Grotta Dell'Artiglieria
Grotta dell'Artiglieria ("Artillery Cave") is a Karst cave in the municipality of Doberdò del Lago (Gorizia, Friuli Venezia Giulia, Italy). The cave is located NE of Doberdob Lake, near the top of a small hill, in the small village of ''Jamiano''. The name is referred to the artillery battery set in the cave during World War I. Morphology Grotta dell'Artiglieria opens above sea level. Overall, it is long and deep. The cave is made up of three main rooms, connected by small pits. The entrance is vertical and leads to the first room. On the left side of this cavern, a pit leads to the second room. Another small pit, made up of collapsed bedrocks, leads to the last room, which is the biggest one. This room is full of cave formations and declines subhorizontally until reaching the deepest part of the cave. History The cave entrance is located in the vicinity of a panoramic viewpoint, whence it is possible to observe most of the Gorizia Karst, including Doberdob Lake. B ...

Doberdò Del Lago
Doberdò del Lago ( sl, Doberdob; Bisiacco: ; fur, Dobardò) is a ''comune'' (municipality) in the Italian region Friuli-Venezia Giulia, located about northwest of Trieste and about southwest of Gorizia, and borders the following municipalities: Duino-Aurisina, Fogliano Redipuglia, Komen (Slovenia), Miren-Kostanjevica (Slovenia), Monfalcone, Ronchi dei Legionari, Sagrado, and Savogna d'Isonzo. It is located in the westernmost part of the Karst Plateau. It is inhabited mostly by Slovenes. Before World War I, Slovene-speakers comprised almost the totality (around 99%) of the population. In the 1971 census, 96% of the inhabitants were Slovene-speaking. Since then, the number of Slovenes has slightly fallen, mostly due to the increased immigration of Italian speakers from neighboring towns of Monfalcone and Ronchi dei Legionari. Today, an estimated 86% of the inhabitants belong to the Slovene ethnic minority. Doberdò localities include Devetachi/Devetaki, Jamiano/Jamlje, ...

Observation Post
An observation post (commonly abbreviated OP), temporary or fixed, is a position from which soldiers can watch enemy movements, to warn of approaching soldiers (such as in trench warfare), or to direct fire. In strict military terminology, an observation post is ''any'' preselected position from which observations are to be made - this may include very temporary installations such as a vehicle parked as a roadside checkpoint, or even an airborne aircraft. (from a DoD news briefing. Accessed 2008-06-21.) Operation When selecting a (temporary) observation post, trained troops are to avoid ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra ...

Food Source
Food is any substance consumed by an organism for nutritional support. Food is usually of plant, animal, or fungal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells to provide energy, maintain life, or stimulate growth. Different species of animals have different feeding behaviours that satisfy the needs of their unique metabolisms, often evolved to fill a specific ecological niche within specific geographical contexts. Omnivorous humans are highly adaptable and have adapted to obtain food in many different ecosystems. The majority of the food energy required is supplied by the industrial food industry, which produces food with intensive agriculture and distributes it through complex food processing and food distribution systems. This system of conventional agriculture relies heavily on fossil fuels, which means that the food and agricultur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Community (ecology)
In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage. The term community has a variety of uses. In its simplest form it refers to groups of organisms in a specific place or time, for example, "the fish community of Lake Ontario before industrialization". Community ecology or synecology is the study of the interactions between species in communities on many spatial and temporal scales, including the distribution, structure, abundance, demography, and interactions between coexisting populations. The primary focus of community ecology is on the interactions between populations as determined by specific genotypic and phenotypic characteristics. Community ecology also takes into account abiotic factors that influence species distributions or interactions (e.g. annual tempe ...

Bat Guano
Guano (Spanish from qu, wanu) is the accumulated excrement of seabirds or bats. As a manure, guano is a highly effective fertilizer due to the high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth. Guano was also, to a lesser extent, sought for the production of gunpowder and other explosive materials. The 19th-century seabird guano trade played a pivotal role in the development of modern input-intensive farming. The demand for guano spurred the human colonization of remote bird islands in many parts of the world. Unsustainable seabird guano mining processes can result in permanent habitat destruction and the loss of millions of seabirds. Bat guano is found in caves throughout the world. Many cave ecosystems are wholly dependent on bats to provide nutrients via their guano which supports bacteria, Fungus, fungi, Invertebrate, invertebrates, and Vertebrate, vertebrates. The loss of bats from a cave can result in the extinction of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hibernation
Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months. Although traditionally reserved for "deep" hibernators such as rodents, the term has been redefined to include animals such as bears and is now applied based on active metabolic suppression rather than any absolute decline in body temperature. Many experts believe that the processes of daily torpor and hibernation form a continuum and utilise similar mechanisms. The equivalent during the summer months is aestivation. Hibernation functions to conserve energy when sufficient food is not available. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. Hibernation may last days, weeks, or months—depending on the species, ambient temperatu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breeding Season
Seasonal breeders are animal species that successfully mate only during certain times of the year. These times of year allow for the optimization of survival of young due to factors such as ambient temperature, food and water availability, and changes in the predation behaviors of other species. Related sexual interest and behaviors are expressed and accepted only during this period. Female seasonal breeders will have one or more estrus cycles only when she is "in season" or fertile and receptive to mating. At other times of the year, they will be anestrus, or have a dearth of their sexual cycle. Unlike reproductive cyclicity, seasonality is described in both males and females. Male seasonal breeders may exhibit changes in testosterone levels, testes weight, and fertility depending on the time of year. Seasonal breeders are distinct from opportunistic breeders, that mate whenever the conditions of their environment become favorable, and continuous breeders that mate year-ro ...

Common Bent-wing Bat
The common bent-wing bat (''Miniopterus schreibersii''), also known as the Schreibers's long-fingered bat or Schreibers's bat, is a species of insectivorous bat. They appear to have dispersed from a subtropical origin and distributed throughout the southern Palearctic, Ethiopic, Oriental, and Australian regions. In Europe, it is present in the southern half on the continent from Iberia to the Caucasus, with the largest populations found in the warmer Mediterranean area. The common and scientific names honor Carl Franz Anton Ritter von Schreibers. Taxonomy There are 13 recognised subspecies of the common bent-winged bat. * ''Miniopterus schreibersii schreibersii'' * ''Miniopterus schreibersii bassanii'' (southern bent-wing bat): Found in southeastern Australia, this subspecies is critically endangered.Department of the Environment (2017).

Colony (biology)
In biology, a colony is composed of two or more conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. Colonies can form in various shapes and ways depending on the organism involved. For instance, the bacterial colony is a cluster of identical cells (clones). These colonies often form and grow on the surface of (or within) a solid medium, usually derived from a single parent cell. Colonies, in the context of development, may be composed of two or more unitary (or solitary) organisms or be modular organisms. Unitary organisms have determinate development (set life stages) from zygote to adult form and individuals or groups of individuals (colonies) are visually distinct. Modular organisms have indeterminate growth forms (life stages not set) through repeated iteration of genetically identical modules (or individuals), and it can be diffi ...
