Insights on cytotoxic cells of the colonial ascidian Botryllus schlosseri [PDF]
, 2015 Morula cells (MCs) represent the most abundant circulating hemocyte of the compound ascidian Botryllus schlosseri. They are cytotoxic cells involved in the rejection reaction between contacting, genetically incompatible colonies.

Climate Change and invasibility of the Antarctic benthos [PDF]
, 2007 Benthic communities living in shallow-shelf habitats in Antarctica (<100-m depth) are archaic in their structure and function. Modern predators, including fast-moving, durophagous (skeleton-crushing) bony fish, sharks, and crabs, are rare or absent ...

Comparing and contrasting development and reproductive strategies in the pupal hyperparasitoids Lysibia nana and Gelis agilis (Hymenoptera: Ichneumonidae) [PDF]
, 2007 In most animals, the optimal phenotype is determined by trade-offs in life-history traits. Here, I compare development and reproductive strategies in two species of solitary secondary hyperparasitoids, Lysibia nana and Gelis agilis, attacking pre-pupae ...

Insects and Survival: A Review of Primary and Secondary Defense Strategies
Entomologia Experimentalis et Applicata, EarlyView.Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

RNAi efficiency, systemic properties, and novel delivery methods for pest insect control : what we know so far [PDF]
, 2016 In recent years, the research on the potential of using RNA interference (RNAi) to suppress crop pests has made an outstanding growth. However, given the variability of RNAi efficiency that is observed in many insects, the development of novel approaches

Offspring Dependency Is Not Reflected in the Social Immunity of Three Burying Beetle Species
Entomologia Experimentalis et Applicata, EarlyView.Nicrophorus pustulatus, Nicrophorus vespilloides, and Nicrophorus orbicollis are three burying beetle species that differ both in their ecology and in the dependency of their offspring on parental care. This gradient of offspring dependency might be reflected in the parents' social immunity capabilities and/or investment.
