Morphometric characterization of local geese in the Valley of Kashmir

open access: yesIndian Journal of Animal Sciences, 2014
An extensive study was carried out in the geese rearing areas of Kashmir Valley to record the morphometric parameters which included external body measurements and visceral measurements of local geese.

Size matters: relationships between body size and body mass of common coastal, aquatic invertebrates in the Baltic Sea [PDF]

open access: yesPeerJ, 2017
Background Organism biomass is one of the most important variables in ecological studies, making biomass estimations one of the most common laboratory tasks.

Evolutionary rates of body-size-related genes and ecological factors involved in driving body size evolution of squamates

open access: yesFrontiers in Ecology and Evolution, 2022
Body size is one of the most important traits of an organism. Among reptiles, both lizards and snakes show body size differences that span a similar six orders of magnitude variation.

Experimental harvesting of fish populations drives genetically based shifts in body size and maturation [PDF]

open access: yes, 2013
Size-selective harvesting in commercial fisheries can induce rapid changes in biological traits. While experimental and wild harvested populations often exhibit clear shifts in body size and maturation associated with fishing pressure, the relative ...

Body size determines eyespot size and presence in coral reef fishes

open access: yesEcology and Evolution, 2020
Numerous organisms display conspicuous eyespots. These eye‐like patterns have been shown to effectively reduce predation by either deflecting strikes away from nonvital organs or by intimidating potential predators.

Role of zooplanktonic functional groups in a shallow mesotrophic reservoir

open access: yesActa Limnologica Brasiliensia, 2023
: Aim Zooplankton functional groups play an important role in lake functioning and can readily respond to environmental changes and may be associated with phytoplankton changes.

Turbidity weakens selection for assortment in body size in groups [PDF]

open access: yes, 2015
Prey animals commonly associate with similar-looking individuals to reduce predation risk, via a reduction in predator targeting accuracy (the confusion effect) and preferential targeting of distinct individuals (the oddity effect).

The relationship between social network body size and the body size norms of Black and Hispanic adults

open access: yesPreventive Medicine Reports, 2015
Objective: To examine the relationship between the body size norms of Black and Hispanic adults and the body sizes of their social network members. Methods: Egocentric network data were examined for 245 adults recruited from 2012–2013 in New York City. A

Reduced strength and increased variability of extinction selectivity during mass extinctions

open access: yesRoyal Society Open Science, 2023
Two of the traits most often observed to correlate with extinction risk in marine animals are geographical range and body size. However, the relative effects of these two traits on extinction risk have not been investigated systematically for either ...

Testing mechanisms of Bergmann’s rule: Phenotypic decline but no genetic change in body size in three posserine bird populations [PDF]

open access: yes, 2011
Bergmann’s rule predicts a decrease in body size with increasing temperature and has much empirical support. Surprisingly, we know very little about whether “Bergmann size clines” are due to a genetic response or are a consequence of phenotypic ...
