Hatching failure and embryo mortality in endangered populations of Eurasian Curlew (Numenius arquata)

Ibis, EarlyView.
Hatching failure represents a significant and growing barrier to reproductive success in threatened birds and yet is often poorly understood. Populations of the Eurasian Curlew Numenius arquata in the United Kingdom and Republic of Ireland have experienced significant declines over recent decades, and low breeding productivity is a major barrier to ...

On the origin of brood parasitism in altricial birds

The probability that obligate interspecific brood parasitism (OP), among altricial birds evolved directly from the normal breeding (no parasitism, NP) mode or indirectly through intraspecific nest parasitism (INP) was examined by using maximum-likelihood

Fragmented grasslands in different landscape structures provide different opportunities for cavity‐nesting Hymenoptera

Insect Conservation and Diversity, EarlyView.
Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers

Nesting habits, alternative nesting strategies and female territoriality of the cockroach-hunting solitary wasp Penepodium luteipenne (Hymenoptera: Sphecidae)

Journal of Hymenoptera Research, 2012
The nesting behaviour of the cockroach-hunting solitary wasp Penepodium luteipenne (Fabricius, 1804) is described, including five different nesting tactics: digging of new nests, use of pre-existing burrows in the soil, brood parasitism of open nests ...

Food resources are more important than nesting resources for explaining wild bee diversity in urban gardens Nahrungsressourcen haben einen größeren Einfluss auf die Wildbienendiversität in urbanen Gärten als das Nistangebot

Insect Conservation and Diversity, EarlyView.
Urban community gardens showed a high wild bee diversity with 168 recorded species, representing roughly 30% of Germany's wild bees, including threatened species like Osmia mitis and Coelioxys lanceolata. Floral resources, not nesting resources or habitat availability, were the main drivers for wild bee taxonomic and functional diversity.

The evolution of egg rejection by cuckoo hosts in Australia and Europe [PDF]

, 2005
Exploitation of hosts by brood parasitic cuckoos is expected to stimulate a coevolutionary arms race of adaptations and counteradaptations. However, some hosts have not evolved defenses against parasitism.

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Adaptation to extreme environments: A review of Antarctic fish physiology

Journal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane

Seasonal increase in nest defense, but not egg rejection, in a cuckoo host

Avian Research
The interactions between avian brood parasites and their hosts provide an informative and easy-to-handle system for studying coevolution. Avian brood parasitism reduces the reproductive success of hosts, and thus, hosts have evolved anti-parasitic ...
