Regulation of building behaviour relating to nest space and transport in leaf-cutting ants

, 2016
Ants build structures that facilitate the life of the colony. The structures are created in a highly variable environment by workers that lack centralised communication or a fixed plan.

Candicidin-producing Streptomyces support leaf-cutting ants to protect their fungus garden against the pathogenic fungus Escovopsis

, 2009
Leaf-cutting ants such as Acromyrmex octospinosus live in obligate symbiosis with fungi of the genus Leucoagaricus, which they grow with harvested leaf material. The symbiotic fungi, in turn, serve as a major food source for the ants.

Identification of a Susceptibility Gene for Xanthomonas oryzae pv. oryzae in Vietnamese Elite Rice (Oryza sativa L.) Cultivar Bacthom 7

Plant Breeding, EarlyView.
ABSTRACT Xanthomonas oryzae pv. oryzae (Xoo) is the causal agent of bacterial leaf blight (BLB) disease in rice, exerting a detrimental impact on the yield of various rice cultivars in Vietnam, notably the Bacthom 7 (BT7) variety. Xoo possesses transcription activator‐like effectors (TALEs) which modulate the expression of host genes by specifically ...

Comparative analysis of immune responses in ovipositing and non‐ovipositing females of European earwig Analyse comparative de la réponse immunitaire avant et après la ponte chez le forficule européen

Physiological Entomology, EarlyView.
Oviposition and care decrease the total haemocyte concentration. Oviposition and care affect haemocyte type proportions. Serratia marcescens challenge does not affect the immune cell parameters. Abstract Reproduction and immunity are essential biological processes that compete for resources and energy.

Genetic caste polymorphism and the evolution of polyandry in Atta leaf-cutting ants

, 2011
Multiple mating by females with different males (polyandry) is difficult to explain in many taxa because it carries significant costs to females, yet benefits are often hard to identify.

AI Alignment Versus AI Ethical Treatment: 10 Challenges

Analytic Philosophy, EarlyView.
ABSTRACT A morally acceptable course of AI development should avoid two dangers: creating unaligned AI systems that pose a threat to humanity and mistreating AI systems that merit moral consideration in their own right. This paper argues these two dangers interact and that if we create AI systems that merit moral consideration, simultaneously avoiding ...

Attraction of nocturnal scarab beetles by unusual floral volatiles in a Banksia (Proteaceae) with functionally diverse pollinators

Plant Biology, EarlyView.
Banksia attenuata (Proteaceae) attracts nocturnal scarab beetles with an unusual floral scent—the beetles pollinate the flower as they feed on pollen and nectar and mate on the inflorescences. Abstract Pollination by beetles has evolved multiple times in flowering plants but with relatively few plant species adapted specifically to pollination by ...
