Short- and long-term effects of social hierarchy level on seminal quality and behavior traits in goat bucksNARA Subscribed
Social hierarchy affects semen quality and social interactions in males. However, the long-term effects of social hierarchy on semen quality, sexual, and social traits in goat bucks are unknown. Goat bucks were assigned to the dominant and subordinate groups. Semen quality, sexual, and social behavior traits were evaluated every other day for six days to establish a short-term effect, and every week for 25 weeks to establish a...
A balanced approach to the potential of octopus aquacultureNARA Subscribed
Species with high connectivity usually lack genetic differentiation. We tested for the presence of multiple populations of jumbo squid ( Dosidicus gigas ) on the Southeastern Pacific Ocean. Samples were collected from Ecuador to southern Chile (1.5° S–38° S). Two mitochondrial genes were sequenced (COI and ND2). Jumbo squids from all sampled locations in Ecuador, Peru, and Chile, as a whole, were characterized by low genetic d...
Pineapple mealybug wilt-associated viruses 1, 2, and 3 are associated with mealybug wilt disease of pineapple in PeruNARA Subscribed
Mealybug wilt of pineapple (MWP) is the most important disease of pineapple worldwide. During the months of September and November 2020, pineapple production fields of the cultivar Hawaiiana and hybrid MD-2 in Satipo and Chanchamayo provinces of Peru, showed typical symptoms of MWP. Based on symptoms, the disease incidence level ranged between 70 and 90%. Symptomatic and asymptomatic foliar samples were collected and tested by...
Insights into gene expression responses to infections in teleosts using microarray data: a systematic reviewNARA Subscribed
The rapid growth of production in aquaculture in the last decades has brought unwanted consequences affecting fish health and increasing the susceptibility to different infections. This systematic review aimed to analyse and summarize the current knowledge of gene expression responses to infectious diseases in teleosts using viruses, bacteria, fungi and parasites as agents through published microarray data. We conducted search...
Embryonic development and larval morphology of Chromis crusma was described from five nests sampled between 21 and 25 m depth in central Chile (33°S). From each nest, a set of c . 100 randomly selected eggs were hand‐collected and transported in seawater to the laboratory. Subsets of c . 30 eggs per nest were maintained in 50 ml glass containers at a constant ambient temperature of c . 12°C (range 11.5–12.9°C). Egg length ( L...
