Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis

Integrative Zoology, EarlyView.
Cromileptes altivelis exhibits a distinctive “sunken head and humpback” morphology, formed through cranial remodeling. Genetic analyses identified unique amino acid variants in Hoxa7a and Hoxa10b, with functional tests confirming their role in enhancing osteoblast activity and driving cranial remodeling.

Microbial and transcriptional response of Acropora valida and Turbinaria peltata to Vibrio coralliilyticus challenge: insights into corals disease resistance

BMC Microbiology
Background Coral diseases are significant drivers of global coral reef degradation, with pathogens dominated by Vibrio coralliilyticus playing a prominent role in the development of coral diseases.

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans

Integrative Zoology, EarlyView.
Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

Goby gummies: A customizable and edible assay to quantify predation in aquatic ecosystems

Methods in Ecology and Evolution, EarlyView.
Abstract Predation is a critical ecosystem process that shapes the structure and functioning of biological communities. However, due to its intermittent nature, fast pace and general unpredictability, predation is difficult to observe and quantify. Therefore, we commonly rely on indirect metrics or proxies of predation, which reflect the outcome of ...

Inferring alternative ecosystem states with field survey data

Methods in Ecology and Evolution, EarlyView.
Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Major transitions in early coral development: novel insights enabled by visualisation of a comprehensive transcriptomic dataset for Acropora millepora

BMC Biology
Background Given the ecological importance of reef-building corals (Scleractinia), it is perhaps surprising that the molecular mechanisms underlying many of the morphological and metabolic changes during their development remain unclear. In part, this is

Adaptive Spaces and Rural Futures: Climate Change, Agrarian Dynamics, and Knowledge Politics in Southeast Asian Socioecological Transformations

Asia Pacific Viewpoint, EarlyView.
ABSTRACT Contemporary rural change in Southeast Asia is shaped by complex, intersecting forces that defy simplistic narratives. Researchers must therefore develop new ways to grasp nuanced, non‐linear, and locally specific processes to understand how transformational shifts may occur (or not) in the region.

Indigenous‐Led Adaptation to Complex Climate Risks in New Ireland, Papua New Guinea

Asia Pacific Viewpoint, EarlyView.
ABSTRACT Pacific Island peoples have long histories of adapting to environmental changes, but recent climate change is now driving complex risks that unfold within rapidly shifting societal and environmental contexts. This study investigates how remote Indigenous communities in New Ireland, Papua New Guinea, experience and want to respond to complex ...

Assessing the consistency and reliability of the line intercept transect method in coral cover estimation using structure from motion photogrammetry techniques

Geocarto International
Appropriate coral reef monitoring methods and descriptors determine the effectiveness of ecosystem status assessment. We combined line intercept transect (LIT) and SfM technologies for image acquisition, and the POS information of images is defined and ...

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

Archaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.
