The family Monophlebidae is distributed worldwide and is classified as one of the "archaeococcoid" families. After almost 160 years since Germar & Berendt (1856) described the first and so far only fossil monophlebid species, Monophlebus irregularis, two new fossil species of a new and undoubtedly monophlebid genus Palaeophlebus gen. n. are described from Baltic amber. Morphological features of the new genus and its two species, P. hoffeinorum sp. n. and P. kotejai sp. n., are discussed.

This paper presents a revision of the aphid genus Oviparosiphum, which is known from the Cretaceous period. Redescriptions of two species: Oviparosiphumjakovlevi Shaposhnikov, 1979 and Oviparosiphumbaissense Shaposhnikov & Wegierek, 1989 are made, and an updated diagnosis of this genus is provided. Oviparosiphumbaissense is the type species of a newly described genus Archeoviparosiphum gen. n. Five other species of Oviparosiphum are also transferred to the new genus. The basis for their separation from Oviparosiphum is the structure of the siphunculi and ovipositor. A key is provided to the genera of Oviparosiphidae.

First specific records of chironomids of the tribe Tanytarsini from New Caledonia based on detailed descriptions of new species are presented. Cladotanytarsus (Cladotanytarsus) stylifer sp. Nov. and its closest relatives, i.a. Cladotanytarsus (C.) isigacedeus (Sasa et Suzuki, 2000), comb. Nov., known from males bearing extraordinarily elongate hypopygial anal points are diagnosed. Paratanytarsus mirificus sp. Nov. is described as adult male with unique structure of its hypopygium and shortened antennae. Diagnostic description of Tanytarsus fuscithorax Skuse, 1889 is also complemented. Copyright © 2015 Magnolia Press.

Retracing complex population processes that precede extreme bottlenecks may be impossible using data from living individuals. The wisent (Bison bonasus), Europes largest terrestrial mammal, exemplifies such a population history, having gone extinct in the wild but subsequently restored by captive breeding efforts. Using low coverage genomic data from modern and historical individuals, we investigate population processes occurring before and after this extinction. Analysis of aligned genomes supports the division of wisent into two previously recognized subspecies, but almost half of the genomic alignment contradicts this population history as a result of incomplete lineage sorting and admixture. Admixture between subspecies populations occurred prior to extinction and subsequently during the captive breeding program. Admixture with the Bos cattle lineage is also widespread but results from ancient events rather than recent hybridization with domestics. Our study demonstrates the huge potential of historical genomes for both studying evolutionary histories and for guiding conservation strategies.

The Whiskered Tern population in Poland has rapidly increased from 40 breeding pairs in 1990 to over 1,600 in 2007, with strongest local population in the Upper Vistula River Valley. Owing to rather low pre-breeding and adult apparent survival rates estimated for this population (0.54 and 0.80, respectively) and a delay in accession to reproduction (recruitment completed at age 3), matrix modelling indicated an intrinsic growth rate of λcalc = 1.02. Observed growth rates of both the Polish and the Upper Vistula River Valley populations was λobs = 1.29. Using the deterministic population projection matrix including immigrant class, we estimated that, on average, 44 immigrants should enter the Upper Vistula River Valley population annually to match the observed growth. With survival rates increased (ΦP = 0.63, ΦB = 0.90) as to mimic no emigration and reduced dispersal, the estimated number of immigrants was only eight, indicating that substantial emigration rates are likely. A majority of the breeding sites were recorded in man-made water bodies. Colonisation has started in the southeast and proceeded towards the northwest. The strong, stable population in western Ukraine may explain high numbers of immigrants that could originate from there. Other factors favouring quick colonisation of Poland include availability of suitable breeding sites, the wide flexibility of the species with respect to breeding habitat, plentiful food, and high breeding success in the Upper Vistula River Valley. It also seems likely that westward shifts in both breeding and wintering ranges could add to the strong population increases in Eastern Europe. © 2013 The Author(s).

A method for trapping both parents of Whiskered Terns (Chlidonias hybrida), a semi-precocial species, using enclosures that allow access to the chicks until they fledge is described. The approach combines the gradual installation of enclosures with their subsequent, temporary conversion into traps used to capture adult birds. The success rate for trapping both mates on the target nests (n = 83) was 77%. Nest desertions after the erection of the enclosure and after trapping were 1% and 3%, respectively. A high effectiveness of trapping both parents and a low percentage of losses can be achieved with the gradual installation of the enclosure and the birds' habituation to it. This trapping technique is safe and efficient, enabling researchers to collect samples from all family members with ease. © 2015, The Waterbird Society. All rights reserved.

Capsule In the Whiskered Tern Chlidonias hybrida, hatching success was similar at nests where both parents were caught during the same trapping session and nests where parents were caught on different days. Trapping both mates during the same session may represent an efficient approach to reduce fieldwork effort, but it should be preceded by a pilot study, confirming that it does not affect breeding success. © 2016 British Trust for Ornithology

We present the first-ever survival estimates of the Whiskered Tern Chlidonias hybrida, based on the analysis of capture-recapture data (403 adults and 1,484 chicks ringed) collected between 1993 and 2011 in an increasing breeding population in southern Poland. Data were modelled using multistate models with an unobservable state, accounting for the period during which young terns remain at their winter quarters. Model-averaged pre-breeding and breeding survival were estimated to be 0.54 [standard error (SE) 0.28] and 0.80 (SE = 0.05), respectively. All models were in agreement that the relative proportion of breeders was nearly zero in the second calendar year, increasing to reach values close to 0.8 in the fifth calendar year, which confirms the observation of a much delayed maturation of the Whiskered Tern. Our data indicate that most Whiskered Tern start to breed about 1 year earlier than members of genera Sterna and Onychoprion. However, the precision of the estimates for the parameter describing the transition probability from the unobservable pre-breeding to the observable breeding state was extremely poor; therefore, these estimates should be treated as tentative until more data are collected. The three best-supported models indicated significant annual variation in recapture probability. The results also suggested that forced exchange of breeding colonies is frequent in the study area; consequently, a large proportion of birds ringed as chicks are breeding in colonies other than their respective natal colony. This exchange is best explained not by the trapping and ringing activity but by human management of the environment, such as water level changes in dam reservoirs and carp Cyprinus carpio farming at fish ponds, both of which result in breeding habitats becoming unstable and periodically unavailable, possibly forcing birds to change breeding sites. © 2013 The Author(s).
