“…Although 113 bat species are thought to be migratory, there is sufficient information to determine threats in only 25 (22%); similarly there is little, or no, information on the migratory status of about a third of small cetaceans (Riede 2001). Relatively few terrestrial mammals are migratory; most are large herbivores that follow seasonal vegetation growth (Berger 2004).…”

Long-distance migrations are among the wonders of the natural world, but this multitaxon review shows that the characteristics of species that undertake such movements appear to make them particularly vulnerable to detrimental impacts of climate change. Migrants are key components of biological systems in high latitude regions, where the speed and magnitude of climate change impacts are greatest. They also rely on highly productive seasonal habitats, including wetlands and ocean upwellings that, with climate change, may become less food-rich and predictable in space and time. While migrants are adapted to adjust their behaviour with annual changes in the weather, the decoupling of climatic variables between geographically separate breeding and nonbreeding grounds is beginning to result in mistimed migration. Furthermore, human land-use and activity patterns will constrain the ability of many species to modify their migratory routes and may increase the stress induced by climate change. Adapting conservation strategies for migrants in the light of climate change will require substantial shifts in site designation policies, flexibility of management strategies and the integration of forward planning for both people and wildlife. While adaptation to changes may be feasible for some terrestrial systems, wildlife in the marine ecosystem may be more dependent on the degree of climate change mitigation that is achievable.

“…In order to relate variation in encephalization and brain organization to ecology, species were grouped according to their primary lifestyle and habitat using information from previous studies [Last and Stevens, 1994;Tricas et al, 1997;Rosenberger, 2001a;Riede, 2004] as well as personal communications with C. Duffy (Marine Conservation Unit, Department of Conservation, New Zealand). Because ecological information is limited for the majority of the Australasian species that were investigated, habitat and lifestyle were scored simply as dichotomous variables.…”

Variation in Brain Organization and Cerebellar Foliation in Chondrichthyans: Batoids

et al. 2008

Interspecific variation in relative brain size (encephalization), the relative size of the five major brain areas (the telencephalon, diencephalon, mesencephalon, cerebellum, and medulla) and the level of cerebellar foliation was assessed in over 20 representative species of batoid (skates and rays), from eight families. Using species as independent data points and phylogenetically independent contrasts, relationships among each of the neuroanatomical variables and two ecological variables, habitat and lifestyle, were assessed. Variation in relative brain size and brain organization appears to be strongly correlated with phylogeny. Members of the basal orders Rajiformes and Torpediniformes tend to have relatively small brains, with relatively small telencephalons, large medullas, and smooth, unfoliated cerebellums. More advanced Myliobatiformes possess relatively large brains, with relatively large telencephalons, small medullas, and complex, heavily foliated cerebellums. Increased brain size, telencephalon size, and cerebellar foliation also correlate with living in a complex habitat (such as in association with coral reefs) and an active, benthopelagic lifestyle, but as primary habitat and lifestyle also closely match phylogenetic relationships in batoids, it is difficult to separate the influence of phylogeny and ecological factors on brain organization in these animals. However, the results of two forms of multivariate analysis (principal component analysis and cluster analysis) reveal that certain species are clustered with others that share ecological traits, rather than with more closely related species from the same order. This suggests that ecological factors do play a role in defining patterns of brain organization and there is some evidence for ‘cerebrotypes’ in batoids.

“…Although the Boddart's goggle-eyed goby Boleophthalmus boddarti (Pallas, 1770) is a commercial fish in some Asian countries [13,26] and has a wide range of salinity from marine to freshwater [32], its information has been limited to external morphology [10] and living habitat [8,28]. This gobiid species shows isometric growth [26] and feeds mainly on diatom [30].…”

ABSTRACT:The mudskipper Boleophthalmus boddarti is an amphibious fish widely distributed in the mudflat regions in Asia, but its reproductive biology was poorly stydied. This study was conducted in the Tran De, Soc Trang, Vietnam, from March 2013 to February 2014, to investigate reproductive parameters of B. boddarti. Data analysis based on a total of 360 collected fish (188 females and 172 males) suggest that the sex ratio of this mudskipper was not significantly different between dry and wet seasons. This fish was a multiple reproducer and spawned in the wet season with a peak spawning in three main months of this season (August to October) as difference stages of oocytes were observed in the ovaries. The male B. boddarti released sperms during the reproductive season since different type of spermatogonia were found in stage V testis sections. This fish reached 11.52 cm total length at first sex maturation and was high fecundity (9,800-33,800 eggs), indicating a possible adaptation of this species to the monsoonal climate. The understanding of the reproductive biology of B. boddarti provides useful knowledge of its reproductive adaptation to the mudflat toward sustainable management in the study region.
