Farm Productions and Rural Landscapes

2017

Farm landscapes in the Philippines are dominated by rice and coconuts in most provinces. In a country of generally small farm holdings, rice, the staple food, is cultivated across the archipelago, even if corn plays a bigger role in the southern part of the country. In the mountains of northern Luzon, the Ifugao tribe have developed over several centuries a remarkable landscape of rice terraces on steep slopes, but most of the rice is grown in the plains of Central Luzon around Manila. The coconut “tree of life”, most abundant in Quezon and Bicol, is used in many different ways, from food to construction materials. Bananas and pineapple are the leading export productions, mostly grown on la…

The response of an egg parasitoid to substrate-borne semiochemicals is affected by previous experience

2016

AbstractAnimals can adjust their behaviour according to previous experience gained during foraging. In parasitoids, experience plays a key role in host location, a hierarchical process in which air-borne and substrate-borne semiochemicals are used to find hosts. In nature, chemical traces deposited by herbivore hosts when walking on the plant are adsorbed by leaf surfaces and perceived as substrate-borne semiochemicals by parasitoids. Chemical traces left on cabbage leaves by adults of the harlequin bug (Murgantia histrionica) induce an innate arrestment response in the egg parasitoid Trissolcus brochymenae characterized by an intense searching behaviour on host-contaminated areas. Here we …

First record of the pencil cardinal Epigonus denticulatus (Perciformes: Epigonidae) in the Azores archipelago

2021

The pencil cardinal Epigonus denticulatus is a small deep-water fish inhabiting continental slopes usually between 300 m and 600 m depth. We report the first record of E. denticulatus in the Azores archipelago, where one specimen was found floating by fisherman off Faial island. Meristic and morphometric characters are in accordance with those reported for the species and molecular analyses further supported species identity. The record of E. denticulatus as a native species in the Azores, increases the number of Epigonus species in the region for a total of three. This article is protected by copyright.

&lt;p&gt;&lt;strong&gt;A new species of the genus &lt;em&gt;Glischrochilus&lt;/em&gt; Reitter (Coleoptera: Nitidulidae: Cryptarchinae) from China&lt;…

2016

The cosmopolitan genus Glischrochilus Reitter, 1873 (Nitidulidae: Cryptarchinae) is distributed in Holarctic and Oriental regions. According to the most recent catalogue (Jelinek & Audisio 2007), 32 species are known from the Palaearctic region. In China the genus is represented by 13 species, most of which were described by Jelinek (1975, 1982, 1999) and Lason (2009).

Fishery-dependent and -independent data lead to consistent estimations of essential habitats

2016

AbstractSpecies mapping is an essential tool for conservation programmes as it provides clear pictures of the distribution of marine resources. However, in fishery ecology, the amount of objective scientific information is limited and data may not always be directly comparable. Information about the distribution of marine species can be derived from two main sources: fishery-independent data (scientific surveys at sea) and fishery-dependent data (collection and sampling by observers in commercial vessels). The aim of this paper is to compare whether these two different sources produce similar, complementary, or different results. We compare them in the specific context of identifying the Es…

Modelling sensitive elasmobranchs habitat

2013

Basic information on the distribution and habitat preferences of ecologically important species is essential for their management and protection. In the Mediterranean Sea there is increasing concern over elasmobranch species because their biological (ecological) characteristics make them highly vulnerable to fishing pressure. Their removal could affect the structure and function of marine ecosystems, inducing changes in trophic interactions at the community level due to the selective elimination of predators or prey species, competitors and species replacement. In this study Bayesian hierarchical spatial models are used to map the sensitive habitats of the three most caught elasmobranch spe…

Only Females Oviposit: Chemical Discrimination of Adult Stink Bug Sex by the Egg Parasitoid Trissolcus japonicus

2021

Egg parasitoids foraging for suitable hosts scattered in the environment rely mainly on chemical cues. Elucidating the chemical ecology of natural enemies is important in the development of effective and successful strategies for conservation biological control. In this context, the host cuticular hydrocarbons, which are exploited by several species of egg parasitoids as contact kairomones, could be used to retain them by providing information about the presence and the sex of adults of the target species: sex is important because only females of the host species lay the eggs that can be subsequently utilized for parasitoid reproduction. However, the chemical basis of host sex discriminatio…

Two-Dimensional Numerical Modelling of a Moored Floating Body under Sloping Seabed Conditions

2020

A coupled floating body-mooring line model is developed by combining a boundary element model for a two-dimensional floating body and a catenary mooring line model. The boundary element model is formulated in the time domain by a continuous Rankine source, and a reflection potential is introduced to account for the wave reflection due to sloping seabed. This newly developed model is validated by comparisons against available data. Then, dynamic response analyses are performed for the moored body in various seabed conditions. Compared with a flat seabed, a sloping seabed causes unsymmetrical mooring line configuration and generates noticeable effects in the motion responses of the floating b…

Efficient Parallel Sort on AVX-512-Based Multi-Core and Many-Core Architectures

2019

Sorting kernels are a fundamental part of numerous applications. The performance of sorting implementations is usually limited by a variety of factors such as computing power, memory bandwidth, and branch mispredictions. In this paper we propose an efficient hybrid sorting method which takes advantage of wide vector registers and the high bandwidth memory of modern AVX-512-based multi-core and many-core processors. Our approach employs a combination of vectorized bitonic sorting and load-balanced multi-threaded merging. Thread-level and data-level parallelism are used to exploit both compute power and memory bandwidth. Our single-threaded implementation is ~30x faster than qsort in the C st…
