Next-generation biological control

2020

Biological control is widely successful at controlling pests, but effective biocontrol agents are now more difficult to import from countries of origin due to more restrictive international trade laws (the Nagoya Protocol). Coupled with increasing demand, the efficacy of existing and new biocontrol agents needs to be improved with genetic and genomic approaches. Although they have been underutilised in the past, application of genetic and genomic techniques is becoming more feasible from both technological and economic perspectives. We review current methods and provide a framework for using them. First, it is necessary to identify which biocontrol trait to select and in what direction. Nex…

Genome sequence of the pea aphid Acyrthosiphon pisum

2010

The genome of the pea aphid shows remarkable levels of gene duplication and equally remarkable gene absences that shed light on aspects of aphid biology, most especially its symbiosis with Buchnera.

New national and regional bryophyte records, 67

2021

Bulgaria. Samokov Region, Rila Mountains, Rila National Park, N slopes of peak Deno, on granite slabs and scree, collected with occasional sporophytes, 42.19709°N, 23.60322°E, 2780 m a.s.l, 17 September 2019, leg./det. R. Natcheva s.n. (SOM 9811-B). This arctic-alpine species has a north Holarctic circumpolar distribution and this is the first report of Andreaea blyttii for SE Europe. It is its southernmost locality and extends its range further south in Europe. The Rila Mountains are the highest in the Balkan peninsula and A. blyttii was found near the highest summit (Mussala, 2925 m a.s.l.). In Bulgaria the genus Andreaea is also represented by A. alpestris (Thed.) Schimp. and A. rupestri…

Molecular characterization of <em>Vitis vinifera</em> L. local cultivars from volcanic areas (Canary Islands and Madeira) using SSR marke…

2019

Aim: This study characterises and identifies 79 grapevine accessions from the Canary Islands and 14 from Madeira using simple sequence repeat (SSR) analysis.Methods and Results: A kit of 20 microsatellites or simple sequence repeats (SSRs) were used to obtain the molecular profiles of the 93 accessions in this study. The results allowed us to identify four new cultivars (Bienmesabe tinto, Burra volcanica, Vallera, Verijadiego negro), two new colour mutations (Listan rosa, Mollar cano rosado) and two unknown molecular profiles from Madeira. Furthermore, we propose that eight names of varieties be included in the Vitis International Variety Catalogue (VIVC) as prime names, and 38 accession na…

Priorities for research in soil ecology

2017

The ecological interactions that occur in and with soil are of consequence in many ecosystems on the planet. These interactions provide numerous essential ecosystem services, and the sustainable management of soils has attracted increasing scientific and public attention. Although soil ecology emerged as an independent field of research many decades ago, and we have gained important insights into the functioning of soils, there still are fundamental aspects that need to be better understood to ensure that the ecosystem services that soils provide are not lost and that soils can be used in a sustainable way. In this perspectives paper, we highlight some of the major knowledge gaps that shoul…

Human-Bat Interactions in Rural Southwestern Madagascar through a Biocultural Lens

2021

Human-bat interactions are common in rural areas across the tropics. Over 40 bat species occur in Madagascar, most of which are endemic. Forest loss is changing the distribution of bats throughout the island, with potential increases in both the abundance of synanthropic species and human-bat interactions. We set out to study knowledge of, interactions with, and attitudes towards bats in rural Madagascar, including reports of food and ethnomedicinal uses of bats, their cultural representations in folklore, and the existence of culturally enforced taboos in relation to them. We administered 108 surveys with open- and closed-ended questions with adults from the Tanala and Betsileo ethnic grou…

Plant communities of the Czerwona Woda River Valley (Stołowe Mountains National Park)

2018

Abstract The Czerwona Woda River is the main watercourse in the Stołowe Mountains National Park and drains the major part of the Stołowe Mts. It was regulated in the past, but its channel has been spontaneously naturalised. Now, managed spruce forests grow along almost the entire length of this small mountain stream. The aims of the present study were to investigate diversity of plant communities connected with the Czerwona Woda stream and to prepare detailed vegetation maps. The results obtained can potentially be a reference for future restoration projects implemented in the Stołowe Mountains National Park. As a result of vegetation mapping, there were distinguished 20 plant communities r…

Variation in timing of breeding of five woodpeckers in a primeval forest over 45 years: role of food, weather, and climate

2020

AbstractClimate warming could lead to ‘mis-matching’ of birds’ breeding times with availability of their invertebrate food resources. Fluctuating spring temperatures could influence variation in the commencement of egg-laying, as well as, in phenology of their resources (e.g., tree bud burst, appearance of folivorous caterpillars). We studied timing of Dendrocopos leucotos, Dendrocoptes medius, Dendrocopos major, Dryobates minor, and Picoides tridactylus breeding in, free of direct human intervention, strictly protected fragments of Białowieża Forest (Poland) in 1975–2019. We related their onset of breeding to inter-year variation in spring weather, trees’ bud burst and timing of folivorous…
