1. 2D or not 2D? Three-dimensional home range analysis better represents space use by an arboreal mammal

Abstract:
... For animals which utilise vertically distributed habitat resources, home ranges quantified in two-dimensions (2D) likely misrepresent space use and constrain interpretations of species' ecology and behaviour. Three-dimensional (3D) home range estimation has proved useful for understanding space use over relatively large vertical ranges (e.g. 100's of meters), yet none have applied a 3D approach to ...

Abstract:
... The taxonomic status of two species of the spookfish genus Harriotta Goode and Bean 1895 is revised and discussed. On the basis of a literature review along with a comparison between the two species formerly considered valid, H. haeckeli Karrer 1972 is synonymized with H. raleighana Goode and Bean 1895, and Anteliochimaera chaetirhampha Tanaka 1909 previously regarded as a junior synonym of the la ...

Abstract:
... Estimating the realized and potential distribution of species has become a very active field of research with capacity to propose likely speciation mechanisms. Here, environmental variables and point locality data derived from several sources were used to examine the concordance between geographical distributions and environmental niches derived from occurrences for eleven species of the genus Uro ...

Abstract:
... Spatial environmental heterogeneity coupled with dispersal can promote ecological persistence of diverse metacommunities. Does this premise hold when metacommunities evolve? Using a two‐resource competition model, we studied the evolution of resource‐uptake specialisation as a function of resource type (substitutable to essential) and shape of the trade‐off between resource uptake affinities (gene ...

Abstract:
... Mating preferences vary among individuals in response to a number of factors, such as the age and phenotype of the choosing individual. However, studies addressing variation in mating preferences generally focus on female preferences and usually are limited to choice within a species. Variation in preferences likely also exists at the species boundary, affecting an individual’s propensity to mate ...

Abstract:
... Territoriality is a widespread behavioral phenomenon that functions for partitioning space and defending resources. Birds tend to defend territories against homospecific individuals through long-distance acoustic signals, but some species also exhibit interspecific territoriality. Two main hypotheses could explain interspecific territoriality mediated by long-distance acoustic signals: (1) misiden ...

We report on two lady beetle species, Oenopia conglobata (Linnaeus) and Adalia bipunctata (Linnaeus), sympatric in Chaharmahal and Bakhtiari Province, Iran, closely resembling each other in coloration. This may be an interesting example of Müllerian mimicry. The putative model, O. conglobata, retains its typical pink elytral background with 16 black spots, whereas the locally most common form (for ...

Abstract:
... Whether phenotypic evolution is always adaptive is a major issue in evolutionary biology. Based on the great morphological variation and slight ecological variation, Willis argued that Podostemaceae evolved in the absence of adaptation. Podostemaceae are ecological specialists with roots or holdfasts adhering to macrophyte-free (in Asia), soilless rock surfaces submerged in fast-flowing river curr ...

Abstract:
... Several artisanal fisheries target deepwater species. These stocks are highly sensitive to overfishing because of their slow growth and late maturation. This vulnerability is higher if species concentrate during spawning season in coastal areas, as occur with scabbardfish (Aphanopus spp.). In this paper, we explore if two Aphanopus species (A. carbo and A. intermedius) that coexist show migration ...

We report the capture of individuals of two species of phascogale (Phascogale tapoatafa wambenger and P. calura) at the same locations within the same habitat and during the same survey event, something that has not been reported previously.

Abstract:

The morphology and bite performance of skulls of bats show a number of characteristic feeding adaptations. The great evening bat, Ia io (Thomas, 1902), eats both insects and birds (Thabah et al. J Mammal 88: 728-735, 2007), and as such, it is considered to represent a case of dietary niche ...

In response, hosts typically evolve anti-parasitism strategies, of which egg recognition is one of the most efficient. Generally, host egg-recognition capacity is determined using model eggs. Previous studies have shown that some host species, which are capable of detecting parasite eggs, do not reject model eggs ...

Abstract:
... Chelonians are mechanically unusual vertebrates as an exoskeleton limits their body wall mobility. They generally move slowly on land and have aquatic or semi-aquatic lifestyles. Somewhat surprisingly, the limited experimental work that has been done suggests that their energetic cost of transport (CoT) are relatively low. This study examines the mechanical evidence for CoT in three turtle species ...

Although ecological features, such as trophic group and species abundance, are thought to be more important for driving co-occurrence patterns at the habitat scale, it is not yet known if phylogenetic constraints can also exert some influence. Here, we studied gl ...
