Megjegyzések:	The dispersal of fish into distant and isolated habitats remains a topic of continuous discussion in the field of fish biogeography. This is particularly relevant due to the perceived limitation of fish movement to what is known as active dispersal. Fish migration is often confined to interconnected water bodies, underscoring the significance of dispersal for fish inhabiting isolated aquatic habitats. However, empirical evidence for a natural (i.e. not human-mediated) mechanism has been limited. Here we explore and provide evidence for waterbird-mediated endozoochory as a possible dispersal mechanism in various fish species and families. We force-fed mallards Anas plathyrynchos with fertilised eggs of nine bony fish species, covering nine taxonomic families. We recovered viable embryos of five fish taxa in the faeces of mallard, proving the ability of fish eggs to survive the passing of the digestive system of waterbirds. Moreover, the recovered eggs successfully hatched into larvae in two fish species. Taking into the flight speed and numerosity of mallards, as well as the high abundance of fish eggs, our results highlight endozoochory of fish eggs by waterbirds as a possible significant, although likely rare natural dispersal mechanism that can occur across more species than previously known in freshwater fish.

Cím:	Shorebirds as important vectors for plant dispersal in Europe / Ádám Lovas-Kiss, Marta I. Sánchez, David M. Wilkinson, Neil E. Coughlan, José A. Alves, Andy J. Green

Megjegyzések:	Shorebirds (Charadriiformes) undergo rapid migrations with potential for longdistance dispersal (LDD) of plants. We studied the frequency of endozoochory by shorebirds in different parts of Europe covering a broad latitudinal range and different seasons. We assessed whether plants dispersed conformed to morphological dispersal syndromes. A total of 409 excreta samples (271 faeces and 138 pellets) were collected from redshank Tringa totanus, black-winged stilt Himantopus himantopus, pied avocet Recurvirostra avosetta, northern lapwing Vanellus vanellus, Eurasian curlew Numenius arquata and black-tailed godwit Limosa limosa in south-west Spain, north-west England, southern Ireland and Iceland in 2005 and 2016, and intact seeds were extracted and identified. Godwits were sampled just before or after migratory movements between England and Iceland. The germinability of seeds was tested. Intact diaspores were recovered from all bird species and study areas, and were present in 13% of samples overall. Thirteen plant families were represented, including Charophyceae and 26 angiosperm taxa. Only four species had an ♭endozoochory syndrome'. Four alien species were recorded. Ellenberg values classified three species as aquatic and 20 as terrestrial. Overall, 89% of seeds were from terrestrial plants, and 11% from aquatic plants. Average seed length was higher in redshank pellets than in their faeces. Six species were germinated, none of which had an endozoochory syndrome. Seeds were recorded during spring and autumn migration. Plant species recorded have broad latitudinal ranges consistent with LDD via shorebirds. Crucially, morphological syndromes do not adequately predict LDD potential, and more empirical work is required to identify which plants are dispersed by shorebirds. Incorporating endozoochory by shorebirds and other migratory waterbirds into plant distribution models would allow us to better understand the natural processes that facilitated colonization of oceanic islands, or to improve predictions of how plants will respond to climate change, or how alien species spread.

Cím:	Predictors of forest fragmentation sensitivity in Neotropical vertebrates: a quantitative review / Daniela Vetter; Miriam M. Hansbauer; Zsolt Végvári; Ilse Storch
Dátum:	2011
ISSN:	0906-7590
Megjegyzések:	Species' responses to tropical forest fragmentation are variable and not well understood. Species' functional traits might help to reveal patterns of fragmentation sensitivity and provide valuable guidance to conservation practice. On the basis of 30 reviewed studies published between 1997 and 2008, we present a quantitative analysis of 730 responses of Neotropical vertebrates to forest fragmentation and habitat loss in terms of species' presence, abundance or fitness. Our intention was to identify possible ecological predictors of sensitivity to fragmentation, such as vertebrate group, feeding guild, forest dependency, and body size. We also controlled for methodology and study site characteristics, i.e. parameters studied, study design, study ID, and site ID. These ecological and methodological variables are frequently hypothesized to have an influence on reported fragmentation sensitivity. We conducted Linear Mixed Model analyses in order to relate the potential predictor variables to reported fragmentation effects. Model performance was assessed on the basis of AIC values. The best models included feeding guild, feeding guild + study design and feeding guild + forest dependency, respectively. We found that study ID and site ID significantly improved the models. Post-hoc tests revealed that nectarivores, possibly herbivores, and species able to use open habitats were affected significantly less by forest fragmentation than others. We therefore conclude that Neotropical nectarivores that are able to use open habitats are less negatively affected by forest fragmentation. Furthermore, a study site's characteristics will always be crucial in explaining observed fragmentation effects.
