Abstract:

We sowed seeds of Pinussylvestris L., Pinuscontorta Dougl, Piceaabies (L.) Karst., and Piceamariana (Mill.) B.S.P. at five different virgin peatland sites in northern Sweden. Seeds were sown in 1987, 1988, 1989, and 1990. The seeds were sown in three different types of microhabitat, viz Pleurozium, Sphagnumfuscum, and Sphagnumangustifolium. Germination and seedling mortality were monitored each year. Both germination and mortality were significantly affected by the micro-habitat. Sphagnumangustifolium microhabitats were most favourable and Pleurozium microhabitats were least favourable for ger

The microhabitat preference of caddisfly (Trichoptera) communities was studied in 8 types of microhabitats in a fast-flowing, medium-sized, lowland stream in Latvia. A total 36 caddisfly taxa belonging to 14 families were recorded in microhabitat samples. A PCA biplot of caddisfly taxa abundance in microhabitats showed 3 distinct caddisfly taxa groups: depositional [Limnephilidae Gen. sp., Anabolia laevis (Zetterstedt) and Lasiocephala basalis (Kolenati)], lithal [Agapetus ochripes Curtis and Psychomyia pusilla (Fabricius)], and submerged macrophyte and water moss caddisfly microhabitat commun

Abstract. Cold-water coral (CWC) reefs are heterogeneous ecosystems comprising numerous microhabitats. A typical European CWC reef provides various biogenic microhabitats (within, on and surrounding colonies of coral species such as Lophelia pertusa, Paragorgia arborea and Primnoa resedaeformis, or formed by their remains after death). These microhabitats may be surrounded and intermixed with non-biogenic microhabitats (soft sediment, hard ground, gravel/pebbles, steep walls). To date, studies of distribution of sessile fauna across CWC reefs have been more numerous than those investigating mo

We examined variation in microhabitat use and availability among four distinct forest types.

Moreover, adult populations may be influenced by recruitment of juveniles and assessments of habitat importance should consider relative effects of juvenile abundance.

As forest management intensifies, the conservation of forest biodiversity is a growing concern. Bryophytes are known to represent a considerable portion of plant diversity within northern forests. This is because bryophyte diversity is closely associated with microhabitat diversity.

The results indicate that bryophyte diversity (species richness, abundance, and evenness) is quite variable among microhabitats. The accumulation of species richness wit

We created different types of microhabitats by adding different forms of nitrogen (NH4+, NO3− and glycine) or combinations of these nitrogen in an even or patchy way.

Abstract Although amphibians undergo drastic changes in physiology and behaviour before hibernation, this phase of their life cycle (i.e., brumation) is the least understood. We investigated the patterns of microhabitat use by Dryophytes japonicus during brumation using a Harmonic Direction Finder to track 27 adults in October 2013. Most frogs used chestnut trees throughout their diel cycle. The species was most active within the “leafy vegetation” microhabitat, moving about 2 m within 72 h on average, and mostly circa 10 AM. Frogs moved less in the four other microhabitats, with individuals m

Abstract:The process by which solitary animals evolve to live in groups is a central question in biology. Conspecifics that compete for patchy resources may evolve incipient social behaviours such as group formation and conspecific tolerance when persistent aggressive interactions reduce resource access. In this investigation, a facultative group living species of whip spider was studied to understand the microhabitat resources that support group formation. Although most species of whip spider are solitary and oftentimes cannibalistic, Heterophrynus batesii sometimes aggregate in small groups

Abstract:

Abstract Convergent evolution, the evolution of similar phenotypes among distantly related lineages, is often attributed to adaptation in response to similar selective pressures. Here, we assess the prevalence and degree of convergence in functional traits of stream fishes at the microhabitat scale in five zoogeographical regions across the world. We categorized species by microhabitat, water velocity and preference for substrate complexity and calculated the prevalence of convergence, degree of convergence and functional diversity for each category. Among species occupying similar microhabita

Abstract:

During 1997-1998, we investigated the influence of both the relative abundance of truffles, preferred food items, and microhabitat structure on the occurrence of northern flying squirrels (Glaucomys sabrinus Shaw) in old-growth forest habitat of the Sierra Nevada Range, U.S.A. Following live-trapping sessions, we searched the forest floor for truffle diggings and sampled the soil for truffles. Diggings were more abundant where flying squirrels were captured, suggesting squirrels were active near areas of the forest floor where truffles had recently been excavated.

The forests in the Häme region are characterized by a long history of forest utilization, while the forests in the KuhmoViena region can be regarded as natural or near natural.

Abstract:

Identifying the historical processes that drive microhabitat transitions across deep time is of great interest to evolutionary biologists. Morphological variation can often reveal such mechanisms, but in clades with high microhabitat diversity and no concomitant morphological specialization, the factors influencing animal transitions across microhabitats are more difficult to identify. Lungless salamanders (family: Plethodontidae) have transitioned into and out of the arboreal microhabitat many times throughout their evolutionary history without substantial morphological specialization.

Until recently, marine scientists have relied heavily on satellite sea surface temperatures and terrestrial weather stations as indicators of the way in which the thermal environment, and hence the body temperatures of organisms, vary over spatial and temporal scales. We designed biomimetic temperature loggers for three species of rocky intertidal invertebrates to determine whether mimic body temperatures differ from the external environment and among species and microhabitats. For all three species, microhabitat temperatures were considerably higher than the body temperatures, with difference

Reducing water depth increased the number of parasites per infected fish in G. aculeatus and increased the percentage of G. wheatlandi infected. For both species, intensity of infection and percentage of fish infected were greater am
