Egyptian tempera techniques. The research employed advanced analytical methods including SEM-EDS, XRD, FTIR, and colorimetric measurements to assess the current state and determine optimal conservation materials. This work provides critical insights into the long-term preservation of UNESCO World Heritage Sites with similar deterioration factors.

Successful management of invasive Purple Swamphens on Phillip Island significantly boosted breeding success of Kermadec Petrels from 25% to 56%, highlighting the critical impact of predator control on seabird conservation. The study identified that these surface-nesting petrels prefer sloping terrain (182–228 m above sea level) within 85 m of the coast, under low scrubby woodland, and exhibit year-round breeding with a peak in late austral spring. Prudent management of this population could support regional recovery efforts, including potential reintroduction to Lord Howe Island, while also aiding island restoration through increased marine-derived nutrient transfers. Adaptive management strategies will be essential to mitigate threats from native avian predators.
