The Polydora complex is a globally widespread polychaete parasite known for secreting acidic substances to bore tunnels into oyster shells. This process leads to the formation of dark brown crusts on the inner shell surface, a condition commonly referred to as “black shell disease”. Not only does this disease degrade the quality of shellfish, but it also causes substantial mortalities, with the Hong Kong oyster ( Crassostrea h...

Perkinsus spp. are pathogenic protistan parasites that pose a significant threat to the aquaculture of the Hong Kong oyster ( Crassostrea hongkongensis ). This study investigated the transcriptional response of the Hong Kong oyster digestive gland to natural Perkinsus spp. infection. The parasite species was identified via PCR, while infection prevalence, tissue‐specific abundance, and infection grade were assessed using Ray's...

Uncovering the mechanisms that lead to Amazon forest resilience variations is crucial to predict the impact of future climatic and anthropogenic disturbances. Here, we apply a previously used empirical resilience metrics, lag‐1 month temporal autocorrelation (TAC), to vegetation optical depth data in C‐band (a good proxy of the whole canopy water content) in order to explore how forest resilience variations are impacted by hum...

Classical major histocompatibility complex (MHC) class II molecules play an essential role in immune system. In this study, MHC II α (Pf‐MHC II α ) and MHC II β (Pf‐MHC II β ) homology genes from pufferfish ( Takifugu obscurus ) were cloned and their functional characterization in response to bacterial challenge was identified. The nucleotide sequences of the open reading frames (ORFs) of pufferfish Pf‐MHC IIα and Pf‐MHC IIβ w...
